Simple chain type hydraulic jacking system is composed of one-stage double-acting hydraulic cylinder, pulley block, load-bearing chain and oil way etc. Moveable pulley is used to enlarge chain stroke, i.e. traveling distance of the cylinder is 1/2 of lifting distance of the chain. It applies to inverted installation and construction of various large storage tanks (steel) and various storage tanks.
LYT-type simple chain type hydraulic jacking system includes the following models: LYT-120-2700, LYT-200-2700, and LYT-300-2700 etc. (those with special stroke need to be customized).

What are the advantages of simple chain type hydraulic jacking system?
LYT-type simple chain type hydraulic jacking system is used to firstly lift the tank roof and the top (first layer) siding of the tank. It's required to group weld tank siding when the lifting height of siding exceeds the second siding (the second layer from the top) by 30-50mm, and group weld the third layer (the third layer from the top to the bottom) of the tank after lifting again, lift successively, group weld the siding of the tank layer by layer, until the last layer of siding.
LYT-type simple chain type hydraulic jacking system is used for lifting. When oil enters the hydraulic jack, the movable pulley is pushed upward by pressing the piston, thus driving the load-bearing chain to lift the expansion ring. In this way, the whole tank (including tank roof) is lifted up, until it reaches the pre-set height (there is a voidance of the next layer of plate). The siding in this layer is surrounded for butt welding. After the positioning block is welded, hydraulic hoist returns and the lift tank falls back to the newly-surrounded siding. After welding of circular seam and vertical seam, the door-type card for fixing expansion ring is cut off and the expansion ring is released. In this way, the hoist returns and expansion ring falls to the Model of hydraulic pump station Tank volume Rated pressure Rated flow Power Control voltage of solenoid valve Motor drive rate YB-7.2 220L (700*550*580) 25Mpa 7.2L/min Three-phase Four-wire (380V) 220V 5.5KW YB-14.5 340L (750*650*650) 25Mpa 14.5L/min 220V 7.5KW Mode of LYT-type hoist Rated lifting capacity (KN) Hydraulic area (mm) Rated oil pressure (MPa) Piston stroke (mm) Chain stroke (mm) Cylinder safety equipment Reinforcement measures LYT-120-2700 120 11304 25 1500 2700 Double-direction oil-way hydraulic lock 2 adjustable pull rods LYT-200-2700 200 18859.6 25 1500 2700 Double-direction oil-way hydraulic lock 2 adjustable pull rods LYT-300-2700 300 25434 25 1500 2700 Double-direction oil-way hydraulic lock 2 adjustable pull rods bottom of tank siding. Then, the next circular plate is expanded and transfer rib plate, such as door-type card, is welded for lifting, and so forth. The group welded tank is lift, until group weld of the last layer of siding, so that the whole storage tank is installed with this inverted method.

As the founder and disseminator of hydraulic hoist, WINCOO has been building the inverted hydraulic jack and production technology of installation engineering for a long time.We are going to explain how to use the hydraulic jack safely.
●Safe operation code of hydraulic jack
●Precautions for the use of hydraulic jack
●How to repair and maintain hydraulic roof in daily use
1. Hydraulic lifting equipment must be operated by specialized operators;
2. Ground wire must be installed for hydraulic pump station;
3. Check whether motor is rotating in pump indicated direction after startup; motor for this equipment is step-down startup with six second interval. Supply oil for jack after full start of the motor; exhaust air in system via exhaust valve before lifting;
4. Rated pressure for hydraulic system is 25Mpa and pressure indication of pump station pressure gauge cannot exceed 26Mpa;
5. Check clamp block of upper and lower clamps for slip during jack lifting. If block teeth are filled with foreign matters, clean on time and clean the taper sleeve outside block. Grease the taper surface to reduce sliding friction between taper surface and block arc; if teeth shaped surface is severely worn more than 0.4mm, replace block on time. Remove upper and lower clamps and clean after each project. Check wear condition and replace when necessary;
6. Check whether exhaust valve is closed before lifting;
7. Increase pressure slowly during adjustment;
8. System pressure can be at 28Mpa for a short time. Avoid long-term operation for damaging the system;
9. Do not crash high pressure oil pipe with hard objects. Avoid welding slag scorching. Replace high pressure rubber pipe for loss on time;
10. Release the pressure in system via exhaust valve when replacing hydraulic components;
11. Lift jack for a few millimeters when loosening clamp. Unload lower clamp and loosen it;
12. Loosen all lower clamps for butt joint and check; if looseness is inadequate, do not descend jack for opposite joint to avoid lower clamp damage;
13. Adjust pressure precisely when jack is ascending or descending in place. Do not put solenoid valve at neutral position to avoid instantaneous overvoltage;
14. Long-term overload operation is prohibited;
Hydraulic oil level in oil tank should be regularly maintained to normal level. Due to large capacity chamber of piping and hydraulic cylinder, it is mostly required to fill adequate hydraulic oil. After startup, hydraulic oil enters pipeline and cylinder, oil level decreases and filter even shows above oil level. Replenish hydraulic oil once again. It’s inevitable that hydraulic oil has loss during use, therefore, observe oil level regularly and replenish on time to maintain it at the middle position of level meter;
Hydraulic oil shall be kept clean always. Use oil filter vehicle when filling hydraulic oil with filtration precision below 30υm;
Replacing cycle for hydraulic coil is one year for normal operation;
Discharge all residual oil in tank when replacing hydraulic oil and refill after cleaning the tank. Filtration precision of new oil shall not be lower than precision of the system. Oil amount in tank shall be maintained within fixed level range;
Oil temperature shall be appropriate, not more than 60℃. Check for abnormal oil temperature rise. Start hydraulic pump and operate as required after oil temperature reaches 15 ℃ during winter;
Pay attention to the following for initial startup of hydraulic pump:
1) Hydraulic oil level in the tank shall be at the full position of vernier;
2) Check rotation direction of motor and it shall be clockwise seen from motor tail (arrow direction). If the direction id reversed, stop immediately and regain operation after handling;
3) Step up after 10 minutes’ idle operation of pump station;
Pay attention to check return oil filter. Replace cartridge for damage on time;
Before starting and stopping hydraulic pump, unload the overflow valve;
Spares for wear parts (seal ring, clamp block, etc.) shall be available at all times for timely replacement;
Set pressure of overflow valve cannot exceed maximum pressure of hydraulic system;
Check and maintain the jack before operation to ensure there is no oil leakage, clamp and the whole machine is in good condition;
When inserting lifting rod, the jack shall be loosened (loosening nuts at upper and lower clamps are screwed upward in place). Note that lifting rod and jack shall be almost concentric. Reset upper and lower clamps for normal operation and make the jack in operating state;
Prevent mud and sand from entering hydraulic rubber pipes during connection to avoid damaging hydraulic system and the jack;
Overpressure (overload) is prohibited during operation;
Lifting height shall exceed 20-30mm of coaming height and make jack piston at middle position for butt weld;
Make the jack at lifting state when descending the rod and oil pressure cannot be higher than that during lifting, that is to adjust oil pressure below that during normal lifting and then loosen lower clamp. After the jack is back stroke and lifted steel plate falls on newly surrounded plates, the jack bears no load. Loosen upper clamp and lifting rod descends;
According to actual ambient temperature, it is decided to use N46 anti-wear hydraulic oil for the system and mix of other grades is prohibited;
Clean and maintain the jack on time after one project, especially attachment at clamp block teeth. Replace for severe teeth wear and repair the replaced jack.

In recent years, large-scale pipeline projects have started one after another, and the level of mechanical equipment of pipeline construction solutions has been steadily improved. However, the management of pipeline construction equipment on the construction site has not kept up with the speed of pipeline engineering and mechanical equipment updates, resulting in a high rate of equipment failure and maintenance on the construction site. High cost, low technical performance and low utilization rate. In response to these situations, explore standardized maintenance in the management of pipeline construction equipment.
Here is the content list:
l Regarding the maintenance status of pipeline construction equipment at the construction site.
l What are the specific measures to achieve standardized maintenance of pipeline construction equipment?
l How can companies ensure the effective implementation of pipeline construction equipment maintenance procedures?
l Objective conditions cause pipeline construction equipment maintenance to be unable to be carried out normally. Pipeline construction has a large geographic span, harsh construction environment, and increased equipment component wear, which directly affects the stability and reliability of the equipment, causing the mechanical equipment to lose basic performance and fail to operate normally. In addition, the current project schedule is very tight. In order to catch up with the schedule and grab the schedule, it is difficult to keep up with the daily maintenance of pipeline construction equipment.
l Subjectively neglect.The subjective factor that causes the on-site pipeline construction equipment maintenance to be unable to be carried out normally is that the relevant units and management personnel do not pay attention to the equipment management. In many construction companies, the management of the company, project management, and construction crews do not pay much attention to the management of pipeline construction equipment, believing that the equipment is just a tool for wear and tear during the construction process, which emphasizes use rather than maintenance. Many construction projects and construction units arbitrarily extend the maintenance cycle of pipeline construction equipment, reduce the grade of accessories and lubricants, so that the overhaul cycle of the engine is shortened due to human factors, project maintenance costs increase, and the cycle of equipment failures is prolonged. The technical performance of pipeline construction equipment has severely declined.
l Weak technical management capabilities.The quality of equipment maintenance has declined. First of all, many on-site management personnel's understanding of on-site maintenance of pipeline construction equipment is still at the level of "replacement of the three oil filters", and the maintenance of the engine, chassis and working devices is not included in the pipeline construction equipment. Maintenance plan in progress. Secondly, the equipment operators and maintenance personnel do not have a high level of basic skills and cannot complete the overall overhaul of pipeline construction equipment with high quality.
Repair and maintenance of pipeline construction equipmentt is very important. First of all, we must regularly check, maintain and replace vulnerable parts. WINCOO will provide manuals with the machine, such as high-performance pipeline construction equipment, automatic pipeline construction equipment, small pipeline construction equipment, high-precision pipeline construction equipment, easy-to-maintain pipeline construction equipment, etc. The following are specific measures:
① In view of the low maintenance quality of pipeline construction equipment, by compiling comprehensive, meticulous, and highly operable procedures, not only can we clarify what tasks the pipeline construction equipment operators and maintenance personnel need to do daily maintenance and secondary maintenance, but also tell them How to work.
② While compiling maintenance procedures for pipeline construction equipment, the company also compiled checklists for standardized maintenance and management of various types of pipeline construction equipment, making it the main basis for management departments at all levels to inspect pipeline construction equipment, and unify inspection standards and assessment scores. Standards to facilitate the recording, filing and review of equipment inspections and inspection results.
① Personnel training. Strengthen the learning and training of pipeline construction equipment supervisors,managers, and maintenance personnel to change their concepts, fully understand the importance of maintenance to the use of equipment, and cultivate long-term perspectives and implementation of pipeline construction equipment maintenance, and completely avoid the first phase The situation where the project "eaten" a batch of pipeline construction equipment. Through regular learning and training, the standardized equipment maintenance procedures are deeply rooted in the hearts of the people, and become the working guidelines and working habits of operators and repairers, rather than the work requirements of the superior management department. Through learning and training, to a certain extent, the sense of responsibility and dedication of managers at all levels has also been improved.
② Innovate the system of deciding people and machines. In order to mobilize the enthusiasm of equipment operators to rationally use pipeline construction equipment, earnestly maintain pipeline construction equipment, and sincerely care for pipeline construction equipment, the company strictly implements the system of determining personnel and equipment, and integrates the personnel and equipment management information system to control the attendance and equipment of the operators. The intactness of the pipeline construction equipment is linked together, and the man-hours for equipment maintenance are included in the actual man-hours of the operator.
① Increase the intensity of rewards and punishments for pipeline construction equipment inspection. In order to ensure the implementation of the standardization of pipeline construction equipment on-site maintenance, the company pays special attention to the intensity of inspection rewards and punishments for pipeline construction equipment when revising the management system.
② Link the maintenance of pipeline construction equipment with bonuses. In order to motivate the construction unit to use and maintain the pipeline construction equipment, the project department regards equipment maintenance as an important assessment index when formulating the economic responsibility system assessment, guiding the construction unit to use the maintenance pipeline construction equipment rationally, controlling the construction progress and avoiding the problem to the greatest extent.
In order to ensure that pipeline construction equipment maintenance procedures can be effectively implemented, the company has formulated corresponding management systems and adopted specific measures to supervise the implementation of these systems.
l Divide maintenance responsibilities. In the management system, the corresponding responsibilities of equipment operators, pipeline construction equipment maintenance personnel, unit equipment managers, and project pipeline construction equipment managers are clarified, and these responsibilities are written into the maintenance procedures manual of each type of equipment, so that all levels of pipeline construction equipment Managers can see what they should do every day and how to record their work in the maintenance procedures.
l Promote standardized pipeline construction equipment maintenance procedures. Implement standardized equipment maintenance organization processes in each construction project to ensure smooth equipment maintenance channels and optimize the maintenance force of the entire project.
l Establish a professional maintenance team. The project department mobilizes skilled fitters, electricians, and repairers to form a professional maintenance team, which is conducive to the unified scheduling of maintenance forces for the project, and ensures low failure rate and high utilization of pipeline construction equipment.
What is more? WINCOO provide not only pipeline construction solutions, but also pipe spool fabrication solutions for customers from everywhere!
The hydraulic storage tank lifting equipment adopts the working principle of the straight top of the hydraulic oil cylinder, which can lift the lifting work table to a certain height and complete the transportation of the goods, which greatly saves manpower. The application range of hydraulic storage tank lifting equipment lift is very wide. Warehouse workshop, supermarket logistics station, and home can be installed and used, the safety factor of hydraulic storage tank lifting equipment lift is relatively high.
What should we pay attention to before using the hydraulic storage tank lifting equipment?
What should be paid attention to during the use of hydraulic storage tank lifting equipment?
What are the steps of using hydraulic storage tank lifting equipment?
1) Before use, it is necessary to check whether all parts of the hydraulic storage tank lifting equipment are normal, mainly check whether the piston, joints, high-pressure hoses, etc. leak oil.
2) The regulations in the main parameters should be strictly followed during use, and super high overload should be avoided, otherwise, when the lifting height or lifting tonnage exceeds the regulations, serious oil leakage will occur at the top of the hydraulic cylinder.
3) If the oil in the manual hydraulic pump is insufficient, it is necessary to add fully filtered hydraulic oil to the pump before it can work.
1) The choice of the center of gravity of the heavy object should be moderate, the focus point of the hydraulic storage tank lifting equipment should be selected reasonably, and the bottom surface should be flat. At the same time, the soft and hard conditions of the ground should be considered, whether it should be lined with tough wood, and whether the placement should be stable, so as to prevent the load from sinking. or inclined.
2) After the hydraulic storage tank lifting equipment lifts the heavy object, the support should be used to support the heavy object in time.
3) If several hydraulic storage tank lifting equipment need to be lifted at the same time, in addition to the correct placement of the jacks, attention should be paid to the balanced load of each hydraulic storage tank lifting equipment, and attention should be paid to keep the lifting speed synchronized to prevent the objects being lifted from tilting danger occurs.
1) When using the hydraulic storage tank lifting equipment, first place the hydraulic cylinder, and then tighten the oil drain screw on the hydraulic pump to work. To make the piston rod descend, loosen the handwheel of the manual hydraulic pump in a counterclockwise direction slightly, the hydraulic cylinder is unloaded, and the piston rod gradually descends. Otherwise, it will be dangerous to descend too fast.
2) The detached hydraulic storage tank lifting equipment adopts a spring reset structure. After lifting, it can be quickly taken out, but the connected hose cannot be used to pull the jack.
3) Due to the small lifting stroke of the jack, the rated stroke should not be exceeded during use to avoid damage to the jack.
4) The violent vibration of the hydraulic storage tank lifting equipment should be avoided during use (such as hitting the workpiece with a hammer when the hydraulic storage tank lifting equipment is loaded).
For many years, WINCOO ENGINEERING CO., LTDhas been a trustworthy supplier in the hydraulic storage tank lifting equipment area. If you choose this company, you will get the best quality products and the most intimate after-sales service.

3. Clean the groove
The Angle grinder is used to clean up the oil and rust in the groove, remove burrs, splashes and solder spots on the groove surface. The lower vertical joints of the steel plate are ground to 100mm, and the contact points between the upper vertical joints and the transverse joints are handled well to make the bottom of the groove smooth and smooth, so as not to hinder the movement of the pallet along the steel plate.
4. Install the welding wire
Put the wire into the wire tray for fastening, and then cut off part of the bundled string.
A hose should be added between the welding wire plate and the welding gun to avoid electric leakage between the welding wire and the body.The pressing force of the straightening wheel should be small to avoid bending of the welding wire caused by excessive pressure.After the welding wire is inserted into the gun barrel, close the wire feeding pressing wheel and press the "wire feeding" button to send the welding wire out of the conductive nozzle for a length. At this time, all the binding ropes are cut open.The pressing degree of the pressing wheel should be appropriate. If it is too loose, it will cause the wire to slip. If it is too tight, it will cause the wire indentation to be too large, and the resistance will increase, leading to the instability of the welding arc.When the conductive tip is worn too much, it must be replaced in time, otherwise the conduction is not reliable, and it is easy to cause the welding arc instability.
5. Filling flux
The flux shall be dried with a special drying box, and the heating temperature shall be as per the requirements of the flux. After heating, the flux shall be kept warm to about 50℃.When the flux temperature is too high, it can not be loaded into the flux box, so as not to burn the flux pipe.Pay attention to clean the dust on the filter cover in the flux box to ensure the suction of recovery.
6. Adjust the torch
Adjust the position and Angle of the welding torch so that it is in the center of the supporting belt.Operator requires that the stretching length of the wire is 20-30mm, that is, the distance between the conductive tip of the welding gun and the steel plate. The Angle of the welding gun is generally about 25 degrees.
7. Adjust the flux transport and recovery system
Adjust and operate the roof wheel, so that the tray is separated from the steel plate. Adjust the supporting belt on the tray to about 15-20mm below the groove, and then remove the roof wheel from the steel plate, so that the supporting belt contacts the tank wall, and test the operation for about 1M to check whether it is in normal operation.Adjust the relative position of the conveying port and the welding gun to ensure that the welding flux can fully protect the welding point;Adjust the position of the recovery port to ensure that all unreacted flux can be recovered to the flux tray.
8. Check whether the welding power switch is correct, whether the ground wire contacts and conducts well, check whether the switch behind the operation box is in the "automatic" position, and close the welding power switch.
9. Adjust the wire does not contact the steel plate, open the wire feed pressing wheel, press the "start" button of welding, at this time the voltmeter is displayed, adjust the voltage to 35V, and adjust the current to make the wire feed wheel speed is appropriate, press the "stop" button.(This work is mainly to ensure that the arc is easy to start after welding, the welding current and arc voltage are stable and the arc is normal.)
