Hydraulic storage tank lifting equipment is a kind of jack that uses a plunger or a hydraulic cylinder as a rigid jacking member. Simple lifting equipment is generally only equipped with a lifting mechanism to lift heavy objects.
Why do we maintain hydraulic storage tank lifting equipment in the right ways?
Why can't the hydraulic storage tank lifting equipment lift go up?
What are the advantages of hydraulic storage tank lifting equipment?
(1) The bottom of the hydraulic storage tank lifting equipment should be flat and tough when used. Oil-free planks to expand the bearing surface and ensure safety. Can not use iron plate instead of wood, to prevent sliding.
(2) When lifting, it is required to be stable. After the heavy object is lifted for a while, it is necessary to check whether there is any abnormality. If there is no abnormality, the roof can continue to be lifted. Do not lengthen the handle arbitrarily or operate it too hard.
Most of the hydraulic storage tank lifting equipment lift hydraulic power source is used for lifting and lowering operations. With the aging of the mechanical structure, some small faults will inevitably occur after long-term use, such as the lift does not lift, so what is the reason? The hydraulic lift cannot afford There are many reasons for the rise, the common ones are:
1. The load is too heavy, exceeding the rated load, and the load can be reduced.
2. The oil return valve is not closed, causing the hydraulic system to not work normally, and the oil return valve needs to be tightened.
3. The filter is blocked, replace or clean the filter.
4. If the hydraulic oil is insufficient, add enough hydraulic oil to the lift.
Main features of hydraulic storage tank lifting equipment:
1. The system consists of hydraulic pump station, oil cylinder, steel wire and stroke. Easy to install and operate;
2. The system adopts PLC central control to handle elevators. Each power pack is equipped with an auxiliary balance device to ensure the accuracy of simultaneous lifting;
3. The hydraulic lifting pump station has two operation modes: auxiliary manual control and central control. The cylinder can be adjusted to lift individually or in multiple groups, or in combination with multiple groups to achieve better precision and better welding effect;
4. All cylinders are equipped with safety valves. In the event of power failure, high-pressure hose rupture, burst, etc., it can be automatically locked to prevent the cylinder/fuel tank from falling.

As a large-scale equipment specially designed and developed for the national oil reserve project, the YT series tank hydraulic jacking system is suitable for the upside-down welding process engineering of large steel silos.
Tank hydraulic jacking system is the welding engineering of giant steel silo upside-down technology, suitable for steel storage tanks with height ≤ 2.5 meters. The specific usage method is as follows:
l The overall structure, the vertical lifting displacement of the overall building.
l Inverted construction of large-span roof trusses and multi-story buildings.
l Large objects are lifted vertically.
Tank hydraulic jacking system of equipment is a two-stage single-acting hydraulic cylinder (hydraulic jack), used for VTOL force or force that needs to return from the rear, so it cannot be used for horizontal work.
In addition, tank hydraulic jacking system is a compact device, safe and stable, easy to operate, adjustable load, fast installation, and high synchronization accuracy.
YT series tank hydraulic jacking system is used as a "drag five" oil supply device. Each pump station is connected to the hydraulic cylinder 5, thus avoiding the disadvantages of excessive and leaking caused by traditional centralized oil pipes and ensuring environmental pollution Minimize!
YT-C type hydraulic storage tank lifting equipment is a set of large hydraulic lifting equipment specially developed by our company for national crude oil reserve project in 1994.As long as the number of hydraulic cylinder and pump station system is increased or decreased, this type of equipment can be applied to the inverted construction of large storage tanks with different volumes ranging from thousands of cubic meters to hundreds of thousands of cubic meters.
The control part adopts Siemens PLC modular design concept, simple operation, reliable quality.The hydraulic cylinder can be used for single or multiple lifting height adjustment, and can also be used for centralized control of multiple groups.Through more than ten years of practice summary, we continue to optimize the equipment, improve the production process, so that the product quality and performance greatly improved, the majority of users praise.
1, The hydraulic lifting equipment is evenly placed inside the jacked tank. The overall force and lateral force of the equipment are calculated strictly and successfully applied.
2, The structure is rigorous and compact, the output force is adjustable, the jacking speed meets the jacking requirements, and the synchronization accuracy is high.
The transfer of force: output force of hydraulic cylinder → steel wire rope → rising ring (welded with lifting lug) → rib plate for transferring force → tank wall jacking
Jacking control process:
1, Pump station control box (rotating selection button) → Centralized control operation box (Figure 1-3) → hydraulic jacking pump station (solenoid of valve group) →PLC devices → centralized control operation box → hydraulic jacking pump station → integral or partial lifting or lowering of hydraulic cylinder.
2, Pump station control box (rotating selection button) → control handle → hydraulic cylinder (single or multiple) fine adjustment up and down.
