WINCOO
WINCOO ENGINEERING CO., LTD., a leading manufacturer with over a decade of experience in hydraulic lifting solutions, proudly presents its Chuck Type Hydraulic Jacks — a high-performance double‑acting hydraulic lifting system engineered for the inverted construction of large‑scale steel storage tanks, grain silos, enamel tanks, and other heavy industrial structures. Designed with a patented upper and lower clamping head mechanism, the WINCOO Chuck Type Hydraulic Jack delivers exceptional lifting accuracy, operational reliability, and long‑term durability under the most demanding job site conditions.
At the core of the system is a double‑acting hydraulic jack (also known as a hydraulic lifting machine) with two independent clamping heads that work in synergy with a lifting rod to achieve reciprocating lifting motion. When hydraulic oil is supplied, the upper clamp secures the lifting rod and expansion ring, lifting the tank (including the roof) upward. Upon oil return, the lower clamp automatically engages to prevent any sliding or unintended descent — a design that guarantees true load‑holding safety. This intelligent self‑locking feature ensures that even in the event of a power failure, hose rupture, or component malfunction, the load remains securely held without falling.
Built to handle rated lifting capacities ranging from 12 to 120 tons, with a maximum height from 1 to 4 meters, the WINCOO Chuck Type Hydraulic Jack is available in a variety of specifications and models (such as the SQD‑XXX‑100S.F series) to suit different project scales. The system is certified with CE and ISO 9001:2000, reflecting WINCOO‘s commitment to international quality and safety standards.
The complete system comprises a PLC‑controlled hydraulic pump station, hydraulic cylinders, and rectangular steel frames — all designed for fast installation and convenient on‑site operation. The pump station can be placed inside the tank, outside the tank, or between two tanks when controlling two units simultaneously, offering remarkable on‑site adaptability. The PLC control delivers high synchronization precision among multiple jacks, preventing structural twisting or bending during the lifting process.
Key operational advantages include:
High degree of automation — supports automatic, semi‑automatic, single‑point adjustment, and manual control modes.
Hydraulic and pin‑lock dual safety mechanism — ensures zero‑slip load retention even during prolonged lifts.
Adjustable lifting height with fine‑tuning capability — allows precise butt‑alignment of tank wall plates for superior welding quality.
Robust corrosion‑resistant steel construction — built to endure harsh industrial environments and harsh weather conditions.
From the petrochemical sector to bulk storage facilities, the WINCOO Chuck Type Hydraulic Jack is the go‑to solution for contractors and engineers who demand controlled, stable, and highly productive lifting operations. With OEM customization options — including lifting rod specifications, load capacity adjustments, and pump station configurations — WINCOO delivers a truly tailored lifting solution that evolves with your project needs.
