WINCOO Chuck Type Hydraulic Jacks
Engineered for Precision, Safety & Heavy Load Performance
Product Overview
The WINCOO Chuck Type Hydraulic Jack is a double-acting hydraulic lifting system featuring upper and lower clamping heads divided into two independent bodies. The system utilizes a double-acting hydraulic jack working 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 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 during power failure, hose rupture, or component malfunction, the load remains securely held without falling.

Features & Advantages
- Double-Acting Hydraulic Design – Provides controlled vertical lifting with precise force application, ensuring stability for heavy loads.
- Patented Upper/Lower Clamping Mechanism – When oil enters the jack, the upper clamp fastens and lifts the lifting rod and expansion ring; when oil returns, the upper clamp returns with the piston and the lower clamp automatically fastens the lifting rod without gliding.
- Compact Design with High Capacity – Small volume, light weight, and large bearing capacity for convenient installation in small spaces or indoor large-tonnage component lifting.
- Reverse Movement Self-Locking – Allows the lifting process to be locked at any position for extended periods, providing exceptional safety during long operations.
- Multiple Operation Modes – Automatic operation, semi-automatic operation, single point adjustment, and manual control modes with LCD display, touch screen display, and button operation panel.
- Efficient & Cost-Effective – Short construction period and low cost with reduced equipment overhead and faster project completion.
Applications
- Tank maintenance (elevating tanks for foundation inspection and repair)
- Heavy structure installation (reactors, modules, ship sections)
