Hydraulic jack A jack that uses a plunger or hydraulic cylinder as a rigid jacking member. It has the characteristics of compact structure, stable working, large top holding force and self-locking.

SOLY ultra-low thin series jacks usually have excellent performance in bridge engineering, and the heavy duty series hydraulic jack top support force exceeds 1000t.
Hydraulic jack models for various application scenarios are complete, custom parameters are customized, and engineers help develop complete solutions.

SL-TM On-rail heavy load transfer machine

SL-TM Railway Track Heavy Object Pusher

The on-rail weight pushing machine (referred to as the moving machine) is composed of two parts of the clamp and the moving cylinder, which has been widely used in the country’s large transportation industry, and is equipped with the corresponding ultra-high pressure electric oil pump station and auxiliary devices for moving operations. Users need to bring their own heavy rail (38kg/m, 43kg/m,50kg/m) and active and passive boots. In order for the weight to be moved to run smoothly, two sets of push machines must be used at the same time.
At present, it has been widely used in the national heavy load transportation industry.

RL-RR Double Acting Hydraulic Cylinder Jack

The plunger within a double acting hydraulic cylinder uses hydraulics to both advance the plunger and also to provide a faster and more precisely controlled retraction. This makes them ideal for jobs requiring repeatable accuracy, fast retraction or push and pull forces.
SOLY offers a wide range of customised double acting hydraulic jacks in various models and powers.

SL- BLQ Hydraulic Jack Step Type

Intelligent walk-behind jacking equipment is mainly composed of jacking device, hydraulic pump station and control system and pipeline. Each set of jacking device controls the operation of hydraulic jacks through computer control of fluid force and supply flow to realize combined and sequential actions, with synchronization accuracy of 0.2mm, which fully meets the construction requirements.

SL-RRH Double acting hollow cylinder / Double acting hollow jack

SL RRH Double Acting Hydraulic Cylinder

A double-acting hydraulic cylinder is a hydraulic cylinder that can input pressure oil from both sides of the piston. It is often used as a drive assembly for jacks. The actuator of a double-acting hydraulic cylinder is the main output device of a hydraulic motion system, and although it varies in size, type, and design configuration, it is usually the most visible part. These actuators convert fluid pressure into rapid, controlled linear motion or force to drive a load.
Safety valve for protection in case of overload, double acting for quick return, hollow plunger allows thrust and pulling force.
