Welcome to Jiangsu Yuli Electromechanical Equipment Group Co., Ltd.!
Position:Home - Products - Hydraulic cylinder series - Hollow hydraulic jack
Double acting hollow hydraulic jack

It is suitable for all kinds of testing, maintenance and applications requiring tensile force.

The hollow plunger design can be used for both pulling force and thrust force.

Double acting, hydraulic return stroke, higher working efficiency.

The surface is treated with corrosion resistance, bright and not easy to rust.

Alloy steel is heat treated and processed by imported CNC lathe, drilling machine and grinder.

Seals make the oil cylinder difficult to wear when working continuously.

The plunger head is heat-treated, so no saddle is required.

  • Features

The hollow piston rod can pass through the steel bars; the overflow hole is installed and the limit function is provided.

It is used in the disassembly and assembly of main shafts and tail shafts of various shipyards, nuclear power plants, tunnel projects, underground projects, construction and other occasions to realize the pre-tightening process and other occasions that require push and pull.
