Pull Cylinders for Hydraulic Pulling Applications

Pull Cylinder

Pull cylinders are similar in design to double-acting differential cylinders, but have a special mode of operation: While there are hydraulic connections on both the piston and rod sides, only the rod side is actively pressurised. This results in a targeted pulling movement, while the return movement is achieved by external forces such as the system's own weight. This design enables efficient, powerful and precise control of tensile forces. 

Advantages of our pull cylinders

Efficient power transmission

Developed to transmit high tensile forces and enable precise movements.

Robust construction

High-quality materials and precision manufacturing ensure a long service life and low maintenance costs.

Versatility

Suitable for a wide range of applications requiring tensile forces.

Individual design

Designed exactly to the customer's specific requirements for optimum integration and performance.

Areas of application

Pull cylinders are used in numerous applications, especially where precise pulling movements are required.

Typical areas of application are:

Hydropower

In Dams, movable bridges, lock technology, flood prevention

Cranes

In mobile and harbor cranes 

On-/offshore & oil, gas

In jack-up and construction vessels

Mining

In conveyor systems and mining machines to support traction movements.

Mechanical engineering

In lifting platforms, clamping devices and other machines that require tensile forces.
