Harjak

A mechanical wedge steel jack is a versatile and robust tool often utilized in various industrial and automotive applications for lifting, holding, or adjusting heavy loads. Comprised of a steel frame and a wedge mechanism, this type of jack operates on the principle of converting linear force into lifting power.

The wedge, typically driven by a screw or hydraulic system, slides in a controlled manner to lift or adjust the height of the load with precision.

The devices are ideally for temporary and permanent pre-loading solutions for bridge jacking, and temporary work schemes upto 200 tonnes.
