Hydraulic Force Control
Excessive clamp force caused by too much hydraulic pressure is one of the most common causes of damage to paper rolls.
Mechanical 3-position relief valves are under-utilised or primarily left on the high setting.
Hydraulic Force Control (HCF) solves these issues by automatically adjusting clamp force. HCF is a hydraulically controlled automatic clamp for system that changes the clamp force proportional to the load weight.
It works by continually sensing the hydraulic pressure necessary to lift the load and adjust clamping pressure as the weight of the load increases or decreases. The system operated without any special actions on the part of the driver.
