Progressive crane control - PCC

Avoid dangerous oscillations

The Progressive crane control function (PCC) dampens oscillations in the crane structure. The spool movement is captured before the oil flow is led to the hydraulic cylinders, whereby oscillations in the suspended load are reduced.

Ensures a longer life span for your crane

The PCC function is purely electronic and dampens both mechanical and hydraulic oscillations in case of sudden movements by means of the control valve levers. This protects the crane’s structure against wear and damages.

PCC intervenes only when needed

The function does not influence the grab functions - they will still be sudden and abrupt for efficient emptying of a clamshell bucket. Small movements and slow operation of the crane functions will not be influenced either.

Better operation safety and comfort

A smooth operation of the crane gives the operator a better comfort, and above all prevents dangerous situations due to unintended oscillations. Moreover, efficiency is increased as the operator does not have to take disturbing oscillations into account.
