PB - Power Boost

PB system can reach longer outreach with very heavy load, with the highest precision.

Power and precision
F.lli FERRARI Power Boost (PB) enables the crane to reach further and lift more. This is accomplished by reducing the oil flow through a flow divider and increasing the maximum available pressure. In high load conditions, this gives the operator more control and lift capacity. PB engages and disengages automatically, so there is no reduction in speed during light/medium crane loading.

Hydraulic version
In normal conditions, all of the oil flow from the pump enters the control valve. When the PB engages, part of the oil flow returns directly the the tank (blue line) and the remainder enters the control valve (red line).

Electronic version
On cranes equipped with RDC and PB, the speed reduction is achieved through the radio control instead of a flow divider. Only certain functions are subject to a speed reduction, and at individual percentages. The crane retains the maximum operating speed possible without compromising safety.
