Loader crane manufacturer Palfinger has upgraded its Dual Power System (DPS) to DPS Plus. If the crane is equipped with a fly jib, it provides a lifting moment increase of up to 70%, according to the company.
The fly jib can be operated in two pressure ranges with an electronic overload protection system. If the last extension boom of the crane is fully extended (normal operation), the lifting capacity of the crane will be reduced to prevent overload. If the last extension boom of the crane is retracted (DPS activated), the system automatically switches to the high pressure range and thus uses the maximum lifting capacity of the fly jib. It also enables an increase of up to 15% lifting capacity when the last extension boom is fully extended.
DPS Plus is available on all machines rated 40 tonne-metres and above.
