7-axle truck mounted knuckle boom from PM
By Euan Youdale23 March 2011
PM has introduced an 85 tonne-metre rated articulated loader crane on a 7-axle truck to provide additional payload.
The PM 85028-S knuckle boom has been shown in the USA for the first time at ConExpo. The model has an eight extension boom with up to 67 feet, 9 inches (21 metre) horizontal reach.
It is mounted on the new Kenworth T800 truck with tandem steer and three raised axles. The truck is powered by a 525 hp Cummins engine. The new 20 x 8 foot (6 x 2.4 m) flat deck design is extendable to 25 feet (7.6 m).
Stefano Ghesini, PM sales director, said it is the first time an articulated loader has been mounted on a seven axle truck. It offers a payload of 23,000 pounds (10.4 tonnes).
The main applications will be in construction, precast materials and rigging. Ghesini said knuckle booms are becoming increasingly popular and as rental companies replace their fleets he expects sales to rise. "Customers are now understanding the advantages."
