Best in class performance and serviceability
• The steel torsion box and flatbed further reduce frame flex
• Speedy-reeve boom tip and sheave blocks simplify rigging changes by decreasing the time needed to change line reeving
• Crane components painted before assembly reduce the chance of rust, improve serviceability and enhance the appearance of the crane
• A control knob located on the swing motor brake release valve can be easily adjusted to the crane operator’s swing speed preference
• Engine start/stop switches
• Emergency stop overrides located at the crane operator control station
• Hydraulic reservoir capacity of 66 gal
Serviceability
• Bearings on the boom and retract cables can be greased through access holes in the boom side plates.
• Removable winch allows the internal telescoping cylinder to be removed quickly, without dismantling the boom
• Internal anti-two-block wire routing eliminates external reel and wire to protect crane components
• The boom sheave case is open, allowing access to replace the internal anti-two-block wire and to observe internal boom components
• Internal boom parts have been reduced, decreasing service time when rebuilding the machine
