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

Previously, the 647E2 and 680E2 models were part of the 600E2 Series.  While these two models are no longer in production, they are still fully supported by the Manitowoc Group National Crane Distributor network.
