PERFORMANCE YOU CAN RELY ON
• The Series 900A is standard with 375°non-continuous rotation.
• Burst of speed winch provides faster winch payout and pickup of unloaded cable.
• The stronger standard torsion box improves rigidity, reduces truck frame flex and reduces the need for counterweight.
• A control knob located on the swing motor brake release valve can be easily adjusted to the crane operator's swing speed preference.
• Bearings on the boom and retract cables can be greased through access holes in the boom side plates.
• Number of internal boom parts has been reduced, deceasing service time when rebuilding the machine.
• Standard on the 900A, internal anti-two block wire routing eliminates the external reel and wire, removing the possibility of snagging reel or wire on obstructions and causing damage.
• Painting crane components before assembly reduces the possibility of rust, improves serviceability and enhances the appearance of the machine.
• A removable winch allows the internal telescoping cylinder to be removed quickly, without dismantling the boom.
• Speedy-reeve boom tip and sheave blocks simplify rigging changes by decreasing the time needed to change line reeving.
