• Choice of hook speeds for raising and lowering facilitates stringing, cradling and lowering in.
Big lifting capacity
• Komatsu pipelayers have the largest lifting capacity in their respective classes.
• Adjustment of the counterweights is made hydraulically and conveniently by a lever beside the operator's seat for machine balance.
Safe operation
• Komatsu pipelayers offer safety features to keep operators working confidently.
• All machines are standardly equipped with an automatic boom maximum stopper device.
• There is a free-fall setting on the hook control lever for use during an emergency.
• Komatsu pipelayers have a closed-type winch brake that prevents slips during operation in wet weather.
• Because the hook wires are located away from the operator, danger in the event of a wire cut is minimized.
Proven, stable undercarriage
• Main components of these three machines are basically the same as those of the Komatsu D355A, D155A and D85A bulldozers. They have a proven record for reliable and durable performance, plus easy maintenance.
• A wide track gauge, large length of track on ground and counterweights give these pipelayers more stability to operate on steep slopes .
