Komatsu has recently jumped into the hydrostatic dozer market with their new D39 KomStat dozer. This dozer replaces the existing D39 torque converter dozer. The D39 KomStat weighs 20,000 lbs (9,100 kg) and has a 95 HP (71 Kw) engine.
Allied winch engineers worked closely with Komatsu engineering staff, both in the US and in Japan, to develop a dozer that could provide for a winch option. Komatsu elected to provide a power-take-off (PTO) shaft to the rear face of the dozer to power the Allied W3C winch. The PTO shaft will deliver close to full engine horsepower to the winch, for maximum line speed and pulling power. A hydraulic winch operated by an auxiliary circuit with limited horsepower was not considered adequate for this class of machine.
The W3C winch mounted on the D39 KomStat will provide for up to 49,000 lbs (22,300 kg) bare drum line pull. Maximum line speed is 90 ft/minute (27 m/minute) bare drum, and 157 ft/minute (48m/minute) full drum. This winch comes with the 61/1 gear ratio.
Allied offers PTO-driven winches for several brands of hydrostatic dozers, including Caterpillar, John Deere, and now Komatsu.
