KOMATSU PW170ES-6 CRAWLER EXCAVATOR

Technical Description

The Komatsu PW170ES-6 is a wheeled mobile excavator engineered for versatility and efficiency in material handling and earthmoving tasks. It offers four boom and stick configurations, with maximum cutting heights ranging from 29.3 ft to 30.2 ft, maximum digging depths from 15.8 ft to 18.8 ft, and maximum loading heights from 20.5 ft to 21.6 ft. The reach along the ground spans 26.5 ft to 28.8 ft, and vertical wall digging depths vary between 13.6 ft and 18 ft, allowing it to handle diverse excavation scenarios. The unit’s transport dimensions are compact for mobility, with shipping heights ranging from 10.4 ft to 11.1 ft and lengths of approximately 28.1 to 28.3 ft. Equipped with a turbocharged Komatsu SA4D102E-1 engine, the excavator delivers a gross power output of 124.8 hp (92 kW) at 2300 rpm from its 239.3 cu in, 4-cylinder diesel engine. Hydraulic operations utilize a variable displacement piston pump with a flow capacity of 79 gpm, feeding a hydraulic system with 35.7 gallons of fluid, governed by a relief valve pressure of 4623 psi. The fuel tank capacity is 66.1 gallons, supporting extended operation. The transmission is fully automatic with three forward and three reverse gears, enabling a maximum travel speed of 18.7 mph (29 kph). The swing mechanism rotates at 12 rpm, and the oscillating axle allows a 14-degree articulation for navigating uneven terrain. The excavator’s dimensions include a ground clearance of 1.2 ft, overall width of 8.1 ft, tail swing radius of 8.5 ft, and a wheelbase of 8.6 ft. The maximum bucket capacity is 1.5 cubic yards, facilitating substantial material movement. This machine balances power, reach, and mobility for demanding construction or utility applications.
