Features and benefits

Efficient loading

Load capacity is 12, 14, 16 or 20 metric tons with several frame length options to meet your specific needs. Designed for smooth and precise operation, rugged cranes have excellent lifting torque, slewing torque and long reach.

Smooth and fast transport

Chassis and suspensions designed to confidently maneuver through even the most rugged forests when fully loaded. Komatsu Comfort Bogie axles with a high portal offset and V-shaped frames provide high ground clearance.

Operator comfort

Operator comfort is key to your productivity. Spacious and open, our cab provides fantastic visibility, ergonomic controls and a seat that delivers all-day comfort. Optional Comfort Ride suspension provides added comfort and capabilities.

Powerful yet fuel-efficient

High power, high torque and low fuel consumption engines deliver the performance you need. Maximize productivity with a sophisticated control system that automatically adapts to changes in engine load.

Intelligent hydrostatic transmission

Computerized HST system considers machine load, terrain conditions, power and torque output to give you exceptional tractive force. Hydraulic retarder overspeed protection on the 875-1 and 895-2 models ensures the driveline is not running too fast.

Machine and crane control

State-of-the-art MaxiXplorer/MaxiXT system monitors and controls everything from engine and crane to the transmission and service ladders. All operator-specific functions can be fine-tuned to achieve the sensitivity and speed each operator prefers.

Easy to maintain

Less time servicing means more time forwarding. Maintenance is quickly and easily completed with a service-friendly design featuring an electronically powered tilting hood. All filters are located together for easy access under the hood.

HD stacking blade

When you need to do ground or stump leveling on tough terrain, an optional heavy-duty stacking blade is available. Mounted with a high angle of departure for climbing obstacles, there’s no interference between blade, battery boxes or hood guard.

Options for added benefit

Multiple options are available to enhance your productivity and comfort including bunk wideners, rear and front view video cameras, computer touchscreen and electric fuel fill pump.
