Forwarder

845-1

  • Gross load capacity 12 000 kg 26,455 lbs.
  • Horsepower 140 kW @ 1 900 rpm 188 HP @ 1,900 rpm
  • Tractive force 170 kN 38,218 lbf.

Productivity and efficiency

Drive high productivity for thinning and light clear-cutting with this 12-metric-ton class of the 845-1 forwarder. You’ll appreciate the remarkable maneuverability and excellent fuel efficiency. Hydraulic retarder overspeed protection ensures the driveline won't run too fast.

  • Choose the right machine for the job with four load-capacity options
  • Drive high productivity with powerful cranes and rugged FlexBunks
  • Tackle the roughest terrain with powerful hydrostatic transmission and high ground clearance

Features and benefits

Efficient loading

Match the machine to the job with a variety of load capacities — 12, 14, 16 or 20 metric tons — and several frame-length options. Designed for smooth and precise operation. Rugged cranes have a long reach and excellent lifting and slewing torque.

Smooth, fast transport

Maneuver with confidence in the most rugged forests, even when fully loaded. Chassis and suspensions are designed for performance under demanding conditions. Komatsu Comfort Bogie axles with a high portal offset and V-shaped frames provide some of the highest ground clearance in the industry.

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 efficient

Maximize performance with high power and torque while driving efficiency with a fuel-efficient engine. A sophisticated control system automatically adapts to changes in engine load.

Technology-driven traction

Get exceptional tractive force thanks to an intelligent hydrostatic transmission system that considers machine load, terrain conditions, power and torque output. Hydraulic retarder overspeed protection on the 875-1 and 895-2 models ensures the driveline won't run too fast.

Customize your controls

Give operators the benefit of machine controls they can fine-tune for sensitivity and speed or smoothness and accuracy – whatever the job demands. Our state-of-the-art MaxiXplorer/MaxiXT system monitors and controls everything from engine and crane to the transmission and service ladders.

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.

Overcome climbing obstacles

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.

Cold weather starting

Don’t lose valuable time when the temperatures drop. A standard diesel heater system heats the engine coolant, hydraulic oil and the batteries to facilitate cold-weather starting on the 845-1, 855-3, 875-1 and 895-2.
