Features
Durable Wet Disc Brakes
The wet disc brake system is sealed with oil to block dust penetration, providing durable, water resistant and fade resistant characteristics.
The oil in a wet disc brake system is circulated through the brake oil cooler. This mechanism ensures stable braking under a heavy workload and prevents deterioration of the braking force that could be caused by raised oil temperatures.
Greatly Reduced Total Operating Costs
The standard sealed wet disc brake system is designed to withstand 10,000 hours of operation without maintenance, thereby eliminating downtime and the added maintenance costs of frequent brake shoe replacement. The engine oil replacement interval has been extended to 500 hours reducing oil costs.
Reliable Hydraulic and Electrical Systems
The main hydraulic pipe connectors are face-sealed using O-rings. Waterproof connectors are provided to the main harnesses and the system controller in order to provide higher resistance to water and dust. Hydraulic and electrical piping systems are in separate configurations to improve the reliability and servicing.
First Class Cycle Time
The combination of a technologically advanced, compact 3.3-liter engine and advanced OLMS hydraulic system achieves high productivity and first class cycle times.
OLMS Hydraulic System
The OLMS Hydraulic System contributes to lower fuel consumption. As engine speeds change, the engine RPM sensing control pump detects engine revs and then controls the oil feed to reduce the load on the engine. This unique hydraulic system offers optimized balance of traveling and loading work while delivering increased hydraulic efficiencies in the most demanding applications.
Fully Hydrostatic Power Steering
The Fully Hydrostatic Power Steering (FHPS) system facilitates fully stationary steering as well as switchback operations using the small diameter steering wheel. The system has a superior response capability so that the operator can maneuver easily with a load even in a tight area
KOPS Plus Komatsu Operator Presence System
KOPS Plus locks out lift, lower, tilt and traveling functions when the operator leaves the seat for more than three seconds. They do not resume until the operator returns to the seat and resets the controls. A flashing yellow warning light alerts the operator when the KOPS lock is activated. In addition, the forks cannot be lowered while the key is in the off position.
