Feature Parameter

Castings Used in High Stress Areas

To increase frame reliability, steel castings have been incorporated at key frame pivot points and key load bearing critical portions of the frame. This includes the rear body pivot and horsecollar sections.

Electric Dynamic Retarder

The 4620 kW 6,196 HP retarding system provides stateof-the-art braking capacity for navigating today’s mining operations which contain steep continuous descents and sharp switchbacks.

Ergonomically designed cab

The Komatsu 960E-2 cab design provides a comfortable and productive environment to meet today’s mining demands. The cab includes tinted windows, heating and air conditioning, acoustical insulation, double sealed doors, and provides filtered and pressurized air.

Fully Hydraulic Controlled Multiple-Disc Wet Brakes

Although the dynamic retarding system is the primary braking force, the 960E-2 comes standard with four-wheel, hydraulically actuated, oil cooled service brakes. In the event that the truck’s hydraulic system pressure drops below an acceptable level, accumulator tanks will automatically apply all wheel brakes to bring the truck to a complete stop.

Hill Start

An innovative feature the Komatsu drive system provides is the Hill Start logic. This built in functionality will help reduce rollback in the event of a stop while the truck is ascending a ramp. Additionally, the feature automatically controls the braking function when an operator that is stopped on grade wants to continue up the ramp.

Hydropneumatic suspension

Hydrair II^® is a suspension system that utilizes four nitrogen-over-oil cylinders. This suspension system is designed to maximize machine productivity by providing the operator with a smooth and comfortable ride. By absorbing shocks to the chassis during operation, Hydrair II^® contributes to the durability of the machine’s frame and components.

Komatsu AC Drive

Our Komatsu AC drive is designed to provide the reliability and highest quality from Komatsu. Held to the highest standards, the transmission was subjected to extensive testing and quality confirmation, both on the bench and in the field. A full scale bench durability test was conducted during development to evaluate design quality prior to production. By using planetary design, extensive machining is not required during a standard rebuild.

Komatsu Drive

Field tested in the toughest applications, Komatsu Drive is a unique system that features:

Komatsu SSDA18V170 High Horsepower Engine

Komatsu’s SSDA18V170 engine was designed and developed by Industrial Power Alliance (IPA) technical joint venture between Komatsu and Cummins®. This 2610 kW 3,500 HP engine will operate in most of today’s mining applications without experiencing power derate. Fuel efficiency is maximized due to optimized air handling with two-stage turbocharging. A standard pre-lube system is designed to eliminate start-up wear and increase overhaul life.

Propulsion/Retard Speed Control

Propulsion/Retard Speed Control allows the operator to set a desired speed. This function monitors the speed of each wheel independently for immediate adjustments in propulsion or retarding effort in order to maintain the desired speed.

Structurally Enhanced Frame Design

By using advanced computer-aided design, finite element analysis, and full-scale dynamic and static testing, the frame has been designed to carry 327 tonne 360 short tons and provides the highest structural reliability from Komatsu.

Tight Turning Radius

By using double acting hydraulic steering cylinders with a six-point articulation linkage, the 960E-2K power steering system provides steering control with minimal operator effort. The turning radius of the 960E-2K is 16 m 52' 6", which provides excellent maneuverability for tight loading and dumping conditions. The steering accumulators comply with ISO-5010 standards.

Traction (Spin-Slide) Control

During slippery conditions, the 960E-2K wheel traction control technology detects and corrects wheel spin or slide events. Traction Control operates automatically and independently of the service brakes, providing a means of controlling the machine in slippery conditions.

Body

All-welded steel flat floor body with horizontal bolsters and full canopy. Rubber mounts on frame are standard. Eyebrow, body up sling, extended canopy and pivot exhaust heating are optional.
