    Ÿ TRACTION CONTROL SYSTEM (TCS)

    Electronically monitors and controls rear wheel slippage for greater traction and enhanced truck performance in poor underfoot conditions. If slippage exceeds a set limit, the oil-cooled disc brakes engage to slow the spinning wheel. Torque is then automatically transferred to the wheel with better traction.

    Ÿ DIFFERENTIAL ACTION

    Normal differential action provides superior maneuvering and control in slippery conditions.

    Ÿ INTEGRATED BRAKING CONTROL (IBC)

    Combines Hydraulic Automatic Retarder Control (HARC) and Traction Control System (TCS) into one integrated brake control system for optimum efficiency, performance and reliability.

    Ÿ FUEL EFFICIENCY

    The engine provides additional retarding by running against compression on downhill hauls. During retarding applications the engine ECM does not inject fuel into the cylinders for exceptional fuel economy.

    The left side mirror mounting bracket is more robust and allows mirror glass to be easily replaced, without the need for a new mirror assembly. New mirror glass slides in and out of the carrier, reducing downtime and maintenance costs.

    SAFETY

    Caterpillar mining machines and systems are designed with safety as the first priority.

    PRODUCT SAFETY

    Caterpillar has been and continues to be proactive in developing mining machines that meet or exceed safety standards. Safety is an integral part of all machine and systems designs.

    SAE AND ISO STANDARDS

    The 793D is designed to many national and international standards.

    INTEGRAL ROPS CAB

    Resiliently mounted to the main frame to reduce vibration and sound, the integral ROPS structure is designed as an extension of the truck frame. The ROPS/FOPS structure provides “”five sided protection”” for the operator.

    LADDER/SECONDARY EGRESS

    A wide, stationary stairway allows easy access to and from the machine. The ladder on the left side of the machine permits secondary access or emergency egress.

    BRAKE SYSTEMS

    Four corner oil-cooled braking system provides excellent control in slippery conditions. The service brakes and retarding system are actuated by modulated hydraulic pressure, while secondary and parking brake functions are spring applied and hydraulic released. This system assures braking in the event of complete hydraulic failure.

    STEERING SYSTEM

    A twin double-acting cylinder steering system is designed to deliver precise control under all loading and underfoot conditions. The steering hydraulic system is separate from the main hydraulic system to prevent cross-contamination and overheating from other sources.

    ENGINE SHUTOFF SWITCH

    A secondary engine shutoff switch is located at ground level.

    ELECTRICAL SYSTEM DISCONNECT

    A battery disconnect switch, located directly above the front bumper provides ground level lockout of the electrical system.

    OVERLOAD POLICY

    Safety is integral to maintaining the highest productivity in mining machine operation. The Caterpillar 10/10/20 Overload Policy assures that steering and braking systems have sufficient capacity to perform, even at 20% overload.
