Drive
Instrumentation
The instrument panel has logically grouped units, all within easy reach. Standard instrumentation includes warning lamps for battery charging, low engine lubrication oil pressure, low brake pressure, high coolant temperature, high gearbox oil temperature, and applied parking brake. In addition, gauges display values for engine coolant temperature, fuel quantity, and operating time.
Chassis
The chassis is built of fully welded steel profiles which gives a rigid construction with extremely strong mounting points for the drive axle and lift equipment. Stress concentrations have been eliminated for optimum tensile strength. The chassis is flexible and is used for a number of different drive line combinations. The space at the rear of the chassis is used for counter-weights, the number of which are adapted to the machine in question. The chassis has an extremely low profile for good visibility. The tanks are separately constructed and bolted to the chassis in a position that also contributes to good visibility.
Drive axle
The Kessler D81 drive axle is of an extremely robust design to be able to cope with tough working environments such as in the paper and pulp industries, saw mills, steel works, ports, and terminals. The axle has reduction in two stages - differential and hub reduction - which ensures a minimum of strain on the transmission system. The drive axle is fitted with a hydraulic braking system (see Service Brake System).
Service Brake System
The service brake system is of the Wet Disc Brake type, a system with oil-cooled discs that are alternately fixed to and rotating with the hub. When the brakes are applied, the discs are pressed together by hydraulic pressure from the brake pedal, which provides extremely effective braking. The system is virtually maintenance-free and can cope with heavy loads over an extended period of time, with no fade and without the need for brake adjustments. The heat generated during braking is dissipated via a cooling circuit in which the truck's total volume of hydraulic fluid comes into play. A special filter protects the braking system from any impurities.
Parking Brake System
The parking brake system consists of a dry disc brake on the in-going shaft of the drive axle. The disc brake is applied by means of a powerful spring in the parking brake cylinder and is released by means of hydraulic pressure from the parking brake valve in the cab.
Steering System
The steering system is completely hydraulic and is fed from hydraulic pump 1 (see the hydraulic system diagram), via a priority valve. When the steering wheel is turned, the steering valve transmits a load signal to the priority valve which ensures that the steering system always has sufficient hydraulic pressure. The steering axle is an extremely robust construction with a double-action cylinder. The pendulum suspension of the axle over powerful, spherical rubber bearings has a long operative lifespan and provides good shock absorption. The minimal number of parts ensures operational reliability, a minimum of service points, and easy maintenance. The steering geometry allows large wheel displacement and thereby, a tight turning circle.
