Caterpillar has launched its new AD690 underground articulated truck.
With a payload capacity of 60 tonnes, it is now the largest model in Cat's UG truck range, and provides nearly 10% more in haulage over its previous AD55B.
It incorporates advanced heat shielding and cooling technology, as well as the Car C27 ACERT engine to provide a better ride.
The engine is rated at between 579 to 600kW has been refined for the AD60, and includes new pistons, high temperature fuel injectors, more durable rocker arm assemblies, ad redesigned crankshaft lubrication system, a high efficiency engine oil cooler, and a higher capacity fuel cooler.
The AD60 also comes with remote-mounted transmission oil coolers that ensure optimum operating temperature for the seven-speed Cat planetary powershift transmission, which features a lock-up torque converter for efficient, fuel-saving operation, as well as an electronically controlled retarding system for optimum safety and productivity.
According to Cat new features in the AD60 design include electronic integration of the engine and drive train, providing controlled-throttle shifting, overspeed protection, and body-up shift inhibitor.
The now standard Truck Payload Management System calculates payload data, and the VIMS Guardian System provides operators, service technicians and managers with machine health information to ensure high mechanical availability.
The choice of a dump or ejector body allows tailoring the AD60 to different applications, and the single-stage hoist cylinder speeds cycle times.
The frame design features box-section construction with materials and welding techniques that optimize structural life, and the articulation/oscillation hitch promotes stability and maneuverability in all types of ground conditions.
It weighs in at 110 tonnes.
