The 18 ton capacity 718 offers a rugged yet light truck compared to the competition, which brings benefits in terms of maneuverability and reduced ground damage. It has a high tip angle for effective material discharge and impressive tractive effort on heavy soft sites. A powerful engine results in a good power to weight ratio. Reliability & ease of use, along with an effective suspension enables the 718 to cope with demanding conditions.
The 718 is driven by a 5.9 liter Cummins engine producing 173 gross horsepower at 2200 rpm.This powerful engine allows the 718 to achieve top speeds of approximately 31 mph.The engine itself features low noise levels, improved efficiency and boasts high performance ensuring low operating costs while complying fully with North American off-highway emissions regulations.A Bosch in-line fuel pump provides optimum low speed torque and reduced smoke by precisely matching fuel/air mixture across the operational speed.An additional Wastegated Turbocharger provides higher cylinder injection pressures, resulting in cleaner combustion
Consistent with JCB's line of wheel loaders the ADT's feature a ZF Smooth-shift transmission that provides excellent performance with smooth gear changes reducing operator fatigue.The transmission provides 6 speed forward and 3 reverse gears with a choice of either automatic or manual operation interchangeable on the move. Either two or four wheel drive is available at the touch of a button.Super Max Trac limited slip differentials are fitted as standard which ensure optimum traction in even the softest conditions with no operator engagement required.To compliment the power provided by the engine and transmission, the 718 boasts a cast center articulation design with 45 degree turning and 360-degree oscillation, ensuring the cab always remains upright.Power assisted dual-braking system is used, with single caliper actuation per disc for safe and effective stopping. The calipers themselves are positioned to maximize their protection within the wheel rim.
The spacious operator's cab is center-mounted on the front frame of the machine to maximize all round visibility and stability. Visibility is further improved with the stylish sloping engine hood design.The cab itself is a Roll Over Protective Structure (ROPS) and Falling Object Protective Structure (FOPS)An air suspension seat, seat belt, extra training seat, tilt steering and air conditioning are all fitted as standard with a variety of options available to suit individual needs.The cab itself is isolated from the chassis by using four flexible mountings minimizing noise and vibration which in return reduces operator fatigue during long shifts making the machine all the more comfortable.
All switches, including body dump lever, gear selection, direction indicators, windshield wipers and heater controls are within easy reach of the operator and easy to use. The cab also features a 12v electrical socket.The JCB Electronic Monitoring System (EMS) monitors all vital functions and communicates information easily to the operator. In the event of a system failure, EMS shuts the machine down, protecting both the operator and the machine.An additional data logging facility enables functional performance to be registered for a comprehensive service record.EMS also has added safety benefits, allowing only first gear to be selected when the body of the machine is in the raised position.The 718 also features a suspension system which the EMS controls to ensure that the same ride height is maintained whether the machine is laden or unladen.The 722 also features a suspension system which the EMS controls to ensure that the same ride height is maintained whether the machine is loaded or unloaded
The 718 uses a simple twin gear pump design providing an effective hydraulic system that is uncomplicated yet economical. The main pump powers the steering and body dump, while the second pump powers both the braking system and suspension.The hydraulic tank is situated on the front of the machine with the filler located on the top of the tank for easy access.The rear chassis of the 718 Articulated Dump Truck is made from high tensile strength steel and has large box section reinforcements for rigidity and resistance to loading forces. Dumping is achieved via dual acting single-stage dump cylinders that are mounted within and protected by the rear frame.The body of the 718 is low and wide, providing a low center of gravity. This means it has a low load over height and a wider target for excavator or loader operators. The rear of the body has a 25-degree scow to retain material on steep haul roads. The improved 84-degree tip angle insures fast and complete material discharge even when dumping on an incline. With a 12.6 cu yd capacity, the 718 achieves a dumping time of 12.0 seconds, and a 8.0 second lowering time for quick cycles to increase productivity on the job.
