JCB 722 Articulated Dump Truck
The 22 Ton capacity 722 is the largest model in the JCB range of ADT's. With more power and its ability to carry more payload than its lighter family members, the 722 has all the key features that are expected of this size of machine. With the JCB patented front suspension, similar to that used on the 718, the 722 gives an extremely comfortable ride whether laden or not, ensuring fast cycle times whatever the ground conditions. It's the perfect machine for rental companies, contractors, house builders, landfill sites, quarries, sandpits, forestry and many more.
The 722 is driven by a 6.7 liter QSB Cummins engine producing 270 gross hp at 2400 rpm allowing top speeds of 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 and European 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. JCB's ADT range features a ZF Smooth-shift transmission that provides excellent performance with smooth gear changes which help reduce operator fatigue. The transmission provides 6 forward and 3 reverse gears with a choice of either automatic or manual operation interchangeable on route. Constant 6 wheel drive, with longitudinal lock up of all axles at the touch of a button. Super Max Trac limited slip differentials are fitted as standard which automatically engage to maximize traction in even the softest conditions. To compliment the power provided by the engine and transmission, the 722 boasts a cast center articulation design with 360-degree oscillation, ensuring the cab always remains vertical. A power assisted dual-braking system is used, with single caliper actuation per disc for safe and effective retardation. The calipers themselves are positioned on the hub to maximize their protection. The spacious operator's cab is center-mounted on the front frame of the machine giving good all round visibility and stability. Visibility is further improved with the sloping engine hood design. The cab itself is Roll Over Protective Structure (ROPS) and Falling Object Protective Structure (FOPS) approved for operator safety.
