JCB has introduced a new Wastemaster wheeled loader, the 22 tonne 457WM, which is the largest in the range. Power comes from a 7.7 litre MTU Tier 4 Final/Stage IV compliant diesel delivering 193 kW (258 hp), up from 186 kW (250 hp) on the previous machine despite having a smaller capacity. According to the company the engine delivers this increased power at lower rated engine revolutions, reducing fuel consumption, noise and emissions. JCB has also fine-tuned the match between the engine, the torque converter and transmission to match it with both the standard four speed and optional five speed transmissions. JCB claims a fuel efficiency gain of up to 16% as a result.

The 457WM is the first to use the company’s next generation JCB CommandPlus cab. JCB has focussed on providing the best in cab comfort. The totally new ROPS structure has A pillars that have been moved out to the same width as the rear of the cab, providing a larger interior with a panoramic front windscreen. The machine features JCB’s Command Driving Position, with revised pedals, a new adjustable steering column and seat-mounted hydraulic controls.

All switches and auxiliary controls have been repositioned on the right hand A pillar, providing the operator with a simplified interior and easy access to all machine controls. The 457WM has two full colour LCD screens, one in the central console and a second at the top of the right hand A pillar. This second screen incorporates access to the loader’s operating menus and acts as a monitor for the machine’s rear view camera.

According to JCB, the most visible change to the 457WM, aside from the new cab, is the adoption of a sloping one-piece engine canopy. This engine cover can be electrically raised away from the cab to provide improved access to the engine and drivetrain for regular maintenance. The rear section can also be hinged away from the machine to provide access to the cooling pack, which now features a swing-out hydraulically-driven, on-demand cooling fan situated at the rear of the machine.
