JCB’s all-powerful 457 wheeled loader
JCB has unveiled its powerful 457 wheeled loader at Conexpo 2014
JCB’s new power-packed 457 wheeled loader is the first of the UK manufacturer’s machines to show off the new JCB CommandPlus cab, said to offer operators the ultimate in comfort.
The cabin’s 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 also features JCB’s Command Driving Position, with revised pedals, a new adjustable steering column and seat-mounted hydraulic controls.
JCB’s largest wheeled loader, the new 457 features a 7.7litre MTU Tier 4 Final engine, delivering 193kW, up from 186kW on the previous machine, and contributes a massive fuel saving of around 16% compared to the previous model. As with other JCB machines, the engine in the 457 meets Tier 4 Final without the need for a costly diesel particulate filter (DPF).
Aside from the new cab, the most visible change to the 457 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.
Speaking at Conexpo 2014 about JCB’s extensive new machine range, Tim Burnhope, the company’s chief innovation and growth officer, said, “After extensive consultation with both customers and operators, we are unveiling a new design direction. We aim to set ourselves apart from the competition; not just in how our machines look, but how they operate, and how they perform.”
