Wheeled Loader Boosts Fuel Savings and Power
JCB’s new 457 wheeled loader increases power by 16% and delivers a fuel savings of up to 6% from the previous model. Replacing the 456, the heart of the 457 is a Tier 4 Interim complaint 8.9-liter Cummins engine – the biggest engine in JCB’s construction equipment range.
The engine incorporates the following technology:
- A high-pressure common rail fuel injection system
- Exhaust gas recirculation
- A diesel oxidation catalyst, plus a diesel particulate filter
- A variable geometry turbocharger, which delivers an improved machine response at lower rpm
The JCB 457 delivers 250 hp. and doesn’t require any supplementary additives to provide high power outputs with low emissions. A new economy mode reduces engine output for lighter duties. The machine also boasts a low idle feature and an engine shutdown mode, which kicks in after a pre-determined idle period to save fuel.
A four-speed automatic power shift transmission comes as standard and a five-speed power shift transmission is also available. The new ZF automatic differential lock axle option means that customers can choose from standard open differential, limited slip differential, or an automatic differential lock on the front axle only.
The JCB 457 also offers more loading capacity, weighing 683 pounds more than the 456. The tipping load is increased by 3.3%, which means that an extra quarter of a ton can be carried in the bucket.
Other improvements include:
- The ability to adjust the JCB Smooth Ride System so it can be activated at any speed, allowing operators to tailor it to individual site requirements.
- Relocation of the hydraulic tank from beneath the cab steps to behind the cab, reducing the potential for damage or contamination.
Starting price for the JCB 457 wheeled loader is $288,000.
