There really are loads of reasons to choose the JCB 457 ZX wheel loader. For starters, it’s productive, efficient, easy to maintain and extremely durable. The 8.9-liter 6-cylinder Cummins QSL engine is Stage 3b / Tier 4 compliant. It helps the 457 ZX wheel loader to produce 16% more power – 250-horsepower (186 kW) – and 18% more torque – 9,603 foot pounds (1,085 Nm) than the previous 456 model. Of course all JCB front end loaders boast cutting edge technology to boost efficiency still further. On the 457 ZX, there’s an intelligent clutch cut-off feature that gives maximum hydraulic performance and limits vehicle speed when loading. There’s also automatic idle shutdown, load-sensing hydraulics and a variable speed fan. The JCB 457 ZX wheel loader also combines comfort, safety and serviceability to make it the perfect all-round package.

Power and Productivity
The JCB 457ZX wheel loader has power and productivity by the bucketload. The 250 hp (186 kW) Cummins engine is mated to a 4-speed ZF fully automatic powershift transmission for stepless gear changes and smooth operation. What’s more, with 3 axle options, including open differentials, limited slip differentials and automatic locking differentials, a 457ZX will always help you keep a grip on productivity.

At the business end of the 457 X wheel loader, ZX loader geometry generates 38,667 ft. lbs. (172 kN) breakout force. Besides huge breakout forces, the Z-linkage loader design means this front loader is also capable of high dump angles for improved productivity. A revised rear chassis design provides 3.3% extra lift capacity over the outgoing 456ZX.

Design Innovation
For the ultimate in precise, efficient loader control, the JCB 457ZX wheel loader’s innovative variable displacement pumps feed a load-sensing valve block, only consuming power on demand. They can also provide 326 l/m hydraulic flow for maximum multi-functioning performance.

Meanwhile our Smoothride suspension system reduces shock loadings and aids material retention.

Clever electronic management on the 457ZX wheel loader can control progressive clutch cut-off for efficient, productive loader control. This feature automatically diverts maximum power to the loader hydraulics for optimal truck / hopper loading duties.

On the drivetrain, the 457ZX has unloaded spool valves, meaning the loader arms lower under gravitational, not hydraulic, force. Meanwhile, wheel speed braking means 457ZX brakes rotate at the same speed as the wheels for heat and drag reduction, as well as improved fuel economy.

Controllability
The JCB 457ZX wheel loader uses a range of cutting edge operator aids to maximize efficiency.

Operating 457ZX front end loaders is simple and efficient. Operators can choose the loader controls they prefer: multi lever, joystick, proportional auxiliary controls. Return-to-dig, arm height limitation and float functions are always at hand. Disabling those aids is possible with just the flick of a switch. Like other wheeled loaders in our range, the 457ZX uses innovative load-sensing hydraulics for precise and efficient control.

Visibility is excellent all-round on this wheel loader thanks to a 3-piece laminated front screen, heated exterior mirrors and a sloping rear hood design.

Serviceability and Durability
When you buy a wheel loader, you need to know it’ll be easy to maintain, reliable and long-lasting. That’s why we’ve built 457ZX wheel loaders using only the best possible components, and designed it to maximize uptime.

457ZX wheel loader has class-leading service and maintenance access, with gull-wing doors providing easy access to the engine bay and cooling pack areas.

The whole of the 457ZX wheel loader went through an extensive development program to ensure its durability. For starters, we tested across 1.2 million cycles and used computer-aided finite element structural analysis. Then, because our front end loaders are used in every corner of the globe, we field tested the 457ZX in climates ranging from -4°F to 122°F (-20°C to 50°C).

Further Peace of Mind
Large diameter loader and articulation pins and bushes have secondary seals, blocking dirt.

Electronic Management System controls tractive effort via the transmission to reduce service brake wear and fuel consumption
