a quality Process We know that a wheeled loading shovel is a key part of the on-site process. That’s why the JCB 457 is built ON a foundation of quality and reliability. The processes we’ve used to design and manufacture the 457 will safeguard your working process, hour after hour, day after day. We use state-of-the-art manufacturing processes like robot machining, precision paint technology and innovative assembly techniques to achieve the very highest levels of quality. Finite element analysis and rig testing ensure superior structural strength and durability. Cold cell testing guarantees...

The articulation joint has a heavy-duty centre pin and oversized bush, as well as twin taper roller bearings on the bottom box joints. This can tolerate both vertical and horizontal loadings for durability and rigidity. Well articulated 4 The 457’s articulation joint has a heavy-duty box section – much stronger than a single plate with a boss. Steering rams are positioned high up and well protected from possible impact and site damage. 5 Hoses are neatly routed and clamped through the 457’s articulation joint, well away from any pinch points.

PRODUCTIVE PERFORMANCE The JCB 457 can perform great feats of productivity. With high breakout forces, it’s bucketloads more powerful than its competitors and our new rear chassis Layout provides 3.3% extra lift capacity than the previous model. POWER 200 The Cummins QSL 8.9 litre engine achieves high power (186kW, a 16% increase) and peak torque (1085NM, an 18% increase) at low revs for excellent response. The engine is Tier 4i/Stage 3b emissions compliant, using an exhaust aftertreatment system with particulate filter and oxidation catalyst. Engine productivity 1 A variable geometry...

PRODUCTIVE pERFORMANCE Loading productivity (continued) Drivetrain productivity You can choose your ideal loader arm on a 457, with z-bar linkage (ZX) for high breakout applications or high torque (HT) for parallel lift and multiattachment use. 5 Choose a ZX high lift or HT super high lift option and you can use a 457 for higher loading height applications (hopper and lorry loading). The 457’s optional 5-speed transmission with torque convertor lock-up provides closer ratios for better acceleration, hill climbing and roading performance. The lock-up element eliminates losses from the torque...

EFFICIENT BY DESIGN The JCB 457 is designed to move more material for less. To achieve this, we’ve designed the engine, axles, driveline and hydraulics to work in harmony with each other, for ultimate efficiency. Our engine idle shutdown safely applies the brakes and turns the 457 off after a programmable amount of time. Automatic idle returns the 457’s engine to 700rpm after 30 secs of inactivity. 2 The 457’s Eco mode limits engine speed to 1800rpm and reduces power to 217hp for reduced fuel consumption. Productivity remains formidable. An efficient driveline 3 Our torque lock-up 5 speed...

An efficient hydraulic system 5 A hydraulic cooling fan automatically reacts to ambient temperature and adjusts the 457’s fan speed to optimise cooling and reduce fuel consumption. This also lowers noise. 6 Unloaded spool valves in the valve block mean that arms lower under gravitational, not hydraulic force, reducing fuel consumption. JCB’s innovative variable displacement pumps feed a load-sensing valve block which only consumes power on demand, providing precise, efficient loader control. 457 WHEELED LOADING SHOVEL

COMFORTABLY SUPERIOR Keeping operators fresh and alert all day long results in increased safety and productivity. With that in mind, the 457’s 3m³ cab is roomy, easy to access, and quiet. It also has excellent visibility and intuitive to use ergonomic controls. In control 1 A tilting and telescopic steering column provides easy adjustment for maximum comfort. 2 A range of loader controls; multi-lever, joystick, or joystick with proportional auxiliary controls. 3 A stylish, modern central dash display combines analogue dials and a colour LCD screen – this can display machine health details,...

COMFORTABLY SUPERIOR Exterior comforts 4 The 457 has air conditioning and automatic climate control options to create perfect working temperatures. 5 3 or 4 spool hydraulics and a quickhitch enable many attachments to be used easily for extra versatility. Internal noise is just 70dbA. The 457’s selectable loader arm detents mean operators can set loader arm height limitations, return to dig and float functions for improved safety and productivity. 7 JCB Smoothride load suspension limits shock loadings and therefore reduces material spillage and structural stress, as well as increasing...

LOW MAINTENANCE LONG INTERVALS A wheeled loading shovel needs to spend the maximum amount of time hard at work. We’ve designed the 457 to do just that, with LONG service intervals and quality components. Access all areas 1 Gain access to the engine bay and cooling pack areas easily with wide-opening gullwing doors. 2 The 457 has a large single faced cooling package for unrivalled quick, easy and safe cleaning 3 Ground level daily check and grease point access makes life easier and safer. Looking after itself 4 A 457’s electronic monitoring system relays machine condition giving real time...

LOW MAINTENANCE LONG INTERVALS By using top components in the 457 (Cummins engine, ZF transmissions and axles, Rexroth pumps and Parker valve blocks), we’ve built in long service life as standard. 8 Full hydraulic dual circuit braking with multiple oil immersed disks gives the 457’s braking system a virtually maintenance-free lifespan. 9 Check brake, steering and hydraulic system pressures easily on a 457 with group test ports. 457 WHEELED LOADING SHOVEL
