The JCB 457 HT SHL wheel loader is a high-performance, heavy-duty machine designed for demanding loading applications. It features a powerful MTU 6R1000 turbocharged six-cylinder engine delivering 258 hp (192 kW) gross power at 1600 rpm, compliant with EPA Tier 4 Final emissions standards. The hydraulic system operates at 220 bar pressure with a variable displacement pump flow of 40.5 gallons per minute (151 L/min), enabling fast cycle times: 1.2 seconds for dump, 4.1 seconds down, and 5.8 seconds raise, totaling 11.1 seconds per hydraulic cycle. The 3.7 cu yd (heaped) bucket has a breakout force of 39,342 lbs (17,845 kg) and a width of 9.4 ft (3 m), providing robust material handling capacity. Dimensionally, the loader measures 31.1 ft (9 m) in length with the bucket on the ground, 11.3 ft (3 m) in height to the top of the cab, and has a wheelbase of 10.9 ft (3 m). It offers a max hinge pin height of 17.3 ft (5 m) and a dump clearance at max raise of 13 ft (4 m). The machine’s operating weight is approximately 47,274 lbs (21,443 kg), with a payload capacity of 9,932 lbs (4,505 kg) and a full turn tipping load of 19,862 lbs (9,009 kg). It uses a 4-speed non-lockup torque converter transmission for max speeds of 22.5 mph forward and 14.7 mph reverse, coupled with 40° articulation and a turning radius of 23.4 ft (7 m). The unit includes a 24V electrical system, heavy-duty mechanical components, and fluid capacities optimized for operation, supporting high productivity and durability on challenging job sites.
