Commanding the top tier of the JCB lineup, the 457 is a formidable heavy-duty wheel loader built to conquer large-scale quarry extraction, bulk aggregate handling, and rigorous industrial applications. At the heart of this powerhouse is a premium Cummins B Series engine that generates a surging 257 net horsepower, delivering extreme low-end torque while remaining completely free of a diesel particulate filter (DPF). Tipping the scales with an operating weight of 44,090 lbs, the 457 establishes a massively stable footprint, giving operators the ultimate anchoring required to tear into heavily compacted material banks.

To drastically accelerate site output, this flagship loader is armed with a cavernous 4.6 yd³ standard bucket, ensuring maximum tonnage is moved with every single cycle. Even under the most punishing payloads, the machine remains firmly planted thanks to an extraordinary straight static tipping load of 35,867 lbs. When it comes to discharging the material, fleet operators will rely on the unit's 112.1-inch maximum dump clearance, which provides the precise height needed to easily clear the sideboards of heavy articulated haulers and elevated hoppers.
