JCB 507-42 Specifications
The JCB 507-42 Loadall is a mid-size telescopic handler
designed to deliver a balance of compact dimensions, strong lift capacity, and
extended reach for construction, industrial material handling, agricultural
support, and rental fleet applications.
Positioned between the 506-36 and 509-42
models, the 507-42 provides increased lift height and reach over compact
machines while retaining excellent maneuverability and predictable
handling characteristics. With a maximum rated lift capacity of 7,000 lb
(3,176 kg), a maximum lift height of 42 ft (12.8 m), and a maximum
forward reach of 28 ft (8.53 m), the 507-42 is well suited for placing
palletized materials, structural components, and equipment at height.
The machine incorporates JCB’s proven Dieselmax
turbocharged engine, a heavy-duty powershift transmission, permanent
four-wheel drive, and robust epicyclic axles. Automatic Rear Axle
Stabilization (RAS), a reinforced high-tensile steel boom, and a
high-capacity hydraulic system ensure stability and precise load control
across a wide operating envelope. Designed to comply with ASME B56.6
standards, the 507-42 emphasizes safety, durability, serviceability, and
long-term reliability.
The JCB 507-42 is powered by the JCB Dieselmax
4.4-liter turbocharged industrial diesel engine, engineered to deliver strong
low-speed torque, fuel efficiency, and durability in demanding duty cycles.
