2006 - 2007 JCB 426ZX WHEEL LOADER

Technical Description

The JCB 426ZX wheel loader is a versatile machine offering a breakout force of 32,570 lbs (14,774 kg) and a heaped bucket capacity of 2.5 cubic yards (2 m³), with a struck capacity of 2.2 cubic yards (2 m³). The bucket width measures 8.4 ft (2 m), optimized for efficient loading and material handling. Its maximum dump clearance at full lift is 9.8 ft (3 m), with a max lift height reaching 12.2 ft (4 m), supported by a powerful turbocharged, wastegated QB6.7 engine delivering 165 hp (123 kW) gross power and a maximum torque of 540 lb-ft at 1400 rpm. The engine’s six-cylinder configuration runs at 2200 rpm for power measurement, ensuring high efficiency and performance. Hydraulics are managed by twin variable displacement piston pumps with a load-sensing system, capable of 69.8 gal/min (261 L/min) flow, enabling fast dump time of 1.3 seconds, raise time of 4.4 seconds, and lower time of 2.7 seconds under a relief valve setting of 3625 psi. The 426ZX features a smooth-shift ZF 4WG 160 powershift transmission with 4 forward and 3 reverse gears, enabling a max forward speed of 23.5 mph (37.8 kph) and reverse speed of 15.6 mph (24 kph). Operating weight is 29,167 lbs (13,230 kg) with a wheelbase of 9.9 ft (3 m), tire size of 20.5R25 XHA (L3), and a turning radius of 19 ft (6 m), making it maneuverable in various terrain. The loader’s ground clearance is 1.5 ft (0.46 m), and its overall height to cab top is 10.9 ft (3 m). The machine is designed for durability, productivity, and efficient fuel usage with a 24 V electrical system and a 70 A alternator, suited for heavy-duty applications in construction and material handling.
