CASE 921E WHEEL LOADER

Technical Description

The Case 921E is a robust wheel loader designed for heavy-duty construction and material handling tasks. It features a Cummins QSM 11 Tier III Certified turbocharged engine with aftercooler, delivering 274 hp (204 kW) gross and 297 hp (221 kW) net power at 1800 rpm, with six cylinders generating peak torque at 900 rpm. The loader has an operating weight of 50,622 lbs (22,962 kg) and a wheelbase of 11.2 ft (3 m). It offers a rated bucket capacity of approximately 5.78 cubic yards (4 m³) heaped, with a breakout force of 44,476 lbs (20,174 kg), and bucket width of 10.4 ft (3 m). The bucket's dump clearance at max raise is 10.1 ft (3 m), with a maximum hinge pin height of 14.1 ft (4 m) and a reach of 4.2 ft (1.3 m) at max lift and dump. The hydraulic system comprises a closed-center, pressure/flow compensated pump with a flow capacity of 42.8 gal/min (159 l/min) and is designed for efficient load handling with raise time of 6.2 seconds, dump time of 3.6 seconds, and lower time of 3 seconds. Operating pressure is set by a relief valve at 3600 psi. The 4-speed forward and 3-speed reverse transmission with electronic control module enables max speeds of 23.2 mph forward and 16.1 mph reverse. The loader rides on 26.5 x 25 L3 bias tires, supporting rear axle oscillation of 24°. Key fluid capacities include 104 gal fuel, 64 gal hydraulic fluid, and 15 gal coolant. Dimensions include a height to cab top of 12.2 ft (4 m), and width over tires of 9.8 ft (3 m), with a turning radius of 22.6 ft (7 m). This combination makes the Case 921E a powerful, versatile machine for rigorous loading operations.
