2007-2012 CASE 1221E XR WHEEL LOADER

Technical Description

The CASE 1221E XR wheel loader is a high-performance, 30-metric-ton machine engineered for demanding applications in sand and gravel, stone, aggregates, roads, bridges, and site preparation. Powered by a fully electronic, six-cylinder Cummins QSM11 Tier 3 engine, it delivers 320 net horsepower at 2,200 rpm and 1,235 lb-ft of torque at 1,400 rpm, with a 40% torque rise for enhanced productivity. The loader features a robust XR (high lift) linkage configuration, providing increased dump clearance—up to 12.4 ft at maximum raise—ideal for loading into high-sided trucks. The bucket offers a heaped capacity of 5.7 cu yds (4 m³) and a struck capacity of 6.7 cu yds (5 m³), with a width of 11.4 ft (3 m). The hydraulic system delivers a pump flow of 127.4 gal/min (481 l/min) and relief valve setting of 2,990 psi, enabling fast cycle times: 6.4 seconds to raise, 3 seconds to lower, and 1.4 seconds to dump. The machine has a 24V electrical system, 70-amp alternator, and a 124.2-gal (469 l) fuel tank. It features limited-slip axles on both front and rear for superior traction, outboard planetary wet-disc brakes for stability, and a large, isolation-mounted cab with a 72-dBA operator sound level. Standard single-lever joystick loader control and optional Ride Control (full-time or auto mode) enhance operator comfort and material retention. The 1221E XR has a 4-speed forward, 3-speed reverse transmission, with a maximum forward speed of 21.1 mph (34 kph) and reverse speed of 14.7 mph (23 kph). Its operating weight is 67,020 lbs (30,400 kg), with a static tipping weight of 48,060 lbs (21,800 kg).
