1221E tops Case wheel loader line-up

THE Case 1221E, the largest model in the company’s E-series wheel loader range, will make its international show debut at Intermat, in Paris, from 20–25 April 2009. With an operating weight of just over 30 tonnes and a bucket capacity of 4.8–7.0 cu m, the loader is designed for a variety of quarry, extraction and general earthmoving duties.

The 1221E is powered by a Cummins QSM11 engine certified to EU Stage IIIA emissions standards. This offers 335hp (250kW) of power, backed up by 1,674Nm of torque at 1,400 rev/min. The engine benefits from a 40% torque rise, offering maximum rimpull when digging into a face.

This power output is transmitted through a torque-sensing autoshift transmission with four forward and three reverse gears. Both front and rear axles feature limited-slip differentials as standard, to provide maximum traction in all operating conditions.

 

To prolong component life and boost machine reliability, the service disc brakes are oil-cooled for maximum retardation and reduced heat build-up.

The E-series wheel loader cab is isolation mounted to reduce noise and vibration, and features a fully adjustable steering column, suspension seat, arm and wrist rests, and climate control air-conditioning as standard.

Pillarless glazing to the front and sides of the machine, combined with top-to-bottom glazing at the front of the loader, results in a high level of all-round visibility and a good view of the working area. Likewise, slim cab pillars to the rear of the machine promote safe operation in stocking operations and when loading around other machinery.

A combination of easy-to-read analogue gauges together with a digital display monitor provide comprehensive system information and a diagnostic port for technicians, while wide-opening double doors with removable lower panels allow easy ground-level access to filters and service points.

The machine features, as standard, a robust Z-bar loader linkage with twin bucket cylinders for high material retention and powerful breakout forces (24,759kg max at tilt cylinder), although an optional XR linkage is available for loading applications that require additional reach and dump height.

Selectable ride control provides smooth travel with increased load retention for load-and-carry operations, while an automatic mode engages ride control at speeds over 9.5km/h, when set, allowing the operator to focus on the machine and the site conditions for improved productivity and safer operation on site.
