Powered by an electronically controlled Tier-3-certified engine, Case CE’s new 30-t (33-ton) articulating wheel loader features easy maintainability and a spacious, isolated cab designed to maximize operator comfort and productivity.

Case Construction Equipment announced at ConExpo 2008 the expansion of its E Series wheel loader line with the addition of the 1221E articulating wheel loader. The new wheel loader features an electronically controlled U.S. EPA Tier-3-certified engine, a spacious cab designed for operator comfort and visibility, and streamlined maintenance.

Designed for sand and gravel, stone and aggregates, roads and bridges, and site-preparation applications, the Case 1221E wheel loader has an operating weight of 30 t (33 ton) and a standard payload capacity of 7.6 yd3 (5.8 m3). It delivers a lift capacity of 13.07 t (14.41 ton) at full height.

The new wheel loader is powered by a fully electronic, six-cylinder, Tier-3-certified Cummins QSM 11 engine that delivers 320 net hp (239 kW) at 2000 rpm and 1235 lb·ft (1674 N·m) at 1400 rpm. The turbocharged, 10.8-L engine features electronic common-rail fuel injection to optimize power delivery and fuel economy. Power is delivered from the engine by a 4F/3R proportional transmission with electronic control module.

Limited-slip axles on the front and rear automatically transfer power from the wheel that’s slipping to the wheel that’s gripping, to provide dependable traction and high operability through a wide range of ground conditions. Outboard planetary and wet-disc brakes also contribute to machine stability.

Traditional Z-bar and XR linkage configurations are available for the 1221E. Z-bar linkage facilitates high production, fast cycles, optimized operating loads, and high visibility to the bucket. For applications requiring more dump clearance, such as loading materials into high-sided trucks, the 1221E XR has high lift throughout the complete cycle.

“For increased productivity in quarry and aggregate, and roads and bridges applications, you won’t find a more productive wheel loader than the 1221E,” said Dave Wolf, Brand Marketing Manager, Case Construction Equipment. “For site preparation and forestry, this heavy-duty machine can hold up under the toughest conditions.”

The 1221E wheel loader’s large, isolation-mounted cab provides an operator sound level of 72 dB(a), one of the quietest operator environments in the industry, according to the company. A range of operator features helps to increase operator comfort, productivity, and visibility, including a tilt and telescoping steering column, infinitely adjustable seat, and adjustable armrests and control placement. Floor-to-ceiling glass in the front and a sloped rear engine compartment combine to give the operator good visibility both forward and to the rear.

Easy-to-reach controls include the standard single-lever joystick loader control with forward-neutral-reverse quick shuttle switch and transmission downshift button. A digital display records real-time data and diagnostic information, and allows programming of operational modes.

Ground-line service checks contribute to the 1221E’s easy maintainability. Fluid sight gauges are positioned at eye level, and three remote drains for coolant, engine oil, and hydraulic oil provide convenient access for fast, environmentally friendly fluid changes.

A Ride Control option helps to boost productivity by reducing shock loads on the machine and operator, which also helps to maximize material retention while transporting a load. Ride Control can be set for full-time mode or auto mode, which activates when the wheel loader is driven at speeds above 6 mph (10 km/h).
