Case Construction Equipment is entering the upper end of the quarry and aggregates sector with a pair of wheel loaders that can fill a 27t dump truck in three passes.

The new Case wheel loaders are the 1021F and 1121F, both powered by a Tier 4 Interim 9 litre Case/FPT diesel engine.

The 1021F has an operating load of more than 8t and the larger 1121F has an operating load of around 9t.

Redesigned bucket profiles provide increased penetration into the pile or the face, allowing faster fill and shorter cycle times, Case says.

With a carry position roll back angle of 51 degrees on the 1121F and 48 degrees for the 1021F, the revised buckets provide increased load retention on load and carry operations. The 1021F benefits from 20% larger loader arm pins. The Case Ride Control system further reduces loss of material when travelling, the manufacturer says.

The 9 litre engines meet Tier 4 Interim standards by using selective catalytic reduction (SCR). An idle-management feature further reduces fuel consumption, turning the engine off when the machine is idle.

Case has replaced the conventional overlapping radiators with an advanced cooling pack. Each radiator forms a side of the cooling pack, allowing improved air flow through the cooling cores and making cleaning with the reversible fan more effective. This system provides the constant fluid temperature that extends oil replacement intervals by 500 hours.

Heavy duty ZF axles incorporate an automatic locking front differential to provide maximum traction in all conditions with low maintenance cost and reduced tyre wear.

Options include rearview wide-angle camera and the Case joystick steering system, integrated into the left hand armrest.
