For more efficient loading of 250-tonne class mining trucks

The Extended High Lift (EHL) linkage provides 1,075 mm more dump clearance compared to the High Lift linkage.
The additional lift height makes it easier for the operator to load a 250-tonne size class truck. For faster cycle times, the operator can back the 994F away from the truck without racking back the bucket. The additional lift also enables the operator to dump the last pass without pushing material. Centering the load, for reduced truck wear, better truck handling and less spillage, is easier, too.
The EHL linkage is designed to reduce operator fatigue, decrease loading time and improve daily production when loading 793 size trucks. In a 793 loading test with the new linkage, cycle time decreased 5.5 per cent, which resulted in a 5 per cent increase in production. The 994F equipped with EHL linkage is rated at 35 tonnes and is a 7-pass match with the 793.
The EHL Option consists of new lift arms, lift and tilt cylinders, tilt links and counterweight material, which is added to the interior of the rear bumper. An extended high lift kit for retrofitting 994F wheel loaders already in the field will be available. New 994F wheel loaders also feature structural changes to both the front and rear frames for extended durability.

Productive and durable loader
The Cat 3516B HD EUI engine powers the 994F and delivers 1,577 gross horsepower (1176 kW) and net power of 1,463 horsepower (1092 kW). The proven engine delivers high torque rise for fast engine response and fuel efficiency while maintaining long engine life.
The 994F retains the Steering and Transmission Integrated Control (STIC) system that enables the operator to use small movements of a single hand to steer and to make direction and gear changes. STIC enables smooth operation with minimum effort.
Also to minimise operator effort while improving productivity, the Rimpull Control System enables the operator to set rimpull below 100 per cent for optimum traction in poor underfoot conditions. The operator can reduce rimpull and ground speed by using the impeller clutch pedal, which is fully modulating for smooth control when digging and loading.
The 994F also features designs to reduce maintenance time and to make maintenance tasks easier and safer. The standard automatic lubrication system reduces maintenance time by automatically lubricating bearings requiring the most frequent attention. At the ground level service centre, a maintenance technician can fill or drain fluid reservoirs and tanks.
