Caterpillar has released the extended high lift option for the Cat 994F wheel loader.
The addition of the extended high lift (EHL) provides an extra 1075millimetres of dump clearance compared to the high lift linkage.
This extra lift makes it easier for the operator to load a 250 ton size class truck and enables them to dump the last pass without pushing material.
For faster cycle times, an operator can back the wheel loader away from the truck without racking back the bucket.
Centering the load, for reduced truck wear, better truck handling and less spillage has also been improved.
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 percent, which resulted in a 5 percent increase in production.
The 994F equipped with EHL linkage is rated at 32 metric tons 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.
Powered by a Cat 3516B HD EUI engine, the wheel loader has a gross power of 1176kW and net power of 1092kW.
The updated 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.
The Cat wheel loader also includes the Rimpull Control System which enables the operator to set rimpull below 100 percent 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.
