Caterpillar has released a new Extended High Lift (EHL) option for the 994F wheel loader, enabling the machine to load Cat 793 and similarly sized trucks more efficiently. The new EHL linkage provides an extra 1m dump clearance compared to the previous High Lift (HL) linkage option.

The additional lift height makes it easier for the operator to load a 250-ton 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. Centring 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%, which resulted in a 5% increase in production. The 994F equipped with EHL linkage is rated at 35t and is a seven-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 also be available. New 994F wheel loaders also feature structural changes to both the front and rear frames for extended durability.
