The Trilift® Cat 797 Transmission Hoist is a specialised Trilift® hoist designed to assist with the removal and installation of Cat 797 transmissions without removing the truck body.

The hoist frame has been designed to allow placement on the truck chassis using the workshop overhead crane. Hoist hydraulic functions include winch raise / lower, winch portal extend / retract and transmission right / left rotate or tilt via two additional  cylinders. Available in two models air powered or diesel powered

The CAT 797 Transmission Hoist is available in 2 models:

• The standard CAT 797 Transmission Hoist D is powered by a self-contained Tier IV pollution rated diesel motor powering the hydraulic pump. (Part No. TL12004)

OPTIONAL JIGGING 
The Trilift® Cat 797 Transmission Hoist Cradle (Part No. TL12108) allows Cat 797 transmissions to be stored while not in use or transported to and from the Cat 797 Transmission Hoist during the change out process.

The Trilift® Cat 797 Transmission Hoist Transport Frame (Part No. TL12090) allows for a Cat 797 transmission to be moved safely, with a forklift, outside the workshop environment.  The Transport Frame can also be used to transport 797 Transmission Hoist in two (2) halves, fitting neatly into a 20 foot container, for transport by road or sea.

The Trilift® Transmission Hoist has been designed to overcome the practical difficulties in removing and installing transmissions and differentials in heavy earthmoving equipment. Hedweld has designed a unique transmission hoist for Cat 776, 777, 785, 789, 793 and Kress Haulers. (Part No. TL12002)

Traditionally a transmission and differential were removed and installed by lifting them through the top of the chassis rails. The Transmission Hoist is capable of removing and installing these components by lowering through the bottom of the chassis.

Available Trilift® Jigs and additional tooling suited for the Trilift® Transmission Hoist include:

•Differential Removal Jig (Standard with Transmission Hoist)
•Optional Final Drive Jig (Part No. TL12102) can be installed to provide accurate operation for removal and replacement of Cat final drives  jigging is adjustable to accommodate Cat 776/777, 785, 789 and 793 final  drive units.

To enable removal of the transmission from the confined space under Cat 776, 777, 785 and 789 trucks using the Trilift® Transmission Hoist, the rear of the truck needs to be raised. To allow clearance for the removal of the transmission, Trilift®  offers two different options, the Transmission Removal Stands (Part No. TL12101) and Ramps (Part No. TL12103) are available.

The Trilift® Wheel Stands are placed under the outside set of wheels.  This allows clearance for the removal of the transmission under the differential. The stands are adjustable in height to suit the various models of Cat trucks.

The Trilift® Wheel Ramps section allows the truck to be driven into place in a safe and efficient manner and are designed to accommodate the various models of Cat trucks.
