What is a Creep Drive? • A creep drive is an hydrostatic transmission that will be

installed on an existing mechanical transmission of a truck to allow a regular and relatively slow motion.

• The Creep Drive is installed on the driveline between the truck gear box and the rear axle(s)

4

• In transport mode the creep drive motor is disengaged and the truck uses its mechanical transmission between 0 to 100 km/h (0 to 65 mph)

• In the creep drive mode the mechanical transmission is in neutral. A pump fitted on a PTO drives the Creep Drive motor which is engaged. The truck speed will be from 0 to 8 km/h (0 to 5 mph)

Features and Benefits

Features and benefits of all the Creep Drives• Allows an easy control of a regular continuous low ground speed

without playing with the clutch of the mechanical transmission. ⇒ Cost saving on maintenance.

• Allows hydrostatic braking. No need to use the mechanical brakes. ⇒ Cost saving on maintenance.

• No impact on drivability or efficiency at transport speeds.

• Easily integrated into remote control systems.

• High overall efficiency and excellent starting torque.
