CreepDrive Offering Expands!

Poclain Hydraulics is bringing even more value to our customers by strengthening our full systems offering. We are leveraging our efforts through a strategic restructuring of our organization in order to focus on system solutions. Our CreepDriveTM offering, with a new dedicated motor and pumps, all from our High Performance range of products, is a perfect example of our strategic focus. The expanded CreepDriveTM offering will address the needs of a wider range of applications. It is being introduced at INTERMAT Paris in April 2018 and will be available for sales starting autumn of 2018.

 Creepdrive

The CreepDriveTM system, a true hybrid mechanical-hydraulic transmission from Poclain Hydraulics, allows vehicles to work at very low constant speeds regardless of the engine speed, providing auxiliary systems with the power they need to perform work effectively. When the system is disengaged, the vehicle is able to drive at normal on-road speeds with no mechanical transmission efficiency losses.


The complete CreepDriveTM line-up contains two different sizes of motors, a range of pumps and the plug & play control kit including the CAN bus communication. The new motor called CDM20 provides up to 2,4l of displacement with two speeds (possibility to siwtch from full to half displacement). Considering the gear reduction ratio in the rear drive axle differential, the CDM20 can provide an overall torque ranging from 50 000 to 100 000 Nm (36 000 to 72 000 ft.lbf). Other new features include a reinforced shift cylinder as well as an extremely robust design. This new motor rounds out the existing motor range by offering twice the speed and three times as much torque. Despite this significant performance improvement, the motor length has only increased by 50 mm (2 inches) and remains lighter than comparable products to meet the needs and requirements of modshops. Integration into a wider range of vehicle applications, including medium commercial vehicles where constant speed and accurate positioning are essential, is now easier. CreepDriveTM removes the added stress on braking and clutching experienced with trucks working at low speeds as well as the additional maintenance required to keep those systems working properly. Replacing friction braking with hydrostatic braking acting as an integral decelerator reduces the need to feather the brakes. This allows for more precision and less opportunity for error helping operators
increase safety and productivity. Also, radial technology eliminates the need for an additional reduction stage and offers some of the highest efficiencies on the market. This reduces fuel consumption and noise, which is a key requirement for urban applications. Applications include: solar energy farm glass cleaning (see picture), road maintenance & road marking/stripping, bridge inspection, rail track maintenance, airport & road sweepers, mulching/chipping, snow cutting, suction dredging, and slinging amongst others. Contact your local Poclain Hydraulics dealer for more information and sizing for your vehicle. The full CreepDriveTM system will be on display at the Poclain Hydraulics Intermat booth in Hall 5A - Stand F046.

Operational tips
To enable the hydrostatic ground drive, the vehicle brake is applied and the mechanical transmission is set to neutral while the engine PTO is engaged to drive the pump that
supplies flow to the hydraulic motor. A switch located in the cab engages a pneumatically controlled mechanical clutch, which sets the mechanical transmission to neutral and
engages the hydrostatic transmission.
The driver sets the engine speed to the desired working rpm and, after releasing the brake, moves the joystick in the desired direction.
Consistent low working speeds (0,2 - 7mph) are achievable in both forward and reverse directions. When traveling at on-road speeds, the PTO clutch is disengaged and the mechanical transmission works at appropriate speeds.
