The HZPT planetary transmission has a variety of track transmission series. These drives are used for crawler driven machines, such as hydraulic excavators, drilling rigs, bulldozers, cranes, etc. These track drives have a rugged design with tapered roller bearings and are available in single, double or triple stages depending on the speed ratio. If required, equip the parking brake and neutral device.
Track Drives
400T series track drive planetary gearbox is a special gear reducer for tracked vehicles and earth moving machinery. The reduction gearbox has a heavy housing, short overall length, and large radial and axial load capacity.
Our gearbox is equipped with an integrated multi disc parking brake designed for direct mounting of hydraulic plug-in motors. The carefully selected materials and designs enable our gear reducers to be used in the worst environments. 400T series gearbox is the perfect transmission solution for crawler landing gear, drilling, crushing, screening and pile driver.

Track drive system
The track drive system pushes the paver. The track drive system is a parallel system that drives the left and right tracks. The main components of the track drive system are as follows:
- Hydraulic propulsion motor.
The hydraulic propel motor is a two speed fixed displacement motor. High speed or low speed selection is made by the movable internal port board. The high speed or low speed port plate position is controlled by a solenoid valve activated by a travel switch on the operator’s instrument panel. The motor shaft is matched with the reduction gearbox. The hydraulic power of the drive motor is provided by the hydraulic propulsion pump. - Reduction gearbox and brake
The reduction gearbox is mounted to the drive hub assembly from inside the paver frame. The gearbox converts high speed and low torque input into low speed and high torque output. When all hydraulic power is lost or the control handle is placed in the neutral position, the hydraulic release brake with an integral spring is engaged. - Drive sprocket gear.
The drive sprocket is directly connected to the drive hub shaft inside the drive hub assembly and to the reduction gearbox. The shaft rotates on two sets of tapered bearings. The drive sprocket is bolted to the outer side of the drive hub assembly
