EH Series Gearboxes

Track-drive planetary gearboxes designed for heavy machines, high shock loads, and broad ratio combinations.

EH Series track drive gearbox

Gearbox series

EH Series

EH Track Drives are engineered for severe-duty traction applications with torque ranges from 100,000 to 900,000 Nm.

Their architecture uses high-strength carriers and case-hardened gears to support shock resistance, radial loading, and long-life operation.

100,000 to 900,000 Nm (track-drive range)
