A drill rig repositions constantly on rough, sloped ground — the undercarriage needs high tractive torque, a fail-safe parking brake, and full sealing against dust, all inside the track frame envelope.

Motor roles in this machine

• ZCM — track drive: Hydraulic motor + planetary reduction + spring-applied brake as one factory-sealed assembly. The rig holds position on slopes automatically when flow stops. ZCM reference →
• One interface, no alignment work: The integrated unit bolts to the track frame and sprocket directly — no motor-to-gearbox matching, one warranty, one supplier.
