When your Sandvik drill rig's boom is drifting, lagging, or losing slewing torque, the slew or rotation motor is almost always to blame. We supply heavy-duty, direct-fit complete hydraulic slew and rotation motor assemblies engineered specifically for Sandvik underground jumbos (DD series), longhole drills (DL series), and surface drill rigs (Leopard, Pantera, Ranger, and DR series).
- Massive Slewing Torque: Engineered to original factory performance metrics to deliver rapid acceleration and unwavering power — even when positioning heavy booms underground or on uneven benches.
- Zero-Drift Hydraulic Braking: Equipped with premium integrated relief valves and mechanical parking brake groups. When the operator releases the control, the boom holds — no overshoot, no dangerous drift.
- Complete Drop-In Assemblies: Our units come fully assembled with the complete motor group, integrated valve block, and heavy-duty splined drive shaft — ready to mate with your existing slew gearbox.
Give our heavy machinery parts team your Sandvik model number and machine serial number — we'll quickly locate the exact direct-fit replacement to eliminate your downtime.
