Product Selection · Application Guide
The full-system configuration — QJM radial piston, BM3Y orbital, and ZCM3 transmission covering pumping, auxiliary, and slew from one supplier.
The strongest argument for single-source hydraulics is a machine like this: three different drive technologies on one truck, all needing matched pressures, interfaces, and one accountable supplier.
Motor roles in this machine
- QJM — pumping-side drive: Steady radial piston torque for the pumping and distribution functions. QJM reference →
- BM3Y — auxiliary drive: Direct-flange orbital motor for agitator and secondary functions. BM3 reference →
- ZCM3 — turret slew: Motor + gearbox + fail-safe brake in one sealed unit for boom rotation. ZCM reference →
