The HP2VC series variable piston pumps include: HP4VC45, HP2VC63.

The HA4VTG series variable piston pumps include: HA4VTG90, HA4VTG110.

The HAA2FM series fixed‑displacement piston motors include: HAA2FM56, HAA2FM63, HAA2FM80, HAA2FM90, HM2F110.

Standard Hydraulic Drive Configuration for Concrete Mixer Trucks

This is the most widely adopted drive arrangement. The engine drives, via a power take-off, a typical closed hydraulic circuit composed of HP2VC/HW or HA4VTG/HW variable piston pumps and HAA2FM fixed‑displacement piston motors. The motor then drives the mixing drum through an HL series planetary reducer. This solution features high reliability, flexible setup, smooth operation and easy maintenance.

HL Series Planetary Reducers for Concrete Mixer Trucks

The HL series planetary reducers for concrete mixer trucks satisfy performance requirements for mixing drums with capacities ranging from 3 m³ to 18 m³.

Each HL mixer planetary reducer is built as a basic two‑stage planetary gearbox and driven by an externally mounted hydraulic motor via a standard SAE flange. Its main bearings are FAG bearings manufactured by Schaeffler, Germany; oil seals are supplied by Simrit, Switzerland. The gears are made of imported German 17CrNiMo6 steel and carburized and quenched in imported German vacuum furnaces.

The HL series delivers superior technical performance with good cost efficiency. It operates reliably with low maintenance frequency and excellent wear resistance, and performs remarkably even under extreme operating conditions.
