Benefiting from Poclain Hydraulics’ know-how in turret rotation solutions, the new range of MZ motors are more “concentrated” for integration into machines like mini and medium-sized excavators, as well as forestry, agricultural, and industrial turreted vehicles, where space for hydraulic features is limited. Unlike a high-speed motor and reducer solution, the MZ motor offers a yield of over 90% when operational, allowing it to efficiently use the power installed on the machine, thereby offering better acceleration and higher productivity, the company claims. The high yield also contributes to reducing the machines’ fuel consumption. The shockless and anti-rebound valves are completely integrated into the motor, eliminating all clearances and rebounds during the turret’s stop phase and helping to reduce cabin noise. Coupled with radial piston motor technology, these valves guarantee precise positioning of the excavator’s arm in conditions of optimal comfort for the operator, according to Poclain. The motor is fitted with a parking brake feature, and its pinion shaft can be easily adapted to the machines. A complete range of MZ motors has been developed to cover the range of smaller excavators, up to 8 ton (7.2 t).
