In 1958, Poclain revolutionized the way Hydraulic excavators work with the introduction of the first cam lobe motor allowing a complete rotation of the turret. Today, the MZ motor is the legitimate successor to this prestigious history, benefiting from over fifty years of Poclain Hydraulics’ experience and know-how in turret rotation solutions.
Nowadays, construction workers are no longer simply looking for the best performing product at the best price, they are also looking for components that are more easily integrated into their machine: this is the case, for example, with mini and medium-sized excavators, where the space dedicated to the integration of hydraulic features is particularly reduced.
This is why Poclain Hydraulics, with the new range of MZ motors, offers a «concentrated» version of the technology that made them so successful and that is perfectly adapted to this task.
In terms of performance, the MZ range has all the necessary advantages to carry out efficient and accurate work:
• Unlike a high-speed motor + reducer solution, the MZ motor offers a yield of over 90% when operational, which allows it to make best use of the power installed on the machine, thereby offering better acceleration, resulting in higher productivity.
This high yield directly contributes to reducing the machines’ fuel consumption, a major stake for construction companies.
• The shockless and anti-rebound valves, completely «integrated» into the motor, ensure In 1958, Poclain revolutionized the way Hydraulic excavators work with the introduction of the first cam lobe motor allowing a complete rotation of the turret.

Integration, Comfort, Robustness New MZ Range progressivity and eliminate all clearances and rebounds during the turret’s stop phase. This also contributes to reduce noise in the cabin during these phases. Coupled with radial piston motor technology, these valves guarantee extremely precise positioning of the excavator’s arm in conditions of optimal comfort for the driver.
• Very specific work has been carried out during its design to ensure that this range of motors is particularly silent when operating, providing comfort for the driver.
• The precise positioning of the turret is assured while working on slopes for the elimination of drifting.
• Finally, this motor is fitted with a parking brake feature. All these characteristics, which are essential for turret rotation, have been optimally integrated into the motor, itself designed with compactness in mind, in order to promote its integration into a confined and complex environment.
This motor is supplied with a pinion shaft, that can be easily adapted to the machines. In these ways, Poclain Hydraulics significantly contributes to the reduction in development time and costs for its customers.
The most well-known manufacturers of excavators, as well as forestry agricultural and industrial turreted vehicles, have already been convinced by the MZ motor.
A complete range of motors has been developed to cover the entire range of smaller excavators, and up to 8T, which are particularly demanding in terms of integration and compactness.
At the same time, other motor offers from the MS range, recognized for their robustness and their great modularity, allow for equivalent performances on the bigger machines.
