Custom CMH hydraulic power unit for the railway sector, supporting equipment for the construction, laying and maintenance of track. It drives the lifting and clamping circuits with reliability and operational continuity.
In the railway sector, where machines often work in repetitive, heavy and prolonged cycles, the hydraulic system must ensure precision, stability and operational continuity.
This CMH hydraulic power unit was engineered for applications on machines used for the construction and management of railway elements. The main objective is to ensure precise flow distribution to the various services, keeping operation stable even during continuous work phases.
Flow splitting is a central aspect of the application: it allows several machine movements or functions to be fed in a controlled way, reducing irregularities and imbalances during the operating cycle. For this reason the choice of components, the sizing of the circuit and the integration of the hydraulic valve blocks are defined according to the real work the machine has to perform.
Another fundamental element is temperature management. The presence of a heat exchanger helps keep the oil within more stable working conditions, improving service continuity and protecting the reliability of the entire hydraulic system.
CMH develops custom hydraulic power units for industrial applications where assembling standard components is not enough. Every system is designed starting from the required function: flow, pressure, work cycle, available space, operating environment and maintenance needs.
In the railway sector this approach is particularly important, because machines must work with precision, repeatability and robustness. The power unit therefore becomes an active part of the machine’s performance, not a simple power pack.
CMH Oleodinamica designs, builds and tests hydraulic power units in Italy, with attention to build quality, a clean layout and consistency between the hydraulic design and the final function of the machine.
