Railway hydraulics

Hopper wagons are used for the mass transportation of raw materials like ore or coal. The vehicles and in particular the installed hydraulics are subject to extreme loads, including shocks, dirt, and climatic conditions. Short discharge cycles and a high degree of operational reliability are required to ensure the fast handling of the raw materials.

Roth hydraulic systems meet these requirements. They serve the energy-independent opening/closing of side flaps, roofs and slides on hopper wagons in the railway hydraulics. The systems are delivered ready for installation and consist essentially of the following components:  

Roth wheel set pump
Roth piston accumulator with patented load shutdown 
Hydraulic control
Hydraulic oil tank
Cylinder/motors to the damper drive
Ready to install piping kits
Available with optional patented remote control
Effective volume: application-specific, scalable

Temperature range: -40° C ... +50° C
