Size and weight limitations may require mobile equipment to operate with reservoirs as small as the volume a pump discharges in a minute. This is roughly a third the size of a reservoir traditionally used in an industrial application. The space and shape limitations mobile equipment places on reservoirs requires that they often be custom …
Mobile hydraulic systems pose a unique set of design challenges. The hydraulic tanks tend to be small, and often times the packaging problems are significant. My experience designing hydraulic systems for mobile equipment has ranged from systems with a few simple functions to complex designs with proportional control and feedback.

The challenges of mobile reservoir design. October 20, 2014 By Josh Cosford. Hydraulic oil spends most of its time in the reservoir, and as such, various tank design criteria provide benefits for the hydraulic system as a whole. When designing the optimum hydraulic reservoir, most of the considerations are in keeping the oil clean and …
Hydraulic layouts are addressed and categorized by both discussing their fundamentals and evolutions, and by pointing out their pros and cons in a way to provide …
Electro-hydraulic power units act as an alternative to the traditional gas/hydraulic-powered actuators common in hydraulic machinery. They function by utilizing available gas pressure within a pipeline. However, they aren't the exact same as a standard HPU. Electric HPUs are completely closed systems with their own internal hydraulic ...
Depending on the setup, it can move cars at speeds to 60 ft/min and generate 75,000-lb of thrust. Calbrandt's rail car mover uses a set of five hydraulic cylinders to move and position rail cars for loading and unloading. The cylinders can produce a stroke exceeding 78 ft and can move up to sixty 143-ton cars at a time. (Click image to enlarge.)

Reservoir Design for Mobile Equipment Hydraulic Circuits. WebReservoir Design for Mobile Equipment Hydraulic Circuits 700722 Hydraulic reservoir design for implement and steering circuits on track and wheel loaders plays a very important role in the performance of these circuits.
The most radical – and fuel efficient – versions of these hydraulic hybrids eliminate the traditional mechanical drivetrain altogether. In the vehicles, diesel engines drive a hydraulic pump-motor, which in turn charges a high-pressure accumulator. That accumulator drives a bent-axis pump-motor on the rear wheels to propel the vehicle.
