Accumulator, HEMM (Heavy Earth Moving Machines), Hydrostatic Steering System, Off-Road Vehicle.


Heavy earth moving machines (HEMM) and trackless offroad equipment are extensively used in mining operations. The confined working space in mining operations demand low turning radius for such machines. Therefore, they have articulated bodies steered through hydraulic system for ease of control. The steering operation of the vehicles is usually intermittent and subjected to variable load conditions. Conventional hydraulic systems are difficult to adjust for such load with respect to energy consumptions. This paper describes a review on novel hydrostatic steering control system which turned out to be extensively applicable to heavy earth moving equipment and trackless off-road equipment. In hydrostatic steering system, the steering wheel and steering column are hydraulically connected by pipes and hoses and a variable displacement pump is used that delivers pressurized fluid through hydraulic valves to hydraulic cylinders which in turn moves tools of heavy earth moving machines (HEMM) such as shovels, buckets and steering mechanisms. The paper presents a review on the application of accumulator for improving efficiency of hydrostatic steering system.
