Automation of Working Unit on a Bucket Loader

For bucket loaders, the anticipated benefits of advanced machine control are increased capacity, decreased energy-consumption and improved safety. However, where dual automatic and manual modes of operation are to be maintained, it is important that the operator needs are taken into account. His level of attention must be above the threshold level of interest. In collaboration with FADROMA Construction Machines, Wroclaw, Poland, the authors have researched, designed, built and tested under both laboratory and site conditions, a bucket loader which can be operated under manual of automatic conditions. It has proved capable of excavating difficult granular materials. This has been achieved by detailed consideration of the motion requirements for excavation.
