On-Board Training Simulator for Off-Highway Equipment

A training device to improve the training of off-highway mobile equipment operators has been developed by the Bureau of Mines through a contract with Woodward Associates, Inc. The device, called OBSAC (for On-Board Simulator for Abnormal Conditions), is discussed in terms of its use in several training situations. Though the discussion is related primarily to off-highway hauler operator training, the principles can be applied to train operators of other off-highway machines. The training concept which the OBSAC reflects is appropriate for several types of off-highway equipment.
