In early 2009, Australian engineer, Shane Richardson, completed his thesis into the “Performance Criteria For Effective Structural Rollover Protective Systems For Light Passenger Vehicles”. Part of his thesis included an evaluation of the New Zealand Department of Labour’s ROPS guidelines for ATVs or quad bikes.
Richardson points out that the guidelines have strong similarities to the Australian Standard for protective Structures on Earth-moving Machinery (AS2294) although quad bikes may tipover or undergo a multi-directional tumble, the latter action is not one considered by AS 2294. Richardson believed that the earth-moving machinery “origin” of many of the basic concepts and calculations in the NZ DoL guidelines made them useful but inadequate.
