METHOD OF MAINTAINING AN UNMETALLED ROADWAY DURING LOAD TRANSFER AND A VEHICLE THEREFOR

摘要

A method of maintaining a roadway (2) during transfer of a load from a first location to a second location by a motorised vehicle (1) is described. The vehicle (1) may be a dumper truck and has a retractable blade (8) movable relative to the vehicle (1) between a retracted position (FIG. 1) and a working position (FIG. 2). The load is transferred in the vehicle (1) from the first location to the second location along the roadway (2), the blade (8) is moved to the working position after dumping the load and on the return journey the vehicle (1) acts as a grader to smooth undulations and ruts. The blade (8) is pivotally mounted and located between the front axle (5) and the rear axle (6, 7) and does not extend beyond the width of the vehicle. Unmetalled roadways on construction sites, quarries and mines may be maintained in good condition without the need to employ additional vehicles or hire separate grader vehicles.
