description In an earth-moving vehicle, a step assembly having a step member and an attachment device is affixed outwardly of the frame of the vehicle to allow longitudinal displacement of the step member upon contacting an obstruction. The attachment device comprises a plurality of flexible members each having a flexible cable with rigid threaded rods affixed at each end for securing the step member to the vehicle frame or bracket affixed thereto; and an elastomeric tubular member encompassing the flexible cable, the elastomeric member acting as a spacer to spatially remove the step member from the vehicle frame while allowing the step member to deflect longitudinally relative to the vehicle frame upon contacting an obstruction adjacent to the path of the vehicle and to return the step member to its operating position upon clearing the obstruction. The attachment means while allowing longitudinal deflection, limits downward deflection relative to the vehicle frame when the step is used by an operator or repairman in mounting or dismounting the vehicle.
