At least one intermediate supporting member is provided to extend between the ramp member and the base member, supporting the ramp member at an acute angle relative to the base member. Positioned for constrained sliding engagement within the slot or guide means is a load contacting member, the movement of which longitudinally of the device, is limited by the slot parameters. Finally, the device is completed by a transverse member attached to the under-surface of the base member at a point approximately one-third of the length of the base member from its attachment point with the ramp member. This additional member is substantially V-shaped, the apex being the ground en- gaging portion. The purpose of this member being to provide a fulcrum about which the device, whin in use, may pivot.
