SELF-TRAVELING DOLLY CONTAINING HORIZONTAL CONTROL FUNCTION
Document Type and Number:
Japanese Patent JPS59212923
Kind Code:
A
Abstract:
PURPOSE:To prevent the fall of loads from a dolly despite a slope of the floor surface by giving control to keep the horizontal state of a load receiving bed. CONSTITUTION:Slope detectors 13a and 13b are attached toward the diagonal lines of universal wheels 3-6. Then weights 12a and 12b which are sent out and pulled in by guide rails 15a and 15b and drivers 10a and 10b at both sides are set at the upper or lower position which is coaxial to the detectors 13a and 13b. While a weight shift control part 37 is provided to a universal wheel drive control part 9. In addition, springs 18 and 19, etc. which vary their length by the loads are attached between the wheels 3-6 and a bed 2. As a result, the bed 2 is always kept horizontal and therefore the fall of the loads can be avoided despite a slope of the floor surface.
