摘要
A load elevator for pallets comprising a load supporting platform (2) connected to a base frame (1) through scissor linkages (23,25), a pair of compression springs (3,4) interposed between the platform (2) and the base frame (1), the capacity of said springs (3,4) being selected according to the formula: MATH wherein C is the spring capacity in kilograms, W is the weight of the load in kilograms and H is the height of the load in millimeters, such that when a predetermined load W is supported by the platform (2), the springs (3, 4) will be substantially fully compressed and will operate to automatically elevate the platform (2) as part of the load is removed from the platform (2) whereby the top portion of the load remains at substantially the same height.
