Abstract

PURPOSE: To dispense with a separate buffer, simply site work, reduce the number of parts, eliminate specific space, and prevent metallic impact sound by imparting function of a buffer to a hydraulic jack itself for moving up/ down a cage device. CONSTITUTION: A cage device l moves up/down through an up/down path in extension contraction of a hydraulic jack 2 with a rod 4 being of multi-stage type, for example. In this case, buffer means 3 is provided to the hydraulic jack 3, in order to absorb shock when the cage device l is down at its lowermost end. For example, buffer means 3 of hard rubber material is fitted to outer periphery at upper end of a first rod 4a, and buffer means 3 of hard rubber material is fitted to outer periphery at upper end of a second rod 4b. Then, in the case of shock absorption with the first buffer means 3 hitting onto the second rod 4b, gap G is formed for both rods 4a, 4b not to hit each other. In the case of shock absorption with the second buffer means hitting a cylinder 5, gap G is formed between both two.
