By understanding learn clamp device39。s working principle, the structure of the crane clamp device classified and analysis, through the analysis to determine crane design scheme clamp device design, Specific models, tier 1 transmission have used gear transmission,transmission device scheme design and analysis equipment stability. Using double pin shaft adjustable clamp device that USES clamp selfrespect, using automatic switch equipment control clamping objects. Adopted the general design method of mechanical design, mechanical design support software AutoCAD , design a lifting clamp device, lift the weight of hoisting speed, 100Kg of m/s, operation speed reaches m/s, handling objects without jam, fast and convenient, equipment operation is good.
