Spring asynchronous multi-jaw grab

The utility model discloses a spring asynchronous multi-jaw grab, which consists of a grab opening rope, a grab closing rope, an asynchronous mechanism, a support bar, an upper bearing beam, grapple tines, a lower bearing beam, an upper pulley and a lower pulley. The top of the upper bearing beam is equipped with a hanging point which is designed to connect the grab opening rope, and the under side of the upper bearing beam is equipped with a pulley seat which is designed to fix the upper pulley. The top end of the support bar is connected with the upper bearing beam and the lower end is connected with the grapple tines. And the grapple tines are also connected with the lower bearing beam. The top side of the lower bearing beam is equipped with a pulley seat which is used to fix the lower pulley. The upper bearing beam is packaged with the asynchronous mechanism which has a plurality of springs with the same number of the grapple tines. Every spring is connected with the corresponding grapple tine. When the grapple tine is hindered, the utility model will achieve an asynchronous grabbing. The grab increases the weight of the upper bearing beam and decreases the weight of the lower bearing beam, which is favorable for grabbing materials. The utility model increases the unloading efficiency, which is applied to unloading the bulk materials at the yards of the wharf, station or steel mill etc.
