The design of the grab bucket structure is reasonable and good steel, grasping the weight of material and grab the ratio of 1.5-1.92, full degree to reach 95-100%, the main bushings using bearing steel, pulley on the use of high temperature bearings, plus two-port rubber oil seals, dustproof waterproof can be used underwater. The cutting edge adopts wear-resisting alloy structural steel as the cutting edge plate, which is convenient for welding and maintenance and good impact.

The principle of the pike-type grab:

Because of his unique structure, more conducive to grasping carriages, cabin corner materials, compared with the common long brace grab has the following characteristics: bearing beam structure is short, high strength, weight reduction, struts for closed welded structure, independent transmission, stability, lateral bending ability. The main hinge points of the sleeve using bearing steel, PIN shaft using alloy structural steel, in order to prolong the life of the bucket 3-4 times, the board using wear-resistant alloy electrode, network, surfacing, increase impact and wear resistance, long service life, crawl than to reach 1.8T. This grab is novel in shape and reasonable in structure, and it is the ideal grasping tool for loose materials with small granularity, which is generally suitable for port, wharf, cargo station, grasping coal, grain, slag and other loose materials.
