PETAL-TYPE MECHANICAL GRAB BUCKET
The petal-type grab bucket is mainly used for the load and unload of large wasted steel material efficiently under execrable conditions, and has been widely used in port, railway, metallurgy, mining, building and so on. Its structure has four types as single-cable, two-cable, four-cable and electric types. The jaw can open and close respectively according to material shapes and sizes so as to grab large materials, the quantity of jaw can be designed with 4-8 valvules according to the material sizes and clients’ requirements.
