Product Introduction
It is used in mines, steel mills, aluminum mines, ports and docks, large breeding farms, coal washing plants, garbage dumps, wineries, and paper factories.
Electric motor grab is commonly used on multi-purpose cranes.
It has its own opening and closing mechanism, which can load and unload materials at any height.
The productivity is higher than that of a single-rope grab, it is easy to use, disassemble and hang, and the loading and unloading power is high.
It is suitable for grabbing all kinds of loose materials, such as ore, sand and gravel, slag, ore powder, coke, coal, loose clay, silt, garbage, lead and aluminum blocks, gravel, scrap steel, pipelines, iron sheets, potatoes, and salt. It has a large grabbing capacity and is most suitable for grabbing ore.
The grab adds a cable reel to transport energy according to the lifting height.
The electric motor grab cannot operate underwater.
Electric motor grab is divided into two categories: high-power and low-power
Electric motor grab, high-power grab (with winch)
