China Four Rope Special Type Scissors Grab

Scissor type bulk grab is designed and manufactured with the principle of scissors, which has many characteristics such as large open degree, short drawstring, strong excavating force, high grabbing ratio and high working efficiency. Since its moving grasping curve is nearly horizontal, it is an ideal handling tool of bulk cargo such as mine, mineral powder and sand gravel.
The grab has steel wire rope as its balance device, which can balance the forcing of steel wire rope and lengthen the working life of it. The distance from steel wire rope's opening to its closing is two thirds of that of long brace bulk grab. Handling cycle at a time of the grab can save 20% of that of long brace bulk grab, equivalent to improving 20% tonnage of ship unload, which greatly increases the handling efficiency. With a large open degree, the scissor type grab is particularly favorable for grabbing the materials around the cabin and can replace pushing raking machine to work in the cabin.
Our company has manufactured many scissor type bulk grabs in batches in these years, mainly used in handling coal and mine power in domestic and foreign ports.
