Single-rope grab
Single rope grab is only applied to the crane with a lifting rolling drum. Switching mechanism is novel and is operated freely when lifting weights. It is used on the ground or under the water. It can be classified into X type and U type.Four-rope grab
Four-rope grab mainly matches with bridge cranes or gantry cranes. It grabs all kinds of piled loose materials to load, unload, transport, pile and add. We can design grabs with tooth, parallel girder opening and working underwater etc. according to what customers require.Electric hydraulic grab
Electric hydraulic grab adopts comprehensively electricity, hydraulic, mechanical technology. Degree of automation is high. Grabbing force is big. It is energy-efficient, an ideal tool to lift iron, steel and ore materials etc.parameter
