Four rope grab
The four-rope grab is mainly used in conjunction with bridge or gantry cranes to grab various accumulated loose materials for loading, unloading, transfer, and feeding operations. According to user needs, it can be designed with teeth, parallel girder opening, underwater operation and other forms.
Electric hydraulic grab
The grab adopts electrical, hydraulic and mechanical technology, with high degree of automation, large grasping force, high efficiency and energy saving. It is an ideal loading and unloading tool for bulk materials such as pig iron, scrap steel and ore.
