Double flap grab is an efficient construction machinery device. It consists of double jaws, hinges and drive mechanism.
Double flap grab is an efficient construction machinery device. It consists of double jaws, hinges and drive mechanism. There are three types of drives: hydraulic, mechanical and electric. Hydraulic drive controls opening and closing by cylinder expansion and contraction, which is powerful and suitable for heavy-duty scenarios. Mechanical drive relies on wire rope and pulley set, simple structure and low maintenance cost. The electric drive integrates a motor and reducer, and does not require an external hydraulic source, resulting in lower energy consumption. Double flap grab is commonly used in ports, mines and construction fields for loading and unloading bulk materials such as coal, ore, construction waste, etc. In practice, we can customize the jaw size to suit different materials.
With the development of intelligence, double-flap grabs are integrating monitoring and intelligent control. Lightweight design and new energy drive have become the direction. In the future, double-flap grabs will continue to evolve in the direction of high efficiency, environmental protection and intelligence.
