Wireless remote control grab is usually used for single hook type cranes, which are reliable in operation and easy to operate. Compared with electric hydraulic grab, it does not require accessories such as cable reels and can be controlled remotely through the grab's own hydraulic system, solenoid valves, and remote control. It is widely used in industries such as ships, ports, stations, factories, and mines. It is an ideal tool for loading and unloading bulk cargo such as coal, fertilizers,sand, cement, mineral powder, and ore. The wireless remote control grab can operate in harsh environments such as high temperature, severe cold, dust, and rainy days without affecting its performance. The remote control distance can reach more than 100 meters. The grab uses high-performance lithium batteries, and can operate continuously for more than 48 hours after each charge.
