Wireless Remote Control Grab
Wireless Remote Control Grab Quality Advantage


Wireless remote control grab, widely known as a new type of single rope grab, is typically used for handling bulk material cargoes. Our grabs are equipped with a hydraulic system to control the closing of the grab. By pressing the remote control a signal is sent to the grab. The receiver that is inside the grab activates an electro-magnetic valve inside the hydraulic system, which starts the opening of the scales. The key components of electrical and hydraulic systems are of recognized brand imported. The water-proof design of the grab allows for all weather operations. Wireless remote control grabs are specifically used for loading and unloading application in ports and terminals.
Available from 2.2 M3 to 10 M3 and for lifting capacities from 7.5 to 32 ton
There are dedicated grabs for various common bulk materials.


Used for handling various kinds of materials including grain, coal, ore, metal, plastics, cement, clinker, gravel, etc. The grabs can be fitted on all type of cranes: mobile, crawler, port, ship, etc.
