A grab overhead crane is a lifting equipment that combines a bridge crane and a grab mechanism. It is mainly used for handling and loading and unloading bulk materials. It consists of a bridge, a cart, a trolley, a grab mechanism and a control system. The lifting, walking and grabbing actions of the grab are realized through the movement of the trolley and trolley.
During the working process of the grab overhead crane, the cart moves along the track of the bridge and is responsible for moving the grab from the stockyard or truck to the target location. The trolley moves along the beam of the trolley and is responsible for positioning the grab bucket to the specific grabbing point. When the grab reaches the target position, the grab mechanism is driven by the hydraulic system or motor to open and close the grab. When the grab is open, the material can be grabbed into the bucket; when the grab is closed, the material is tightly fixed in the bucket to ensure safe transportation.
The control system is an important part of the grab overhead crane and can be operated through joysticks, buttons or remote controls. Operators can precisely control the movement of the crane and the action of the grab to adapt to different operating needs.
The grab overhead crane is efficient, flexible and reliable, and is suitable for the loading and unloading needs of a variety of bulk materials, such as coal, ore, sand and soil, etc. Due to its large load capacity and wide operating range, grab overhead cranes are widely used in ports, logistics warehousing, mining and other fields.
