Types of Grab Bucket EOT Overhead Crane

The Grab Bucket EOT Overhead Crane features different types of grab buckets to meet the handling needs of various bulk materials and waste. Different grab bucket designs are tailored to material characteristics and operating environments, capable of handling both conventional bulk materials and irregularly shaped or high-density materials. Below is an introduction to two common types of grab buckets.

Clamshell Grab Bridge Crane

Clamshell Grab Bridge Cranes are used for handling bulk materials such as coal, ore, sand, gravel, and grain. They feature a single or double girder structure equipped with a clamshell grab and electric drive, offering high grabbing efficiency, smooth operation, a compact structure, and easy maintenance. They are used in power plants, steel mills, cement plants, grain silos, and other bulk material storage facilities.

Parts of Grab Bucket EOT Overhead Crane

The grab bucket EOT overhead crane, which is used for handling bulk materials, relies on the coordinated operation of various key components. Each component plays its own role in ensuring the smooth operation of grabbing, lifting, moving, and unloading. Below, we will introduce these main components and their functions.

رافعة علوية بخطاف ذات حوض امساك

العارضة الرئيسية: Supports the lifting mechanism and grab bucket, extending along the bridge deck to ensure stable operation of the entire machine.
End Beam: Connects the bridge frame to the running wheels, supporting the bridge frame’s movement along the track.
Travel Mechanism: Drives the crane to move laterally or longitudinally along the track.
Grab Bucket: The main tool for grabbing, lifting, and unloading materials; available in clamshell or orange-peel types depending on the material.
Hoist Mechanism: Includes electric hoist or hydraulic drive, used for lifting and lowering the grab bucket.
Control System: Manual, remote control, or automatic operation options are available.
Wheels: Provide running support for the bridge frame and end beams, enabling smooth movement.
Safety Devices: Limit switches, overload protection, and anti-collision devices.

مبدأ العمل

The grab bucket EOT overhead crane primarily moves laterally along the tracks via the bridge structure, while the grab bucket is raised and lowered by the hoisting mechanism to grab and unload bulk materials. During operation, the grab bucket opens and aligns with the material, descends to the material pile to grab the material, then closes. The hoisting mechanism then lifts the material to the designated height, and the bridge or trolley moves the material to the unloading position, where the grab bucket opens to release the material. This entire process can be carried out continuously to complete loading and unloading operations. The control system allows for manual, remote, or automatic operation, ensuring stable and safe operation.
