Grab Bucket Overhead Crane

Product Introduction

A Grab Bucket Overhead Crane is a special type of overhead crane equipped with a grab bucket for lifting, loading, unloading, and transferring bulk materials. It is widely used for handling materials such as coal, sand, gravel, ore, slag, limestone, fertilizer, grain, waste, and other loose or granular materials.

Unlike ordinary hook overhead cranes, a grab bucket overhead crane uses a grab bucket as the main lifting attachment. The grab can open and close to pick up bulk materials, making it highly suitable for material loading and unloading operations in warehouses, stockyards, workshops, power plants, ports, recycling stations, and industrial production lines.

Frequently Asked Questions About Grab Bucket Overhead Crane

1. What is a grab bucket overhead crane?

A grab bucket overhead crane is an overhead crane equipped with a grab bucket instead of a normal hook. The grab bucket can open and close to collect and release bulk materials, making it suitable for lifting and transferring loose materials such as coal, sand, ore, gravel, slag, grain, waste, and fertilizer.

2. What materials can a grab bucket overhead crane handle?

It can handle many kinds of loose and bulk materials, including:

• Coal
• Sand
• Gravel
• Ore
• Slag
• Limestone
• Fertilizer
• Grain
• Biomass
• Waste
• Scrap materials
• Industrial bulk materials

The grab bucket type and volume should be selected according to the density, particle size, moisture content, and flow characteristics of the material.

3. What is the difference between a grab overhead crane and a hook overhead crane?

A hook overhead crane is mainly used for lifting packaged goods, machinery parts, steel structures, molds, containers, and other objects with lifting points.

A grab overhead crane is mainly used for bulk materials. It uses a grab bucket to pick up, hold, transfer, and release loose materials. Therefore, it is more suitable for loading, unloading, feeding, and stockpiling bulk materials.
