Mechanical Clamshell Grab Bucket

The Mechanical Clamshell Grab Bucket is designed for efficient bulk material handling in overhead crane and gantry crane systems.

This grab operates through a mechanical rope system, using crane wire ropes to control opening and closing actions. It is widely used in ports, steel plants, power stations, and bulk cargo terminals.

Working Principle

The grab bucket operates by dual-rope or four-rope mechanical control:

• One rope supports the grab body

• The other rope controls opening and closing

• No hydraulic or electric drive system required

This structure ensures simple operation and reliable performance.

Key Features

Heavy-Duty Structural Design

Manufactured from high-strength steel plates to withstand impact and abrasion during bulk material handling.

Efficient Material Penetration

The clamshell bucket design allows strong penetration into materials such as coal, sand, ore, and grain.

Stable Linkage System

Reinforced link arms and hinge pins ensure synchronized movement and balanced closing force.

Low Maintenance

Without hydraulic systems or motors, mechanical grabs offer:

• Lower maintenance cost

• Simpler structure

• High reliability

Customizable Capacity

Available in various capacities and bucket volumes according to material density and working conditions.
