Crane Grab Buckets
Crane grab buckets are specialized lifting attachments designed for handling bulk and loose materials in overhead material handling systems. They consist of grab shells (jaws), a driving mechanism (mechanical, hydraulic, or motorized), suspension system, and control components, enabling efficient grabbing, lifting, and unloading operations.
These grab buckets deliver high productivity and reliable performance across a wide range of industrial environments. Whether referred to as clamshell grab, orange peel grab, hydraulic grab, or mechanical grab bucket, the core function remains consistent: safe, efficient, and precise bulk material handling.

FAQs About Crane Grab Buckets
A crane grab bucket is a lifting attachment used with cranes to handle bulk materials such as sand, coal, ore, scrap metal, and waste. It operates by opening and closing its jaws to grab, lift, and release materials efficiently.
Common types include:
- Mechanical grab buckets (rope-operated)
- Hydraulic grab buckets (electro-hydraulic)
- Motorized grab buckets
- Clamshell grab buckets (for bulk materials)
- Orange peel grab buckets (for scrap and irregular materials)
- Dredging grab buckets (for underwater operations)
Selection depends on:
- Material type (bulk, scrap, fine particles)
- Material density
- Crane type and configuration
- Required capacity and cycle time
- Working environment (indoor, outdoor, underwater)
👉 For example:
- Bulk materials → Clamshell grab
- Scrap metal → Orange peel grab
- Heavy-duty operation → Hydraulic grab
