Bulk material handling plays a vital role in ports, mining, steel plants, biomass facilities, and many other industrial applications. One of the key pieces of equipment used for efficient handling of loose and heavy materials is the mechanical grab. These robust tools are attached to cranes and loaders to scoop, lift, and transfer materials like coal, sand, biomass, scrap, wood chips, fertilizers, and minerals.

Here’s a detailed breakdown of the main types of mechanical grabs and how GrabsIndia.com can offer cutting-edge solutions for your handling needs:

🔹 1. Clamshell Grab (Double Rope / Single Rope)

Single rope: Designed for cranes with a single drum; uses an internal closing mechanism.
Capacity: Ranges from 0.5 m³ to 25 m³
Features:
Wear-resistant high-strength plates (like HARDOX/SUMIHARD)
Precision closing edges
High loading efficiency

🔹 2. Orange Peel Grab (Electro-Hydraulic / Mechanical)

Function: Best suited for handling scrap metal, waste, and irregular bulk materials.
