Product Introduction
Grab Overhead Crane is a heavy-duty material handling solution equipped with a mechanical or electro-hydraulic grab bucket, designed for handling bulk materials in continuous, demanding industrial operations. Mounted on high-bay runway beams, it delivers efficient, automated, and dust-free loading, unloading, and stacking across harsh operating environments.

Product Advantages
Efficient Bulk Handling
Replaces manual hooks with specialized grabs (mechanical, electro-hydraulic, or motor-driven) to rapidly pick up loose materials without manual rigging.
Heavy-Duty Duty Class
Typically engineered to A6–A8 FEM/ISO duty ratings, featuring reinforced steel structures, heavy-duty gearboxes, and thermal-protected motors for 24/7 continuous duty cycles.
Versatile Grab Attachments
Compatible with orange-peel grabs for irregular scrap metal or clamshell grabs for fine granular materials, ensuring optimal filling ratios.
Advanced Automation & Safety
Supports semi-automated or fully automated PLC positioning, anti-sway controls, overload limiters, and anti-collision systems to maximize throughput and operational safety.
Typical Application Scenarios
Waste-to-Energy & Incineration Plants
Essential for mixing, stacking, and feeding municipal solid waste into incineration hoppers.
Steel Mills & Scrap Yards
Handles scrap metal, pig iron, and metallurgical slag under high-temperature conditions.
Ports, Terminals & Bulk Storage
Rapidly unloads coal, ore, sand, gravel, clinker, and grain from storage pits into conveyors or hoppers.
Cement & Chemical Processing
Moves raw limestone, clinker, gypsum, and bulk chemical powders across processing lines and storage silos.
