Mechanical Grab Bucket
APR Bright Industries has been manufacturing high-performance Mechanical Grab Buckets since 2004. We specialize in the design and manufacture of Single-Rope, Two-Rope, and Four-Rope grabs in both Clamshell and Orange Peel (Cactus) configurations. Built with high-tensile, wear-resistant steel (HARDOX®), our grabs are engineered to minimize dead weight and maximize payload for ports, steel plants, and dredging operations worldwide. We ensure a 95–100% fullness degree to significantly enhance your operational productivity.
Our high-efficiency mechanical garbs are precision-designed to integrate with ship deck cranes, overhead cranes, gantry cranes, and advanced port unloading cranes. Grabs are built with high-tensile material and FEA-optimized designs , and recue the dead weight up to 15%.


Single-Rope Mechanical Grabs (Touchdown & Remote)
Our single-rope grabs are specifically designed for cranes with a single hoisting drum, such as Ship Deck Cranes and Crawler Cranes. These mechanical grabs are available with Touchdown (Automatic), Manual Trip, or Radio Remote Control features, enabling a self-triggering mechanism for precise opening and closing during material discharge.

Two-Rope Mechanical Grabs (Holding & Closing)
Engineered for cranes utilizing a two-line system (one holding rope and one closing rope), our grabs meet the highest industry standards for charging and discharging bulk materials including gravel, sand, and coal. The robust articulated design offers superior digging force and long-term structural durability.

Four-Rope Mechanical Grabs (Heavy-Duty)
For high-volume, heavy-duty operations at ports and ship-to-shore cranes, APR offers specialized Four-Rope Grabs. Equipped with two opening and two closing ropes, these grabs provide extraordinary stability and a capacity range from 5t up to 100t. They are the ideal solution for handling coal, coke, and scrap metal in high-capacity.
