High-Performance Clamshell Grab Buckets for Bulk Material Handling

Apical’s Clamshell Grab Buckets are engineered for high-volume handling of bulk materials such as coal, ores, slag, sponge iron, ash, and fertilizers. Built with an electro-hydraulic operating system, these buckets provide superior cycle efficiency with opening/closing times of 10–15 seconds, reducing manpower dependency while maximizing throughput.

Our grab buckets are available in capacities ranging from 0.2 m³ to 13.0 m³, designed to handle bulk densities from 0.8 t/m³ to 3.4 t/m³. Operating at hydraulic pressures of approximately 160 bar and powered by a 415V, 50Hz, 3-phase supply, they offer energy-efficient performance compared to traditional DC magnet systems. Depending on plant layout, options include radio remote control, wire pendant systems, and specialized designs such as self-dumping or underwater variants.

Compatible with EOT cranes, Goliath cranes, and stationary cranes, Apical’s clamshell buckets are widely deployed in steel plants, ports, power plants, cement industries, and foundries where reliability under continuous duty is critical.
