Product Description

A crane grab bucket is a heavy-duty attachment designed for handling bulk materials like coal, gravel, and scrap metal. Built from high-strength, wear-resistant steel, it features hinged jaw flaps (typically 2-6 segments) that open and close to securely grasp materials. Compatible with various crane systems, it operates via electric (380V), hydraulic, or wire-rope mechanisms, offering load capacities from 100 kg to 50+ tonnes.

Engineered for durability, it includes hardened steel edges and replaceable liners to withstand abrasive environments such as steel mills and ports. The grab bucket ensures efficient operation with fast 5-7 second opening/closing cycles and a 2.5x safety factor for overload protection. Customizable jaw designs (clamshell, orange peel, scrap grapple) adapt to different materials, while optional automation features enhance precision in modern industrial applications. Ideal for demanding material handling, it balances strength, speed, and reliability.

Application Scenarios

Bulk Material Handling - Efficiently loads/unloads loose materials like coal, sand, and gravel at ports and construction sites.

Scrap Metal Recycling - Specialized scrap grapples handle shredded metal, wrecked vehicles, and industrial waste in recycling yards.

Agricultural Operations - Transfers grain, feed, and fertilizer in silos or storage facilities.

Waste Management - Processes municipal solid waste and demolition debris at recycling plants.

Mining Operations - Excavates and transports minerals, ores, and tailings in mining areas.

Steel Mill Logistics - Handles hot/cold scrap, pig iron, and raw materials in foundries.

Dredging & Salvage - Recovers underwater debris, sediments, or sunken materials in marine operations.

Our Advantages

High-Efficiency Material Handling
Processes 3-5x faster than manual methods with 5-7 second cycle times.

Superior Durability
Engineered for superior durability, the steel construction resists wear for 10,000+ hours in abrasive conditions.

Adaptive Jaw Configurations
Interchangeable clamshell/orange peel/scrap designs handle 50+ material types.

Precision Load Control
±2cm positioning accuracy with anti-sway hydraulic synchronization.

Overload Protection
2.5:1 safety factor exceeds ISO 4301 standards for heavy-duty operations.

Low Maintenance Design
Quick-change wear parts reduce downtime by 60% versus fixed buckets.

Automation Readiness
IoT-enabled models feature auto-weight tracking and collision avoidance.

Packaging & Shipping

Crane grab buckets undergo rigorous export-ready packaging starting with heavy-duty steel frame crates (8mm beams) lined with VCI anti-corrosion paper and desiccant bags to prevent moisture damage during transit, where critical components like hydraulic cylinders are vacuum-sealed while jaw flaps are secured by high-tensile nylon straps to eliminate vibration damage; the entire unit is then wrapped in waterproof PE film for maritime transport with options for containerization (disassembled units in 20'GP containers) or RORO handling for oversized grabs, supported by full documentation including EN 13155 load certificates, NDT weld reports, and HS code 8431.31.00 labeling-all shipments comply with IMDG Code standards with FCL/LCL sea freight choices, land transport via low-bed trailers (4.2m height clearance), and mandatory pre-shipment protocols like hydraulic pressure release and IP66 connector capping to ensure risk-free delivery within 15-30 days ex-works, including all-risk insurance recommendations for ocean voyages.
