Clamshell grab buckets are multifunctional lifting equipment designed for bulk cargo handling and dredging projects. They are suitable for efficient grabbing and transportation of loose materials such as sand, ore, and coal. Special models for dredging or desilting can also be customized according to operational requirements. The equipment adopts a modular design, combining high-strength materials and precision transmission systems to ensure stable operation under complex working conditions such as ports, mines, and water conservancy projects.
Material and technology of the clamshell grabs
Main structure: Made of high wear-resistant alloy steel, integral casting, hardness of key parts, wear resistance increased by 3 times, service life extended several times that of traditional steel.
Bearing system: Equipped with heavy-duty sealed bearings, passed the IP68 protection level test, can completely prevent dust and water vapor intrusion, and adapt to extreme temperature environments from -30℃ to +80℃.
Surface treatment: hot-dip galvanizing process combined with wear-resistant coating, anti-corrosion performance meets C5-M marine environment standards.
Clamshell Grabs Optional
Model Rotation range Applicable scenarios Technical highlights
Mechanical rotation 270° (with height compensation), Port bulk cargo handling, ore transfer. Integrated 200mm hydraulic compensation device, automatically adapts to the change of grab height
Hydraulic rotation 360° continuous rotation Dredging engineering, underwater operations. Adopt a high-torque hydraulic motor, rotation speed of 0- 5 rpm adjustable
Slewing bearing 360° precise positioning Wind power installation, precision lifting Gear rack transmission + encoder feedback, positioning accuracy ±0.1°
Fixed No rotation Fixed position material handling Top design lifting plate + double lifting ears, suitable for a variety of lifting equipment
Special function extension
Clay cleaning system: An Optional high-pressure water jet or mechanical clay stripping device can effectively remove sticky materials (such as clay, silt) attached to the bucket body, and the cleaning efficiency is improved by 40%.
Dust leakage prevention design: The closed bucket body is equipped with a rubber sealing strip, and the dust suppression rate reaches 95%, which meets the EU ELV emission standards.
Quick replacement of bucket teeth: The wedge-shaped locking structure is adopted, and the bucket teeth can be replaced within 5 minutes without tools, reducing the maintenance time cost.
Application scenarios the clamshell grabs
Bulk cargo logistics
Port operations: sand and gravel supply at container terminals, automated loading and unloading of coal yards, with a single bucket grabbing amount accurate to ±2%.
Mining: ore sorting in open-pit mines, with crushers to achieve an integrated process of "grabbing-crushing-transportation".
Water conservancy projects
River dredging: The silt grab bucket is combined with a suction dredger, the silting depth can reach 25 meters, and the sand content processing capacity is 800m³/h.
Embankment maintenance: The rock grab bucket is used for embankment reinforcement projects, and the grabbing force exceeds 120kN.
