Bulk material grab is a heavy-duty bucket that uses a hinged mechanism to scoop and lift loose materials. These grabs are essential for efficiently loading and unloading materials like coal, ore, grain, sand, and scrap metal in construction, manufacturing, and shipping industries. Different types of grabs, such as clamshell grabs, orange peel grabs, are designed for specific materials, with designs optimized for factors like density, grain size, and how easily the material flows.
Hydraulic grabs are widely used in industries requiring efficient handling of bulk materials:
Ports and docks: Loading and unloading bulk cargo such as coal, ore, grain, and fertilizer.
Material transfer yards: Iron and steel mill ore and coke storage yards; power plant coal yards.
Construction engineering: Excavating and transferring sand, gravel, soil, and crushed stone.
Recycling and environmental protection: Grabbing scrap steel and waste materials; handling and sorting municipal solid waste; sludge removal from sewage treatment plants.
Mining: Loading ore in conjunction with excavators.
Railway freight: Clearing remaining materials from bulk freight cars.
Grab Bucket Types:
Number of Jaw Flaps:
Double-Lapse Grab Bucket: The most versatile, suitable for most bulk materials.
Multi-Lapse Grab Bucket (e.g., 5-6 lobes): Used for grabbing scrap steel, large irregular stones, and household waste, providing a more stable grip.
Clamshell Grab Bucket: Two lobes are shell-shaped, providing excellent sealing when closed, ideal for granular materials such as grains and cement where leak-proof requirements are high.
Structural Design:
Lightweight: Used for low-density materials.
Heavy-Duty: Reinforced structure, used for ores, etc.
Extra-Heavy-Duty/Scrap Steel Grab Bucket: Made of special steel with reinforced teeth, used for extreme working conditions.
Hydraulic grabs are key tools in modern bulk material handling systems, characterized by high efficiency, power, and intelligence. Proper selection and matching with the host system, combined with good operation and maintenance, can greatly improve the productivity, safety, and economic benefits of loading and unloading operations. When choosing a grab, it is essential to communicate thoroughly with professional manufacturers or suppliers regarding specific working conditions.
