Bulk Grab Overhead Crane: Ore, Coal, Sand and Slag

As a core equipment in bulk material handling scenarios, the grab overhead crane is specifically engineered to address the efficient, safe, and continuous transportation needs of ore, coal, sand, slag, and other granular or lumpy bulk materials. Our bulk material grab overhead crane integrates advanced structural design, intelligent control systems, and heavy-duty working performance, making it an indispensable heavy lifting solution in mines, power plants, cement factories, ports, metallurgical plants, and other industrial fields. Whether it is loading and unloading raw materials, transferring materials between workshops, or stacking finished products, this electric grab overhead crane can deliver stable and reliable operation, significantly improving handling efficiency and reducing labor costs.

Product Overview: Core Advantages of Grab Overhead Crane for Bulk Materials

Our bulk grab overhead crane is developed based on years of industry experience and market demand, focusing on solving pain points such as low efficiency, high labor intensity, and poor safety in traditional bulk material handling. The crane is equipped with a high-performance grab bucket (including hydraulic grab, mechanical grab, and electric grab options) that perfectly matches the physical properties of ore, coal, sand, and slag. Combined with the stable overhead crane structure, it realizes precise grabbing, lifting, and placing of materials. Compared with ordinary cranes, this heavy duty grab bucket overhead crane has stronger load-bearing capacity, better adaptability to harsh working environments, and longer service life, which can fully meet the long-term continuous working requirements of bulk material handling workshops.

Technical Parameters (Customizable According to Requirements)

Key Features: Why Choose Our Bulk Grab Overhead Crane?

1. Efficient and High-Capacity Grabbing Performance

The overhead crane is configured with a customized grab bucket that can be tailored according to the particle size, density, and humidity of different bulk materials (ore, coal, sand, slag). For example, the deep-tooth grab for ore ensures firm grabbing without slipping, while the anti-stick grab for wet sand and coal prevents material residue. The matching high-power hoisting mechanism and variable frequency speed regulation system enable the grab overhead crane to complete the grabbing-lifting-transporting-unloading cycle quickly. The working efficiency is increased by 30% compared with traditional manual handling, and the maximum single grabbing capacity can reach 50 tons, effectively meeting the large-volume material handling needs of large-scale factories and ports.

2. Stable and Durable Structural Design

Adopting a double girder grab overhead crane structure (or single girder structure for small-tonnage scenarios), the main beam is made of high-strength Q355B steel, which is formed by integral welding and precision heat treatment. This design not only enhances the overall rigidity and load-bearing capacity of the crane but also effectively resists the impact force generated during material grabbing. The crane’s running mechanism adopts heavy-duty wheels and high-precision reducers, with strong wear resistance and stable operation. In addition, all key components (such as motors, reducers, and grab cylinders) are selected from well-known international brands, ensuring the reliability and durability of the entire machine. The crane can work normally in harsh environments such as high dust, high temperature, and humidity, which is suitable for the working conditions of ore yards, coal-fired power plants, and slag treatment workshops.

3. Comprehensive Safety Protection System

Safety is the top priority of heavy lifting equipment. Our grab overhead crane is equipped with a multi-layer safety protection system to eliminate potential risks during operation. It includes overload protection (when the load exceeds the rated capacity, the system automatically cuts off the lifting circuit and issues an alarm), lifting height limit (prevents the grab from colliding with the crane beam), trolley travel limit (avoids collision with the end beam), and emergency stop device (supports emergency shutdown at any time in case of abnormal conditions). In addition, the electrical system adopts waterproof and dustproof design, and the operation platform is equipped with a safety guardrail and anti-skid pedals, fully ensuring the safety of operators and equipment.

4. Intelligent and Humanized Operation

The crane is equipped with an intelligent control system that supports both ground remote control and cab operation. The remote control adopts a wireless frequency hopping technology, with a control distance of up to 100 meters, allowing operators to stand in a safe area to complete all operations, avoiding direct contact with dusty and harsh working environments. The cab is designed with a wide field of vision, equipped with air conditioning and shock absorption seats, providing a comfortable operating environment. The control panel is simple and intuitive, with clear indicator lights and operation buttons, which is easy to learn and operate, reducing the difficulty of operator training. At the same time, the system can automatically record working data (such as working hours, load times, and fault information), which is convenient for equipment maintenance and management.

Application Scenarios: Tailored for Bulk Material Handling

• 1. Mine Industry: Used for lifting and transferring ore (iron ore, copper ore, coal ore, etc.) from the mining area to the crushing workshop or storage yard. The heavy duty grab overhead crane can adapt to the uneven terrain and dusty environment of the mine, realizing efficient and continuous ore handling.
• 2. Power Plant: Responsible for the transportation of coal from the coal yard to the boiler room. The electric grab overhead crane with anti-stick grab can effectively handle wet coal, ensuring the stable supply of fuel for the power plant and improving the efficiency of power generation.
• 3. Cement Factory: Used for handling raw materials such as sand, limestone, and clay, as well as finished cement clinker. The crane’s precise positioning function ensures that materials are accurately placed into the corresponding silos or production equipment, ensuring the smooth progress of the cement production process.
• 4. Metallurgical Industry: Used for transferring slag generated during steelmaking and ironmaking processes to the slag yard. The high-temperature resistant grab and durable crane structure can withstand the high-temperature environment around the metallurgical furnace, ensuring safe and reliable slag handling.
• 5. Port and Wharf: Responsible for the loading and unloading of bulk materials such as ore, coal, and sand between ships and warehouses. The large-tonnage bulk material grab overhead crane can complete the loading and unloading of large ships efficiently, improving the throughput of the port.
