Content Quick Link
Slag crane or slag handling crane is an overhead travelling grab crane for slag waste handling in steel mills and furnaces. The grab overhead travelling crane is adopted for slag handling and management through all the processes of slag distribution along main conveyor lines when the slag is sorted through the slag bunker, grabbed, transported and loaded onto trucks.
With process crane designs, our industrial overhead cranes offer an effective slag handling crane solution for your particular application with reliability and high performances.

Reliable slag handling cranes for harsh environment
A dusty and humid application environment is very demanding for an overhead travelling cranes. For slag handling, the slag handling cranes and hoisting trolley are required to withstand harsh environments and highly abrasive loads. The industrial overhead travelling cranes are required through the entire process of slag handling which starts with hot slag clearing, transportation, sorting and finally recycling or disposal. Slag handling overhead travelling cranes are designed and implemented based on customer lifting requirements and specific local conditions.
Overhead Slag Crane with Grab Bucket
Typical Lifting Capacity: 5–30 tons

Features: Equipped with a heavy-duty grab bucket for precise slag collection and transfer, designed for continuous operation in high-temperature environments.
Overhead Slag Handling Crane
Typical Lifting Capacity: 10–50 tons
Applications: Moving large volumes of slag from furnace to slag yard, feeding into processing lines.
Industrial Sectors: Steel plants, ironworks, power plants with slag byproducts.
Features: High-capacity hoist with robust structure, capable of handling abrasive and heavy slag loads efficiently.
Heavy-Duty Grab Bucket Crane for Slag Handling
Typical Lifting Capacity: 20–100 tons
Applications: Transferring slag from furnaces, loading slag into trucks or conveyors, recycling slag for construction use.
Industrial Sectors: Steel mills, foundries, cement plants, recycling operations.
Features: Advanced grab bucket design ensures precise handling, minimizes spillage, and improves operational safety.
The grab overhead travelling crane is adopted to distribute slag along the conveyor line to the other areas in the slag bunker 24 hours a day.Usually, there are two slag handling crane installed to ensure the efficiency of processing line, the primary overhead travelling crane undertakes the main handling tasks when the other slag crane is being serviced.
Crane grab with process design for efficient slag handling
Another more critical duty of the slag handling crane is grabbing the slags into trucks. The handling of the ferrous, separated from the slag has higher requirements for the crane grabs which requires clamshell grabs with special teeth or the fully closed orange peel-type grabs to help achieve better penetration and solid handling.

Slag Handling Cranes FAQ
Frequently asked questions about overhead slag cranes and grab bucket cranes, including capacities, applications, industrial environments, and safety features.
What is the typical lifting capacity of a slag handling crane with a grab bucket?
Slag handling cranes usually lift between 5 and 100 tons depending on the model and industrial requirements.
- Small to medium cranes handle 5–30 tons, ideal for standard steel mill slag removal.
- Heavy-duty cranes lift 50–100 tons for large-scale steel plants or foundries.
- Capacity selection depends on the volume and weight of slag produced in your operation.
- Grab bucket size and hoist speed affect material transfer efficiency.
In which industrial sectors are slag cranes most commonly used?
Slag cranes are primarily used in steel mills, foundries, metallurgical plants, cement factories, and recycling operations.
- Steel and iron plants require continuous slag removal from furnaces and casting areas.
- Foundries use grab bucket cranes for molten or solid slag handling.
- Cement plants and recycling yards handle slag as raw material for construction applications.
- These cranes improve productivity and safety in high-temperature or abrasive environments.
What types of applications are typical for grab bucket slag cranes?
Grab bucket slag cranes are used for transferring slag from furnaces, loading slag into trucks or conveyors, and recycling slag.
- Furnace-to-slag yard transfer for disposal or processing.
- Feeding slag into crushing or sorting lines for reuse.
- Handling high-temperature slag safely without manual labor.
- Precision grab designs minimize spillage and improve workflow in busy workshops.
What environmental or workshop conditions do slag cranes operate in?
Slag cranes operate in high-temperature, dusty, and abrasive environments typical of steel mills and foundries.
- Designed to withstand continuous exposure to molten slag and heavy debris.
- Heavy-duty steel structures and heat-resistant components ensure long-term reliability.
- Suitable for indoor and outdoor steel plant yards, with corrosion-resistant options available.
- Some models include dust control or enclosed operator cabins for safety.
How do I choose the right grab bucket size for my slag crane?
The grab bucket size should match the average slag load per lift and your production rate.
- Small grabs (0.5–1 m³) are suited for moderate slag removal in small workshops.
- Medium grabs (1–3 m³) handle most steel plant slag operations efficiently.
- Large grabs (5–10 m³) are for high-volume steel mills or heavy-duty metallurgical plants.
- Consider material density, lift frequency, and crane hoist speed when sizing the bucket.
Can these cranes handle other materials besides slag?
Yes, grab bucket cranes can also handle scrap metal, molten metal byproducts, and bulk materials.
- Multi-purpose cranes increase operational flexibility.
- Suitable for foundries needing to move scrap metal for recycling.
- Must consider temperature, weight, and abrasiveness of alternate materials.
- Proper attachments and control systems are recommended for safe handling.
What safety features should I look for in a slag crane?
Safety features include overload protection, heat-resistant grab buckets, operator cabins, and emergency stop systems.
- Overload protection prevents structural damage and accidents.
- Heat-resistant materials protect critical components from molten slag.
- Enclosed operator cabins reduce exposure to high temperatures and dust.
- Anti-sway and precise control systems enhance safety in industrial workshops.
