Henan Mine Crane · Steel Production Lifting Systems
Steel Mill and Foundry Cranes
Henan Mine Crane engineers steel mill and foundry cranes for raw-material handling, furnace charging, molten-metal transfer, continuous casting, hot rolling, slab and billet movement, coil and plate storage, scrap handling and plant maintenance. Each crane is matched to its process load, attachment, heat exposure, production cycle, runway and required safe-failure response.
A complete steelworks normally requires several crane types rather than one universal design. Ladle cranes prioritize molten-metal safety; magnetic and clamp cranes protect finished material; grab cranes handle bulk feed and slag; maintenance cranes provide controlled access to production equipment. The plant crane schedule must therefore be developed bay by bay and duty by duty.

Steel Mill and Foundry Crane Systems by Process Area
Steel mill cranes are process-specific overhead lifting systems used throughout ironmaking, steelmaking, casting, rolling, storage and maintenance. Foundry cranes form the high-risk molten-metal segment of this larger equipment family. The selected structure, hoisting mechanism, attachment, control method and protection package must correspond to the exact material and production step.
Direct ladle handling cannot be specified in the same manner as billet storage or general maintenance. Likewise, a magnetic crane intended for flat plate requires different pickup geometry and loss-of-power protection from a grab crane moving slag or scrap. A dependable procurement package separates each duty before equipment selection begins.
Raw Materials and Scrap
Grab, magnet and dual-purpose cranes move scrap, ore, coke, flux, slag and other bulk or ferrous material.
Melting and Pouring
Charging, ladle and casting cranes support furnace feed, molten-metal transfer, treatment and controlled pouring.
Casting and Rolling
Slab, billet, bloom, coil and plate cranes transfer hot and finished material between process and storage zones.
Maintenance and Assembly
Heavy-duty hook cranes provide planned access to furnaces, rolls, motors, gearboxes, ladle cars and production equipment.
Selection Considerations
01 / MATERIAL
Load Form and Temperature
Identify molten metal, scrap, bulk feed, slag, slab, billet, coil, plate, mould or machinery; record normal and maximum temperature at pickup and travel.
02 / LOAD
Complete Suspended Mass
Include payload, ladle or container, refractory lining, magnet, grab, clamp, lifting beam, rigging and all allowances required by the governing design basis.
03 / PROCESS
Production Route and Cycle
Define pickup and set-down stations, travel distances, lifts per hour, near-capacity lifts, shift pattern, production interlocks and required cycle time.
04 / ATTACHMENT
Pickup and Release Method
Confirm trunnion, hook, magnet, clamp, tong, C-hook, grab or beam interface, including rotation, opening, closing, power and safe-release requirements.
05 / ENVIRONMENT
Heat, Dust, Fumes and Splash
Record ambient and radiant heat, conductive dust, scale, moisture, corrosive fumes, molten splash, outdoor exposure and enclosure requirements.
06 / SAFETY
Credible Failure Response
Establish the required response to power loss, brake fault, drive failure, overspeed, overload, attachment power loss, upper-limit activation and control interruption.
07 / RUNWAY
Building and Rail Interface
Verify span, lift, approaches, wheel loads, horizontal reactions, rail section, alignment, support capacity, thermal effects and erection access.
08 / PROJECT SCOPE
Controls, Standards and Supply Boundary
Define cabin, radio or automation, power supply, plant communication, governing standard, inspection plan, documentation, freight and installation responsibilities.
The crane name is not a complete specification. A magnetic plate crane, a ladle crane and a maintenance bridge crane can share the same rated capacity while requiring different duty classifications, attachments, brakes, controls, wheel loads and acceptance tests.
Compare Steel Mill and Foundry Crane Types
The preferred crane follows the production duty and handled material. This comparison provides an initial route from plant process to product family; final selection requires the complete operating and site data.
| Crane Type | Handled Material | Listed Product Range | Critical Selection Point |
|---|---|---|---|
| Double-Girder Foundry Crane | Molten iron or steel ladles | 50–150 t; 10–35 m span; A7–A8 | Complete ladle mass, trunnion interface, heat exposure and molten-metal safety basis |
| Four-Girder Casting Crane | Ultra-heavy ladles and foundry loads | 200/50–500/200 t; 10–40 m span; A7–A8 | Main and auxiliary trolley functions, torsional load cases and runway reactions |
| Metallurgical Bin Crane | Charge boxes and furnace feed | 5–50 t; 7.5–35 m span; A6–A7 | Box geometry, opening and tipping method, furnace clearance and dust protection |
| Rotating Magnetic Overhead Crane | Billets, plates, bars and long steel | 5+5–25+25 t; 10.5–31.5 m span; A6–A7 | Material magnetic properties, beam geometry, rotation, power-loss holding and stacking orientation |
| Slab Handling Crane | Hot or ambient slabs and billets | 20–150 t; 10–39 m span; A7–A8 | Material temperature, pickup face, clamp or magnet response and storage geometry |
| Grab Overhead Crane | Ore, coke, flux, slag and selected scrap | Project-configured | Bulk density, lump size, abrasiveness, grab volume, fill factor and discharge control |
| Quenching Crane | Hot components for heat treatment | Project-configured high-duty system | Immersion timing, lifting speed, emergency recovery and bath geometry |
| Double-Girder Maintenance Crane | Rolls, motors, gearboxes and plant equipment | Project-configured | Heaviest maintenance lift, access path, headroom, precision and planned usage |
The ranges above identify separate Henan Mine Crane product families and do not represent every possible capacity–span combination. Final values follow structural calculation, mechanism selection, runway limits and the approved technical specification.
Crane Coverage Across the Steel Production Process
Stockyard and Scrap Bay
Grab and magnetic cranes unload, sort, blend and feed scrap or bulk material. Crane capacity must include the attachment, and throughput calculations must use the actual grab fill factor or magnet pickup condition.
Melt Shop and Foundry
Bin cranes charge furnaces, while foundry and casting cranes lift ladles, transfer liquid metal and support pouring. Molten-metal duty requires a defined safety architecture and thermal protection rather than a general-purpose crane specification.
Continuous Casting and Rolling
Slab and billet cranes move material between casting machines, cooling areas, reheating furnaces, rolling lines and intermediate storage. Pickup geometry, material temperature and cycle time determine the attachment and control system.
Finishing and Dispatch
Magnetic beams, clamps, tongs and C-hooks handle plate, long steel and coils. Finished-material protection, rotation, stack height, warehouse management interfaces and safe holding during power loss become primary design inputs.
Load Attachments for Steel Mill and Foundry Cranes
The attachment is part of the lifting system, not an accessory selected after the crane. Its mass, geometry, power source, control logic and failure response affect crane capacity, headroom, stability and acceptance testing.
Ladle Beam or Gantry Hook
Engages ladle trunnions for molten-metal lifting. Trunnion diameter, centres, ladle envelope, seating and inspection access require confirmation.
Electromagnetic Beam
Lifts ferrous plate, billet, bar or scrap. Material grade, thickness, temperature, air gaps and safe holding after power loss govern selection.
Grab Bucket
Handles ore, coke, flux, slag and bulk scrap. Density, lump size, abrasiveness, moisture and target throughput define grab type and volume.
Clamp, Tong or C-Hook
Supports slab, billet, plate and coil handling. Contact pressure, surface protection, centre of gravity and loss-of-power behavior must be defined.
Engineering Requirements for Metallurgical Duty
Structural Load Cases
Girders, trolley frames, end carriages, wheels and runway interfaces are assessed for lifted load, attachment, dynamic effects, off-centre positions, skew forces and applicable thermal conditions.
Mechanism Duty
Motors, gearboxes, brakes, drums, ropes, sheaves, bearings and wheels are selected from starts, operating time, load spectrum, travel distances and production criticality.
Thermal and Environmental Protection
Heat shields, protected cables, metallurgical-duty motors, ventilated cabinets, insulated cabins, dust-resistant enclosures and temperature monitoring are applied where the measured exposure requires them.
Safe-Failure Architecture
Multiple brakes, redundant drives, drum brakes, backup power, magnet holding, limits, overload protection and emergency placement can be specified when required by risk and governing rules.
Motion and Positioning
Variable-frequency control, creep speed, anti-sway, encoders, coordinated drives and automatic positioning support stable ladle movement and repeatable material stacking.
Plant Integration
PLC and HMI systems can exchange task, position, load, alarm and status data with plant controls, warehouse systems or manufacturing execution systems under an agreed interface specification.
Safety functions must be specified by function, independence, setpoint, alarm, stop category, recovery method and verification test. A component name alone does not establish suitability for molten metal or continuous steel-production duty.
Steel Mill Crane Specification Schedule
A plant-wide inquiry should include a separate duty sheet for every crane. The schedule below identifies the minimum technical information required to compare proposals on the same basis.
| Specification Group | Required Information | Procurement Effect |
|---|---|---|

Steel Mill and Foundry Crane Price
Public international equipment listings indicate approximately US$8,000–US$50,000+ for basic steel-mill double-girder, hook, grab or magnetic overhead crane configurations. Market guidance for more specialized electromagnetic process cranes commonly reaches approximately US$25,000–US$95,000+.
New ladle and heavy foundry crane listings span approximately US$60,000 to more than US$2,000,000 per set. These figures are market-screening references, not fixed Henan Mine Crane prices. High-capacity four-girder, automated, slab, coil and complete installed systems require an engineered commercial proposal.
| Cost Package | Typical Inclusions | Principal Cost Drivers |
|---|---|---|
| Crane Equipment | Bridge, trolley, hoisting and travel mechanisms, cabin or controls, electrification and specified safety functions | Capacity, span, lift, duty, speeds, redundancy, heat exposure and automation |

Commercial comparisons must use the same load, attachment, span, lift, duty, safety architecture, heat protection, automation, runway boundary, documentation, delivery term and site-service scope. Equipment-only listings are not directly comparable with complete installed-system quotations.
Steel Mill and Foundry Crane FAQ
What cranes are used in a steel mill?
Common types include scrap and bulk-material grab cranes, charging cranes, ladle and casting cranes, slab and billet cranes, magnetic plate and bar cranes, coil-handling cranes, quenching cranes and general maintenance bridge cranes.
What is the difference between a steel mill crane and a foundry crane?
Steel mill crane is a broad term covering cranes throughout the production facility. A foundry crane is a specialized member of this family designed for molten-metal ladles, pouring and related high-temperature casting operations.
Can one crane handle scrap, ladles and finished steel?
A single crane should not be assumed suitable for all three duties. The attachments, load paths, working classes, heat exposure and required failure responses differ. Multi-purpose service requires explicit engineering and approval for every load case.
How is foundry crane capacity calculated?
Rated load includes molten metal, ladle shell and refractory lining, ladle beam or gantry hook, rigging and required design allowances. Liquid-metal mass by itself is not the complete suspended load.
Which working class is required?
Henan Mine Crane metallurgical product families are listed from A6 to A8. The final classification follows operating time, starts, load spectrum, cycle rate, process risk and the selected classification standard; rated capacity alone does not determine duty.
How are steel mill cranes protected from heat and dust?
Protection can include heat shields, heat-resistant cables and motors, ventilated or cooled cabinets, insulated cabins, protected brakes, dust-resistant enclosures and temperature monitoring. The package follows the measured ambient and radiant exposure.
What happens if power is lost during magnetic lifting?
The required response is established from the load and risk assessment. A magnetic system can include stored-energy holding, alarm, monitored power condition and a defined safe-placement procedure. Holding duration and test method must be specified.
Can steel mill cranes operate automatically?
Automatic task dispatch, positioning, anti-sway, collision avoidance, load tracking, inventory interfaces and remote monitoring can be integrated where the process layout, exclusion zones, communications and safety concept support automation.
How much do steel mill and foundry cranes cost?
Basic steel-mill crane listings commonly begin around US$8,000–US$50,000+, specialized magnetic systems can reach approximately US$25,000–US$95,000+, and listed heavy ladle and foundry equipment spans roughly US$60,000 to more than US$2,000,000 per set. Final cost requires a project specification.
What information is required for a quotation?
The RFQ should include process area, handled material, temperature, maximum and normal load, attachment, span, lift, runway length, operating cycle, required speeds, environment, control method, power supply, standards, inspection and delivery and installation scope.
