Industrial Overhead Crane

The industrial overhead crane is a bridge-type lifting machine that spans a workshop bay on elevated runways, moving loads horizontally, laterally, and vertically across the full working area — handling 5–320 tons across spans of 10–35 m. It suits steel mills, automotive assembly plants, and heavy equipment manufacturing facilities. Each unit carries CE certification under Machinery Directive 2006/42/EC and conforms to ISO 9001:2015.

What Is An Industrial Overhead Crane?

An industrial overhead crane moves heavy loads across a full three-dimensional workspace — along the bridge, across the bay, and vertically through the hoist. Factory workshops, port terminals, and steel mills all depend on this equipment for safe, repeatable material transfer.

Dafang supplies seven overhead crane types, each matched to a specific working environment and duty class. As a result, buyers avoid costly over-specification and gain equipment that performs reliably over its full design life. Every unit carries CE certification under Machinery Directive 2006/42/EC and conforms to ISO 9001:2015.

Industrial Overhead Crane Types: Selection Guide

Three questions drive the right industrial overhead crane selection choice: What is the material? What is the environment? What duty class does the application require?

Type	Photo	Key Application	Duty Class	Distinguishing Feature
Electric Hoist Overhead Crane (LH/NLH)		General workshop hoisting	A3–A5	Compact, cost-effective, fast to install
Explosion-Proof Crane (QB)		Petrochemical, mining, flour mills	A5–A6	Ex d / Ex ia; GB 3836 / ATEX certified
Metallurgical Overhead Crane (QDY)		Steel mills, foundries, ladle bays	A7–A8	Dual braking, thermal insulation, tilt function
Insulated Overhead Crane (QY)		Aluminium electrolysis, electroplating	A5–A6	Full-unit or component-level insulation
Electromagnetic Overhead Crane (QC/QCL)		Scrap steel, ingots, steel plate	A6–A7	Electromagnet lifter; no slings required
Grab Bucket Overhead Crane (QZ)		Coal, ore, bulk waste	A6–A7	Double-flap Clamshell or Multi-petal hydraulic orange-peel grab integrated
Power Station Overhead Crane		Reactor equipment handling	Special based on conditiions	Redundant systems; seismic-rated design

Duty class per ISO 4301. A7/A8 denotes heavy and very heavy continuous-duty operation. Dafang provides duty class calculation support on request.

Key Engineering Features of Industrial Cranes

Industrial overhead cranes have 6 main engineering features across Performance, operating system, and exquisite design:

• Lifting capacity up to 320 tons — covers large-scale machinery, heavy moulds, and bulk loads across all major industries.
• Full-bay working coverage — bridge travel, trolley traverse, and vertical hoist together eliminate dead zones across the entire workshop footprint.
• Inverter-controlled drives — smooth start/stop reduces mechanical stress, extends component life, and enables precise load positioning.
• PLC automation ready — supports pendant, wireless remote, operator cabin, and fully automated control configurations.
• Type-specific safety systems — dual braking for metallurgical cranes, Ex d/Ex ia for explosion-proof models, full insulation for electrolytic environments.
• Thermal and corrosion protection — hot-dip galvanised or epoxy-coated structures; thermally insulated cables and cab for high-temperature duty.

Which Industry Can Industrial Overhead Crane Apply for?

Dafang clients apply Industrial overhead cranes across sectors like manufacturing, steel mills, mining, processing, logistics transfer centers, nuclear power stations:

• Steel and metallurgy — ladle, tong, and charging cranes for molten metal and hot ingots; A7/A8 duty class as standard.
• Petrochemical and mining — Ex d IIB T4 or Ex ia explosion-proof cranes, certified to GB 3836 and ATEX Directive 2014/34/EU.
• Automotive manufacturing — press-line tooling, body-in-white assembly, and sub-assembly transfer; typically A5/A6 duty.
• Port and logistics — QZ grab bucket cranes and electromagnetic cranes for high-volume bulk loading and unloading.
• Aluminium electrolysis and electroplating — insulated cranes prevent electric shock in high-current, corrosive environments.
• Nuclear and specialised facilities — redundant systems, seismic-rated design, and full regulatory compliance for reactor equipment handling.
