Bridge cranes are essential in industrial operations, but specialized environments demand custom solutions. Metallurgical, explosion-proof, and insulated bridge cranes are engineered for unique challenges. Metallurgical cranes handle extreme heat and heavy loads in metal processing, explosion-proof cranes ensure safety in volatile atmospheres, and insulated cranes prevent electrical hazards in electrolytic processes. This guide explores their functions, applications, and operational efficiencies.

Metallurgical Bridge Cranes

A metallurgical bridge crane (code: Q10402; standard: GB/T 14405-2011) is designed for metal smelting, casting, rolling, and hot processing. It integrates directly into production lines, withstanding high temperatures and corrosive environments. Key variants include:

  1. Charging Crane (JB/T 7688.3-1995): Feeds materials into furnaces using buckets or troughs.

  2. Forging Crane (JB/T 7688.3-2008): Lifts and flips heavy forgings with shock-absorbing mechanisms.

  1. Quenching Crane (JB/T 7688.6-2008): Rapidly immerses hot workpieces into quenching fluids.


  1. Claw Crane (JB/T 7688.7-2008): Moves billets with grapples or electromagnetic attachments.

  1. Soaking Pit Crane (JB/T 7688.8-2015): Loads materials into soaking pits using specialized clamps.


How Does This Crane Work?
These cranes use heat-resistant components, reinforced structures, and precise controls to manage heavy, hot loads. For example, ladle cranes employ dual braking systems to prevent accidental spills.

Explosion-Proof Bridge Cranes

An explosion-proof bridge crane (code: Q10403; standard: JB/T 5897-2014) operates safely in explosive gas or dust environments. It features spark-proof materials and enclosed electrical parts. A related type, the cleanroom bridge crane (JB/T 14201-2022), minimizes contamination in sterile settings like pharmaceutical labs.

How Does This Crane Work?
Explosion-proof cranes use sealed motors, non-sparking alloys, and pressurized enclosures to isolate ignition sources. Cleanroom cranes include smooth surfaces and HEPA filters to maintain air purity.

Insulated Bridge Cranes

An insulated bridge crane (code: Q10404; standard: JB/T 8907-2013) prevents electrical conduction in electrolytic facilities (e.g., aluminum, copper smelting). Key models include:

  1. Pot Tendering Machine (PTM) (YS/T 7-2020): Services electrolytic cells in aluminum production.

How Does This Crane Work?
Insulated cranes feature non-conductive coatings, ceramic isolators, and grounded systems to block current flow. PTMs, for instance, use modular tools for tapping and anode changing.
