If you own a chemical, coating, grain & oil or metal dust processing factory, workshop safety must be your top priority. Ordinary overhead cranes produce electric sparks every time they start or stop. Once these sparks touch oil gas or flammable dust, it can easily trigger fires or explosions — and safety inspectors will immediately order you to stop production and rectify the equipment.
The Nucleon Explosion-proof Double-girder Bridge Crane is specially designed for high-risk workshops with flammable and explosive hazards. The entire machine adopts fully sealed, spark-free explosion-proof structures, completely eliminating potential safety risks at the source.
1. Core Safety Gap: Nucleon Explosion-proof Double-girder Crane vs Ordinary Standard Double-girder Crane
Ordinary Standard Double-girder Crane
Their motors, control cabinets, handles and limit switches are all ordinary civilian electrical parts. Sparks are unavoidable during startup, shutdown or circuit faults. They are only suitable for dry, safe machining workshops and warehouses with no flammable or explosive materials. Using them in chemical, dust or oil-gas workshops is strictly forbidden and will lead to catastrophic safety accidents.
We offer two mainstream explosion-proof grades: Exd II BT4 and Exd II CT4, which match different levels of hazardous substances. All models pass national official explosion-proof certification and fully meet safety inspection standards.

2. Working Conditions That Must Adopt Explosion-proof Double-girder Cranes
You must replace ordinary cranes with explosion-proof models if your workshop has any of the following conditions:
✅ Workshops producing or storing flammable and explosive liquids/gases such as paint, chemical solvents, gasoline, diesel and liquefied gas;
✅ Workshops processing or storing combustible dust such as aluminum powder, magnesium powder, coal dust and flour;
✅ Oil & gas supporting workshops, chemical raw material warehouses, hazardous goods assembly and sub-packaging workshops;
✅ Local safety supervision departments require lifting equipment with complete explosion-proof qualifications.
3. Key Selection Points to Avoid Safety Pitfalls
Match explosion-proof grade with actual medium
Exd II BT4: Perfect for regular workshops with paint, chemical solvents and common combustible dust.
Exd II CT4: A must for workshops with high-risk media like hydrogen and acetylene. Choosing the wrong grade will fail safety inspections and leave serious explosion risks.
Reject semi-explosion-proof modified cranes
Many cheap cranes on the market only replace the motor with an explosion-proof one, while keeping ordinary control cabinets, handles and limit parts. These machines still produce sparks and are unqualified for hazardous workshops. All Nucleon explosion-proof cranes adopt full-machine explosion-proof configuration with complete formal certification documents.
High working level for high-intensity workshops
Most chemical and dust workshops run 24 hours a day non-stop. Our cranes adopt thickened steel main beams with a minimum A6 working level, never deforming even under long-term heavy-load operation.
Custom anti-corrosion configuration for chemical workshops
Chemical substances are highly corrosive. We spray heavy-duty anti-corrosion coating on main beams and travelling wheels to effectively prevent rust and equipment aging.
4. Do Not Pursue Low Prices — Explosion-proof Cranes Have Strict Standards
Explosion-proof double-girder cranes cost 40%–100% more than ordinary models. The price gap is reasonable, as certified explosion-proof electrical parts and professional testing procedures cost much more.
Those ultra-cheap semi-explosion-proof cranes have no complete qualification certificates. They will get your factory shut down during safety spot checks. If any safety accident happens, your factory will bear full legal liability. All Nucleon explosion-proof cranes are fully certified and strictly tested before delivery, ensuring 100% safe and compliant operation.
5. Applicable Scenarios
Chemical plants, oil & gas supporting workshops, grain and flour processing factories, metal dust smelting workshops, hazardous material warehouses and paint spraying production workshops.
