LHB Explosion-proof electric hoist overhead cranes;are specialized lifting systems designed for hazardous environments where flammable gases, vapors, or dust may exist. These cranes integrate explosion-proof motors, electrical components, and safety mechanisms to prevent ignition sources in volatile conditions. Below is a detailed breakdown of their features, applications, and specifications:
Explosion-Proof Components:
Motors: Fully enclosed, spark-resistant motors (e.g., ExdII BT4/CT4 rated) with Class B/F insulation and IP44/IP54 protection.
Controls: Explosion-proof pendant controls, limit switches, and junction boxes.
Structural Safety: Spark-proof treatments on trolleys, gears, and brakes to prevent friction-induced sparks.
Lifting Capacity & Performance:
Capacity: 0.25–320 tons (standard models: 0.5–50 tons; heavy-duty up to 320 tons).
Lifting Speed: 0.8–8 m/min (dual-speed options for precision).
Span: 3–50 meters (customizable for industrial layouts).
Lifting Height: 3–100 meters (adjustable for vertical workflows).
Certifications & Standards:
Complies with ATEX, IECEx, FEM, and DIN standards.
Temperature classifications: T1–T6 (supports ambient temps from -25°C to +40°C).
Explosion-proof grades: ExdII BT4, ExdII CT4 (suitable for Zones 1/2).

| Ambient Conditions | -25°C to +40°C; humidity ≤85% |
Oil & Gas: Loading/unloading in refineries and offshore platforms.
Chemical Plants: Handling corrosive or flammable materials.
Mining: Transporting minerals in dust-laden environments.
Pharmaceuticals: Safe operations in solvent-heavy facilities.
Food Processing: Compliance with hygiene and safety in ethanol zones.
Motors: Cast aluminum enclosures to contain internal explosions; heat dissipation to prevent overheating.
Wiring: Rubber-sheathed copper cables with grounded cores; no exposed joints.
Brakes: Spark-resistant materials and heat-dissipating designs.
Control Systems: PLC automation with variable frequency drives (VFDs) for smooth acceleration/deceleration.

DJCRANES: For standardized BCD hoists with modular reducers (up to 50t).
Nante Crane: Custom solutions with advanced heat dissipation and T6 compliance.
Hoist & Winch: ATEX-certified cranes for extreme environments (up to 320t).
Finework Cranes: Compact HB/BMD hoists for corrosive/acidic settings.
Initial Cost: $15,000–$500,000+ (varies with capacity and certifications).
Maintenance: Regular inspection of gears, wiring, and explosion-proof seals; replace wire ropes every 1–2 years.
Yes, because the working condition are different, all our products are customized depending on detail requirement! So all your products will be specially designed by our engineers according to your workshop conditions.
Yes, all kinds of certification are available, if you have doubt, you can come to our factory and test it by yourself,or you can let some third-partied to do the inspection for you.
Yes, we have. But we only have the standard-sized products, if you need customized products, then it will take some time to manufacture it.
It depends on your products quantity and products data you given, but we will try our best to deliver your products as soon as possible.
We will sent you the detail installation manual or if you are needing, our installation engineers can come to your workshop to guide the installation.
You can come to our factory anytime when you are convenient. We will make arrangement to pick you up.
