PRODUCTS & CASES

Manufactured in strict accordance with GB3836.1-2000 and GB3836.2-2000 national explosion-proof standards, this explosion-proof electric hoist adopts certified explosion-proof design for its driving motor and all matched electrical components. For units with ExdII CT4 explosion-proof grade, the whole travelling mechanism receives dedicated spark-proof processing, eliminating ignition risks and supporting stable safe lifting in flammable and explosive hazardous zones.

Product Description
           This series explosion-proof electric hoist covers two mainstream explosion-proof grades: ExdII BT4 and ExdII CT4. It delivers steady, secure lifting performance for high-risk industrial scenarios including chemical processing plants, oilfield operation zones and natural gas stations.

           The hoist can be independently installed on fixed overhead suspension rails inside workshops. Meanwhile, it features strong compatibility and can be matched with complete sets of explosion-proof crane equipment, such as LXB explosion-proof underhung single girder cranes, LB explosion-proof single girder overhead cranes and explosion-proof double girder crane systems.

           Besides standard models, Weihua launches the upgraded NR series explosion-proof electric hoist with optimized structural layout, upgraded safety configurations and enhanced overall working performance for stricter hazardous working conditions.

• Fully compliant with GB3836.1-2000 and GB3836.2-2000 explosion-proof technical specifications

• Two optional explosion-proof grades: ExdII BT4 and ExdII CT4 to match different risk levels

• Complete spark-proof treatment on travelling components for ExdII CT4 high-risk environments

• Upgraded NR series explosion-proof hoist available as an optimized alternative

Weihua offers fully personalized explosion-proof electric hoist solutions tailored for various hazardous industrial sites. We can flexibly customize core parameters including lifting tonnage, lifting height, wire rope length and operating speed. We also support grade upgrading between ExdII BT4 and ExdII CT4, as well as special anti-corrosion structural treatment for damp coastal chemical plants. All customized units strictly follow explosion-proof standards to guarantee zero hidden dangers during long-cycle heavy lifting.

Optional Configurations

• Standard type and upgraded NR series explosion-proof hoist two options

• Wired explosion-proof pendant control or explosion-proof wireless remote control

• Variable frequency driving system for stable low-shock lifting and traversing

• Complete multi-layer safety protection: overload limit, upper/lower travel limit and emergency stop

• Reinforced sealed anti-corrosion structure for high-humidity chemical and coastal environments

Our professional R&D and engineering team strictly controls every explosion-proof link of the hoist. All finished products pass rigorous explosion-proof testing, delivering highly reliable lifting equipment for chemical factories, oil & gas stations and all other explosive hazardous production workshops.
