Explosion Proof Chain Hoist
Explosion Proof Chain Block, Spark Proof Manual Chain Block
Explosion-proof chain hoist (fully enclosed)In addition to being used alone, HBSQ-F explosion-proof chain hoists can also be assembled with electric hoists, chain drives or electric trolleys, suspended on the ceiling of buildings or beams of cranes, and can also be used with monorail trolleys to achieve left and right The function of walking to lift heavy objects, the installation and disassembly of explosion-proof chain hoists are very convenient, safe and fast!
The explosion-proof chain hoist is made of aluminum bronze and beryllium bronze as the blank, and the shell of the chain hoist is made of H62 copper alloy material. The force-bearing friction parts include the lifting wheel, hand chain wheel, wall plate, hook, gear and gear shaft that constitute the chain hoist. Aluminum bronze and beryllium bronze alloy materials are used. The product is safe and reliable, the design is advanced, and the chain wear will not cause adverse reactions such as sparks and explosions!

Application of spark proof manual chain block
It can be widely used in petroleum, petrochemical, gas station, oil depot, gas production, chemical industry, mining, electronics, railway, shipbuilding and other industries.
HBSQ-ZHF explosion-proof low headroom chain hoist is a newly developed product of our factory, as long as it is divided into B/C grade explosion-proof products.
HBSQ-explosion-proof chain hoist (combined type) is a newly developed product of our factory, as long as it is divided into B/C grade explosion-proof products.
- Class B HBSQ-ZH explosion-proof chain hoist (combination type) is suitable for: petroleum, petrochemical. Gas station, oil depot, chemical industry, military industry, electric power, mining, electronics, railway and other occasions. (Note: Do not operate in flammable gas or environments with high requirements for explosion-proof grades). Class B explosion-proof rubbing against each other will not produce sparks during operation, which can effectively prevent fire accidents.
- Class C HBSQ-ZH type explosion-proof chain hoist (combination type) is suitable for: petroleum, petrochemical, gas station, oil depot, gas production, chemical industry, military industry, electric power, mining, electronics, railway, etc. potential fire and explosion and leisurely gas in a hazardous environment. No sparks will be generated during friction work, effectively preventing potential fire accidents.
Explosion proof manual travelling trolley
GCBL type explosion-proof hand-pulled trolley / travelling trolley / monorail trolley is a new developed explosion-proof hand-pulled trolley . It is simple in structure, easy to operate, light and light as a matching hoisting machine for dispatching and transporting. It is driven by a bracelet to lift goods. It can be matched with lifting equipment such as chain hoists or electric chain hoists to form a hoisting and transporting trolley. On the lower wing edge of the I-beam runway with a radius of curvature, it is installed on the monorail overhead transportation line of straight or curved roads or on manual single girder, bridge, and cantilever cranes!

Explosion Proof Chain Hoist FAQs
Explore the most common questions buyers ask when selecting explosion proof chain hoists, including lifting capacity, hazardous environment suitability, spark-proof materials, and practical industrial applications across petrochemical, mining, and manufacturing workshops.
What is an explosion proof chain hoist used for?
It is used for safe manual lifting in hazardous environments where sparks could cause fire or explosion.
- Ideal for oil, gas, and chemical plants
- Prevents sparks during friction or impact
- Suitable for Zone 1 and Zone 2 hazardous areas
- Common for maintenance and repair lifting tasks
What lifting capacity should I choose?
Choose a hoist with at least 25–30% higher capacity than your actual load.
- 0.5–2 ton for light maintenance work
- 3–5 ton for pumps and machinery
- 10–20 ton for heavy industrial equipment
- Safety margin improves durability and reliability
What is the difference between Class B and Class C?
Class C provides higher explosion protection compared to Class B.
- Class B for general petroleum environments
- Class C for high-risk explosive gas zones
- Both prevent spark generation during operation
- Selection depends on hazard classification of site
Can the hoist move along a beam or track?
Yes, it can move horizontally when combined with a manual traveling trolley.
- Works on I-beams and monorail systems
- Supports straight and curved track movement
- Common in overhead crane setups
- Useful for positioning loads across work areas
When should I choose a low headroom design?
Choose it when working in areas with limited ceiling height.
- Maximizes lifting height in confined spaces
- Ideal for workshops under 6–8 meters
- Improves lifting efficiency in tight installations
- Common in indoor plants and equipment rooms
What materials make it spark-proof?
It uses aluminum bronze and beryllium bronze components to prevent sparks.
- Hooks and gears made from anti-spark alloys
- H62 copper alloy housing for durability
- Resistant to corrosion and impact
- Safe for flammable gas and dust environments
Is manual operation safe compared to electric hoists?
Yes, manual hoists are safer because they eliminate electrical ignition risks.
- No electrical components involved
- Reliable for hazardous environments
- Suitable for maintenance and emergency lifting
- Lower failure risk compared to electric systems
What industries use explosion proof chain hoists?
They are widely used in oil, gas, chemical, mining, and power industries.
- Petrochemical plants and refineries
- Gas stations and fuel depots
- Mining and dust-explosion environments
- Shipbuilding and electronics manufacturing
What loads are typically handled in workshops?
Most industrial applications handle loads between 1 ton and 10 tons.
- 1–3 ton for valves and pipelines
- 3–5 ton for pumps and motors
- 5–10 ton for heavy equipment maintenance
- Load type determines hoist configuration
What maintenance is required?
Regular inspection, lubrication, and cleaning are required for safe operation.
- Inspect chain wear and elongation
- Check hooks and gears for deformation
- Use non-sparking lubricants
- Clean after exposure to corrosive environments
