BMH Explosion-Proof Electric Hoist Gantry Crane
For buyers who need a rail-mounted gantry crane with an explosion-proof electric hoist, optional outside-span cantilever and a project-specific hazardous-area configuration.
Henan Mine Crane BMH explosion-proof electric hoist gantry crane showing the gantry structure, rail-mounted legs and lifting arrangement.
The BMH explosion-proof electric hoist gantry crane is developed from an electric-hoist gantry-crane platform and uses an explosion-proof electric hoist as the lifting mechanism. It runs on ground rails through two gantry legs and provides vertical lifting, cross travel and long travel.
The source states that the crane is designed according to national explosion-proof requirements, but it does not publish one universal explosion-protection grade. For procurement, the hazardous-area classification, gas or dust medium, temperature requirement and applicable project standard must therefore be defined before the final electrical and mechanical configuration is selected.

Product Overview
The source describes the BMH as an explosion-proof electric-hoist gantry crane with ground-rail travel, hook lifting and optional cantilever coverage. The crane is intended for intermittent, repetitive loading, unloading and material or equipment transfer.
A procurement decision should be based on two requirement sets at the same time: the lifting requirement and the hazardous-area requirement. Capacity, span and lifting height determine the mechanical crane; the hazardous-area specification determines the explosion-protected components and protection concept.
The source does not publish a fixed capacity range, span range, explosion grade, gas group, dust group or temperature class. These values should not be copied from another crane and should instead be written into the project technical specification.
Why Choose the BMH Explosion-Proof Gantry Crane?
Explosion-Proof Electric Hoist
The lifting mechanism is specifically described by the source as an explosion-proof electric hoist.
Ground-Rail Gantry Layout
Useful where a free-standing crane is preferred instead of an overhead building runway.
Optional Cantilever
The source allows an outside-leg cantilever for transferring loads from inside the span to positions outside the rail line.
Multiple Control Modes
Cab, ground and remote operation are source-listed, allowing the operator method to be selected around visibility and hazardous-area procedures.
Lightweight / Simple Structure
The source highlights simple construction, low self-weight, easy installation and maintenance, lower cost and lower foundation demand.
Compact Gantry Travel Drive
The source states that the travel mechanism uses a vertical gearbox arrangement to reduce occupied space, with a protective guardrail.

How to Select the Right BMH Explosion-Proof Gantry Crane
1. Start with the Hazardous-Area Specification
Provide the approved plant classification and hazardous medium before selecting explosion-protected components.
2. Define Capacity Correctly
Include the load plus rigging, lifting beam or any permanent below-the-hook device.
3. Confirm Span and Rail Layout
Provide the ground-rail center distance, total travel length and rail / foundation drawing.
4. Define Hook Height
State the actual required hook elevation and any pits, platforms, trucks or equipment below the crane.
5. Decide Whether a Cantilever Is Needed
Only add outside-span reach where the process needs truck loading, storage or transfer beyond the rail line.
6. Select the Control Method
Choose cab, ground or remote operation based on visibility, operator exposure and plant hazardous-area procedures.
7. Define the Outdoor Environment
If outdoors, provide wind, rain, dust, corrosion, temperature and anchoring / rail-clamp requirements.
Explosion-Proof Specification: What Buyers Must Confirm
| Hazardous-Area Classification |
Provide the approved classification used by the project / plant. |
| Hazardous Medium |
Identify gas, vapor, combustible dust or other classified medium. |
| Group / Temperature Requirement |
Provide the group and temperature requirement where applicable. |
| Applicable Standard |
State the project, national or local explosion-protection standard that controls acceptance. |
| Equipment Boundary |
Define which crane mechanisms and electrical components are inside the classified area. |
| Environmental Conditions |
Temperature, humidity, corrosion, dust and outdoor exposure can affect final equipment selection. |
| Acceptance Documents |
Define certificates, tests, inspection records and site acceptance required by the buyer. |
Procurement note: The source confirms an explosion-proof gantry-crane design and model BMH, but does not publish one universal explosion-protection grade. The final grade must match the buyer's approved hazardous-area specification.
Cantilever & Rail Layout: What Buyers Should Define
| Clear Span |
Distance between the ground-rail centerlines. |
| Cantilever Length |
Required hook reach outside each leg / rail line. |
| Runway Length |
Total gantry travel distance along the site. |
| Rail Elevation |
Important for checking crane geometry and hook height. |
| Foundation / Embedded Rail |
Provide civil and rail details so wheel loads and anchoring can be reviewed. |
| Outside-Span Load Position |
Show trucks, process equipment or storage locations served by the cantilever. |
Safety & Control: What Buyers Should Confirm
• Rated capacity and overload-protection requirements
• Hoisting upper / lower limits and gantry / trolley travel limits
• Brake and emergency-stop requirements
• Explosion-protected electrical components required by the approved classification
• Rail-end stops, buffers and anti-collision requirements
• Outdoor anchoring / rail clamps or wind protection where required
• Cab, ground or remote operator control and visibility
• Factory / site load tests and explosion-protection acceptance documentation
Installation & Maintenance
Before manufacture and installation, confirm rail center distance, runway length, rail elevation, foundation / embedded-rail condition, available lifting height, cantilever clearance, electrical supply and hazardous-area boundary. Outdoor sites should also provide design wind and operating-environment data.
Maintenance should follow the final supplied manual and the plant's hazardous-area procedures. Routine inspection should cover the electric hoist, ropes, hook, brakes, wheels, travel reducers, rail condition, limits, fasteners and all explosion-protected electrical components. Any maintenance action that affects explosion protection should follow the approved plant procedure.

Frequently Asked Questions
What is the source-stated working duty of the BMH crane?
The source page states working class A3.
What explosion-proof grade does the BMH gantry crane use?
The source page does not publish one universal grade. The final configuration must be selected from the buyer's approved hazardous-area classification and applicable standard.
Can the BMH gantry crane have a cantilever?
Yes. The source states that the legs can include an outside cantilever for transferring loads beyond the span, or the crane can be supplied without it.
What operator-control methods are available?
The source lists cab, ground and remote operation.
Why is the foundation drawing needed?
The crane travels on ground rails. Final wheel loads, rail support and civil works need to be checked against the project-specific crane configuration.
What information is most important for an accurate quotation?
Hazardous-area data, capacity, span, lifting height, runway length, cantilever requirement, rail/foundation drawing, operating environment and control method.
