BMH Explosion-Proof Electric Hoist Gantry Crane
Move equipment along an outdoor or semi-outdoor rail runway where the operating area requires explosion-protected lifting equipment. The BMH uses an explosion-proof electric hoist and hook; the hazardous-area classification, lifting duty and site layout must be specified together.
Start with the classified area and the load path.
BMH fits a project requiring hook lifting on ground rails with an explosion-protected hoist and matched electrical equipment.
Define the operating zone and the heaviest complete suspended load.
Provide both rail centres, travel length and any outside-span lift.
Check the medium, group, temperature class and control location.
Specify the BMH configuration that will be quoted.
The manufacturer identifies BMH as an A3 explosion-proof electric-hoist gantry crane. Rated load, span and lift must be matched to the site and stated on the project drawing.
| Parameter | Published or project selection | Procurement check |
|---|---|---|
| Model / type-test identification | BMH / explosion-proof gantry crane | Request a type-test record matching the offered crane and nameplate. |
| Lifting system | Explosion-proof electric hoist with hook | Match hoist, travel drives, controls and accessories to the approved area classification. |
| Published working class | A3 | Confirm the actual load spectrum and starts per hour for the project. |
| Span and runway | Two ground-supported rail lines; dimensions by site | Send rail-centre distance, travel length, ground levels and required hook coverage. |
| Rated load and lifting height | Project-selected | Include the item, rigging and hook equipment; give pickup and set-down elevations. |
| Cantilever | Optional | State left/right reach and the rated lifting case for each overhang. |
| Control | Cab, ground or remote arrangement | Agree the safe operating position, visibility and emergency-stop layout. |
| Explosion-protection basis | Defined from the classified area | Provide gas or dust medium, zone, group, temperature class and required standard. |
| Civil and outdoor load cases | Calculated for the final crane | Request wheel reactions, rail/foundation data and wind or corrosion requirements. |
Size the crane and its protection as one system.
For BMH, the mechanical arrangement and explosion-protection package must refer to the same approved operating zone. Supply the site plan and classification schedule with the enquiry.
Load and cycleGive complete suspended mass, lifts per hour, shifts and peak-load frequency.
RunwayMark rail centres, travel distance, hook approaches, cantilever and foundation limits.
HazardState the medium, zone, group, temperature class and applicable destination standard.
EnvironmentDefine wind, rain, corrosion, ambient temperature and power supply.
Request the finished wheel-load schedule and the protection equipment list with the offer.
Compare complete BMH offers, not just crane capacity.
Use one approved site layout and one hazardous-area specification when comparing technical and commercial offers.
Request rated load, span, lift, wheel reactions, area classification and matching component designations.
List the hoist, drives, electrical enclosure, control devices, travel system and required safety functions.
Agree factory inspection, dispatch, freight, erection, site acceptance and operator documentation.
Resolve the hazardous-area details before ordering.
These checks keep the quoted crane, installed protection and operating duty aligned.
Is BMH a double-girder gantry crane?
BMH identifies an explosion-proof electric-hoist gantry family. The bridge arrangement must be confirmed on the project drawing; do not infer a double-girder layout from the model code.
Can the hoist alone make a gantry explosion-proof?
No. The required classification applies to the complete electrical and mechanical arrangement, including drives, controls and accessories.
Are rated load and span fixed for every BMH?
No fixed BMH capacity–span schedule is published for this page. Request a matched drawing and rated configuration for your site.
What must the order specify?
Include the classified medium and zone, complete load, duty, rail layout, environmental conditions, protection documents, tests and dispatch milestone.
Send your BMH project brief.
Share the area classification, lifting task, complete load, span, lift, runway length, cantilever, duty, site conditions, power and destination. Request a BMH drawing and model-specific protection schedule.
