Single Girder Overhead Crane Technical Parameters
How to Choose the Right Single Girder Overhead Crane?
To pick a proper single girder EOT crane, follow 7 steps: confirm lifting parameters → define duty class → judge special working environment → match hoist type → select auxiliary safety functions → check plant bearing structure → compare budget & factory qualification.
LD, HD, LB, LDY, LDZ, LX correspond to ordinary, low-headroom, explosion-proof, metallurgical, grab and suspension scenarios respectively.
Step 1: Confirm Lifting Technical Parameters
● Rated lifting capacity: Calculate the maximum weight of goods to be lifted, leave a 10%–20% safety margin, do not choose a crane with a capacity equal to the heaviest workpiece.
● Span of workshop: Measure center distance of two runway beams as standard span; HD supports max 31.5m, LX suspension is limited to 16m.
● Lifting height: Measured from the floor to the hook’s highest point. This determines the required wire rope drum size and impacts the factory’s vertical clearance.
● Lifting speed & travel speed: Simple warehouse, intermittent use: CD single speed fixed 8m/min, low cost; Mold assembly, precise fitting: MD dual speed (8/0.8 m/min) or HD full variable frequency.
Step 2: Confirm Working Duty Class
● A3/A4 Light & medium intermittent duty: For maintenance shops, spare parts warehouses, low daily operation frequency. Model: LD, LX, LB.
● A5 Medium heavy frequent production duty: Daily continuous loading, regular near-full load, most popular for export. HD European standard A5 (FEM 2M).
● A6 Heavy multi-shift duty: Multi-shift continuous heavy load, high impact. Only LDY metallurgical type is applicable; single girder are not recommended above A6.
Step 3: Confirm Working Environment Special Requirements
● Ordinary normal environment (no hazard, normal temperature): Choose standard LD single girder crane, economical and widely used.
● Low ceiling, limited vertical space: Select HD European Low Headroom type, compact trolley reduces headroom occupation and maximizes effective lifting height.
● Flammable & explosive gas/solvent workshop (paint, chemical, pharmaceutical, oil depot): Choose LB explosion-proof single girder, Ex d II BT4 / CT4 optional for Zone 1 & Zone 2.
● High temperature hot casting, molten metal workshop: LDY heat insulation metallurgical single girder with high-temperature resistant hoist.
● Bulk granular cargo (coal, sand, grain, mineral slag): LDZ grab bucket single girder with electric grab for automatic bulk grabbing.
● Light steel plant, narrow workshop without side runway beams: LX underslung suspension crane, suspended under roof I-beam, no supporting girders required.
Step 4: Select Hoist Configuration
● CD single speed wire rope hoist: Low cost, simple structure, for general non-precise lifting.
● MD dual speed wire rope hoist: Fast speed for efficiency, slow speed for accurate positioning, mold & assembly workshops preferred.
● Integrated VFD European hoist (HD exclusive): Stepless speed regulation, low noise, small vibration, high positioning accuracy, export high-end configuration.
Step 5: Auxiliary Function Optional Selection
● Control mode: pendant push button /wireless remote control /cabin control.
● Safety devices: overload limiter, upper & lower limits, anti-collision buffer, emergency stop.
● Driving type: fixed speed /variable frequency drive (smooth start & stop, reducing impact to workpiece).
Step 6: Verify Plant Civil Structure Condition
● Overhead runway beam bearing capacity: Calculate total crane dead weight + max load, confirm beam load limit provided by construction factory.
● LX suspension special check: Roof I-beam bearing capacity must meet suspension wheel pressure.
● Space clearance: Confirm side distance between crane and wall, avoid collision during travelling.
Step 7: Budget & After-Sales Service Comparison
● Limited budget, general light workshop: LD standard model with CD hoist.
● Export project, high precision, long service life demand: HD European low headroom crane.
● Long-term heavy-duty production line: increase safety margin, upgrade A5 duty class + VFD drive.
● Manufacturer qualifications to confirm: ISO, CE, explosion-proof certificate, after-sales installation & maintenance support.
