Feature | HD
(European type single girder overhead crane) | LD
(Traditional type single girder overhead crane) | Design | Modular design originated from Europe
(motor, reducer, electrics separated, easy to maintain) | Integrated design
(Hard to maintain) | Appearance | 
| 
| Working class | M5 | M3 | Lifting height | 4.15m
(Low headroom is a basic feature of European type hoist.) | 4.05m
(We use low headroom type hoist to enable maximum lifting height in LD model.) | Lifting mechanism | 
Motor, reducer and brake 3-in-one, soft start for smooth running, long life design, maintenance free
Wire rope breaking force: 2160N/ mm2
Rope diameter: 9mm
Wire rope does not need oil.
Rope guide: industrial plastic (small friction with wire rope)
| 
Wire rope breaking force: 1670N/ mm2
Rope diameter: 15mm
Wire rope needs oil.
Rope guide: Iron (big friction with wire rope) | Lifting speed | 0.5~5m/min (inverter control) | 4m/min (single speed) | Trolley travelling speed | 2~20m/min (inverter control) | 20 (single speed) | Crane travelling speed | 2~20m/min (inverter control) | 20 (single speed) | Electrics | Schneider | CHNT （origin from China） | Maintenance | Maintenance free, no need to add oil 3~5 years | Gear box, wire rope needs to add oil every year. Will need to stop production for maintenance. | Noise | Little noise, environmental-friendly at work | Big noise in warehouse | Total weight | 6.5t | 7.14t |
