Electric single girder suspension crane span 9 meters 500 kg bridge crane
1. Column-free design
The main beam is directly suspended on the steel structure of the workshop roof or the lower flange of the special I-beam track, which does not occupy the ground space and is suitable for places with narrow passages (such as assembly lines and warehouse mezzanines).
2. Minimalist main beam structure
Cold-rolled I-beams or box beams (section height is usually ≤300mm) are used, with a deadweight of only 300~500kg and low requirements for roof load (generally ≤1.5 tons/point).
3. Modular components
Standard segment main beams (3~9m/segment) can be quickly spliced to adapt to different spans (usually ≤16m).
4. Low investment cost
The price of the whole machine is about 30,000~80,000 yuan (only 1%~3% of double-beam bridge cranes), and the installation fee is less than 10,000 yuan.
5. Fast deployment
It only takes 2~3 weeks from ordering to production (heavy-duty bridge cranes take 3~6 months).
6. Extreme optimization of energy consumption
Power consumption of 500kg running for 1 hour is ≤0.5kWh (equivalent to 1/3 of the power consumption of household air conditioners).
7. Key points of safety design
Load protection: electronic overload limiter (error ±5%), automatic power cut-off at 110% rated load
Stroke protection: spring buffer (collision force ≤5kN) + mechanical block
Emergency brake: automatic brake when the motor loses power (braking distance <50mm)
Electrical safety: ground fault protection + control circuit safety voltage
