(1) The power supply of the bridge crane is three-phase AC (three-phase four-wire system), the frequency is 50Hz / 60Hz, and the voltage is ≤1000V (can also be 3kV, 6kV or 10kV according to needs). The voltage fluctuation of the power supply system at the access point of the crane feeder should not exceed ± 10% of the rated voltage.
起重机运行的轨道安装应符合GB/T级公差要求。 (2) The track installation of the bridge crane shall comply with GB / T tolerance requirements.
The grounding resistance of the crane running track should not be greater than 4Ω.
The altitude of the place where the crane is installed and used does not exceed 1000m (if it exceeds 1000m, the capacity of the motor should be checked according to the provisions of GB 755, and when it exceeds 2000m, the capacity of the electrical components should be checked.)
(3) The radiant heat temperature of the lifting articles to the hook part of the crane should not exceed 300 ° C.
起重机在室内工作时的气候条件: (4) Climatic conditions when the bridge crane is working indoors:
The ambient temperature does not exceed + 40 ° C, and the average temperature within 24h does not exceed + 35 ° C;
Ambient temperature is not lower than -5 ° C; relative humidity does not exceed 50% at + 40 ° C.
重机在室外工作时的气候条件: (5) Climatic conditions when the bridge crane works outdoors:
The ambient temperature does not exceed + 40 ° C, the average temperature within 24h does not exceed + 35 ° C, and the ambient temperature is not less than -20 ° C. Relative humidity when the ambient temperature does not exceed + 25 ° C is allowed to temporarily reach 100%.
(6) The working wind pressure should not be greater than: 150Pa inland (equivalent to class 5 wind) and 250Pa in coastal area (equivalent to class 6 wind); maximum wind pressure in non-working state: generally 800Pa (equivalent to class 10 wind) It can also be agreed separately.
