How to choose electric gantry cranes reasonably

Dec 21, 2017
Electric gantry crane is a large duty material handling crane, the price is relatively high, but also has relatively high requirement to the factory site, facilities, so when choosing gantry cranes, must be cautious. Reasonably choose the electric gantry crane can be considered from the following points:
 
1. Choose single girder gantry crane or double girder gantry crane
Under normal circumstances, the lifting capacity is not more than 30 ton, span is less than 35m, and no other special requirements, should choose single girder gantry cranes, it is enough for working and the price is relatively affordable. If the lifting capacity is more than 50 ton, span is greater than 35m, or higher work intensity, more requirement on stability and safety, should choose double girder gantry crane.
 
2. How to determine the track span
During determining the track, in accordance with the following principles for analysis:
(1) To ensure the electric gantry crane run stably along track direction.
(2) The track span is generally (1 / 4-1 / 6) S, S is the electric gantry crane span size.
 
3. How to determine the spacing
Electric gantry crane should keep a distance of more than 0.5m between crane support legs and transport vehicles when non-working.
 
4. How to determine the span, cantilever length
Should use the min span and cantilever length based on meet the use conditions and be in line with the use standards.
 
5. The requirements of electrical equipment
The selection of electrical equipment should be comply with GB / T14406-1993 standards.
