Gantry crane selection design manufacturer requirement

Oct 08, 2016
Gantry crane can be divided into single girder gantry crane and double girder gantry crane, when select and design a gantry crane, it should not only  pay attention to customers requirement, but also should notice the requirement about the gantry crane manufacture standard, it is very important to gantry crane manufacturer.

(1) Single & Double girder selection requirement
Under normal circumstances, it should use a singlr girder gantry crane when lifting capacity is below 50 ton,  span is less than 35m,  without other special requirements. If the large span. high working speed, or often lifting heavy and long pieces, it is appropriate to choose double beam gantry crane.
 
(2) Span length requirement
Gantry crane span is an important factor affecting the crane quality. During selection, on condition that satisfy the equipment and meets the span standard, should reduce the span as far as possible 
 
(3) Track distance selection principle
(A) Must can meet the gantry traveling stability requiement 
(B) The cargo can pass the steel frame smoothly
(C) Notice the the wheelbase "B" and the span "S" should be into a certain proportional relationship, the general take: B = (1 / 4-1 / 6) S.
 
(4) Determine gantry crane spacing size
During working, there should be some space betwwen gantry crane and yard goods or transport vehicles, for smooth loading and unloading operations. In general, when the transport vehicles working betwwen two suppot legs, should keep distance more than 700mm with support legs. Spreader should keep distance more than 500mm with transport vehicles.
 
(5) Gantry crane electrical equipment selection requirement
The electrical equipment should meet the relevant provisions about general gantry crane GB / T14406-1993.
