The use of single girder and double girder gantry cranes:

1. In general, the hoisting weight is less than 50t, the span is within 35m, and there is no special application regulations, so the single main beam type should be adopted. If it is specified that the gate legs are generally wide, the working speed is high, or heavy and large objects are often hoisted, double beam gantry cranes should be selected. Crane air conditioning.

2. Span and suspended wall length

The span of a gantry crane is a key factor that endangers the quality of the crane itself. In the selection, the span shall be avoided as far as possible under the premise of considering the application standards of machinery and equipment and conforming to the span series product specifications. Crane air conditioning.

3. Clear standard of track width

(1) The reliability provisions of gantry along crane rail can be considered.

(2) The size of the goods shall be in accordance with the steel frame structure of the support plan.

(3) Note that the track width B is related to the span S in a certain proportion. Generally, the track width B=(1/4-1/6) S.

Before the crane air conditioner works, it is necessary to investigate and study the natural environment of the site, and also to carry out the layout and improvement of the site foundation, so as to ensure the smooth development of electric work. Crane is a mechanical equipment composed of cables, iron chains, movable pulleys and other parts. The crane must use the lifting chain in its work, which is a key part of the crane. Naturally, the crane has high requirements on the characteristics of gear oil, and the crane air conditioner.
