Selection Of Gantry Cranes
- Apr 09, 2018 -

Selection of gantry cranes

(1) Selection of single main beam and double girder gantry cranes

Under normal circumstances, the lifting capacity is less than 50t and the span is within 35m. There is no special requirement for use, and a single girder type should be used. If it is required that the width of the door legs is large, the working speed is high, or heavy items or long and large pieces are often hoisted, double-girder gantry cranes should be selected.

(2) Span and Cantilever Length

The span of a gantry crane is an important factor affecting the quality of the crane itself. In the selection, the span should be minimized on the premise of satisfying the conditions of equipment use and meeting the span series standards.

(3) Principle of determination of wheelbase

(a) It can meet the stability requirements of the gantry in the direction of the crane track;

(b) The size of the cargo must be able to pass through the leg flat steel frame smoothly;

(c) Pay attention to make the distance between track B and span S in a certain proportion, generally take the track distance B = (1/4 - 1/6)S.
