How to ensure the safety of crane selection methods:

Today, following the editor from Shandong Longmen Crane Manufacturer, let's learn about the selection method of cranes and how to ensure safety. Interested friends, let's learn together:

1. Selection of single beam crane and double beam gantry crane.

In general, when the lifting capacity is below 50t, the span is within 35m, and there are no special usage requirements, a single main beam type should be selected. If a large door leg width, high working speed, or frequent lifting of heavy and long items are required, a double beam gantry crane should be selected.

2. Span and cantilever length.

The span of a gantry crane is an important factor affecting its own quality. In the selection process, the span should be minimized as much as possible while meeting the equipment usage conditions and complying with the span series standards.

3. The principle of determining the wheelbase.

(1) Can meet the stability requirements of the gantry along the direction of the crane track.

(2) The external dimensions of the goods should be able to smoothly pass through the leg flat steel frame.

(3) Pay attention to making the wheelbase B proportional to the span S. Single beam cranes generally take the wheelbase B=(1/4-1/6) S.

(4) Determination of spacing dimensions for gantry cranes.
