Single Girder Or Beam Pendant Line Control Truss Type Electric Hoist Traveling Gantry Crane

Description:

The gantry crane is a bridge-type crane in which the bridge is supported on the ground track through the outriggers on both sides. In structure, it consists of gantry, cart running mechanism, lifting trolley and electrical parts. Some gantry cranes only have outriggers on one side, and the other side is supported on the factory building or trestle, which is called a semi-gantry crane. The upper bridge frame of the gantry crane (including the main beam and end beam), outriggers, lower beams and other parts. In order to expand the working range of the crane, the main girder can extend beyond the outriggers to one or both sides to form a cantilever. A hoisting trolley with a jib can also be used to expand the crane's operating range through the pitch and rotation of the jib.

How to choose:

1. Selection of gantry crane
Comply with the relevant regulations of GB/T14406-1993 and GB5905-86 for general gantry cranes.
Under normal circumstances, the lifting capacity is less than 50t, the span is less than 35m, and there are no special requirements for use, the single main beam type should be selected. If the width of the gantry leg is required to be large, the working speed is high, or the heavy and long pieces are often lifted, the double-girder gantry crane should be selected.

2. Span and cantilever length
The span of the gantry crane is an important factor affecting the quality of the crane itself. In the selection, the span should be minimized under the premise of meeting the equipment use conditions and meeting the span series standards.

3. The principle of determining the wheelbase
(a) It can meet the stability requirements of the gantry along the direction of the crane track;
(b) The overall dimensions of the goods should be able to smoothly pass through the flat steel frame of the outriggers;
(c) Note that the wheelbase B is proportional to the span S. Generally, the wheelbase B=(1/4-1/6)S.

4. the gantry crane spacing size is determined
During work, there should be a certain amount of space between the external dimensions of the gantry crane and the passage of goods and transport vehicles in the yard to facilitate loading and unloading operations. When loading and unloading within the span, the general transport vehicle should keep a distance of more than 0.7m from the door leg. When the spreader is not working, there should be a distance of more than 0.5m from the transport vehicle, and when the goods pass through the door legs, there should be a distance of more than 0.5m.
