Gantry cranes supplied by crane manufacturers are widely used in shipbuilding, road repair, bridge erection, outdoor freight yard, bulk cargo yard, bulk cargo handling and other scenarios. Portal crane is also called gantry crane or gantry crane in many places. It has high utilization rate, wide working range, wide adaptability and strong practicability, but improper selection during procurement will affect the project production progress. Therefore, the user should follow the corresponding principles when selecting the gantry crane. The following is your analysis:
1. Under normal conditions, the lifting capacity is less than 50t and the span is within 35m. If there is no special use requirement, the single main beam type shall be selected. If the gate legs are required to be wide and the working speed is high, the double beam gantry crane shall be selected.
2. The span, cantilever length and the span of the gantry crane are the key factors to determine the quality of the crane.
3. The principle for determining the track width shall meet the stability requirements of the gantry along the crane track; The size of goods shall be able to successfully complete the plane steel frame of support feet; Take care to make the wheelbase proportional to the span.
4. Spacing dimension of gantry crane. During operation, certain space dimension shall be reserved between the external dimension of gantry crane and the cargo and transport vehicle passageway in the storage yard to facilitate loading and unloading.
