Safety Distance for Operation of General Gantry Cranes
Time:2017.12.26 Click:1766

General gantry cranes are mainly divided into single-girder and double-girder types. In practical application, the appropriate type shall be selected according to actual working conditions to meet lifting operation requirements, and the safety distance shall be set accordingly to ensure the safety and stability of operation. What principles should be followed when setting the safe operating distance for gantry cranes?

To meet the stability requirements of the gantry along the crane track direction, the crane wheel spacing shall be determined first. The basic principle is to ensure that the outer dimension of goods can smoothly pass through the planar steel frame of the outriggers. Meanwhile, a certain clearance shall be reserved between the external dimensions of the gantry crane and the goods and vehicle passages in the yard to facilitate loading and unloading operations.

When vehicles carry out loading and unloading within the crane span, a distance of no less than 0.7 meters shall be maintained from the crane gantry legs. When the lifting gear is not in operation, it shall keep a clearance of more than 0.5 meters from vehicles. A spacing of over 0.5 meters shall be ensured when goods pass through the gantry legs. The above three sets of safety data must be strictly observed.
