The effects of wind pressure and braking force on gantry cranes
When a fully loaded sports car is in its usual position at both ends, the struts are subject to huge vertical stresses. For a gantry crane with an outstretched arm, when the sports car is at the end point of the outstretched arm, the pillars are subject to huge vertical stress.
Gantry cranes with outstretched arms must enable sports cars and transported goods to pass freely through the pillars.
A gantry crane with one or two outstretched arms has a bending moment diagram and a scissor diagram due to its own weight and dynamic load. The braking force of a sports car can be calculated. The coefficient of friction between the wheels and the track is 0.15.
Longitudinal wind pressure of the bridge (when fully loaded): take 20-25 kg/square meter. Horizontal forces (in the direction of the sports car track) due to wind pressure and braking forces.
To determine the stress on the angle iron on the main beam, you can refer to what we said before in detail. If we install the sports car track on the lower edge of the longitudinal beam and place it on an appropriate suspension mechanism, the structure of the pillar and its connection with the main beam will The connection of beams is the simplest. This suspension mechanism also serves as a connection to the reinforcement frame, transmitting all horizontal forces (mass force and wind force) to the horizontal coupling frame on the plane of the longitudinal beam.
