How to ensure safety when two or more cranes working at site

When two or more Tower Cranes are working at close range in the same building yard can interfere each other. The following precautions must be taken:

1) Jibs must be offset to avoid collision of any structural parts considering the maximum oscillation amplitude and a reasonable safety distance.

2) The minimum distance between the two cranes must anyhow be great enough to prevent the cables and loads of the higher crane from interfering with the lower crane.

3) In case of interfering cranes electrical or radar anti-collision devices can be installed to limit the crane working range. Always consult the manufacturer for the installation of this Safety Device, once ascertained it really serves the purpose.

Remember that cranes must be always staggered in height to avoid any interference when under no-working conditions.

An Anti-Collision System for a Tower Crane is designed to prevent collisions between multiple tower cranes operating on the same construction site. It uses various sensors and technologies to detect the presence of other cranes and obstacles in the crane's path, and then automatically adjusts the crane's movements to avoid collisions.
