This system, when installed on the two adjacent cranes, will avoid the collision of two cranes. The Anti Crane Collision Switch is designed to avoid the collision of two adjacent cranes in the same bay running on the same rails. Tower Crane anti collision System Working principle of anti-collision device The communications are made through radio controls with non-licensed frequencies. This system is developed with a microprocessor, with battery backup so any power failure at the site does not affect the functioning. This system integrates with the tower crane panels and will take care of the cut-off, alarm and display automatically without changing any OEM set-up. These anti-collision devices (ACD) come with a ground monitoring system through which one can monitor the functions of all tower cranes as well as upload data changes (like height increasing, protect some zones, etc) without stopping the cranes.Ī single display shows the anti-collision functions, as well as the SLI, functions like load, radius, hook height, slewing angle and wind velocity to the operator without any confusion.
Tower Crane anti collision System Anti collision device for cranesĪfter studying all these problems, an anti-collision system has been developed with built-in SLI and wind velocity control that gives tremendous safety for any make/model tower cranes.
Frequent power failure at construction sites adds problems like improper shutdown, data corruption, non-detection of radio signals, restart, etc. Multiple monitors/displays in the operator’s cabin also confuse the operator and lead to accidents. Some tower cranes have safe load indicators but are unable to link with the anti-collision systems. Even the Safe Load Indicator (SLI) is not installed. 3 Working principle of anti-collision deviceĪfter a year-long market study, it has been seen that most of the tower cranes do not have anti-collision systems.
