In India, multiple tower cranes are now working within one building or one construction site. Collision between the tower cranes, nearby structures, trees or other towers often happen, which in turn damage the crane/other structures, resulting in heavy losses, sometime stalling the project and even fatal accidents.
After a year-long market study, it has been seen that most of the tower cranes do not have anti-collision systems. Even the Safe Load Indicator (SLI) is not installed. Some tower cranes have safe load indicators but are unable to link with the anti-collision systems. Multiple monitor/displays in operator’s cabin also confuse the operator and lead to accidents. Frequent power failure at construction sites adds problems like improper shut down, data corruption, non-detection of radio signals, restart etc.
After studying all these problems, Everest Engineering, has developed an anti-collision system with built-in SLI and wind velocity control that gives tremendous safety for any make/model tower cranes. 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. A 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. 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.
This system is developed with a microprocessor, with battery backup so any power failure at site does not affect the functioning. The communications are made through radio controls with non-licensed frequencies specified by Ministry of Communication, Govt. of India. L & T, JMC, Simplex, Billimoria, BG Shirke etc are our major customers since the last 4-5 years. We also conduct onsite training as part of our warranty policy.
