The TAC-3000 Anti-Collision feature detects and anticipates the risk of hook block, jib, or counter jib collision when multiple cranes of different or same height are in use. The TAC-3000 allows the operation to remain in the control of the operator until safe parameters are breached. In the event of a collision risk, the TAC-3000 utilizes stages of protection including audible warnings, slowing of the jib, hook block, or counter jib, and the eventual stopping of movement to prevent collision. Parameters set for these features are flexible to control load swing and customizable to each site.
The TAC-3000 Boundary Protection feature can be preset with a 25-point boundary protection area in which the hook block cannot operate or over-fly. The boundary protection feature is especially important when tower cranes are being used in congested areas common in cities and rehabilitation areas and when operating near power lines.
The TAC-3000 Zone Protection feature can determine up to six prohibited zones (eight points each) in which the hook block or jib are not allowed to operate. It prevents the hook block from over-flying restricted zones like buildings, highways and other public areas.
Developed by E-Build Innovations, the TAC-3000 has been in use in Singapore and Korea for two years and is being introduced to the North and South American markets by Persha International, Inc., a United States company that also conducts heavy equipment safety training and NCCCO Certification.
The TAC-3000 has been installed and is successfully running on four tower cranes at the McCarthy/Pinnacle Casino Project in St. Louis, Missouri where the anti-collision, boundary, and zone protection features are all being utilized. Successful installs at the University of Berkeley have also been completed, where zone protection within the busy campus is critical.
