The advantages of the crane:
1. The section of the jib is much larger than the standard topkit tower crane, hence the jib is more studier.
2. When there is need to place many cranes in one area, with over lapping jib, height of the 2ND crane required will only be 1-2Mtrs higher than the first crane. In normal cranes, this height needs to be minimum 9Mtrs.
3. Since the size of the jib cross section is large, it is more convenient to do the maintenance of the Trolley Motor/Trolleying system.
4. Topless cranes are easy to assemble and dismantle as there is no Tie Rod system and time required is less.
5. No possibilities of accidents due to loosening of Tie Rod pin/lock pins.
