Disadvantages for using a luffing jib tower crane / But there are some disadvantages of the ‘luffers’ when you compare them to other types of tower crane
1> The price of the luffing jib tower crane is much higher than a regular tower crane. The tower frames of a ‘luffer’ are stronger, and the luffing mechanisms are much bigger than the hoist system of a tower crane. Of course the technology applied to move the jib, counterweights, etc is the highest.
2> The cost of assembling and dissassembling are much higher too. Most of the structures are heavier, and it takes longer to erect a luffing jib tower crane. Once again, to erect a luffer is more difficult due to the technology applied, etc.
3> The jib of a ‘luffer’ acts as wall to the wind, and the ‘moment’ is much bigger. So the restrictions of the tower are higher.
4> Due to the luffers don´t have trolley motor (the movemnet is made by the total jib), the working process are slower than in other type of tower crane.
