Flat-top Tower Crane PT7040-16

Features of flat top tower cranes
For even higher performance and greater operational options:
with its modular jib and without tie bars, the topless crane saves time and money.
The advantages of a modular jib without tie-bars:
Lower overall height(mutiple crane sites)
Easy jib erection and dismantling
Jib configuration can be easily modified as the works proceed,
can be erected and or dismantled “ in the air”, section by section
