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
Never before has there been a crane that is so easy and quick to erect in total safety
Hoisting and trolley ropes installed on the ground, plug-in connections for electrical equipment and safety devices, time-saving factory assembly of cab
Variable frequency slewing, continuously variable speed control by means of a stepless controller, that also adapts to the crane operator's drving style.
Variable frequency hoisting, speed continuously adjusted and optimised according to the load being handled, very slow speeds, smooth speed changes, high productivity.
The masts adopt the standard bases, allowing it to be adjusted to the desired height
The adjustable bases provide a choice of method of installation
-on fixing angles
-on cross-shaped base
-on travelling gear
Or as a climbing crane
