Product Description
QTZ50 Tower crane composes metal structure, mechanism deriving, hydraulic lifting, power control and safeguard. The detailed information as follows:
The foundation frame is fixed on the special concrete foundation. The upper part of the frame connects with the tower mast, and the upper part of the crane mast connects with the lower supporting board which connects the lifting jacket. The other end of the lower supporting board fixed to the slewing bearing's outer circle.

The rotary parts which fixed to the inner part of slewing bearing including the upper rotary platform, tower cap, balance arm, jib boom, range changing cart and the hook, counterweight, hoisting mechanism as well as slewing mechanism and the driver's cab. All the parts can make a 540° Rotary around the crane.
The jib boom connects the tower cap by two draw bar while its root part connects the upper rotary platform by bolts.

Hoisting mechanism is at the middle rear end of the balance arm. The right of the slewing platform is the slewing mechanism and the left part is driver's cab. Both the range changing cart and the hook are on the root part of the jib boom, guiding by the derricking speed mechanism, shifts on the jib boom.
The height of the crane includes the height of foundation and standard section.
