Tower crane components:

General speaking, according to the different functions, the tower crane can be divided to ground foundation, tower body, climbing, slewing, hoisting, lifting boom, counter jib, trolleying dolly, tower head, operation room, trolleyinging parts,

There is the concrete ground foundation which the tower crane stands on.

The tower head is made up of the mast sections, which can be rising up by the hydraulic climbing part.

Slewing system can assure the parts above the slewing rotate left and right.

Hoisting system can assure lift up and down.

Counter jib can assure the moment balance.

Lifting boom bears the force of the lifting. And it is the range changing dolly runway.

The dolly is used for fixing the pulley block, wire steel rope and hook.

Tower head keeps balance for boom bearing force.

The operation room is where the worker operating the tower crane.

Trolleying system runs forward and backward on the horizontal direction.

The Features of QTZ125 (6015)

1): The main stressed steel parts of QTZ125 tower crane use Q345B steel, the tower body mast section 1.835m*1.835m*2.5m, using on-chip-type or standard mast section of two forms of production

2): Light weight, air resistance is small, convenient transportation. Rotation adopts double rotary organization. Lifting mechanism is driven by frequency converted motor, running steady

3): It adopts standard section hydraulic lifting and connecting, and can decide the crane height according to the actual height of the building

4): High-quality surface coating that can meet different requirements of transporting and using. It is durable under environments of low, high, wet as well as oceanic environment

5): The crane has full set of safety devices, which ensure the safe and high efficiency. It has lifting height limiter, dolly range-change limiter, moment limiter, weight limiter, slewing limiter, etc

6): The coiling frequency motor and mono-speed ratio decelerator is applied in the lifting mechanism, which enables heavy load low speed and light load high speed

7): The range-change structure drives the dolly to change range on the horizontal arm, with good positioning performance

8): Planet gear decelerator is used in the slewing structure, together with moment-limiting hydraulic coupler, which ensure high load capacity, steady starting and reliable operation

Application field: Building height up to 60 floors (180m),loading capacity up to10t, jib length is60m or little more.
