>>>Main Parts for Tower Crane:
Qtz125 (6015) 8ton Electric Building Construction Top Kit Tower Crane

>>>Feature of QTZ125(6015) 8ton Tower Crane: 
1. Hoisting Mechanism
The tower crane uses a large-size winding drum and the motor with three kinds of speed or with
variable frequency system.

2. Slewing Mechanism
The continuously variable frequency speed regulation helps the balance crane to work with stable
starting and braking as well as fast and accurate positioning. Therefore, our tower crane becomes
the leading one in terms of performance and operability at home and abroad.

3. Luffing Mechanism
Adopting variable frequency speed regulation, the luffing mechanism works stably with little impact.
4. Control System
The PLC allows for automatic detection of electrical fault and issues corresponding sound and light
alarm. Critical components are all procured from international famous enterprises.

5. Safety Protection Device
Our tower crane is equipped with many advanced or ingenious components apart from regular
safety devices used in ordinary cranes for the purpose of enhancing its security and operating

6. Structure
Tanks to the advanced design tools, such as electro-mechanical design, CAD design, optimization
design, and modular design, the tower crane proves to be a kind of optimum construction
equipment that shows not only superb strength, stiffness and fatigue resistance but also
outstanding comprehensive performance and reliability.

>>>Safety Features of the Tower Crane: 
1 Torque limiter it will warns when lifting weights reach to 90% of rated lifting torque. When reach to 110% of the rated lifting torque, it will limit rising upwards and trolley.
2 Weight limiter Control the maximum lifting capacity, lifting weight reach to 40% of the rated capacity, limit high-speed lifting; lifting weight reach to 110% of the rated capacity, limit  the lifting up
3 Height limiter Control the lowest and highest extreme position of lifting hook
4 Slewing limiter Control the extreme turns number of turn left and right
5 Amplitude limiter Control trolley limit position of inward and outward 
6 Overload protection If the material is over the capacity, the crane will give a sharp warning for protection itself
7 Emergency brake If the operation staff  encounter some emergency situation, we could start the emergency brake system to protection the related treasure
8 Control Method Room control or remote control to avoid any injury to the operation staff

A luffing tower crane is a good choice for work sites where two or more cranes are working at the same time. This is because the slewing radius of a luffing crane is highly reduced in comparison to standard tower crane types. The luffing jib tower crane also has a higher lifting capacity because the weight is transferred from the crane`s jib much more effectively.
