HST7528 16t Tower Crane of Top Kit Tower Crane
Hst7528 16t Tower Crane of Top Kit Tower Crane

Flat top tower cranes
Flat top tower cranes don't have the "tops" of conventional cranes; 
they can be used in conjunction with other tower cranes at sites where space is confined or near the airports.
A working crane is a profitable crane, and Flat top tower cranes are built to work.
They're well suited for heavy lifting and placement duties on the most challenging jobsites. And they can also help you save time on other jobsite duties by easily moving materials from one area to another.
From the efficient setup that gets you working quickly to the variety of jobsite duties it can handle, you'll get great value from your Flat top tower crane every day.
The HST series includes crane models from 50 to 720 mt.
1. Quality manufacturing designed for reliable performance hour after hour
2. Easy maintenance access and built-in safety features to keep downtime to a minimum
3. Ergonomic cabs provide the comfort required for long hours on the job

1.4  working mechanisms 
    Working mechanism include: lifting mechanism, slewing mechanism, trolley traveling mechanism and climbing mechanism.
1.  lifting mechanism
Lifting mechanism use AC asynchronous motor to control speed, it consist of variable frequency motor, plum coupling, reducer, drum shaft assembly, brake ,rack, etc.. Through frequency converter changing input power`s frequency to change lifting speed; when mains frequency is equal to or less than rated frequency, the lifting mechanism can lift rated load; when mains frequency is greater than rated frequency, with the rising of speed, the weight that lifting mechanism can load will decline. Lifting mechanism is always in braking position when it doesn't work. There a height limiter in the other side of dram shaft, the height sensor of safety monitoring system is connected with height limiter.
