Tower crane frequency conversion system scheme

HMI+IPLC intelligent control, device operation information at a glance.Tower crane lifting is controlled by HD50-L3 closed-loop, swing is controlled by HD30-HZ open-loop and amplitude is controlled by HD30-TC open-loop, which ensures the safety, efficiency and stability of the whole process.

Scheme Advantages

·Zero-frequency braking, zero-speed suspension

·Protection function of anti-scour top

·Automatic detection of light load, high speed, constant power and speed limitation

·Swirl-free rotation

·Inch function

·Anti-hooking

Tower crane integrated system scheme

The common bus scheme can reduce electric energy loss even more.Built-in Internet of Things module can realize remote monitoring and remote fault diagnosis.Operators can monitor the operation of each tower via mobile phone APP, host computer and remote platform.

Scheme Advantages

While retaining the functions of the original scheme, the following new designs have been added:

·Integrated design of lifting, swing and amplitude variation

·Black box design

·Innovative heat dissipation design, mute design

·Can be installed directly in the driver's cab for easy turnaround
