Tower crane electrical parts work together to control the various movements of the crane, including hoisting, slewing, and luffing. Here's a simplified overview of how they function:

l Power Supply: The crane's electrical system is powered by a reliable power source, typically provided by the construction site.

l Control Panel: The operator uses the control panel to input commands, such as hoisting a load or rotating the jib.  

l Control System: The control system processes the operator's commands and generates electrical signals.

l Motors: The electrical signals are transmitted to the motors, which convert electrical energy into mechanical energy to drive the crane's movements.

l Sensors and Limit Switches: Sensors monitor the crane's position, load weight, and other critical parameters. Limit switches prevent the crane from exceeding its safe operating limits.  

l Frequency Inverters: Frequency inverters adjust the frequency and voltage of the power supply to the motors, allowing for precise control of speed and torque.  

l Wiring and Cabling: The wiring and cabling system transmits power and control signals between the various components of the crane.
