Some of electric parts for Tower Crane:
1. Electric motor: Tower cranes use electric motors to power the lifting and rotation mechanisms. These motors convert electrical energy into mechanical energy to move the crane's various components.

The prosperity index was jointly compiled by the China Economics Research Center of the Economic Times and the China National Economic Monitoring Center of the National Bureau of Statistics. The index report stated that the early warning index for the equipment manufacturing industry in the first quarter was 113.3 points, an increase of 20 points over the previous quarter. The green light zone continues to run upwards.
Pan Jiancheng, deputy director of China's economic monitoring center, believes that the rising prosperity index of the equipment manufacturing industry and the warning index indicate that the industry's economic conditions continue to improve.
According to analysis, the boom in the equipment manufacturing industry in the first quarter was mainly attributable to the recovery of the domestic demand market, the continued rapid growth of corporate sales and the moderate recovery of prices, the continuous and rapid growth of corporate profits and taxes, and the apparent increase in employment demand.
The index report analyzes that there are many favorable conditions for the current development of the equipment manufacturing industry, but because the development of the equipment manufacturing industry has a high degree of policy dependence, attention should be paid to the fact that there are still large uncertainties in the recovery of external demand. At present, it is not favorable for the withdrawal of relevant policies. opportunity. We should further strengthen the implementation of the “Restructuring and Revitalization Plan for the Equipment Manufacturing Industry†and adopt more active policy measures to encourage and guide private capital investment.
2. Control system: Tower cranes require a sophisticated control system to manage the movement and operation of the crane. This includes controls for lifting, lowering, slewing, and trolleying.
3. Limit switches: Limit switches are used to set the maximum and minimum positions of the crane's various components. They help ensure safe and accurate operation by preventing the crane from exceeding its designated limits.
4. Power cables: Tower cranes require heavy-duty power cables to transmit electricity from the power source to the crane's electrical components. These cables need to be durable and capable of handling high voltage and current.
5. Circuit breakers: Circuit breakers are essential safety devices that protect the crane's electrical system from overloads and short circuits. They automatically interrupt the electrical current flow when a fault is detected, preventing damage to the crane and reducing the risk of electrical fires.
6. Transformers: Transformers are used to step up or step down the voltage of the electrical supply to match the requirements of the tower crane. They ensure that the crane receives the correct voltage for optimal performance and safety.
7. Sensors: Tower cranes often incorporate various sensors to monitor and control different aspects of their operation. These sensors can include load sensors, wind sensors, angle sensors, and anti-collision sensors. They provide crucial data to the control system, helping to ensure safe and efficient crane operation.
8. Emergency stop switches: Tower cranes are equipped with emergency stop switches that can quickly shut down the crane in case of an emergency or safety hazard. These switches are strategically located and easily accessible to crane operators.
China's equipment manufacturing industry continued to rise
A few days ago, the "Report on the Equipment Manufacturing Industry Climate Index for the First Quarter of 2010" released by the China Economics and Economy Center of the National Bureau of Statistics showed that the equipment manufacturing industry's climate index was 99.4 points in the first quarter of 2010, and the economic standard was 100 points, up from the previous quarter. The 0.7 point has been rising for the third consecutive quarter, basically returning to the initial level of the rapid growth cycle from 2003 to 2008, that is, the level of the first half of 2003.
