Beijing began to implement the lead-free process of gasoline. The fourth item of fuel consumption and emissions involved in the old standards prohibits the use of leaded gasoline in automobiles. The gas stations are the same outside, and the new standard adds a clause that the repairs and adjustments are still up to date. If it does not meet the requirements of the State for the technical safety conditions of motor vehicles, it shall be scrapped. In addition, starting from China’s national conditions, the new standard also provides that certain vehicles with good technical conditions can reach a certain amount of maneuvering space to achieve the end-of-life mileage and useful life, so that the retirement can be postponed, but it must not exceed half of the prescribed retirement period (4 to 5 years). . The Ministry of Construction and the Ministry of Public Security jointly promulgated the "Measures for the Administration of Urban Taxi" and began implementation. The "Measures" set out in detail the taxi business management qualification management, passenger service management and inspection, and complaint punishment. 3. The representative of the First Session of the Ninth National People's Congress proposed that the provisions of the Air Pollution Prevention and Control Law promulgated in 1987 on the prevention and control of automobile exhaust pollution cannot meet the changes in recent years in large and medium-sized cities. Immediately after the relevant departments introduced (i Gas Vehicles, Motorcycles and Vehicle Engine Products Pollutant Discharge Monitoring and Management Measures), there are laws and regulations for the prevention of exhaust gas pollution.
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.

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.
