1. Telescopic boom section: This is the retractable part of the main boom that allows the crane to reach different heights. It can be adjusted in length to meet different lifting requirements.

2. Boom head: This component is located at the top of the main boom and serves as the connection point for rigging and lifting equipment.

3. Main load line: This is the main cable or rope used to lift the load. It runs from the winch through the boom and through the pulleys at the boom head.

4. Anti-double block limit switch: A safety device that prevents the hook from colliding with the top of the boom. It prevents the main load line from retracting too far

5. Main hook pulley block: This is the large, usually multi-pulley component located at the end of the load line. It allows multiple line configurations to increase lifting capacity.

6. Hook latch: A safety latch that prevents the load from accidentally sliding off the hook.

7. Access ladder: Provides safe access for operators to climb up and down the cab or other service areas on the crane.

8. Main boom: The main lifting component of the crane, on which the telescopic boom is mounted. It supports the main load line and is essential to the operation of the crane.

9. Boom lift cylinder: A hydraulic cylinder used to raise or lower the boom, allowing the crane to adjust the lifting angle.

10. Cab: The control center where the operator manages the movement and lifting operations of the crane.

11. Length and angle sensor: A sensor that provides real-time data about the boom extension length and angle, which is important for calculating lifting capacity and maintaining stability.

12. Counterweight: A weight installed at the rear of the crane to balance the load being lifted and enhance stability.

13. Outrigger beam: A retractable beam used to increase the base of the crane and keep it stable during operation, especially when lifting.

14. Outrigger cylinder: A hydraulic cylinder used to extend or retract the outrigger beam.

15. Outrigger pad: A pad placed at the end of the outrigger beam to spread the load of the crane over a larger area, prevent overloading the surface below and enhance stability.

Other parts of the crane are described below:

1. Anti-double pulley switch: This safety device is designed to prevent the hook pulley from colliding with the top of the boom, which could cause damage or failure to the load line. When the hook pulley reaches a preset distance from the top of the boom, it automatically stops the hoist, ensuring safe operation of the crane.

2. Wind speed sensor: Monitors the current wind speed at the location where the crane is located. This is critical to crane safety because strong winds can affect the stability of the crane and the movement of the load. Operators rely on this data to determine whether conditions are safe for lifting operations.

3. Angle sensor: Measures the angle of the boom relative to the ground. This information is critical to calculating load charts, which help operators understand the maximum safe lifting capacity of the boom at different angles and extensions.

4. Main hoist: The main lifting mechanism of the crane. It is responsible for raising and lowering the main load line, which carries the main lifting hook and load. Compared with the auxiliary hoist, it usually has a more powerful motor and a larger capacity.

5. Auxiliary hoist: The auxiliary hoist is used to handle lighter loads or for double lifting operations that handle two independent loads at the same time. Auxiliary cranes operate independently of the main crane and usually have their own hook and load line.

6. PRS 80EZ Console: This is an advanced control system or console for cranes that allows for better functionality and easier operation. It may include displays and controls for operating various crane functions, monitoring system status, and managing diagnostics.

7. Force Sensor: A sensor that measures the tension in the crane's cables or structural stress during lifting operations. This data helps ensure that the crane operates within safe load parameters to prevent structural overloads.

8. Main Hook: Attached to the main crane, this is the main hook used to lift heavy objects. It is designed to withstand the maximum lifting capacity of the crane.

9. Auxiliary Hook: The auxiliary hook is smaller than the main hook and is installed on the auxiliary hoist. It is used to lift lighter loads and allows for more delicate or precise operations.

10. Auxiliary Hoist Rope: A cable or wire rope used for the auxiliary hoist rope. It is usually lighter and sometimes shorter than the main hoist rope and is suitable for smaller or minor lifting tasks.

Understanding these components and their functions helps ensure that the crane operates safely and efficiently, adapting to various operating demands and environmental conditions. In addition, these components work together to ensure that the mobile crane can perform a variety of lifting tasks efficiently and safely.
