Detailed Tower Crane Maintenance and Care Plan for Extended Lifespan

1. Daily Maintenance

Tower Crane Lubrication:

1. Before use, inspect the lubrication status of all parts of the tower crane, including the slewing platform, telescoping boom, hoisting mechanism, and outriggers.
2. Regularly replenish lubricating oil based on usage.

Electrical System Inspection:

1. Check the wiring of the tower crane's electrical system for good connections and the status of circuit breakers for normal operation.
2. Especially in high-temperature and humid environments, more frequent inspections of the electrical system are necessary.

Wire Rope Inspection:

1. Inspect the tower crane's wire ropes for integrity and any signs of abrasion or breakage.
2. Notably, if a wire rope breaks during operation, it must be replaced immediately.

Safety Device Inspection:

1. Verify the integrity of the tower crane's safety devices, such as the load moment limiter and height limiter.
2. Regular checks of these safety devices during operation are essential.

Site Cleaning:

1. Clean the tower crane regularly to remove accumulated water and dirt.
2. During operation, avoid mortar and other substances adhering to the equipment's surface, as this can affect stability and lifespan.
3. Periodic Inspections
   1. Check the tightness of all tower crane components, such as bolts and nuts.
   2. Inspect the tower crane's running track and the condition of the reinforcing supports.
   3. Examine the degree of deformation of the tower crane's main structural components, such as the jib, counter-jib, trolley track, and base.
   4. Check the wear status of the tower crane's main components, such as tire bearings and transmission gears.
   5. Verify the normal operation of the tower crane's electrical system, including the hoist motor, transformer, and power lines.

III. Fault Handling

Mechanical Faults:

1. Mechanical faults are a common cause of tower crane failures, such as trolley track breakage or transmission system malfunctions.
2. Upon discovery, address these faults immediately to prevent disruptions to normal operation.

Electrical Faults:

1. Electrical faults are another major cause of tower crane failures, such as electrical wiring faults or control system malfunctions.
2. For electrical faults, do not attempt any maintenance or repair; contact professional personnel promptly.

In summary, regular maintenance and care are critical to ensuring the tower crane's normal operation and extending its lifespan. Adhere strictly to operating procedures during use to ensure the tower crane's safety and reliability and to minimize the occurrence of various faults.
