Filters: Check and replace air, fuel, and hydraulic filters as needed.
Battery and Electrical Connections: Inspect the battery and electrical connections for corrosion and secure fit.

4. Monthly Maintenance Tasks

The monthly maintenance tasks entail more detailed inspections and maintenance.

Hydraulic System: Conduct a thorough inspection of the hydraulic system for any signs of leakage, wear and tear on hoses and fittings, and ensure that all components are in good condition. Replace any damaged parts immediately.
Wear Parts: Thoroughly examine all wear parts, such as sheaves, cables, and slings, for any indications of excessive wear. Replace them promptly if necessary.
Structural Components: Conduct a comprehensive inspection of the boom, jib, and other structural components to identify any cracks, deformations, or other damage.
Safety Devices: Perform a comprehensive test of all safety devices, including limit switches, overload protection, and emergency stop buttons, to ensure they are fully functional.

5. Annual Maintenance and Inspections

Annual maintenance and inspections are important for reliability and safety.

Inspection: Check the crane's mechanical, hydraulic, and electrical systems.
Structural Integrity: Test the crane's structural components for hidden defects.
Overhaul: Repair and replace worn parts.
Certification: Ensure the crane meets all safety standards.

6. Lubrication and Fluids

Proper lubrication and fluid management are essential for the smooth operation of the crane:

Lubricants: Use the recommended lubricants for each component. Follow the manufacturer’s guidelines for frequency and type.
Fluids: Regularly check and change hydraulic fluid, engine oil, and coolant. Use high-quality fluids that meet the manufacturer’s specifications.
Filters: Replace filters regularly to prevent contamination and ensure optimal fluid flow

7. Electrical System Checks

The electrical system is a critical part of the crane’s operation. Regular checks include:

Connections: Inspect all electrical connections for corrosion, loose wires, and damage.
Batteries: Check the battery for proper voltage and charge. Clean the terminals and ensure they are securely connected.
Fuses and Relays: Test fuses and relays to ensure they are functioning correctly.
Control Panels: Inspect control panels for any signs of wear or damage. Ensure all controls and indicators are working properly.

8. Hydraulic System Maintenance

The hydraulic system is the heart of the crane. Proper maintenance includes:

Fluid Levels: It is essential to ascertain and maintain the correct hydraulic fluid level.

Filters: It is imperative to replace hydraulic filters on a regular basis in order to prevent contamination.

Hoses and Fittings: It is crucial to inspect hoses and fittings for leaks, cracks, and wear. Any damaged components must be replaced.

9. Structural Integrity and Wear Parts

It is essential to maintain the structural integrity and replace wear parts in order to ensure the safety and optimal performance of the crane.

Inspection: It is crucial to conduct regular inspections of the boom, jib, and other structural components to identify any cracks, deformations, or other damage.
Wear Parts: It is necessary to replace wear parts, such as sheaves, cables, and slings, when they exhibit signs of excessive wear.
Repairs: It is vital to address any structural issues in a timely manner. In the event of major repairs or modifications, it is advisable to seek the expertise of a professional.

10. Training and Documentation

All personnel must be properly trained and all maintenance activities must be properly documented to ensure effective maintenance.

Operator Training: It is imperative that operators are trained on the safe use and operation of the crane. Furthermore, regular refresher courses must be provided.
Maintenance Records: It is essential that detailed records of all maintenance activities are kept, including inspections, repairs, and replacements.

Manufacturer’s Manual: Refer to the manufacturer’s manual for specific maintenance instructions and recommendations.

11. Conclusion

Regular maintenance is the key to extending the service life of your truck-mounted crane. By following the steps and best practices outlined in this guide, you can ensure your crane remains in top condition, operates safely, and provides reliable performance.
