Maintenance and Upkeep of Truck-Mounted Cranes: How to Maintain Truck-Mounted Cranes

The truck-mounted crane is a specialized vehicle, and as such, its operators should undergo guidance and training from the manufacturer. They need to have a comprehensive understanding of the structure and performance of the entire vehicle and acquire a certain amount of operating and maintenance experience of the truck-mounted crane from the manufacturer before commencing operation. The product operation and maintenance manual provided by the manufacturer serves as an indispensable resource for the operators of the truck-mounted crane. Before operating the equipment, it is imperative to thoroughly read the operation and maintenance manual of the truck-mounted crane and conduct operations and maintenance in accordance with its stipulated requirements.

The operator should be diligent in frequently checking the coolant, lubricating oil, brake fluid, hydraulic oil, and fuel oil (water) level and quality. Simultaneously, attention should be given to inspecting the sealing performance of the entire vehicle. The requirements for the use and maintenance of the truck-mounted crane during the running-in period can be summarized as follows: reducing the load, enhancing lubrication, intensifying training, and focusing on inspection. As long as the operator attaches significance to and adheres to the maintenance and upkeep of the running-in period of the truck-mounted crane as stipulated by the manufacturer, the occurrence of early faults of the truck-mounted crane can be mitigated, its service life prolonged, operational efficiency enhanced, and the truck-mounted crane can bring about maximum benefits. Concurrently, the lubrication of each lubrication point of the truck-mounted crane should be reinforced. It is recommended that during the running-in period, the lubrication points be replenished with grease in each shift, except in cases where there are specific requirements to the contrary.

Consequently, during the running-in period of the truck-mounted crane, component wear (particularly on mating surfaces) is prone to occur, and the rate of wear is relatively rapid. At such times, if overloaded operation is carried out, it may result in component damage and give rise to early faults of the truck-mounted crane.

The lubricating oil of the truck-mounted crane, the coolant of the truck-mounted crane, the brake fluid of the truck-mounted crane, the hydraulic oil of the truck-mounted crane, and the fuel grade and quality utilized by the truck-mounted crane, among others, all require close attention. Fuel is a particularly critical aspect for special vehicles. Due to the specialized nature of the vehicle, the use of fuel must guarantee that the purity and grade of the fuel comply with the driving and operational specifications. It is not advisable to mix water with the lubricating oil of the truck-mounted crane. The coolant needs to be replaced at regular intervals. The lubricating oil is typically changed approximately once every quarter.

Let’s elaborate on the importance of these fluids. The lubricating oil plays a vital role in reducing friction and wear between moving parts within the truck-mounted crane‘s systems. A proper grade and quality of lubricating oil ensure smooth operation and longevity of the components. The coolant helps regulate the temperature of the engine and other heat-generating components, preventing overheating and potential damage. Brake fluid is essential for the effective functioning of the braking system, ensuring reliable stopping power. Hydraulic oil is crucial for the smooth operation of the crane’s hydraulic systems, enabling precise and safe lifting operations.

The maintenance of a newly purchased truck-mounted crane presents more challenges compared to that of a truck-mounted crane with a certain mileage or driving age. The new vehicle undergoes a running-in period during which both the vehicle and the driver need to adapt and familiarize themselves with each other. For aspects such as the load capacity of the truck-mounted crane, driving speed, and detection of abnormal vehicle conditions, time and attention are required for vigilant monitoring and comparison. Strengthening the lubrication of the truck-mounted crane can guarantee the harmonious operation among the various apparatuses of the vehicle. After a period of running-in, the maintenance of the truck-mounted crane becomes relatively more straightforward.

During the initial stages, the driver needs to be particularly observant of any unusual sounds, vibrations, or performance deviations. This early detection and prompt addressing of potential issues can prevent minor problems from escalating into major faults. Regular checks of fluid levels, tire pressure, and component tightness are essential to ensure the vehicle remains in optimal condition.

The crane is the core component of the truck-mounted crane. If there are any issues with the crane, the truck-mounted crane essentially reduces to just a transport vehicle. Therefore, the maintenance of the crane of the truck-mounted crane demands heightened attention. The crane requires regular lubrication treatment to prevent dry wear of its components. Selecting standard models for the hook and hoisting rope of the crane is of utmost importance. When conducting hoisting operations, it is essential to strictly adhere to the operating specifications. Incorrect operation methods can readily lead to damage of the crane of the truck-mounted crane.

For example, a poorly maintained or incorrectly operated crane can result in reduced lifting capacity, inaccurate positioning, or even safety hazards. Regular inspections of the crane’s structure, mechanical components, and electrical systems are necessary to identify any signs of wear, fatigue, or malfunction.

Once the running-in period of the truck-mounted crane concludes, mandatory maintenance should be carried out on the entire vehicle. This involves conducting a comprehensive inspection and adjustment of the truck-mounted crane while paying close attention to the replacement of oils. The requirements for the use and maintenance of the newly purchased truck-mounted crane during the running-in period can be summarized as: reducing the load, strengthening lubrication, paying meticulous attention to operation, and conducting thorough inspections. The operator’s emphasis on and execution of the maintenance and upkeep of the running-in period of the truck-mounted crane as stipulated by the manufacturer can effectively alleviate the negative impact of the running-in period on the performance and lifespan of the truck-mounted crane.

Proper maintenance and care during the running-in period lay a solid foundation for the long-term reliable operation and efficient performance of the truck-mounted crane. It not only reduces the likelihood of breakdowns and costly repairs but also enhances the vehicle’s overall value and safety.

In conclusion, maintaining a truck-mounted crane requires a combination of regular inspections, adherence to manufacturer guidelines, and the use of quality fluids and components. By taking these measures, operators can ensure the longevity, performance, and safety of their truck-mounted cranes, maximizing their investment and operational benefits.
