The truck-mounted crane, which combines hoisting and transportation functionalities and is also referred to as the truck-mounted crane transporter, might witness some drivers being rather lackadaisical when it comes to vehicle maintenance. In reality, accurate maintenance and proper usage can effectively postpone the “aging” process of the vehicle. Today, the editor will impart to you some valuable minor knowledge regarding the maintenance and repair oftruck-mounted cranes.
The principal aspects encompassed in the maintenance and repair of truck-mounted cranes involve lubrication, anti-corrosion measures, cleaning operations, adjustment of components, and their replacement, among others. Generally, the maintenance and repair of truck-mounted cranes can be categorized as follows:
Daily maintenance: This pertains to the external upkeep of the truck-mounted crane, such as cleaning, conducting inspections, and refueling. It is carried out by the operator and constitutes one of the elements during shift handovers.
Let’s elaborate on this aspect. Daily cleaning helps remove dirt, debris, and contaminants that can accumulate on the surface of the vehicle, not only enhancing its appearance but also preventing corrosion and damage to components. Regular inspections allow for the early detection of minor issues like loose fittings, leaks, or signs of wear and tear. Timely refueling ensures that the vehicle has an adequate supply of fuel for smooth operation.
First-level maintenance: This involves inspecting and maintaining the vulnerable components of the truck-mounted crane. It includes tasks such as cleaning, lubricating, undertaking partial and key disassembly and adjustment of the truck-mounted crane, and is typically executed by the operator under the guidance of full-time maintenance personnel.
During the first-level maintenance, close attention is paid to components that are prone to wear and tear or malfunction. Lubrication helps reduce friction and extends the lifespan of moving parts. Disassembly and adjustment ensure that these components are operating within the correct parameters and specifications.
Second-level maintenance: This entails a rigorous inspection and repair of the truck-mounted crane. It encompasses activities like replacing components, restoring the accuracy of the truck-mounted crane, and is carried out by full-time maintenance technicians.
Here, more in-depth inspections and repairs are conducted. Components that have reached the end of their service life or have significant damage are replaced to ensure the optimal performance and safety of the vehicle. Accuracy restoration ensures that the crane operates precisely as per the design specifications.
Minor repair: This represents a localized repair involving the least amount of work, merely encompassing local repair, replacement, and adjustment.
For instance, if a specific component shows minor damage or malfunction, a minor repair focuses on addressing that specific area without extensive disassembly or major overhauls.
Medium repair: This is a planned repair entailing a relatively substantial amount of work. The operator typically arranges it once every 1-2 years. The content includes replacing and repairing the main parts of the truck-mounted crane, inspecting the entire vehicle, and conducting adjustments and calibrations to ensure the truck-mounted crane complies with the requisite technical standards.
During a medium repair, key components that have experienced significant wear or potential issues are replaced or repaired. Comprehensive inspections help identify any hidden problems and ensure the overall performance and safety of the vehicle.
Overhaul: This is a planned repair involving the largest amount of work. It includes a complete disassembly, inspection, repair, replacement, and adjustment of the truck-mounted crane. Finally, the vehicle is reassembled into a new, complete unit, and its exterior is repainted or plastered. It is usually conducted only once every approximately four years and can be accomplished by a professional (repair and fitting) factory.
An overhaul is a comprehensive and in-depth process that rejuvenates the entire vehicle, ensuring it operates at peak performance and meets all safety and technical requirements.
The above-mentioned minor maintenance knowledge is provided for the reference of truck-mounted crane drivers!
It’s essential for drivers to adhere to these maintenance and repair schedules and procedures to prolong the lifespan of the truck-mounted crane, enhance its performance, and ensure safe and efficient operations. By giving due attention to maintenance, drivers can minimize the risk of breakdowns, improve productivity, and protect their investment in the vehicle.
