Crane Truck-Professional Maintenance And Care in Heavy Logistics Operations

In the modern heavy logistics industry, mobile cranes serve as a critical operation tool whsoe performance and reliability are decisive for operational efficiency and safety. Regular and professional maintenance is not only a guarantee for extending the equipment's lifespan but also a key to ensuring continuous and safe operations. This article will provide a detailed introduction to the classification of moble crane maintenance and offer a series of professional maintenance suggestions.

Classification of Mobile Crane Maintenance

The maintenance of mobile cranes is divided into several levels based on complexity and frequency:

Daily Maintenance

Daily maintenance involves basic maintenance activities such as cleaning, inspection, and lubrication, carried our by operators to ensure the equipment is in good condition  during shift changes

First-Level Maintenance

First-level maintenance involves detailed inspection and maintenance of wear parts, including cleaning, lubrication, and partial adjustment, usually under the guidance of professional technical personnel

Second-Level Maintenance

Secong-level maintenance is a more rigrous inspection and repair process, involving the replacement and restoration of the crane's precision, carried our by professional

Minor and medium Repairs

Minor repairs are the least labor-intensive and invole only partial repairs,arranged by operators once every 1-2 years, including the replacement and repair of the main parts of the crane

Major Repairs 

Major repairs are the most labor-intensive scheduled repairs, including complete disassembly, inspection, repair, replacement. adjustment, and reassembly of crane into a new machine, with a fresh coat of paint or coating on the  exterior

Scheduled Preventive Maintenance

Scheduled preventice maintenance is based on the wear of parts and key components during the use of the crane, carried out regularly to maintain the performance, efficiency, and safety of the equipment

Maintenance Precautions for Mobile Cranes

Chassis Maintenance

Maintain according to the after-sales service manual at the local service station. The upper assembly should be operated and maintained according to the product use and maintenance manual provided by the manufacturer

Cleaning and Adjustment

Keep the mobile crane clean at all times, and promptly adjust and tighten loose parts to prevent increased weat or loss of parts due to loosening

Break-in Period Management

Pay attention to the workload during the break-in period, which should generally not exceed 80% of the rated workload, and arrange suitable workloads for the crane to prevent overheating from continuous operation

Fluid Management

Operators should regularly check the levels and quality of coolants, lubricants, brake fluids, hydraulic oils, and fuel(water), and pay attention to the sealing of the entire vehicle.

Instrument Monitoring

Regularly observe the indicators of the mobile crane's instruments, stop operations immediately if anomalies are detected, and cease operations until the cause of the fault is found and rectified

Maintenance After the Break-in Period

After the break-in period, enforce maintenance on the entire vehicle, perform checks and adjustments on the crane, and pay attention to the replacement of fluids

The maintenance of mobile cranes is not just a daily task but also a science. The correct maintenance methods can significantly improve the lifespan and operational efficiency of the equipment while reducing the failure rate and maintenance costs. Therefore, every operator and maintenance personnel should fully recognize the importance of maintenance and strictly follow the regulations
