Forklifts and concrete mixer trucks, as core specialized equipment for industrial transport and infrastructure construction, operate frequently in complex environments, often under heavy loads and continuous operation. The stability of their operation directly impacts logistics efficiency and the quality and progress of construction projects. To effectively avoid equipment failures, downtime, performance degradation, and safety hazards, major enterprises and construction units have established comprehensive, lifecycle-based maintenance systems. Through routine inspections, standardized maintenance, and professional repairs, they comprehensively improve equipment uptime and lifespan, ensuring the orderly progress of production and construction.

Forklifts often operate in high-frequency, high-intensity warehouse areas, with frequent starts and stops, heavy-load lifting, and maneuvering in confined spaces. This can easily lead to wear and tear on hydraulic lifting systems, tire wear, circuit aging, and decreased braking sensitivity. If maintenance is not timely, it can result in unstable cargo lifting, transport jams, and brake failure, affecting operational efficiency and increasing the risk of accidents such as cargo falls and collisions. In response to the characteristics of forklift operations, the maintenance team has established a tiered maintenance mechanism consisting of daily inspections, weekly maintenance, and monthly overhauls. Daily checks include hydraulic lines, braking systems, electrical and hydraulic pressure levels, and the condition of lifting components, with timely cleaning of debris from equipment surfaces. Weekly maintenance involves lubrication of lubricating components and transmission structures, and tightening of loose parts. Monthly comprehensive testing and calibration of the electrical system, hydraulic precision, and load-bearing capacity are conducted, with timely replacement of worn parts.

Concrete mixer trucks operate outdoors on complex road conditions for extended periods, with the tank continuously rotating. This can lead to issues such as tank bearing wear, seal aging, pipeline blockage, and carbon buildup in the power system. Furthermore, residual concrete material easily solidifies inside the tank, affecting mixing efficiency and finished product quality. Therefore, maintenance personnel have established a specific maintenance procedure. After each operation, the tank, unloading chute, and pipelines are subjected to high-pressure cleaning to thoroughly remove residual concrete and prevent solidification. Regular maintenance and adjustments are performed on the rotating bearings, reduction gear, and hydraulic system, checking the tank's sealing and rotational stability. A comprehensive inspection of the braking, lighting, and power systems is conducted to ensure driving safety and operational stability.

Meanwhile, dedicated operation and maintenance files are established for all equipment, recording detailed information such as operation time, maintenance records, fault handling, and parts replacement. This enables dynamic management of the entire equipment lifecycle, accurately predicts equipment wear patterns, and allows for proactive preventative maintenance. This refined and standardized operation and maintenance management model effectively reduces equipment downtime, significantly extends equipment lifespan, and reduces equipment repair and replacement costs. It comprehensively ensures the efficient, safe, and stable operation of industrial transportation and infrastructure construction, providing solid equipment support for the industry's routine production and construction.
