A new wave of strong cold air continues to expand its reach, bringing significant temperature drops and rain/snow weather to many regions. Under complex conditions such as low temperatures, humidity, and icing, the operational safety and equipment condition of aerial work platforms face heightened demands. To ensure winter outdoor operation safety and extend equipment lifespan, this guide systematically outlines key winter usage and maintenance points based on the structural characteristics and practical experience of aerial work platforms, for user reference.
I. Whole-Machine Inspection A comprehensive whole-machine inspection must be conducted before each use of the aerial work platform. This inspection should cover not only the external condition but also key structural and system components to ensure the equipment is in good working order. Pay particular attention to any abnormalities such as loose parts, deformation, or leaks. After starting the vehicle, observe the electrical system's operational status to confirm normal instrument readings and the absence of fault alerts, avoiding operation with existing faults. II. Hydraulic System Inspection The hydraulic system is the core component enabling lifting and motion control in aerial work platforms, requiring particular attention under low winter temperatures. Verify that the hydraulic fluid level is adequate and inspect the oil for signs of emulsification or degradation. In extremely cold environments, use a hydraulic oil grade suitable for low-temperature operation, typically requiring a minimum temperature rating of approximately -15°C. Only by ensuring both the quality and quantity of hydraulic fluid can its proper flow at low temperatures be maintained. This provides effective lubrication for moving parts, reduces wear, and ensures smooth overall operation.
III. Engine and Power System Inspection Before winter use, focus on checking the type and level of engine coolant and oil to ensure they meet low-temperature requirements. Simultaneously, verify that the oil-water separator has been drained promptly to prevent water from freezing at low temperatures and affecting the fuel supply system. The intake system must remain unobstructed to prevent debris or ice from restricting airflow. Furthermore, verify the battery charge is sufficient, with a static voltage recommended above 12.3V to ensure reliable starting capability in cold conditions. IV. Vehicle Starting Precautions In cold weather conditions, perform necessary preheating before starting the vehicle and confirm the preheating system is functioning properly. After the initial start, allow the engine to idle for approximately 5 minutes to gradually warm the engine oil and hydraulic fluid before commencing operations. When ambient temperatures fall below -10°C, multiple preheating intervals may be performed as needed, but avoid frequent starts within a short period to prevent additional strain on the starting system and battery. Winter operating conditions impose heightened demands on the safety and reliability of aerial work platforms. Through standardized pre-operation inspections, targeted system maintenance, and proper starting procedures, risks associated with low-temperature environments can be effectively mitigated. This ensures stable equipment operation, providing a solid foundation for efficient and safe winter construction.
