Autumn brings wider day-night temperature fluctuations and dry, dusty air, marking a critical window for seasonal equipment maintenance. Following the high-temperature, heavy-load operations of summer, components of KB aerial work platforms are prone to issues such as seal degradation, oil system sludge buildup, and electrical system deterioration due to moisture. Timely, specialized autumn maintenance not only addresses wear and tear from summer operations and prevents seasonal malfunctions but also facilitates early preparation for winter, ensuring continuous, stable equipment performance and extending the machine's overall service life.
The hydraulic system is a key focus of autumn maintenance. Significant temperature fluctuations during the transition from summer to autumn cause hydraulic lines and seals to expand and contract, potentially leading to hardening, micro-leaks, and other issues. A comprehensive inspection of the KB aerial work platform’s hydraulic lines, cylinder connections, and seals is required; aging or deformed seals must be replaced promptly to prevent oil leaks and pressure loss. Additionally, the quality and level of the hydraulic oil should be checked. High summer temperatures can cause the oil to oxidize, thin out, and accumulate impurities; therefore, hydraulic filter elements must be cleaned to remove contaminants. If necessary, the oil should be replaced with anti-wear hydraulic oil suitable for autumn operating conditions to ensure smooth boom lifting and rotation, preventing stalling or pressure-loss malfunctions.
The engine and fuel system require thorough maintenance. Autumn brings increased wind and dust, making air filters prone to clogging, which restricts engine air intake and reduces power; filters must be cleaned or replaced promptly to ensure unobstructed airflow. The oil-water separator should also be inspected and drained of accumulated water to prevent moisture from contaminating the fuel and affecting the powertrain. As temperatures drop, fuel should be switched to a grade suitable for the season, and engine belts should be checked for wear and tension to prevent cracking or slipping in cold weather, thereby ensuring stable power output.
The electrical system requires moisture protection and battery maintenance to ensure a reliable power supply. Large temperature differences between day and night in autumn lead to condensation, which can cause battery terminal oxidation and electrical leakage due to moisture. Battery terminals should be cleaned and coated with anti-rust grease, and electrolyte levels and battery voltage checked to ensure sufficient charge for cold-weather starting. A comprehensive inspection of the vehicle's wiring is necessary to check for damaged insulation or loose connections and to reinforce waterproofing; electrical components such as control panels, emergency stop switches, and alarm devices should be tested to ensure the electronic control system remains responsive and reliable.
Crane structural integrity and safety devices must not be overlooked. Autumn brings windy and dry conditions; therefore, it is essential to inspect steel structural components—such as the boom, outriggers, and chassis—for rust, cracks, or deformation, and to apply rust-removal and protective treatments to any exposed metal surfaces. Mud and debris should be cleared from the chassis and tire treads, and tire pressure and wear must be checked to ensure suitability for the variable road conditions of the season. Finally, a comprehensive verification of safety systems—including overload protection, tilt-induced automatic shutdown, and emergency manual pumps—is required to ensure all protective functions operate correctly and to prevent operation with unresolved faults.
Autumn maintenance focuses on seasonal inspections and proactive protection. Diligently carrying out autumn maintenance for KB aerial work vehicles effectively eliminates hidden equipment defects, ensures a smooth transition through the changing season, prepares the equipment to handle winter operations in peak condition, and guarantees continued reliability for high-altitude tasks in sectors such as electric power, municipal services, and construction.
