Summer's high temperatures, heavy rainfall, and dust make it a peak season for malfunctions in aerial work platforms. Prolonged exposure to sunlight, high temperatures, and rain can easily cause hydraulic systems to overheat, wiring to become damp, and components to age faster, directly impacting operational safety and construction efficiency. To ensure stable output and minimize downtime for KB aerial work platforms under high-intensity summer conditions, proper seasonal maintenance is crucial.
Engine System
High temperatures put significant pressure on engine cooling, making it prone to overheating, power loss, and other problems. Regularly check the coolant level, concentration, and cleanliness, and replenish or replace with summer-appropriate high-boiling-point antifreeze to ensure smooth cooling circulation. Clean the water tank and radiator surface of catkins, dust, and debris to prevent blockages and poor heat dissipation. Additionally, check the engine belt tension; replace belts immediately if hardened or cracked, and shorten the air filter inspection cycle to prevent dust from entering the engine and causing wear.
Hydraulic System
High summer temperatures reduce hydraulic oil viscosity, leading to unstable oil pressure, sluggish operation, and excessively high oil temperature. Regularly check the hydraulic oil condition; replace it immediately if it turns black, thins, or emulsifies. Keep the hydraulic oil tank and radiator clean and free of dust to ensure effective cooling. Thoroughly inspect hydraulic lines, seals, and joints; high summer temperatures can cause rubber lines to age and soften, leading to leaks and pressure drops. Replace any damaged lines immediately to ensure smooth and precise boom lifting and rotation.
Electrical System
Summer brings frequent thunderstorms and high humidity, making the wiring, batteries, and control boxes of aerial work platforms susceptible to moisture and oxidation. It is necessary to clean the battery terminals to prevent oxidation and leakage, check for aging or damage to the wiring insulation, tighten loose connections, and ensure proper waterproofing. Regularly test the emergency stop system, alarm devices, and control panel lights to ensure the electrical control system is sensitive and reliable, preventing electrical faults during rainy weather operations.
Safety Devices
Summer operations are frequent and demanding. Each safety component, including the work platform guardrails, safety locks, tilt protection, overload alarm, and emergency manual pump, must be thoroughly inspected to ensure all protective functions are normal and effective, preventing operation with defects.
The core of summer maintenance lies in cooling, dust prevention, moisture prevention, and anti-aging. Standardized implementation of the key points for summer maintenance of KB aerial work platforms can effectively reduce equipment failure rates, maintain stable equipment performance, and ensure safe, efficient, and continuous operation for various high-altitude operations such as construction sites, power plants, and municipal projects.
