What safety issues should be noted for the tires of high-altitude work vehicles?

The tires of aerial work vehicles are an important component of aerial work vehicles, and their safety and reliability directly affect the operational safety of aerial work vehicles. In the selection, use, and maintenance of tires for high-altitude work vehicles, the following safety issues need to be noted:

Tire selection and load: Select the tire size and model suitable for high-altitude work vehicles to ensure that they can withstand the required load of the vehicle. When selecting tires, reference should be made to the recommendations of the vehicle manufacturer, and the load-bearing capacity of the tires should be matched with the actual load to prevent tire failure and accidents caused by overloading.

Tire wear and fatigue: Tire wear and fatigue can lead to a decrease in performance, increasing the risk of tire blowout and loss of control. Timely check the wear level and tread depth of the tire surface, and regularly replace severely worn tires. The fatigue life of tires is generally 3-5 years, and tires that exceed their lifespan should be replaced in a timely manner to avoid reliability issues caused by aging.

Tire pressure: The pressure of a tire has a significant impact on its operational performance and lifespan. Low air pressure will increase the frictional resistance, heat generation, and wear of tires, while also increasing the risk of tire blowout and loss of control; High air pressure can harden the tires, reduce their elasticity, and increase the vibration of the suspension system. Therefore, regularly check the tire pressure and adjust it according to vehicle usage and load conditions to maintain an appropriate pressure range.

Bulging, cracking, and damage of tires: Bulging, cracking, and damage on the surface of tires can reduce their load-bearing capacity and wear resistance, increasing the risk of tire blowout and lockup. Regularly inspect the tire tread and sidewalls for any abnormalities, such as bulges, cracks, wear, punctures, etc., and promptly repair or replace problematic tires to ensure the safe operation of high-altitude work vehicles.

Tire positioning and balance: The positioning and balance of tires have a significant impact on the stability and handling of vehicles. Regularly check the alignment of the tires, including the parallelism, toe in and toe in of the front and rear wheels, adjust the alignment angle of the front wheels in a timely manner, and maintain good steering stability. The balance performance of tires also needs to be regularly checked and adjusted to avoid vehicle shaking and loss of control caused by tire imbalance.

The usage environment and working conditions of tires: Aerial work vehicles usually work in complex environments and working conditions, and the service life and safety of tires will be affected by the environment and working conditions. For example, adverse weather conditions (such as rain, snow, ice, etc.) and workplaces (such as unevenness, blockage, flying dust, etc.) can accelerate tire wear and aging, increasing the risk of accidents. Therefore, when using high-altitude work vehicles, it is necessary to comply with relevant operating procedures, adjust the working intensity of the vehicle appropriately, and ensure that the tires operate under normal and safe working conditions.

Tire maintenance and upkeep: Regular maintenance and upkeep of tires is an important measure to ensure their safe use. This includes maintaining tire cleanliness, preventing excessive exposure to sunlight and chemical corrosion, regularly checking and adjusting air pressure, and regularly replacing severely worn tires. In addition, attention should also be paid to the storage conditions of tires to avoid the impact of adverse environments such as direct sunlight, high temperature, and humidity, in order to extend the service life and reliability of tires.
