The truck-mounted crane, as an integral member of the special vehicles family, has made substantial contributions to China’s modernization endeavors. Currently, the sales of truck-mounted cranes in the market are highly prosperous. Once you acquire a truck-mounted crane, maintenance undoubtedly becomes an indispensable aspect. With appropriate maintenance measures in place, the service life of the vehicle can be significantly prolonged, and the economic benefits we can obtain can be more substantial. On the truck-mounted crane transporter, tires stand out as one of the crucially important components, and their maintenance holds significant importance. During regular usage, paying meticulous attention to certain details can effectively safeguard the tires.
Firstly, let’s focus on the tire pressure of the truck-mounted crane. The tire pressure is intricately linked to the fuel consumption of the entire vehicle. When the tire pressure is maintained at a normal level, the driving resistance presented by the tires is relatively low, resulting in reduced fuel consumption. If the tire pressure drops too low, the wear on the shoulder area of the truck-mounted crane tire intensifies. This excessive wear can compromise the tire’s structural integrity and longevity.
Let’s delve deeper into this aspect. A low tire pressure causes the sidewalls of the tire to flex more than usual, concentrating the stress on the shoulder region. This not only leads to accelerated wear but also increases the risk of tire failure, especially under heavy loads or high-speed conditions.
Conversely, if the tire pressure is too high, the grounding area of the truck-mounted crane tire shrinks, causing the unit pressure to escalate. This increase in pressure results in heightened friction in the middle of the tire tread. Simultaneously, it augments the rigidity of the tire, elevating the dynamic load on the wheels and creating a heightened risk of tire carcass rupture.
High tire pressure can also adversely affect the vehicle’s handling and ride comfort. It reduces the tire’s ability to absorb shocks and vibrations from the road surface, transmitting these forces directly to the vehicle’s suspension and chassis components.
Regularly inspecting the appearance of the tires is of paramount importance. Ordinarily, pay close attention to whether there are any cracks, deformations, or other defects manifesting on the surface of the tires. The tread grooves of the tires on the truck-mounted crane undergo wear and gradually become shallower due to prolonged usage. If they are worn smooth, they lose their crucial functions of effective drainage and skid resistance, consequently leading to a decline in the various performance aspects of the vehicle.
If small fine lines appear on the tires, the probability of a tire blowout during high-speed driving escalates significantly. These fine lines are often an indication of internal damage or aging of the tire structure, weakening its ability to withstand the stresses and temperatures encountered at high speeds.
It is highly advisable to select a flat surface for parking. The truck-mounted crane should refrain from parking on roads strewn with sharp stones, and it is best to keep a safe distance from substances such as petroleum products, acidic materials, and other elements that can accelerate the deterioration of rubber. Additionally, avoid turning the steering wheel after parking, as this action can accelerate tire wear.
Parking on uneven or rough surfaces can cause uneven stress distribution on the tires, leading to premature wear and potential damage. Sharp stones can puncture or nick the tires, while exposure to harmful substances can degrade the rubber compound, reducing the tire’s durability and performance.
Avoid sudden braking at all costs. Many a time, we come across long tire marks on the road, which are typically the aftermath of sudden braking. Such an action is extremely detrimental to the tires. The truck-mounted crane should also strive to minimize sudden braking as much as feasible. Sudden braking not only subjects the tires to excessive wear but also escalates the wear of the brake pads.
The force exerted during sudden braking can cause excessive heat build-up within the tire, potentially damaging the internal structure and reducing the tire’s lifespan. It also places additional stress on the braking system, increasing the likelihood of component failure and requiring more frequent maintenance or replacement.
Poor tire performance has a cascading impact on the entire vehicle. In truth, regardless of whether it is a truck-mounted crane or other vehicles such as mixer trucks and wrecker trucks, meticulous tire maintenance efforts should be consistently carried out.
Proper tire maintenance involves not only the aspects mentioned above but also includes regular rotation of tires to ensure even wear, maintaining the correct wheel alignment to prevent abnormal tire wear patterns, and replacing tires when they reach their recommended service life or show signs of significant deterioration.
By giving due attention and care to tire maintenance, vehicle owners can enhance safety, improve fuel efficiency, optimize handling and performance, and ultimately reduce overall operating costs and extend the lifespan of their valuable assets on the road.
