How to choose a used truck crane?

How to choose a used truck crane? Many customers have asked us about the purchase skills of used truck cranes. There are so many choices in second-hand machinery. To this end, I can only talk about some commonly used truck crane selection methods and skills.

Determine if there has been an accident

When inspecting a truck crane, you should carefully observe whether there are any traces of spray paint on the door frame and window seals of the crane. If there are still cracks in the paint marks on the door frame, you can be more sure that the door has been repaired. Secondly, you should check the welding points of the frame under the hood. The original welding points are smooth and small, and the repaired welding points are generally rougher than the original ones. Compare both sides. If this phenomenon exists, it means that the car has been compared before a serious accident. If possible, check the chassis to see the degree of aging or damage to the chassis components.

Pay attention to tires

The wear level of truck crane tires can reflect the frequent use of a vehicle, especially the front wheels. If the pattern is flat and the edges are completely free of edges and corners, it means that the original car owner works frequently and does not care much, so that the used car can be scored from one side.

observe the body

Patiently turn around the body a few more times, and carefully observe the edges of the fenders and the axles to see the degree of wear and rust of the parts. Or look at the outer end of the exhaust pipe to check for age or rust.

Pay attention to the appearance and operation of the engine

Check the appearance of the engine and carefully check for signs of oil leakage and water leakage. Light the engine and observe the color of the exhaust gas. If the exhaust gas is translucent light gray, the engine is in good condition. If it is blue, the engine is very tired. White shows that the cylinder head gasket is about to be scrapped. Also, you can sniff the smell of the exhaust, a bad smell means the engine is not in good condition.

Watch out for the brakes

Without starting the engine, first, step on the brakes a few times, and then continue to step on the brake pedal to start the car in the neutral state. If the brake pedal feels attracted, it means that the vacuum booster system of this car is normal. Be sure to test drive it, focusing on the sound of the engine and acceleration performance, whether the chassis has abnormal noise, the shock absorption effect, whether the direction and clutch are heavy, and the braking reliability.

Don’t “Lose the Big for the Small”

The most important part of a truck crane is the body, boom part and engine, and other related accessories. Second-hand cranes are more or less faulty in appearance. When you choose a crane, don’t make a fuss because of some small scratches on the appearance of the crane. The condition of the engine, boom condition, and accident are the most important things for you to choosing a second-hand truck crane. issues that should be noted.

Precautions

Generally speaking, when choosing second-hand cranes, you should try to choose those big brands and models with a large market share. Some rare imported truck cranes should be cautious even if they are in good condition and have a low price. Maybe the original owner is because of difficult maintenance and high prices. And whoever decides to cut love may not be.
