The timing for purchasing large second-hand excavators has slowed down transaction volume, and price reduction has become a priority

At present, the time has come for owners who want to purchase large tonnage excavatorsSince February, the trading volume of large equipment has slowed down and equipment reserves have remained relatively saturated. In just one week, the comprehensive decline in price transactions of large equipment has reached over 50000 yuan, while the price decline of 60 ton ultra large equipment has exceeded 10%. In today's world where demand is gradually shifting, large equipment is no longer in high demand as it used to be. Modifying large equipment has become one of the mainstream purchasing power at present. The modification of the extended arm and loosening hook requires modification of the equipment's large and small arms. Large scale earthworks no longer have a market in most regions of China. The economic benefits of retrofitting special equipment far outweigh those of pure earthmoving equipment. So when it's time to choose a large excavator in Huacheng, how should we choose it?

The harsh operating environment of large equipment is much higher than that of medium and small-sized machines, with a focus on earthwork in the usage site. Especially for equipment that has been installed with crushers, wear and performance losses are significant. The failure rate of such devices will continue to increase with use in the later stage. Such devices are not uncommon in the domestic market. The purchase price varies, and the key to choosing should be to carefully observe whether the equipment has been installed or broken, or whether the excavator has been modified. This can be achieved by observing whether the large and small arms are consistent with the body, and whether the small arm has been painted to cover up installation excuses. The second step is to carefully observe whether there are any signs of use at the installation site of the broken pipe in the multi way valve. Some merchants have disassembled it and refurbished it, but the spray paint on the multi way valve can be observed with the naked eye.

If there are signs of modification wear and installation during the observation of the structure of the guide wheel and chassis fighting, the equipment usage can be basically judged. The gap between the large and small arms can also be observed to determine the equipment's usage status. It can be imagined that there is a slight shaking of the small arm and obvious shaking of the small arm during rotation, as well as a gap between the large and small arms.

There are many basic judgments for large machines, especially in the observation of vulnerable parts, which requires more careful consideration of the comprehensive comparison and actual use judgment of the whole machine. If there is a component failure in the equipment during operation, it cannot be ignored. If conditions permit, choosing a large machine within five years will still provide some guarantee.
