Under normal circumstances, the chain elongation of 1/50 is normal when working, if excessive elongation will reduce the number of teeth of the sprocket, resulting in noise and damage to the chain. The elongation of the chain can be reflected by the sag value L of the loose edge. The L value is generally 2 to 4% of the center distance between the two sprockets, and when the sag is excessive, the sprocket cover should be removed and adjusted with a tensioning device. Sleeve roller chain will stretch at work, which is due to the wear between the sleeve and the roller caused by the gap, so to use the thinner lubricating oil into the chain plate gap, the oil should be on the loose side of the chain, so that the oil into the chain plate gap, and then use cotton yarn to wipe off the excess oil, do not use butter or high-viscosity oil on the chain lubrication. That would damage the chain and sprocket by sticking to the dust. Excavator training believes that if the chain is seriously contaminated, it should be removed and cleaned with gasoline, placed in the lubricating oil for half an hour, and then fished out to wipe off the excess oil and continue to load the car. The drive chain is also the final transmission component of the road roller, and its transmission load is very large, and it is affected by the impact of driving and braking, and needs to be carefully maintained。

Excavator is a multi-functional self-propelled mechanical equipment, according to different work needs and terrain characteristics, can be tracked, wheeled or walking and other types. The main structure consists of a superstructure with a 360° rotating working device for digging and handling materials, loading them into transport vehicles or unloading them to the storage yard.   Excavators can be divided into several categories according to tonnage and use scenarios:   Large excavator: suitable for large-scale mining and large-scale earthwork.   Large excavators: mainly used in large infrastructure construction and mining operations.   Medium excavator: Used in medium engineering projects and construction sites.   Small excavator: suitable for small construction sites and urban construction projects.   Mini excavators: Used for work in small Spaces, such as municipal maintenance and landscape engineering.Affected by the epidemic and geopolitical factors, the global economic slowdown has led to the impact of China's infrastructure construction and engineering construction industries, and the demand for the excavator industry has been greatly reduced. According to 2023 data, China's excavator sales reached 195,000 units, down 25.4% year-on-year, continuing the downward trend in 2022. However, due to the promotion of a series of foreign development policies in China, the amount of foreign projects contracted in China has increased year by year, which has prompted the export volume of excavators to also increase rapidly, partly alleviating the pressure of insufficient demand in the domestic market.   The position of Chinese excavator enterprises in the global market is gradually improving, especially in Asia, Africa and South America, and the demand is increasing. This is mainly due to the high cost performance and perfect after-sales service system of Chinese brands, which makes the excavator maintain stable growth in the international market.

1. Market sales in the second half of the year: From the current trend of the real estate market, the construction area and new opening area of the real estate market in the second half of the year will still fall, which is difficult to drive the market demand for related machinery and equipment.       However, with excavators as a barometer, the construction machinery industry has once again entered the equipment renewal cycle. In the second half of the year, the small excavators that took the lead in entering the renewal cycle will continue to pull the overall sales of excavators to continue to rebound.       At the same time, under the promotion of large-scale equipment renewal policies around the country, nearly one million old excavators below the second and more than ten years will be gradually phased out. Although, due to the downturn in the downstream market such as real estate, most of the old excavators have no replacement demand, but the huge stock of equipment is cleared, which is conducive to repairing the supply and demand relationship in the rental market.       Based on this, it is expected that the excavator market will maintain a growth rate of about 20% in the second half of the year, and it is expected that the domestic excavator sales will exceed 100,000 units in the year, an increase of about 15%.       2. Agent development: As small mining takes the lead in entering the update cycle, the proportion of small mining sales continues to increase. This is not good news for agents.       On the one hand, in order to ensure market share, most agents sell small mining machinery at a loss, and the more they sell, the greater the loss; On the other hand, because small mining customers are more fragmented and more mobile, the gap between the marketing coverage cost of small mining machinery and the three guarantees service cost is not obvious.       At the same time, for agents, there is little business to do after the market demand for small mining models such as parts and maintenance. However, the debt risk of small mining sales is relatively low, the legal machine repurchased by agents is also relatively easy to dispose of cash, and the overall debt risk control exposure is better than that of large mining.       Therefore, it is expected that the operating profit of agents in the second half of the year will continue to deteriorate. However, the increase in small mining sales and the acceleration of the issuance of special bonds in the second half of the year are expected to ease the pressure on the operating cash flow of enterprises.In addition, due to the rising proportion of small mining sales, the market share of joint venture/foreign brands will still be eroded and squeezed by domestic brands.       In summary, although from the data point of view, the excavator market has bottomed out, but even if the domestic sales of more than 100,000 units this year, it is difficult to correct the imbalance between excess capacity and market demand, the price war will not go away, and most agents and leasehold "days" are still suffering. Oems can rely on the sea to "replenish energy", and agents can rely on what?
