The pile end resistance is directly proportional to the pile end bottom area in the same stratum. According to the premise of a constant pile diameter, increasing the bottom area of the pile end will greatly increase its end bearing capacity. In this way, the bottom-expanding drill bit is an effective technical method for improving the vertical bearing capacity and pullout resistance of a single pile.
How to transporting and handling wire ropes. Correct way: In lifting, apply the wire rope to the axle hole of the wire rope pan, or use steel pipe to penetrate the axle hole, then set the buckle on the steel pipe at both ends.
As the summer approaches, the heat will have a detrimental effect on the performance of the excavator. So, what should we pay attention to in order to maintain the performance of excavators? Besides the regular maintenance of the excavator, make sure that each component is inspected as well.
An excavator parts cylinder serves a variety of functions such as transferring power, isolating worn surfaces, reducing friction between components, suspending contaminants, controlling oxidation of component surfaces, and cooling. There are many friends who will wonder why there are iron pieces found in the excavator oil cylinder. Now, Let's explore it togethe.

Specification Power Traditional Power Bucket Backhoe Tonnage (tons) 20 Working weight of the whole machine (kg) 20200-20300 Bucket capacity (m³)
What are the disadvantages of entering water into a machine?Reduced lubrication performance: Wetness will destroy the formation of the oil film, make the oil film thinner, reduce lubricating performance, and cause a sharp increase in wear.
A lubrication system's primary function is to prevent friction between moving components. The oil circulation system utilizes a gear-type oil pump to draw oil from the oil pan. The oil passes through an oil cooler and filter prior to passing into the left and right camshaft oil galleries and main oil gallery respectively.
How to maintain your engine?1.Regular inspection and replacement of oil and oil filter.The air filter element should be checked frequently. It is impossible to blow the dust out of the outer filter element with compressed air if the outer filter element has been dusty for a long time.
