We all know that the excavator ripper bucket is easy to use in the destruction project. It can help us save a lot of time and greatly improve our efficiency. However, according to our understanding, many excavator masters are not very clear on how to use the excavator ripper bucket.
The excavator ripper bucket with strong excavation and cutting force, and the replaceable working device with the functions of excavation, crushing and loosening. Applicable working conditions include: excavation of asphalt pavement, hard soil, sub-hard rock, weathered stone, frozen soil, and can also be used to excavate cracked rocks.
Hydraulic quick hitch are gradually being recognized and widely accepted. In the past, it took more than 40 minutes for two people to replace accessories such as breakers.
In fact, the simpler the design of the quick-change connector, the better, the fewer parts, the lower the total weight, the better, which is easy to maintain and durable. This is basic common sense. So when we buy, we have to study all aspects of the quick-change connector before starting to buy.
There are three types of quick hitch coupler, and the functions of each type are different, so the scope of their application is also different. Here is a brief introduction to these three methods.
The orange peel grab bucket is made of special steel material, which is light in texture and high in wear resistance; the same level of large gripping force, wide opening width, small weight and high performance; built-in high-pressure hose in the oil cylinder, and the oil cylinder is equipped with a cushion pad with shock absorption function . Engineering application scope The lotus grip can work in a variety of harsh environments, and the unique jaw curve is particularly conducive to the handling of irregular materials such as scrap steel and pig iron.
Recently, we received a consultation from an excavator master about the failure for excavator boom extension. The fault phenomenon is that the front end of the boom of the excavator boom extension suddenly breaks when the bucket is filled with rocks and is lifting the boom for loading.
Reasons for cracks in the side plates of the excavator boom extension: include bubbles, slag inclusions and micro cracks in the original weld itself.
Today we will take a look at all kinds of excavators equipped with clamshell grab bucket. Because of the telescopic boom.
Clamshell grab bucket are also called sand grabs and are usually used for loading and unloading sand-like materials in railways, docks, mines and other places. However, with the emergence of telescopic booms in recent years, clamshell grab bucket have also gained new uses.
