Which company is the wheel excavator loader durable and long-lasting

Which company is the durable wheel excavator loader? The rolling point loader increases the difficulty of moving items, improves operational efficiency, and is also an auxiliary tool in the overall loader equipment. Choosing a company with good quality and preferential prices can reduce our investment in production efficiency.

Is the double roller excavator still acceptable? The rolling axis moves upwards, and the surface is definitely relatively rough, and the work efficiency is not as good as the designer's plan. For example, if you spend 250000 yuan to buy a domestically produced machine, you can dig 3 kilometers with a production capacity of 500000 yuan later, and the actual excavation efficiency can reach about 80%. However, with the addition of double rollers and loading and unloading line operations, don't you think it's very uneconomical? I remember there was also a factory in Shandong that conducted the industry's first track test of a double roller loader. After running continuously for more than 20 hours, the result was that the machine body was scrapped, and the operating efficiency was only about 60%. Therefore, is it reflecting that only the designer has tested it, and there is no need to consider anything else.
