Excavators weighing more than 30 tons or more are mostly not used in cities in working environments and types of work. They are mainly used in mines, large-scale infrastructure and mining projects. Moreover, it is understood that most users are very demanding when choosing large-scale construction machinery. Considering the long working distance, maintenance and repair are very troublesome, the stability and low failure rate of the equipment are the important conditions for choosing it. Today, Tiedou has used excavators to introduce 4 Caterpillar excavators over 30 tons. Among them, CAT330 is divided into regular version and GC version to meet the needs of different users.
From the parameters and performance, the GC version of CAT330 is first of all lower in price than the regular version. Although both are equipped with Cat C7.1 ACERT engines, the difference in power also means that the working performance has certain differences. Why does Caterpillar sacrifice performance? It is mainly considered that large-scale projects are divided into projects with different performance types such as earthwork or rock. The GC version meets the use of construction sites with low performance requirements, plus low fuel consumption, low price and limited budget users or enterprises. The conventional version unleashes the full potential of the Cat C7.1 ACERT engine and is suitable for harsh environments and heavy engineering projects. The following is a price reference for the different performance parameters of the two Caterpillar CAT330 models.

It can be said that the working performance of the new excavator has indeed been significantly upgraded. Large-capacity work will bring greater loads to the excavator and cause excessive wear, and it needs to be used according to its own requirements and work type to avoid damage.

Caterpillar CAT340 series has a significant upgrade span. The engine is upgraded to C9.3 with a power of 232Kw. Compared with the above four models, 340 is very outstanding in terms of size and performance at this level. There may not be much difference in performance compared with other brand manufacturers, but in the actual working environment, the working performance of CAT340 series can lead many international brands. We still highly recommend the 340 series excavator Tiedou for users who pursue performance. Considering the slightly higher price, users with budget requirements can choose Caterpillar's previous generation of used excavators, which have excellent reputation, stable performance and very cost-effective price.

Different excavator manufacturers have different technologies and target customer groups. Excavator manufacturers over 30 tons have more stringent requirements for stability and service life. According to incomplete statistics, the perfect working time of a large excavator is 15,000 hours/10 years. As the structure ages and deforms, wear is accelerated. Although it is not visible to the naked eye, the longer the use time, the higher the parts need to be replaced and the higher the maintenance cost, but the maintenance of workers can greatly extend the service life. 10-20 years can still play 90% of the functions of the excavator. Although there are many excavators over 20 years old, they are gradually eliminated with the increase in costs and the country's strict requirements for environmental protection. However, it must be said that the main reliability of used excavators is still more popular with users in terms of complete performance and price.
