40-ton excavator purchasing guide: Should you choose a new machine or a second-hand machine?

In the field of construction machinery and equipment, large excavators, especially those at the 40-ton level, have never been targeted at the civilian market. Of course, most individual users are used in contract engineering projects, so most of them can use large construction machinery and equipment, especially for excavation. The machines are mostly used in larger engineering projects or company purchases, which means that product performance and usage efficiency receive the focus of users.

Faced with the dazzling array of brands and models on the market, how do we choose a large excavator with powerful performance, stability and reliability, and a reasonable price? TD recommends several products for you and several advantages of buying a second-hand excavator.

First of all, the price of a second-hand excavator is only between 20-60% of a new one. Taking into account the use time and equipment loss, it is usually recommended for novices or those entering the industry to use equipment of recent years. This type of model can basically reach the peak level of mechanical quality, but the price is on the high side, so 3- Equipment that is 8 years old or above can still perform efficiently as long as it is well maintained and maintained. Usually, the service life of an excavator equipment can exceed 20 years.
