large excavator
This broad range of machines allows you to choose the type that fits your exact construction needs. With the ability to keep running for 24 hours straight, these machines have exceptional durability. Their endurance is further proven by the ultra-large excavators, which have working-time records of over 90,000 hours. This kind of performance is not surprising when you consider that our corporate policy is to never release equipment that is not field ready. We have built high user confidence and an excellent reputation over the years by realizing that, to meet the challenges of mining, our customers must have great performance.
In mining, cost efficiency is also important. excavators provide one of the lowest cost-per-ton options for moving materials in their class. Low maintenance cost and long life make for machines that give you significant savings.
Enhanced Boom Recirculation System
In combined operation of boom lower and arm, arm speed can be increased by approximately 15 % over the conventional. Pressurized oil from boom cylinder bottom side is delivered to boom cylinder rod side to lower the boom, assisted by boom weight. Conventionally, pressurized oil from pump is delivered to boom cylinder rod side to lower the boom. The new system also allows for an efficient combined operation of swing and lowering the boom.
