The First Excavator in China

XCMG 700-ton electro-hydraulic excavator

Based on the experience of supporting XCMG XE3000 mining excavator, Daming has supported XCMG XE7000 700-ton electro-hydraulic excavator as the main excavation and loading equipment for open-pit mining. The weight of this model is equivalent to 500 ordinary cars, and one shovel digs nearly 50 tons of coal, which is close to the capacity of a train wagon. The maximum thrust pressure of the bucket reaches 243 tons, and the force of the bucket bar reaches 230 tons.

It took more than 20 years to develop in foreign countries, but only seven or eight years in China. Daming is responsible for all structural parts such as upper frame, moving arm, bucket bar, turntable, bucket, diesel tank, longitudinal beam, H-frame, hydraulic tank, counterweight material, etc., and provides one-stop machining process such as cutting, edge planing, beveling, molding, machining, welding, surface treatment, heat treatment and so on.
