Prodeco Excavator RK 5000
Bucket wheel and bucket chain excavators are important products designed for mining the overburden. The most effective bucket chain excavator is marked RK 5000 and it achieves an output of 5 000 m3/h of excavated overburden.
Excavators are heavy construction equipment consisting of a boom, bucket and cab on a rotating platform (known as the "house"). The house sits atop an undercarriage with tracks or wheels. All movement and functions of the excavator are accomplished through the use of hydraulic fluid, be it with rams or motors. Their design is a natural progression from the steam shovel.
A Power shovel (also stripping shovel or Front Shovel or Electric Mining Shovel) is a bucket equipped machine, usually electrically powered, used for digging and loading earth or fragmented rock, and mineral extraction.
Shovels normally consist of a revolving deck with a power plant, driving and controlling mechanisms, usually a counterweight, and a front attachment, such as a boom or crane which supports a handle with a digger at the end. The machinery is mounted on a base platform with tracks or wheels. The bucket is also known as the dipper. Modern bucket capacities range from 8 m3 to nearly 80 m3.
Power shovels are used principally for excavation and removal of overburden in open-cut mining operations, though it may include loading of minerals, such as coal.
