New Technology in Open Pit: Mining Equipment

The hydraulic excavator - backhoe and shovel, have gone through several development stages improving the economics. The two basic steps that I wish to discuss are:

1. 1.
   The development of the hydraulic system.
2. 2.
   Improvements to the attachment.

The hydraulic development has increased the utilization of the installed power. The geometrical improvements have optimized the digging ability, improving safety and reducing energy consumption.
