Abstract
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.
The development of the hydraulic system.
-
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.
