6020B Hydraulic Shovel

6020B Hydraulic Shovel

When we invited our customers to help us design the first of our “Next Generation” Cat® hydraulic shovels, they gave us three top priorities: Make it safe, keep it simple and make it reliable. We responded by developing the Cat 6020B, which delivers the simplicity and versatility you desire, with valuable modern design features that set it apart from the competition.

The 6020B offers class-leading visibility and a cab designed for comfort, safety and efficiency. A walk-through and exchangeable power module contributes to easier serviceability. The 6020B is 25% more fuel efficient than other shovels in its class, delivering efficiency and cost advantages. And the proven C32 engine meets emission standards without the need for DEF, saving time and cost during maintenance.
