Overview
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.

Benefits & Features
SAFETY
- Operator Protective Guard (Top Guard) certified cab with safety glass windshield.
- Excellent visibility thanks to cab position that provides clear view to the digging and loading areas, in-floor window that provides a view to the tracks, LED lighting, and optional camera monitoring system.
- Multiple emergency shut-off switches, including a pull switch accessible from the ground.
- Safer access and egress with wide anti-slip walkways, retractable 45-degree stairway and three means of egress for fast emergency exit.
