AGGREGATES MANAGER January 2015 32 First Built from a clean sheet design, the shovel pairs well with Cat's 777 haul trucks. ;9LK.(*(: Hydraulic Shovel C aterpillar unveiled its new 6020B hydraulic shovel before customers and the press at its Tinaja Hills proving grounds in November. With a 24-ton payload, the 247-ton unit is well matched with the Cat 777G haul trucks. "Today is a day I've waited for for a very long time," says Klaus Ukens, product manager, Cat Hydraulic Min- ing Shovels, adding that the unit boasts class-leading visibility that improves safe operations while allow- ing for ease of operation and mainte- nance. Development on the clean sheet design began in 2010 under Bucyrus and went through two transitions as that product line was acquired first by Terex, then by Caterpillar. "When we reviewed all of the cus- tomer comments, they were looking for three things: safety, simplicity and reliability," says Anita Russwurm, new product introduction manager for the 6020B. "That's what we designed and what can be seen throughout the machine." As they set out to design a unit in a new class size, Frank Tegtmeier, technical lead for the 6020B, says the team began with virtual prototyping in order to design components. Next, came finite element analysis to ensure the unit met design targets. Finally, test programs were used to ensure the shovel met its design goals. The shovel features a brand new cab. A large windshield, side win- dows, and floor window provide expansive views of the bucket and tracks as the shovel is in operation. A patented three-seat cab allows for an experienced operator to train two new operators at a time. In addition LOOK Designed to match its 777 haul trucks, the 6020B hydraulic shovel is the first Cat shovel in its size class. by Therese Dunphy, Editor-in-Chief tdunphy@randallreilly.com Payload: 24 tons Bucket capacity: 15.7 cubic yards Operating weight: 247 tons Engine: 1,043-horsepower Cat C32 ACERT Digging ranges Maximum digging depth: 26 feet, 7 inches Maximum digging reach: 52 feet, 2 inches Maximum digging height: 45 feet, 7 inches Digging forces Maximum tearout force: 146,125 pounds Maximum breakout force: 164,050 pounds 4/5 pass load: 106.9 tons 5/6 pass load: 150 tons 6020B Specs
