A new engine has given the Cat 6020 hydraulic mining shovel a boost, delivering on high uptime and increased efficiency.
The engine has been replaced with a new Cat C23B to offer more reliable and durable operations. No additional hardware is required for the engine replacement, offering the same 776 kilowatts rated power as its predecessor.
A higher flow oil and baffles in the oil cooler keep the engine core cooled, while the new cylinder head maximises heat transfer.
In an effort to increase reliability, a thicker shim gasket reduces the risk of head-to-block oil leaks. More durable exhaust valves, especially when operating at high power, reduce the chance of exhaust valve failures.
“Hydraulic optimisation for the 6020 shovel dynamically assigns individual pumps or groups of pumps to deliver the exact flow and pressure required by each hydraulic function,” Cat said.
“Reducing waste and excess heat buildup, hydraulic optimisation provides efficient use of the engine for greater productivity, less energy and fuel consumption, and reduced component wear.
“With its 22-tonne payload, the 6020 efficiently loads the Cat 775 truck in three passes, 777 in four passes, 785 in six passes and 789 in eight passes.”
Designed for operator comfort, the next generation cab on the 6020 offers visibility for operating productively, safely and efficiently.
“Electronic-hydraulic servo joystick control delivers fast and precise machine movements with less operator fatigue, while five-circuit hydraulics allow for simultaneous control of two cylinder motions, two travel motions and swing,” Cat said.
“The large 254mm high-definition colour touchscreen puts all vital machine and diagnostic data at the operators’ fingertips.”
