The brand new Cat 6015 hydraulic mining shovel has been upgraded with enhancements in machine uptime, working effectivity and sturdiness leading to greater annual shovel output.
“We’ve given the brand new 6015 class-leading device carrying capability and heavy-duty undercarriage safety to ship dependable and productive operation in essentially the most demanding circumstances,” says Ryan Mitchell, product worth stream supervisor. “With its 14.6-tonne bucket payload, the shovel offers confirmed move match effectivity with Cat 773, 775 and 777 haul vehicles working within the 55- to 90-tonne-class (61- to 100-ton-class) vary. It delivers versatile and productive loading effectivity throughout a full spectrum of functions, together with mining, quarry and combination, heavy development, and industrial.”
The shovel’s 615kW (824hp) Cat C27 engine includes a new maintenance-free, non-selective-catalytic-reduction aftertreatment answer that doesn’t require diesel exhaust fluid (DEF) to fulfill U.S. EPA Tier 4 Ultimate/EU Stage V emissions requirements.
Two various engine configurations can be found for areas with decrease emission requirements – one assembly China Nonroad Stage III requirements (equal to U.S. EPA Tier 2) and a second, fuel-consumption-optimized U.S. EPA Tier 1 emissions equal.
Somewhat than delivering a set quantity of oil at excessive idle, the shovel’s new technology pilot pump configuration provides variable, on-demand hydraulic oil circulate based mostly on management lever actions.
In intervals of simultaneous machine actions, the pump will increase circulate, and when joysticks are returned to impartial, oil circulate decreases. This lowers system warmth technology, reduces element put on and improves gas effectivity by a minimal of 5.5%.
A brand new Cat Proportional Precedence Strain Compensating (PPPC) hydraulic system will increase operator effectivity by various hydraulic circulate straight proportional to joystick actions for clean, predictable operation.
Caterpillar’s four-pump system discovered on the 6015 dedicates three pumps to implement and journey and one to swing. Strain and circulate compensation ship solely as a lot circulate as wanted. When circulate is required by a couple of perform, automated circulate proportioning delivers exact multifunction operation.
Growth-lowering float valves present quicker actions by utilizing gravity, quite than hydraulic pumps, to decrease the increase and enhance effectivity, permitting the pumps to help different features concurrently. Enhancing power effectivity whereas producing much less warmth, the 6015’s closed-loop swing system feeds captured swing movement kinetic power again to the system throughout deceleration, offering extra energy to drive the principle and auxiliary pumps.
Retrofittable to earlier designs, a brand new heavy-duty undercarriage safety bundle options long-life elements and body to extend machine uptime. Heavy-duty idlers and rollers plus enhancements to trace pads, monitor tensioning, and put on quantity add to elevated undercarriage sturdiness and reliability.
Withstanding harsh mining circumstances, rugged entrance attachments are designed with high-strength metal and castings, joined and thermally stress-relieved to increase service life and obtain manufacturing targets.
The 6015’s new customary bucket linkage autolube system eliminates the necessity for guide lubrication. For clean operation and elevated sturdiness, the brand new slew bearing incorporates a triple curler design. A capability enhance for the brand new customary grease tank offers 500-hour service intervals.
The brand new shovel connects to straightforward Cat MineStar Options with new Product Hyperlink Elite by both a mobile or satellite tv for pc connection, and MineStar Well being provides expanded situation monitoring and reporting to fleet operations. Cat Digital Technician (ET) permits service technicians to successfully diagnose and execute engine upkeep and monitor new pilot pump system stress.
Its design affords simpler entry to the engine compartment, superstructure elements and ground-level service station for safer and extra streamlined serviceability. Extensive, anti-slip walkways with restricted elevation adjustments, minimised journey hazards, and an elective powered 45 diploma stairway enhance entry, egress and motion concerning the shovel safely.
