Building on the robust and productive Cat® 5110B, the new 6015B Hydraulic Shovel delivers a productivity advantage over other 100-tonne shovels thanks to the most powerful engine in its class, a large standard bucket and payload capacity of 14.6 tonnes. The design translates to fast cycles and a pass match advantage over leading standard-equipped shovels in its class when loading trucks of 55, 65 and 90 tonne capacities.
The 6015B is equipped with a single Cat C27 ACERT™ engine that provides 606 kW of rated power. As with all hydraulic shovels, the greater the engine power, the greater the digging power and the faster the digging cycles. The large, 8.1-cubic-meter standard bucket, outfitted with Cat C70 hammerless GET, further boosts production capability. With the standard bucket, the 6015B is optimized to fill a Cat 773 truck in four passes, a 775 in five passes, and a 777 in seven passes. These truck models are commonly found in heavy construction, quarry/aggregate and small to mid-size mining operations across the globe.
The 6015B is currently available only in a backhoe configuration.
The 6015B is both powerful and efficient. Caterpillar’s proprietary integrated engine control technologies, a boom float feature that regenerates boom oil for reduced engine demand, an oil cooling system that’s independent of engine cooling, and regeneration of swing energy via its closed-loop swing system, all increase fuel efficiency.
Cat automatic flow proportioning technology creates more efficient hydraulic pump utilization, reduced energy losses and increased fuel savings. Exclusive Cat Proportional Priority Pressure Compensating technology ensures that hydraulic flow is proportional, according to demands, so individual functions—boom, stick, and bucket—are automatically prioritized during simultaneous operations. This aids smooth, efficient operation and controllability. Pressure and flow compensation deliver only as much flow as needed. The result is reduced heat build-up and component wear.
The 6015B is built upon the robust 5110B platform, proven durable and reliable. And the entire machine benefits from extensive use of proven Cat components, such as the engine, undercarriage and cab.
The 6015B front is sturdy and strong, yet light enough to promote fast cycle times. The boom and stick utilize high strength steel and rugged castings that are joined and thermally stress relieved for optimum structural life and resistance to impact and wear in difficult digging conditions. Box section design provides superior rigidity and strength, and heavy duty castings are used in high load areas to add exceptional strength and durability.
Providing superior stability, extending component life, and ultimately improving machine uptime, the 6015B swing system includes a unique cross roller bearing with sealed internal gearing, connected to an automatic lubrication system. Adding further to reliability, the undercarriage is a Caterpillar design that leverages proven Cat components.
A newly designed hydraulic filtration system has been incorporated into the 6015B design. A separate kidney loop provides continuous filtration and optimum oil cleanliness at all times, ensuring consistent oil cleanliness for dependable hydraulic system performance.
Safe and comfortable
The 6015B features well engineered access and egress with walkways for safe movement around the machine and an optional 45-degree powered access stairway. Wire and hose guarding facilitate safe maintenance. Numerous and optimally positioned lights, mirrors and E-stop buttons further improve safety.
The operator cab offers large, wide windows, which provide excellent all-around visibility of the work environment, contributing to the operator’s situational awareness during digging, loading and travel. Combined with multiple strategically positioned high-powered lights, and a heavy-duty wiper, good visibility is maintained in both dark and inclement weather conditions.
The cab is pressurized to keep dust out, and the climate control system is fully automatic, allowing for consistent in-cab temperature and operator comfort in any weather conditions. The controls are ergonomic with adjustable joystick console height, independent of the seat, to suit operator preference. And the electro-hydraulic controls provide sure, precise maneuvering.
Cat technology and support
The 6015B incorporates advanced Cat technology solutions, such as MineStar™, VIMS™ and Product Link™ for improved productivity, maintenance and equipment management. Like all Cat equipment, the 6015B is backed by the Cat Dealer Network with well-trained service technicians, unparalleled repair facilities and parts stocked around the world for fast service.

Cat® GRADE with ASSIST delivers efficiency and productivity gains to the Cat 323F L Hydraulic Excavator. This system is the first operator ASSIST feature with semi-autonomous grade control available on Cat excavators. GRADE with ASSIST automates grade adjustments that are typically achieved by the operator using manual controls. Operators at all experience levels can reach target grade as much as 45 percent faster than traditional grading.
Optimized for Cat Excavators, this new technology is easy to use from the start. Integration with the familiar Cat GRADE system, display and joysticks enables the operator to easily create simple 2D designs in the cab, press the auto button, and get to work. Operators can take advantage of the guidance features built into the base system without the need for data transfer infrastructure. For example, grade indication and audible alerts function while using ASSIST technology to perform precision work—without the need for infrastructure.
Integration with the machine and hydraulics delivers full power to the cutting edge with precise control throughout the cut, enabling the operator to create fast, accurate grades with less effort. System flexibility enables customers who work with complex grade plans to add Cat AccuGrade™ for additional 3D capability.
Automatic assistance and protection features
ASSIST technology goes to work when the cutting edge gets within 4 inches (10 cm) of target by locking onto grade and automatically adjusting boom up/down and bucket in/out movements. The operator simply controls stick speed using a single lever—significantly reducing manual inputs. The system also automates bucket movements to maintain a constant bucket angle, which is operator adjustable to match cutting angle to digging conditions and can be automatically recalled for next pass. To eliminate the chance of overcutting, a grade protection feature prevents the cutting edge from penetrating below grade—saving contractors the time and cost of rework, additional fuel, grade checking, labor hours and fill material.
In addition to helping customers speed grading, PROTECT features safeguard the operator and machine when working near obstacles and around utility hazards. Ceiling and Floor PROTECT prevent any part of the boom, stick, or bucket from going above or below a pre-set elevation— enabling the machine to excavate in areas with low ceiling heights such as indoors and under over-passes, and near above-and below-ground utilities. Operators can quickly disable AUTO control with an override trigger at their fingertips.
Features and functions
Intelligent control and protection features assist contractors in getting more work done. Functions include:
- GRADE with ASSIST – automatically adjusts boom up/down and bucket in/out to maintain constant grade.
- Operator ASSIST – operator controls stick speed using a single lever with one hand.
- Bucket Angle ASSIST– automates adjustments to maintain a constant bucket angle.
- Grade PROTECT – prevents the cutting edge from penetrating below grade.
- Ceiling PROTECT + Floor PROTECT– prevents any part of the boom, stick or bucket from going above or below a pre-set elevation.
- Operator OVERRIDE – enables the operator to override AUTO functionality.
- 2D and 3D Control – works with existing 2D grade indication system; can be upgraded to AccuGrade for 3D positioning and elevation guidance.
