The new Cat® L Series medium wheel loaders—966L and 972L apply proven technologies systematically and strategically to meet our customers’ high expectations for reliability, productivity, fuel efficiency, and long service life. The new L Series medium wheel loaders are more powerful and fuel-efficient than predecessor models, featuring significant drive-train and hydraulic-system refinement, operator safety and convenience enhancements, proven Z-bar linkage, Cat Performance Series buckets, and options such as automatic traction control, enhanced ride control system, and Cat Connect Technologies.
Optional Aggregate Handler configurations offer higher payload capability for loose aggregate rehandling. These configurations enable efficient bucket size and payload pass matches to common truck payload targets and enhanced efficiency in load and carry applications.
Utilizing rigorous design and machine validation processes have delivered unmatched reliability, durability and high uptime for generations. Components used to build Cat wheel loaders are designed and manufactured to Caterpillar quality standards to ensure maximum performance even in extreme operating conditions. Heavy duty components, such as the Caterpillar designed ACERT™ engines, transmissions and axles, reduce the risk of premature wear resulting in increased uptime and reduce operating costs over the lifetime of the machine.
The 966L and 972L use the Cat C9.3 ACERT engine with maximum gross power ratings ranging from 227 to 242 kW (309 to 330 horsepower) and approximate operating weights from 23 000 to 25 000 kg (51,000 to 55,000 pounds). These power-dense engines use a combination of proven electronic, fuel-injection and air-systems.
The updated and refined Cat ACERT engines offer increased engine power by 10 percent in the 966L and 5 percent in the 972L (compared to H series) to greatly improve machine performance and response.
The 966L and 972L use a 4F/4R planetary power-shift. A high-capacity torque converter in both models uses a lock-up clutch for efficient grade and high-speed performance, and the Caterpillar Advanced Productivity Electronically Controlled (APEC) control system maintains torque flow during range shifts for faster acceleration on ramps and smoother shifts in the transmission’s direct-drive mode.
In addition, the Integrated Braking System (IBS) regulates downshifting in proportion to the required braking force, resulting in smoother downshifts and increased deceleration control. The IBS prolongs service brake life, lengthens axle-oil change intervals, reduces axle-oil temperatures, and improves transmission-neutralizer performance—resulting in faster cycles.
To expand the versatility of L Series models with work tools such as forks, grapple buckets, dozer blades, rakes, and plows, the available Cat Fusion™ Coupler System allows fast tool changes and provides performance virtually identical to pin-on tools. The coupler’s advanced wedging mechanism creates a tight, rattle-free attachment and long service life.
The machines are designed for maximum fuel efficiency and lowest fuel consumption while maintaining high performance. The new models are not only more powerful, but also feature up to 15 percent less fuel consumption compared with H Series predecessors.
The power-dense ACERT engines burn less fuel by providing power and torque when needed. Cat’s innovative powertrain, hydraulic, cooling and electronic systems intelligently lower average working engine speeds and reduce overall system heat loads resulting in significantly improved performance and fuel efficiency. Furthermore, the productive Economy Mode provides maximum fuel savings with minimal productivity impact.
Axles for the L Series models feature modifications that reduce parasitic loads and enhance positive lubrication. Available as an option, the automatic traction control system is fully automatic and requires no operator input which improves traction and reduces tire wear.
The efficient load-sensing hydraulic system features proportional flow for fast, smooth hydraulic response with optimum controllability. The system is designed to deliver more engine power to the wheels at partial hydraulic flow, allowing faster cycle times in load-and-carry and ramp operations, as well as higher rimpull when digging.
An on-demand fan further enhances fuel efficiency and lowers sound levels. In addition, the engine-idle-management and the engine-idle-shutdown systems that reduce or stop the engine after a pre-set idling interval, not only saving fuel and reducing sound levels, but also reducing hour accumulation, which helps extend service intervals and warranty.
Operator comfort and safety
The new best-in-class operator environment features four post Roll Over Protection System (ROPS) cab providing unmatched comfort, visibility, and efficiency. Seat-mounted, electro-hydraulic implement controls and programmable (in-cab) kick-outs provide optimum work-tool control, complemented by automatic cylinder snubbing that protects the machine structures and enhances performance. New, streamlined control panel includes easy to reach highly utilized machine controls to increase operator efficiency. Powerful heating and air-conditioning systems keep operators comfortable in any climate. Viscous mounts to reduce vibration and cabin sound levels.
For added safety, stair-like steps along with a large entry door to the cab reduce the angle of entry, and grab bars provide safe access to machine platforms. Floor-to-ceiling glass in the windshield, large mirrors with spot mirrors, and a standard rear-vision camera combine to provide all-around visibility. An available new ride-control system with dual accumulators allows faster cycles, improved material retention, and a smooth ride for the operator.
The front and rear frames of the new L Series models are fabricated of high-strength materials for long-term durability, robotically welded to ensure reliable performance, and designed to dissipate forces associated with aggressive loading and digging. The articulating hitch system, joining front and rear frames, provides exceptional bearing-force capacity.
Field-proven Z-bar front linkage produces optimum bucket and lift forces, and the Cat Performance Series buckets are designed to provide excellent penetration into the pile, high breakout forces, superior roll back angles, and faster cycle times, resulting in extended tire life, superior fuel efficiency, and exceptional production capabilities.
Improved hydraulic-hose routing reduces potential wear. Full-flow filtration, with additional loop filtration, protects key components and extends service life.
The one-piece tilting hood with side and rear access doors provides easy access to daily fluid level checks and fueling points and full engine compartment access when required. Electrical and hydraulic service centers provide grouped, ground-level access to such items as S•O•SSM (Scheduled Oil Sampling) ports that facilitate collecting fluid samples at optimum points in a circulating system. The new external calliper disc parking brakes are easily accessible for inspection and service. The updated cooling system is readily accessible for clean out and maintenance; the hydraulic-oil cooler and air-conditioner cores swing out providing easy access to both sides for cleaning.
Cat LINK technologies, such as the Product Link™ system, help fleet owners manage equipment utilization and lower owning and operating costs through the online VisionLink® interface, which tracks critical items, such as location, hours, fuel usage, diagnostic codes, and idle time.
Cat PAYLOAD technology, such as optional Cat Production Measurement system, accurately weighs materials being loaded and hauled to improve productivity, reduce overloading, and track material movement. Provides simple, accurate, on-the-go weighing to assist operators in delivering exact loads and working more efficiently. The intuitive user interface, within standard touch screen display, provides essential payload information in an easy-to-read, user-friendly format. Site managers can wirelessly access data via the VisionLink web portal to measure production and monitor efficiency.
Cat DETECT technology, such as the integrated rear vision camera, enhances visibility behind machine to help operators work safely.
