The new L Series medium features 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.

Reliability

The 950L and 962L use a productive and fuel-efficient Cat C7.1 ACERT engine with a maximum gross power rating of 195 (265 horsepower) and approximate operating weights from 18 000 to 19 000 kg (40,000 to 42,400 pounds). These power-dense engines use a combination of proven electronic, fuel-injection and air-systems.

According to Caterpillar, utilising rigorous design and machine validation processes have delivered unmatched reliability, durability and high uptime. 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.

Productivity

The updated and refined Cat ACERT engines offer increased engine power by 22 per cent in the 950L and eight percent in the 962L (compared to H series) to greatly improve machine performance and response.

The 950L and 962L use a 5F/3R countershaft power-shift transmission. 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.

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.

Fuel efficiency

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 10 percent less fuel consumption for the 950 and 962L 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.

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.

Technology

Cat LINK technologies, such as the Product Link™ system, help fleet owners manage equipment utilisation 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. It 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.
