What's New In Plant & Equipment

Cat’s More Powerful 950L and 962L Medium Wheel Loaders - continued

Cat’s More Powerful 950L and 962L Medium Wheel LoadersThe 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.

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.

Operator comfort and safety

The new operator environment features four post Roll Over Protection System (ROPS) cab providing superior 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.

Durability

The front and rear frames of the new 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.

New Cat Tilt BucketsNew Cat Tilt Buckets

A new line of Cat tilt buckets is available for Cat crawler-excavator models 311-325 and for wheel excavator models M314–M322. The new buckets, available in both pin-on and coupler configurations, hydraulically tilt 45 degrees from vertical, right and left, to provide added capability when working on angled surfaces or performing precise grading.

The buckets install easily and are designed for such applications as ditch cleaning, landscaping, and various construction tasks. In addition, the buckets can be used for conventional excavating in low-impact soils, including top soil and clay.

The tilt buckets are equipped with two horizontal cylinders—sized to provide forces matched to the machine—that allow the operator to position the bucket and maintain grade without moving the machine. The horizontal-cylinder design allows a low-profile for the bucket, while protecting the cylinders from material flow.

The new buckets are drilled and tapped to accept the bolt-on sensor and clips required to make them “plug-and-play” compatible with Cat Grade Control 3D. Grade control provides visual and audio positioning guidance for the operator via the machine’s in-cab monitor, enhancing the speed, accuracy, and material-movement efficiency of excavating and grading tasks.

Tilt buckets feature a reversible, wear-resistant, bolt-on cutting edge that protects the base edge and provides extended service life. In addition, bucket surfaces subject to heavy wear, such as corners, are protected with replaceable, weld-in inserts of premium-grade steel (400 BHN).
