Load Sensing Hydraulics. The 966Hfeatures a load sensing hydraulic systemthat automatically adjusts to operatingconditions to provide only the hydraulicflow required by the implement forimproved fuel efficiency.With the new Priority ProportionalPressure Compensation Valve,implement control is improved over the previous system – raise/lower and rack back/dump can be operatedsimultaneously and fine modulation isrepeatable for improved productivity.Operators will notice enhanced ease ofoperation, more rimpull into the pileand a 20% increase in lift force.

Electrohydraulic Implement Controls.Finger Tip Electro hydraulic implementcontrols on the 966H provide theoperator with responsive, smooth andprecise control of bucket and lift arms.The implement control console alsofeatures a Forward/Neutral/Reverseswitch allowing easy and fast directionalchanges that helps reducing cycle times.

The standard programmable automatickick-outs provide flexibility andproductivity for precise load and dumptarget heights. Tilt, lift and return-to-digkickouts are set by positioning thebucket or work tool and setting a rockerswitch in the cab.

Constant Horsepower. On manycompetitive machines, gross horse-power is constant, meaning that netengine power available for actual work will vary based on demands made from parasitic sources, such as air conditioning or cooling fans.The Cat C11 engine is electronicallyconfigured to provide constant nethorsepower at full parasitic loadenhancing productivity and improvingfuel efficiency.

Separated Cooling System. Manycompetitive loaders use cooling systemsthat pull air in from the sides, throughthe engine compartment and exhaust itout the rear of the machine. The 966Hcooling system is isolated from theengine compartment by a non-metallicshield. The hydraulically driven,variable speed fan draws in clean airfrom the rear of the machine andexhausts it out the sides and top of thehood. The end results are optimalcooling efficiency, increased fuelefficiency, less radiator plugging andreduced operator sound levels.

Planetary Power Shift Transmission.Increases number of cycles per hour. The electronic planetary power shifttransmission with automatic shiftcapability is designed, developed and built by Caterpillar. The electronicallycontrolled power shift transmission allowsfull power, very responsive directionalchanges that have a direct impact onmachine cycle times and productivity. The operator can choose between manualor autoshift modes.
