K Series Motor Graders Caterpillar 160K
Balanced Flow, Independent Oil Supply
Hydraulic flow is proportioned to ensure all implements operate simultaneously. Independent oil supply prevents cross-contamination and provides proper oil cooling, which means less heat build-up and extended component life.
Implement Control Valves
Provide outstanding operator "feel" and predictable system response for unmatched implement control. To help maintain exact blade settings, lock valves are built into all control valves. Line relief valves are also incorporated into selected control valves to protect the cylinders from over-pressurization.
Load-Sensing Hydraulics (PPPC)
A load sensing variable displacement pump and the advanced Proportional Priority Pressure-Compensating (PPPC, or "triple-P C") hydraulic valves provide superior implement control and better machine performance. PPPC valves have different flow rates for the head and rod ends of the cylinder. Continuously matching hydraulic flow and pressure to power demands creates less heat and reduces power consumption.
Consistent and Predictable Movement
The hydraulic system uses valves that provide PPPC control for precise implement and machine operation. These valves contain spools that are specifically cut for each hydraulic function on the motor grader. They compensate for differences in flow requirements, based on cylinder size and the difference in surface volume between the rod end (blue) and barrel end (red) of the cylinder. The result is predictable, consistent hydraulic speeds whether extending or retracting the cylinder.
ROPS/FOPS Cab offers Low Sound and Vibration Levels
The operator sound pressure level for the cab offered by Caterpillar, when properly installed, maintained and tested with the doors closed, meets or exceeds requirements set forth in ISO 6394:1998. The quiet environment improves operator working conditions. Steel non-skid steps use raised perforations to provide sturdy access to the tandems.
Brake Systems and Machine Protection
Brakes located at each tandem wheel offer the largest total brake surface area in the industry, delivering dependable stopping power and longer brake life. Standard circle drive slip clutch protects the drawbar, circle and moldboard from shock loads when the blade encounters an immovable object. Blade lift accumulators help absorb impact loads to the moldboard by allowing vertical blade travel.
Electrical Disconnect Switch and Engine Shutoff Switch
Disconnect switch provides ground-level lockout of the electrical system to prevent inadvertent machine starts. Engine shutoff allows anyone nearby to shut the machine down in case of an emergency.
Additional Safety Features
Laminated glass on the front windows and lockable doors to reduce theft and vandalism are available with the optional cab. Brake lights, conveniently located grab rails, back up lights and alarm help ensure a safe work environment.
Grouped Service Points on the left side to help ensure proper maintenance
Easy access to service areas speeds up maintenance and ensures that routine service is performed on time. Ecology drains shorten service times and help prevent spills. Radiator cleanout access gives the operator the ability to clear away debris and other materials that build up around the radiator. Fuel water separator is easily accessible from the ground.
Extended Service Intervals Reduce Downtime, Operating Cost
500 hour engine oil changes 4000 hour hydraulic oil changes 12000 hour engine coolant changes
Diagnostics and Machine Monitoring via Electronic Technician
The dash cluster panel provides enhanced machine information and diagnostic capability, which allows faster servicing of the transmission and engine. Cat ET is a two-way communication tool that gives service technicians easy access to stored diagnostic data and lets them configure the machine parameters through the Cat Data Link.
O-Ring Face Seals
O-Ring face seals create a reliable connection and are used in all hydraulic circuits to minimize the possibility of oil leaks.
Separate Wiring Harnesses
This modular harness design provides simple disconnects for major machine repairs or rebuilds.
Power Shift Transmission
Provides on-the-go, full-power shifting and inching capability. Direct drive delivers superior fuel efficiency and better "feel" of blade loads, material hardness and ground speed.
Optional Autoshift - Automatic Gear Shifts
This feature automatically shifts the transmission at optimal points (in gears 3-8) so the operator can focus on the work, improving safety, productivity and ease of operation.
Oil Disk Brakes - Completely Sealed, Adjustment Free
Oil-bathed, air actuated and spring-released, located at each tandem wheel to eliminate braking loads on the power train and to reduce servicing time. The large brake surface area provides dependable braking capability and extended life before rebuild.
Front Axle with Cat Live Spindle Design
Caterpillar® sealed spindle keeps the bearings free from contaminants and lubricated in a lightweight oil to reduce owning and operating costs. Two tapered roller bearings support the wheel spindle. The larger tapered roller bearing is outboard where the load is greater, extending bearing life.
Frame Structure - Provides Consistency and Strength
Front frame is a continuous top and bottom plate construction. Flanged box section design removes welds from high stress areas, improving reliability. The rear frame structure has two box section channels with fully welded differential case for a solid working platform. An integrated bumper ties the rear frame together into a cohesive unit, to handle high stress loads.
Drawbar, Circle and Moldboard (DCM)
The Y-frame drawbar is constructed of two solid beams for strength, durability, and precise blading control. This design allows the addition of a mid-mount scarifier without compromising blade positioning in extreme reach positions.One-piece forged circle stands up to high stress loads. Raised wear surfaces prevent circle teeth wear against the drawbar. The 64 uniformly spaced circle teeth are flame cut and heat induction hardened to resist wear, and the circle is secured to the drawbar by six support shoes for maximum support.The moldboard provides optimal curvature and large throat clearance that helps move all soil types quickly and efficiently. These features deliver excellent load distribution and minimal material buildup in the circle area while allowing large blade loads to roll freely.
Blade Lift Accumulators
This optional feature uses accumulators to help absorb impact loads to the moldboard by allowing vertical blade travel. Blade lift accumulators reduce unnecessary wear and help to avoid unintended machine movement for increased operator safety.
Designed to keep operators comfortable, relaxed and productive throughout the long work shift.
The 160K features: Electronic Clutch Pressure Control (ECPC) optimizes inching modulation and smoothes shifting Low efforts on all pedals, hydraulic controls and the transmission shifter Rocker switches and transmission shifter are backlit for night time operation The operator can adjust implement controls and steering wheel angle independently Clear view to the moldboard heel and tandem tires Fresh air filters above each cab door for quick replacement
In-dash Instrument Cluster
The instrument panel, with easy-to read, high-visibility gauges and warning lamps, keeps the operator aware of critical system information. The dash cluster panel provides enhanced machine information and diagnostic capability. It includes an engine coolant temperature gauge, an articulation gauge, voltage gauge, and fuel level gauge. Service brake air pressure gauges are also standard. Speedometer and tachometer are optional. All major systems are monitored by warning lights.
