CB 224 D Caterpillar CB 224 D Specifications & Technical Data (2000—2004)

Production-Sized Results in Small Packages

Maneuverability, transportability and versatility are combined in easy-to-operate machines that will help you meet and exceed your tons-per-day production needs.

Engine Features

Precise balance and optimum running speed for smooth operation and extended engine life. The engine is liquid-cooled, keeping temperature low and helping reduce component wear. The timing drive uses three helically cut gears that help reduce noise levels. Additionally, the heat-treated chrome molybdenum steel crankshaft provides a durable service life.

Engine

Caterpillar 3013 naturally aspirated, water-cooled, 4-stroke, 3-cylinder diesel engine. The following ratings apply at 2800 rpm when tested under the conditions for the specified standard: Net power advertised is the power available at the flywheel when the engine is equipped with fan, air cleaner, muffler, and alternator. Dual-element, dry-type air cleaner with visual restriction indicator.

Pod-Style Weight Housings

Pod-style weight housings are assembled and sealed at the factory to ensure cleanliness, extended bearing life and easy field exchange/service. Change interval for bearing lubrication is every three years or 3,000 hours. Balance between frequency and amplitude provides a good mat finish for commercial work.

Excellent Forward and Rearward Visibility

Excellent forward visibility allows the operator to see objects 0.58 m high and 1 m in front of the machine. Rearward visibility is even better, as the operator can see objects that are 0.35 m behind the machine and flush to the surface. The low-profile engine enclosure provides unobstructed sight lines to ground personnel working near the machine.

Water Spray System

Constant or intermittent spray capabilities provide extended operation between refills. Triple water filtration reduces machine downtime caused by system clogs. Extended-life water pump provides optimum spray and flow. Water pump and filters are conveniently located for easy access. Large water tank drain allows system to be drained in less than five minutes. Additionally, spray bars are constructed of stainless steel for corrosion resistance. The water tank is reinforced polyethylene. An electric water pump provides either continuous or intermittent spray, with the intermittent spray setting increasing spray time by 50 percent over the continuous setting. Triple filtration includes a filter on the tank fill spout, an in-line filter at the water pump, and filters on each spray nozzle. Furthermore, spray nozzles are easily removed without tools for cleaning.

Electrical System

The 12-volt electrical system includes one maintenance-free Cat battery and color-coded and numbered wiring wrapped in nylon braid. The system includes a 55-amp alternator. The starting system provides 750 cold cranking amps.

Tire Wetting System

Tire Wetting System allows a solvent to be sprayed on the tire surfaces, helping prevent asphalt from adhering to the tires. One spray nozzle is positioned above each tire, and the system is controlled with a momentary switch on the control console.

Drum Design Keeps Production High

Specially designed drum edges help eliminate marks on deep lifts or when turning. Drums are constructed of rolled steel plate and are finished to reduce surface irregularities. Replaceable rubber mounts isolate vibration and enhance vibratory capabilities. Each drum is fitted with two retractable, spring-loaded, self-adjusting scrapers, positioned at the front and rear of each drum. Ends of each drum are fitted with steel plates that help prevent rocks, soil, asphalt or other material from entering the ends of the drums.

Transmission

CB-214D and CB-224D – Variable-displacement piston pump supplies pressure flow to fixed-displacement hydraulic motors that drive the front and rear drums. CB-225D – Variable-displacement piston pump supplies pressure flow to a fixed-displacement hydraulic motor that drives the front drum, and the pump supplies pressure flow to two fixed-displacement motors that drive the rear wheels. A propel lever located at the operator’s station provides smooth hydrostatic control of the infinitely variable speeds in both forward and reverse.

Wheels and Tires

CB-225D – 9.5/65-15 6-ply tires are standard. Each tire is equipped with a replaceable scraper. The scrapers help clean asphalt or soil off the tires. The scrapers can be positioned above the tires when they are not needed. Wheels are on a fixed axle.

Operator Comfort

Single-lever control provides simplified operation, making the machines a perfect fit for inexperienced operators. Easy-to-understand instrument panel allows the operator to quickly verify the status of machine systems. Lockable cover protects instrumentation and gauges. Low sound levels make them comfortable for both operators and spectators. Operator’s station is isolated with four rubber mounts that help eliminate vibration before it reaches the operator, controls and instrumentation.

Instrumentation

The control console includes: steering wheel; water spray system switch; vibratory drum selector switch; horn; start switch; heat set switch; parking brake; and a four-segment light for hydraulic oil temperature, oil pressure, alternator, and engine coolant. The vibratory system is activated with a switch on the top of the propel lever. When the vibratory system is activated, a vibration indicator light illuminates. The engine throttle lever is located on the left side of the control console pedestal. If equipped with optional light packages, switches and a turn signal light are located on the control console. The machine is protected from vandalism with several covers, and the control console, hood, and compartment for the Operation and Maintenance Manual are equipped with lockable covers.

Sound Levels

Sound level measured at the operator ear (sound pressure) is 80 dB(A), and the average at spectator (sound pressure) measured at 7 m is 73 dB(A).

Brakes

Brake systems meet SAE J1472, ISO 3450 and EN500-4. A spring-applied, pressure-released brake inside each propel motor immobilizes the roller. Activation is by a switch on the operator’s console or when the engine is shut off.

Steering

An engine-driven gear-type pump supplies hydraulic fluid for the steering circuit. Hydraulic system: One 70 mm bore, double-acting cylinder powered by a gear-type pump. Output at 2.800 rpm is 23 liter/min with relief valve at 117 bar.

Frame

Frame is fabricated from heavy gauge steel plate and joined at the center articulation pivot. Two self-aligning bearings on the pivot housing provide a ±32 degrees steering angle, and a horizontal pin provides a ±10 degrees oscillation angle. The articulation pivot is structurally reinforced for extended service life. For transport purposes, the articulation pivot can be secured at the zero steering angle.
