I have never operated a d9 size machine, so was wondering about them in production rates. I can see the rates for d10 and d11 the machine operating weights really jump up. I can only compare an 8n to a 9n and yes the 9n will rip more and push a healthy pile of dirt. I ran them in hard rock and needed the weight the 9 provided. DesertwheelerDec 16, I dunno, but I wouldn't question the rates as published by Cat.

Undoubtedly they were established using the correct and established production techniques in probably ideal conditions.

There is only one way to push dirt to reach maximum production and, in the real world, a good operator on a smaller tractor can easily out produce a wannabe on a larger rig.

The D9 dozer became what one thought of when thinking of huge pieces of heavy equipment and for good reason. In Caterpillar introduced 10 models for testing that were to become the new D9 machine, they were modeled D9X x for experimental.

The following year the hp D9 dozer came on the market powered by Cat's D engine which stayed in the machine until when Cat upgraded the D9 to the D9L, although in the engine was remanufactured to produce hp. The D9 offered little in the way of operator comfort, it was just one huge piece of moving metal that moved huge amounts of material and destroyed anything and everything in it's path. When it got really cold, they would turn the fan around so the hot air from the engine being cooled would blow back into the cab area.

This was all right, but there was no climate control, it was either full on or nothing. If the operator got too warm, he had the only other option of shedding clothes. Today's D9 dozers with cabs give full climate control along with a much more comfortable seat, the cab reduces noises to a considerable degree and there's even a radio and CD player.

A early D9's Cab When Caterpillar introduced the elevated drive sprocket on it's D10 bulldozer, the D9L was the first of the 9 series to follow suit. It was later added to the D8 and D7 series of dozers. You can read more about the elevated sprocket design on our page about the Caterpillar D They use a cross flow cylinder head to increase air into the combustion chamber, water cooled turbochargers, mechanical - electronic controlled injection system which delivers micro blasts of fuel just prior to and just after the main injection and a computer controlled fuel injection process.

There are 3 different blades available for the D9: 1. A straight blade which is used for grading. A universal blade which is taller and curved along with side wings to push bulk material. A combination blade which is shorter, less curved and smaller side wings. It is attached to the rear of the machine and used for tearing up hard and frozen surface areas. The second option for a rear attachment was a winch.

The D9 machines were mainly used for strip mining removing overburden, clearing right of ways, and road construction. It became apparent that Caterpillar needed a larger machine to replace the D9. Other manufacturers already had larger machines on the market and market economics looked good. In March Caterpillar sent 10 machines out to different jobs performing different kinds of work. A group of construction workers build an airstrip on a South Pacific Island where their D9 dozer hits a meteorite that has a strange alien life force in it.

The life force is transferred to the D9 and the D9 takes on a life of it's own, attempting to kill all the workers on the island. Find out more about the movie Killdozer here. The Israeli Army purchased D9's in the 's and added armor plating along with machine guns and grenade launchers turning the D9 into a tank of sorts, complete with manned crew.

Israel uses the Armored D9 to raze Palestinian houses, intimidate their foes and uproot precious trees and destroy landmarks and agricultural areas. The United States armed forces has used D9 bulldozers for clearing land during the Vietnam War and in the war in Iraq.

These machines were not modified to any degree to make them into tanks, but were basically as was from factory, only with different paint schemes than the traditional Cat Yellow. The Army has bought several "armored kits" from the Israeli's and used them to modify several D9's, but have not used them as weapons on a battlefield.

Caterpillar D9 Dozer History. Search This Site. Home Page Site Map.The role of a crawler dozer or a crawler tractor is quite interesting in the mining and construction industry.

This equipment is needed more at those sites where there is an existing house or building structure that needs to be demolished. For that reason, you need a huge dozer equipment to maul that down and a construction equipment company that has been manufacturing high-quality dozers for years is none other than Caterpillar Company, who is continuously producing big heavy dozer machines. Caterpillar is one such popular company that has pioneered in making giant bulldozers and is known for making work-efficient and reliable machines.

The company is not just known for work-efficient dozer machines but is also renowned for producing other forms of heavy construction equipment that are needed in day to day construction activities. In other words, we can say that the company is specialized in manufacturing high-quality dozers. The Caterpillar Company has been introduced Cat D9H dozer which has achieved praises from millions of people from all over the globe.

It keeps material moving with the reliability and low operating costs you expect from Cat dozers. Greater efficiency and versatility--ideal for construction, aggregates, waste, forestry and mining.

The C engine is a field proven engine that delivers excellent reliability and durability in all applications. The 18 liter engine delivers a high torque rise, providing excellent lugging capacity to move heavier loads more efficiently.

The mechanically controlled engine provides easy maintenance and repair in remote areas where diagnostic tools may not be available. The C block is cast from high-tensile-strength gray iron. The one piece casting is stabilized to maintain internal dimensions under all operating conditions. The engine uses two intake and two exhaust valves with hardened valve faces that are designed to be reground. Rotators turn the valves about three degrees each lift to distribute wear and maintain heat transfer.

Valve stems are made from hardened, chrome plated steel to provide excellent wear and heat resistance. An internal top-deck cooling shelf increases coolant flow to the top of the cylinders for long cylinder liner and piston life.

The deep-skirted lower structure and heavy internal ribbing add strength and rigidity to the block. The crankshaft is a carbon steel forging, fully heat-treated, super-finished and dynamically balanced. Circulates coolant from the sectioned bottom tank up through one side of the cooling element and down through the other side returning it to the bottom tank. The cooling elements are individual core modules that are connected to a sectioned bottom tank.

There is no top tank to remove. With standard 9 steel fins per inch, a lower fin density reduces plugging. Brass tube construction within each core for improved reliability. Servicing can be performed without tilting the radiator guard. Each core module can be replaced individually without removing the entire radiatorsaving considerable cost and repair time. To reduce the potential for coolant leaks, brass tubes are welded to a large, thick header, improving strength of the tube-to-header joint.

In conditions with airborne abrasive materials an optional coated blower fan and sand blast grid should be used to minimize radiator damage. The proven Cat planetary power shift transmission operates with three speeds forward and three speeds reverse. With this design, many gears share the load as it gets transferred to the axles.

In contrast, with a countershaft transmission, just one gear carries the load. Helical and spiral bevel transfer gears reduce operator and spectator sound levels by design as well as location, being placed in the rear case of the machine.

The transmission features large oil-cooled clutch packs that efficiently absorb the energy of directional shifts for smooth machine performance and excellent operator comfort.

Proprietary F37 clutch material extends clutch life, especially in applications where extensive maneuvering is used to maintain peak machine productivity. This material also minimizes transmission oil contamination compared to materials used in other manufacturers' transmissions.Discussion in ' Dozers ' started by casecxOct 21, Log in or Sign up.

I am in need of specs for a cat D9G, for a walkaround video I am trying to make. Having a hard time finding them online, Help would be appreciated, thanks. Joined: Jan 16, Messages: 1, Location: In a van, down by the river. What kind of specs are you after? Lee-onlineOct 21, Just looking for the basics weight, HP, Blade Capacity, stuff along those lines.

Weight is dependent on the tractor setup, whether it's just the bare tractor, or if it has a blade and ripper, or just blade - and whether it has a cab, and whether the cab is open or fully enclosed.

The bare tractor upon its release in was 64, lbs. However, it gained weight as the years went by, and engineering improvements were made.

Then Cat started changing how the weight was measured, and moved to "operating weight". Other factors affecting weight are accessories fitted such as guards, tree canopies, whether heavy duty "extreme service" pads are fitted, condition of undercarriage, type of blade Angle, Straight or Semi-U. We always worked on the average late model D9G, commonly equipped locally with enclosed ROPS, straight blade, 3 valve hydraulics, and 3 shank ripper, as weighing over 50 tonnes ,lbs.

The Cat D9T has a reputation for outstanding productivity, operator comfort, and robust reliability. It is a highly versatile machine flexible enough to be used in heavy construction, quarries, landfills, forestry, and mine sites. Cat customers can count on the D9T's continued legacy of superior performance, long life, ease of operation and world-class service from the global Cat dealer network to be the backbone of their operation.

Meeting regulations is very important for your business. The D9T is powered by the Cat C18 engine — which meet today's most stringent emissions standards and are poised to take on tomorrow's challenges as well. Power through tough materials with full rated net power of horsepower at 1, rpm. You can't afford to have operators not dozing. Helping you get more done with maximum availability, the D9T's durable design makes repair and maintenance easy.

You can rebuild these dozers several times using the same frame with only minor repairs. It's not unusual for a Cat dozer to log more thanhours.

The backbone of the dozer is a heavy, strong and durable frame with high-strength steel castings and continuously rolled top and bottom frame rails. The D9T frame provides durable support to the undercarriage, elevated final drives and other components. Mechanical availability is one of your top concerns.

The D9T reduces downtime by making our machines easy to repair and maintain. Major components are modular in design, so most can be removed and reinstalled without disturbing other systems — which allows the D9T back on the job faster. You consider the safety of your workers a top priority, and we're doing our best to help you meet your safety goals.

Caterpillar considers the safety of everyone in, on or around Cat equipment when developing new products or enhancing safety features for existing products. Every day you are focused on productivity and cost per unit for increased profitability.

With the D9T fully suspended undercarriage you will get more cycles per day. Every additional cycle you get because of the smooth ride means increased production and lower cost per unit of material moved. The elevated sprocket and suspended undercarriage work together, increasing traction and giving the operator a smoother ride. The elevated sprocket design transfers implement shock loads to the mainframe, so final drives, axles and steering components are isolated from harsh impacts.

These benefits translate into higher production and longer component life.The Caterpillar D9 is a large track-type tractor designed and manufactured by Caterpillar Inc. It is usually sold as a bulldozer equipped with a detachable large blade and a rear ripper attachment. The size, durability, reliability, and low operating costs have made the D9 one of the most popular large track-type tractors in the world. The D9 is a series of heavy tracked-type tractors, carried on continuous tracks and usually used as bulldozers.

The series began in with a prototype tractor called the D9X. Ten D9X prototype models were built in The D9 came equipped with a 1, cid D which powered the D9 right up until the introduction of the D9L. Over its year life the D9G became the main crawler on many job sites, testifying to its sturdiness and design.

InWest Coast businessman Buster Peterson hooked up a pair of D9Gs to pushload the largest wheel tractor scrapers built. The D9H is still the most powerful conventional track-type tractor in company history.

The unit featured the same new type of elevated drive sprocket undercarriage as had been introduced on the larger D10 in The elevated-drive-sprocket undercarriage is a modular design. To repair the machines one breaks down the tracks and pulls the drive sprockets out.

As a result, one can pull the powershift transmission out the rear. InCaterpillar produced their 25,th elevated-drive-sprocket track-type tractor, a D9N. The L, N, R and T models of the D9 are visually very similar, differing primarily in the design of their internal systems. The D9R has clutch and brake steering, while the D9T has differential steering.

The D9's primary working tools are the blade, affixed to the front and controlled by four hydraulic cylinders, and an optional ripperwhich can be attached to the back.

The blade is mainly intended for earthmoving and bulk material handling: pushing up sand, dirt, and rubble. It also can be used to push other heavy equipment such as earthmoving scraper pans, and in military applications, main battle tanks. The dozer blade usually comes in three variants:. Like many other bulldozers, the D9 can be fitted with other devices such as mine plows. The rear ripper is intended for use in loosening rocky ground and ripping out larger stones.

It can also break frozen ground and excavate small ditches. The ripper can be replaced with a multi-shank ripper, allowing the bulldozer to comb the ground. The size, power and weight of the larger track-type tractors dictate that they are used primarily for major projects. The D9 is most commonly found in use in construction, forestry, mining, waste, and quarry operations.

Caterpillar Inc. D7G bulldozers are still very common in US combat engineering battalions, but there is a series of oft-recurrent suggestions to replace the lighter D7Gs with the newer and more heavily armored D9s. The Caterpillar D9 have been used by the Israel Defense Forces since it was introduced but an armored model, with Israeli developed vehicle armor kit, was introduced only inon the D9L.
