Caterpillar 336E Excavator

Right from building a house or a tall rise to constructing bridges, dams and roads, you need an excavator for every type of work. Excavators are the machines that dig the earth and get the mud out. It is needed for several purposes. Most importantly, it is needed to prepare a foundation for the building. So you dig up the ground to start setting pillars from there and in order to do this digging business, you need a good excavator. Excavators are of different sizes. You can get a smaller one for small excavation works or deploy a bigger one for huge construction or mining projects. The size of an excavator depends largely upon the kind of project you will need it for.

All the construction equipment manufacturing companies produce excavators with different unique features that hit the consumer market every year. However, the excavators produced by CAT are simply outstanding out of the league. Caterpillar’s 336E excavator is one such extraordinary piece of steel that does not have much competition from its rivals. Caterpillar has always maintained its performance and has ensured that the trust consumers have on the brand remains intact. It is because of this CAT products get overwhelmingly positive responses whenever it comes out with a new model. People are dead sure that it will have something new to offer them.

Speaking more about the 336E excavator, the machine has a net power of 266 hp. The figure only suggests how good the machine is in terms of power. It has a displacement of 537 cu in and the total operating weight of the machine is 30498 kg or about 68,000 lbs. The fuel capacity of the excavator is 620 liters with the cooling system fluid capacity and hydraulic system fluid capacity of 40 and 410 liters respectively. One of the most intrinsic features of the machine is its engine oil capacity which is 40 liters. Not many machines of this size has this capacity of engine oil installed in it. The hydraulic pump flow capacity is 280 liters per minute and the swing drive fluid capacity is 19 liters and the speed of the swing is around 10 rpm.

Changing our focus on the undercarriage, the shoe size is around 800 mm with maximum travel speed of 5km per hour and a drawbar pull of 300 KN. The minimum and the maximum capacity of the bucket is around 1.2 yd3 and 3.3 yd3 respectively. This model of excavator can be installed with 3 different boom/sticks. HEX1, HEX2 and HEX3. The maximum digging depth for all the 3 options are 27 ft. in, 24.6 ft. in and 21.8 ft. in respectively.

If you intend to buy this machine, you can get in touch with the nearest authorized Caterpillar dealer or heavy equipment dealer and he should be able to help you with the proceedings to buy this stuff. Caterpillar has managed to keep the price within the range so that people do not find it very hard to buy it. One can even visit Caterpillar’s website and can order it online.


Tips on how to run an excavator

We basically believe that working on a heavy equipment is as simple as driving a vehicle. It may have the same feature as what we see in a car but the ones who actually operate heavy equipment beg to differ. One can simply not compare working on heavy equipment with driving one’s car as the former is lot more complex in nature and the person working on the machine has to be extra careful while he is on it. He got to check a lot of things before he begins with his work and needs to be sure that all the things that he needs during his work are working just fine. In case he notices any issue, he should be reporting it to the supervisor in charge or should take things in his control and ensure that the machine is in order before he kick starts with the job.

Not all the heavy equipment are tricky to work on but there are machines like excavators that can really takes its toll on the operator. Especially if the operator has to function in an extremely rough and rigid terrain, things may become all the more strenuous for him. Only with the help of experience will one be able to manage the machine smoothly or else things may go out of his control and the consequences can be intensely severe.

We would be discussing few important tips that one should be following while they work on an excavator.

Proper usage of the joystick:-

One needs to understand that the joystick in an excavator is the brain of the machine and the way you use the joystick, the machine will flow accordingly. The joystick is used extensively to keep a control on the movement of the cabin and the bucket attached to the machine. So if you are moving the joystick correctly, the excavator will move the way you want it to. By using the one to your right, you will control the scooping that will help the boom to move in the upwards and downwards position. The joystick to the left of the driver controls the cab. So if you use the one to your left correctly, it will move the machine to the place you want it to go. It also helps in enlarging and shortening the length of the boom.

Drive rods are equally important:-

If you want to increase or decrease the speed of the excavator, you can do it with the help of the drive rods that lies between the legs of the operator. Each rod has its own exclusive purpose. It works co-related with the tread and when pushed forward or backward will move the tread of that side. If you want to drive the excavator straight then you simply have to push both the sticks at the same time in the forward direction and it will speed up and if you pull them back will drive the machine backwards.

Alongside with lot of experience in operating an excavator, following these simple tips can be really useful to operate the machine.

Excavators And Their Usages-An Outline

The excavators are the engineering and the construction vehicles, which have a really unique look with a cab mounted on the pivot arm, a long arm and an undercarriage that includes wheels or the tracks. These machines have the customized buckets to fit with the required job as there are various types of buckets available for the usage in the construction. Often the look of these heavy vehicles can be customized perfectly with the capability of changing the buckets or the thumbs.

These heavy vehicles are generally specified or defined by the arm power, the digging depth and the dump height power rating. But these days, these excavators also come with various types of attachments like as the breakers, augers and the grapples. Besides, the buckets also come in various types, for example the rock, sorting, and the general purpose buckets.

The excavators either can be mounted on the tracks or the wheels. These are mainly used to help these heavy vehicles for the mobility and therefore these are used in various types of environments. The track hoes are one kind of excavators, which are basically mounted on the tracks.


Now let’s have a look at the different roles played by these excavators.


These heavy vehicles are mainly used for different types of roles like as the purpose of digging the holes, foundations or trenches. Besides, these are also used for some other purposes like lifting and placing the heavy materials like the pipes, demolishing, river dredging, mining and landscaping. These are also used for the purpose of brush cutting aided with the hydraulic attachments. The multipurpose roles of these excavators allow these to be used in different types of locations. Other important roles played by these heavy vehicles are handling different types of materials effectively.

The excavators come in various sizes and types on the basis of the different types of jobs these play. The small excavators are generally called compact or mini excavators and these mainly come equipped with the bulldozer blades at their front part. These are capable of fitting through the doorways. On the contrary, the large ones are capable of weighing around 180000 lbs.

The compact excavators are mainly found in two different types known as the zero tail swing and the tail swing models. Usually, all the compact models used to come with the tail swing models and these also had a rear counterweight attached to these in order to prevent the chances of tipping during the digging process. But the counterweights make these really hard to maneuver these vehicles as these extend beyond the tracks. On the other hand, the zero tail swing machines have counter weights, which don’t extend over the rails and therefore these make it really easy for the operators to maneuver the jobs.

These days, it is also possible to take these heavy vehicles for rent from the renters as per your business requirements. This way you can get all the facilities that these excavators offer without the requirement of paying too high.
