Excavators

One of Capital Area Mopars favourite vehicles for building and construction aid is the excavator. Many may not realise what an excavator is despite the name of the machine, but it is simply the heavy construction equipment that consists of a boom, stick, bucket and cab for the operator in a rotating platform that is the house. Some have often called them power shovels incorrectly, but they are the more mechanized and high-powered version of the steam shovel, requiring hydraulic fluid to operate. At times, excavators have been named by several difference names such as JCB’s, Diggers, 360 excavators and even mechanical shovels. In the UK, we actually call them by the name “Rubber Ducks”.

If you are on a building or construction site there may be a number of reasons you will have to use an excavator during your project. Excavators can be used for both forestry mulching and work, for brush cutting, handling of heavy materials as the bulldozer does, digging of foundations, holes and trenches for the construction site, construction in a general term and even river dredging. Other uses for it have been for general grading and easier landscaping, mining and even as a snow shovel or snow blower during harsh winter conditions.

 

Configurations

 

Where excavators become really interesting and also really useful is with the varying amount of sizes and uses that come with it. The Caterpillar is one of the smaller designed excavators that are regularly used, and it weighs 930kg. Yet the same company creates the largest excavator in the world, which not only weights almost 1 million kilos, but has 4500hp. The actual intensity and design the excavator is insane, and almost incomprehensible if it wasn’t for the fact it has already been completed. The engines themselves drive hydraulic pumps, and the average excavator will have three of these at a time. The two main pumps are actually used to supply oil for the majority of the excavator’s functions, while the third is mainly used to pump into pilot control. Some believe that all three pumps can’t be used at the same time but this is actually a myth since most of the excavator’s functions actually require all three pumps to be used simultaneously.

The excavator itself is attached to both an undercarriage and appendices known as the house. The undercarriage is what is able to hold the blade, tracks, the track frame and the drives, while the house is what holds the operator cab, engine, hydraulic oil tanks, fuel and counter weight for the excavator. Finally, apart from these the excavator also holds the dipper arm, which is the stick that is used to dig through the ground itself. Since the bucket needs a strong pressure, the stick is able to provide that for the excavator which ensures both safety for all at the worksite, but also efficiency.
