Volvo Excavator Parts_ All You Need to Know

1. Volvo Excavator Parts: All You Need to Know In this article we cover Volvo excavator parts, where each fit onto the excavator machine, and how Volvo’s are different. It’s important to have an overview of the major components of excavators, so that if you are faced with Volvo excavator spare parts you can determine where they fit into the machine and what their function is. This is important because if you are comparing Volvo machinery parts to non-genuine machinery parts, then you will be able to determine just how important it is to get the highest quality, OEM parts. The Three Main Divisions of An Excavator But first, what are the major components of an excavator? For those who are unfamiliar with the machines (or for those who are familiar but would like a refresher on the terminology), this section details the major components of an excavator, touching on the important parts within

2. each. It’s important to note that this article focuses on large, tracked excavators which are the most common variety on worksites across the world (as opposed to their wheeled counterparts). Excavators can be divided into three major sections: the arm/boom, the cab, and the undercarriage. The cab section is broader than just the cab itself (where the operator sits) and includes the body of the excavator as well, which contains the engine. Plus, as you can imagine, the arm/boom section connects to the cab section, and the cab section connects to the undercarriage. The cab section connects to the undercarriage with a slewing ring, which is touched on in the undercarriage section. Arm/Boom Section The arm/boom section includes the arm, the boom, the bucket and its links, the cylinders, and any additional attachments that can sometimes be used on excavators. The boom refers to the length of metal that connects to the cab section and is hooked rather than straight. The arm is the length of metal which connects from the end of the boom to the bucket. The arm is sometimes also called the dipper or the stick. It’s important to get the terminology correct in this section because it’s common for people to call these components “boom arms” or use the terms interchangeably, which can lead to confusions between the Volvo machinery parts. This can be a real problem if you are looking for spare or replacement parts for the “boom arm” and end up not knowing which is the correct part you’re after. The bucket is at the end of the arm and is what you’d expect. It has teeth which are used to dig into the material, such as earth, which is being excavated. The general term for these attachments such as the bucket teeth which dig into the material are known as ground engaging tools. These will wear away over time and are designed to be replaced, which is cheaper and easier than replacing the whole bucket. They are there to protect the bucket. The hydraulic cylinders on the arm/boom section are what enable the manipulation and movement of the arm by the operator. There are three: one each for the bucket, the arm, and the boom. Each connects to the section ‘behind’ it, enabling the one in front to tilt (with the boom cylinder being attached to the cab section). The bucket cylinder attaches to a h-link and a side link (also called a tipping link or, sometimes, a banana link and even the dog bone). These links function as levers and improve the bucket tipping ability. The h-link connects from the cylinder to the bucket and the side link connects the cylinder to the arm. The last item in this section are the attachments that can be used with excavators, such as brush cutters, rakes, and more. The Excavator Body This section includes the cab where the operator sits, as well as the rest of the body of the excavator. In this section of the body is in the engine, fuel tank, the hydraulic fluid tanks, and the

3. counterweight. The cab itself includes the roll over protection system and the main controls for the excavator. The engine is connected to the hydraulic system through the main control valve, with the hydraulic pump managing the pressures in the cylinders as the operator manipulates the arm/boom section. Other than this, the other components of this section are fairly self-explanatory. Some details to be aware of include knowing that larger excavators will be powered by diesel fuel because using diesel engines is generally more efficient. When it comes to the Volvo excavator spare parts of the excavator body, there are a lot of items, ranging from the hydraulic fluid, to engine components, cab components such as the chair, seatbelt and controls, as well as an array of filters. This includes air filters for the cab, fuel filters for the engine, filters for the hydraulic fluid, and so on. Volvo prides itself on the quality and durability of all their OEM parts, all the way down to these filters. Undercarriage The undercarriage of the excavator relates to all of the components of the tracks. These include the track frame, the track itself (pads, shoes, chains, and bolts), the sprocket and idler, and the rollers. The track frame functions much like the axle does on wheels, connecting the tracks to the cab section. This section is connected to the cab through a slewing ring, which is a large bearing and a connected motor which can rotate the cab relative to the undercarriage, allowing the bucket to move laterally, as well as vertically and towards and away from the cab. The rollers are used to align the tracks as they rotate around the frame and the idlers, which are the large, barrel-shaped wheels right at the front of the tracks, are also used to guide the tracks. The sprocket is where the force is applied to the tracks themselves, allowing the excavator to traverse the worksite. The track itself is made up of pads and the shoes, which dig into the ground, the bolts, which join the pads together, and the chains, which is what the tracks are attached to and which the sprocket engages with to pull the tracks along.
