Excavator Attachments and parts An excavator’s design allows the construction equipment to be used for multiple purposes. Hydraulic excavator capabilities have expanded far beyond excavation tasks with buckets. With the advent of hydraulic-powered attachments such as a breaker, a grapple or an auger, the excavator is frequently used in many applications other than excavation. Many excavators featu...
Excavators are a classic piece of construction equipment with an eye-catching silhouette. The boom rears above the other machines on the construction site, and the tracks are ridiculously filled with muck while the dump trucks wait in line like a pack of ants. Wherever it works, the excavator is the king of the job site. In this article, we’ll be discussing in-depth the different parts of the exca...
Track roller: The purpose of track roller is to transfer the weight of the train to the ground and roll on the tracks. In order to prevent derailment, track roller should also prevent the track from moving horizontally relative to it. Track roller often works in mud, water and sand, and bears strong impact, the working conditions are extremely bad, the rim is easy to wear. The requirements o...
Track guards guide the track links between the flanges of the bottom rollers. VemaTrack’s range includes track guards for the most common brands in the machine class of 10 to 35 tons. We make these custom to machine specifications, using high grade steel. Track guards ensure that the track link stays within the machine’s tolerances, in order to prevent damage to the rollers and the track link itse...
What is a slewing bearing? A slewing bearing or slewing ring (also called a turntable bearing) is a rotational rolling-element bearing that typically supports a heavy but slow-turning or slowly-oscillating loads in combination (axial, radial and moment loads), often a horizontal platform such as a conventional crane, a swing yarder. How does an excavator swing bearing work? In an excavator, a hori...
Link H Bucket Links are also known as H Links or H Brackets due to their shape. This is the main link that connects the lower boom ram to the bucket (or quick hitch). It is this main link that moves the bucket in and out as the hydraulic lower boom ram extended and contracts. What is the bucket linkage mechanism of an excavator? Excavator bucket linkage is the most important part in the mechanism ...
What is a travel motor? The travel motor is essentially the hydraulic motor interfaces with the final drive, providing the power that the final drive transforms into torque. That torque is transferred to the sprocket, which then turns the wheel and track. What is the function of a travel motor on excavator? Travel motors are hydraulic motors that increase driving power properly for the travel cond...
