1. The bulldozer track roller is the excavator chassis accessories mainly have four wheels: four wheels refer to the track roller, carrier roller, front idler, sprocket; A belt is a track. The track roller plays a supporting role and is located between the lower surface of the left/right beam of the bottom frame and the track, depending on the tonnage of the excavator. Usually there are 5-10 on on...
What are the parts of a bulldozer undercarriage? A tracked bulldozer’s undercarriage allows the machine to move forwards and backwards simply and efficiently and that movement takes a number of different parts working together to happen. Some of the most important parts in the dozer undercarriage are: 1.Track chain In construction equipment, tracks can either be metal or rubber. Metal tracks are c...
How to maintain undercarriage of bulldozers and excavators? Undercarriage parts have a huge effect on working performance and walking performance of bulldozer and excavator. Maintenance is a key for walking-speed of bulldozers and excavators. There are some tips for maintaining undercarriage parts for bulldozers and excavators as follows: Front Idler is in the front of the track frame. The functio...
If you’re familiar with construction site operations, you’ve probably heard of the terms “bulldozer” and “excavator.” But have you ever stopped to think about what the differences are? Fortunately, we provide you with excavator and bulldozer tips. So, keep reading and let’s go beyond theory and get into the nitty-gritty of excavator vs bulldozer. What is Excavator An excavator is a construction ve...
Like any component of a machine that is subject to constant impacts, high friction from rotating parts, and heavy loads, the undercarriage on a bulldozer requires consistent monitoring and regular maintenance. In fact, maintenance to a dozer’s undercarriage is consistently one of the highest costs associated with the machine’s maintenance and operating costs. A few common issues in a dozer’s under...
Know The Excavator Inside and Out Every excavator operator knows behind their seat is an operator’s manual that is full of helpful and insightful information from maintenance schedules to the locations of grease zerks to basic tips for better operation. Your operator’s manual is the first source of wisdom for a smart maintenance plan, but knowing your machine is often about more than what’s in the...
An excavator arm consists primarily of a boom, stick, and attachments. Hydraulic cylinders power the movements of the parts, pins bind parts together, and linkage attaches parts to one another in ways that allow for parts to pivot to perform actions. While not part of the arm, the entire hydraulic system is controlled by the main hydraulic pump and main hydraulic valve, located in the house of the...
Maintain a Clean Final Drive and Undercarriage At its most basic, keeping your final drive and your undercarriage clean is about keeping your final drive in view since leaks and other issues can hide behind layers of dirt and grease. Routinely taking time to blast off dirt and debris is the best way to unmask troubles and make sure if they do show up, you’ll spot them right away. Cleanliness...
Starting the machine 1.Determine if the machine is in an ISO or SAE control pattern These are the two standard control patterns for excavators. The difference between the two is that in ISO, the left hand controls the swing and boom and the right hand controls the stick and bucket motions. SAE reverses this pattern, so if you’ve been trained on one, switching to the other is difficult. Most newer ...
Regular hydraulic cylinder maintenance is critical to system maintenance and performance Here, we share top tips for successful hydraulic cylinder maintenance. 1. First things first - keep hydraulic fluid clean Many hydraulic failures occur due to hydraulic oil contamination. This is important to prevent damage to the system and components. If the hydraulic fluid is contaminated, it must be cleane...
Four key factors when choosing the right excavator teeth 1. Manufacture The construction and material of the excavator teeth and adaptor is a major criteria, as this will directly determine its wear life and strength, but so is the shape and design. Teeth are cast in foundries, mostly in third world countries these days, for both cost and pollution reasons. The materials used in the casting proces...
Measure the horizontal distance from the inside side of one of the bucket's side plates to the inside side of the other side plate. Measure the inside depth of the bucket by measuring from the deepest point in the bucket to a point along the center of the outside edge. What Measurements Do I Need to Search For an Excavator Bucket? To get the dimensions you will need to assist in your search for a ...
