Hey there! As a supplier of boom laser screeds, I've been getting a lot of questions lately about how the vibration system of these machines works. Well, you're in the right place because I'm gonna break it down for you in a way that's easy to understand.
The Basics of a Boom Laser Screed
First off, let's quickly go over what a boom laser screed is. It's a piece of equipment used mainly in the construction industry for leveling and finishing concrete surfaces. The boom part allows it to reach far and wide across a large area, while the laser system ensures a super accurate and level finish. And that's where the vibration system comes in. It plays a crucial role in getting that perfect concrete surface.
How the Vibration System Kicks In
The vibration system in a boom laser screed is all about making the concrete workable and getting rid of air bubbles. When fresh concrete is poured, it's full of air pockets. If these air pockets aren't removed, the final concrete surface will be weak and have a rough texture. That's where the vibration system steps in.
The vibration is typically generated by a motor. This motor is connected to a vibrating shaft or a series of vibrating elements. When the motor starts running, it creates a high - frequency vibration. This vibration is then transferred to the screed blade or the troweling surface that's in contact with the concrete.
Types of Vibration Systems
There are generally two main types of vibration systems used in boom laser screeds: external and internal.
External Vibration Systems
External vibration systems are usually attached to the outside of the screed. They're easy to install and maintain. The vibration from external units is transmitted to the concrete through the screed blade. This type of system is great for smaller to medium - sized jobs. For example, when you're working on a small commercial building floor or a driveway, an external vibration system can do the job just fine.
Internal Vibration Systems
Internal vibration systems, on the other hand, are built into the screed. They provide a more direct and powerful vibration to the concrete. This type of system is often used for large - scale projects, like industrial warehouses or big parking lots. The internal vibration can penetrate deeper into the concrete, ensuring that the air bubbles are removed from the entire depth of the pour.
The Role of Vibration in Concrete Compaction
The main goal of the vibration system is to compact the concrete. Compaction means squeezing out the air and making the concrete particles pack together tightly. When the concrete is properly compacted, it becomes stronger and more durable. It also has a smoother surface finish.
The vibration causes the concrete to flow more easily. The high - frequency shaking breaks the surface tension between the concrete particles, allowing them to move around and fill in the gaps. This is especially important around reinforcing bars and in corners where the concrete might be difficult to place without proper compaction.
Adjusting the Vibration
One of the great things about the vibration system in a boom laser screed is that it can be adjusted. Different concrete mixes and project requirements call for different levels of vibration. For example, if you're using a high - slump concrete mix (a mix that's more fluid), you might need less vibration compared to a low - slump mix (a stiffer mix).
Most boom laser screeds come with a control panel that allows the operator to adjust the frequency and amplitude of the vibration. Frequency refers to how many times the vibration occurs per second, while amplitude is the distance the vibrating element moves. By adjusting these settings, the operator can ensure optimal compaction for the specific job.
How Our Boom Laser Screeds Excel in Vibration
At our company, we offer some top - notch boom laser screeds with excellent vibration systems. For instance, the HWAON200 - 4Ltelescopic Arm Laser Leveling Machine has a powerful and adjustable vibration system. It can handle different types of concrete projects with ease. Whether you're working on a residential slab or a large sports complex, this machine's vibration system will ensure proper compaction and a great finish.
Another great product is the Boom Screed with Vibrating System. This machine is designed specifically for jobs that require a high level of precision in vibration. The vibrating system is integrated seamlessly with the boom and the laser leveling system, allowing for a smooth and efficient operation.
And then there's the 6M Driving 360 Degree Turning Telescopic Boom. This beast of a machine not only has a long - reaching boom but also a highly effective vibration system. You can easily maneuver it around the job site while getting the best possible compaction for your concrete.
Maintenance of the Vibration System
Just like any other part of the boom laser screed, the vibration system needs regular maintenance. This includes checking the motor for proper functioning, lubricating the moving parts, and making sure the vibrating elements are in good condition. If the vibration system isn't maintained properly, it can lead to uneven compaction and a poor - quality finish.
Why Choose Our Boom Laser Screeds
