What Is an Articulating Boom Lift?
The articulated boom lift is a heavy duty machine capable of performing a wide variety of tasks from construction applications to electrical repair. These highly maneuverable lifts make working at heights much safer and efficient.
Height
Articulating booms are also known as knuckle boom lifts. These equipment are capable of reaching heights from thirty six feet to one hundred thirty one feet, depending on the model of the specific lift.
Design
The articulating boom has a huge arm or boom with multiple bending elbows. These are in conjunction with extendable arms that allow the articulating lifts to reach outwards and over things as well as upwards.
Articulating vs. Telescoping
Telescoping or straight boom lifts have a working height that ranges from forty six to eighty six feet. Unlike articulating lifts, these ones do not have elbows and extend in a straight line. This simplifies some of the lift training but also restricts the areas which are able to be reached with it.
Advantages
The articulating boom lift design makes them the most able to negotiate around obstacles and objects. These lifts are convenient for indoor application, available in electrical models and have zero tail swing. These particular types of lifts are ideal for crowded work situations.
SJ 46AJ
Skyjack has built the A-Series Articulating Boom with many of their most dependable and efficient design features. The SJ 46AJ offers an industry leading, three hundred sixty degree continuous turret rotation which is standard equipped. Due to the turret design allowing for easy operation in tight spaces, this model provides zero tail swing as well.
Skyjack is known for providing extreme terrain ability and positive traction. These features are offered by the axle based 4WD, that is provided in many of Skyjack's product designs. These machines are known for having a dependable and rugged drive train and proven low maintenance. Furthermore, the AJ has been designed with a rear axle hydraulic differential unlock and lock switch. This enables the operator to lock the rear differential when traveling on rough terrain.
Other Types of Crawler-Mounted Cranes
Industrial wheel tractors in the 1920s, such as those built by Fordson and McCormick-Deering were rapidly adapted so as to be able to power a huge variety of equipment. Like for instance, half-swing cranes and shovels were manufactured by some companies around the tractor's power train and engine and the wheels became replaced by crawlers.
Crawler tractors came into widespread use during the 1930s. Immediately after, many manufacturers began making attachments for them, like for instance a range of lifting machine devices.
For example, side-mounted booms were mainly used for pipe-laying where it gained its nickname the "pipelayer." These types of machines are often utilized nowadays for attending to cleaning up railroad derailments. Because of their compact design, mobility and size, as well as outstanding lifting capacity, these kinds of machines are great for this use. What's more, swing booms which mounted on top of the engine compartment became available too.
LIke a crawler tractor, crawler cranes travel on crawler tracks. Because of their intense weight, these machinery do not move really fast. Usually, the crane is powered by one engine and may be controlled by 2 or more cable operated drums. The crawler cranes come outfitted with a lattice boom or a telescopic arm which is easy to extend by utilizing hydraulics. The lattice boom must be assembled manually by adding multiple sections.
Tower Cranes
Tower cranes are those found in big construction projects. These kinds of cranes are essential to be erected and broken down on location. They have to be transported by truck every time they are relocated. These tower cranes are exceptionally tall. They allow construction crews to transport heavy steel or concrete building parts to the tops of tall buildings. Tower cranes utilize a hydraulic system to push each new crane section up into place and therefore, are self-erecting.
