What Is an Articulating Boom Lift?
The articulated boom lift is a heavy duty machinery capable of performing a wide variety of tasks from construction applications to electrical repair. These highly maneuverable lifts make working at heights a lot safer and efficient.
Height
Articulating booms are also called knuckle boom lifts. These equipment could reach heights from 36 feet to 131 feet, depending on the model of the particular lift.
Design
Articulating boom lifts are designed with many bending elbows. These are in conjunction with extendable arms which enable the articulating lifts to reach outwards and over things as well as upwards.
Articulating vs. Telescoping
Both straight or telescoping boom lifts could work at heights from 46 to 86 feet. Not like 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 could be reached with it.
Advantages
The design of the articulating boom lift helps to ensure it could negotiate around objects and obstacles. These lifts are convenient for indoor application, available in electrical models and have zero tail swing. These specific types of lifts are perfect for crowded work situations.
SJ 46AJ
The A-Series Articulating Boom engineered by Skyjack was designed for utilizing many of their dependable and effective design features. The SJ 46AJ offers an industry leading, 360 degree continuous turret rotation which is standard equipped. Thanks to the turret design allowing for easy operation in tight areas, this specific model provides zero tail swing too.
Skyjack is recognized for providing extreme terrain ability and positive traction. These features are provided by the axle based 4WD, that is provided in many of Skyjack's product designs. These machinery are known for having a rugged and dependable 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 ground.
Various Types of Crawler-Mounted Cranes
In order to be able to power a large variety of equipment, industrial wheel tractors were adapted during the 1920s, by Fordson and McCormick-Deering. For example, half-swing shovels and cranes were made by some companies around the power train and engine of the tractor and the wheels became replaced by crawlers.
In the 1930s, crawler tractors came into widespread use. Soon after, many manufacturers started making attachments for them, such as various lifting equipment devices.
Side-mounted booms for instance, were used primarily for pipe-laying at first and the machinery got the nickname "pipelayer." These machinery are often utilized today for attending to cleaning up railroad derailments. Due to their size, compact design and mobility, as well as excellent lifting capacity, these equipments are great for this application. As well, swing booms which mounted on top of the engine compartment also became available.
Similar to a crawler tractor, crawler cranes travel on crawler tracks. Because of their intense weight, these equipments do not move really fast. Usually, the crane is powered by one engine and could be controlled by 2 or more cable operated drums. The crawler cranes come equipped with a lattice boom or a telescopic arm which is easy to extend by using hydraulics. The lattice boom should be manually assembled by adding multiple sections.
Tower Cranes
Tower cranes are the ones found in big construction projects. These types of cranes are essential to be built and broken down on location. They must be transported by truck every time they are relocated. These tower cranes are exceptionally tall. They enable construction crews to move heavy steel or concrete building components to the tops of tall buildings. Tower cranes utilize a hydraulic system to be able to push each new crane section up into place and therefore, are self-erecting.
