What Is an Articulating Boom Lift?
The articulated boom lift is a heavy duty equipment capable of performing various tasks from construction applications to electrical repair. These extremely maneuverable lifts make working at heights much efficient and safer.
Height
Articulating booms are also referred to 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
Articulating boom lifts are designed with many bending elbows. These are in conjunction with extendable arms that allow the articulating lifts to reach outwards and over things as well as upwards.
Telescoping vs. Articulating
Telescoping or straight boom lifts have a working height that ranges from 46 to 86 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 can be reached with it.
Advantages
The design of the articulating boom lift helps to ensure it can negotiate around obstacles and objects. These lifts have zero tail swing, are convenient for indoor use and offered in electrical models. These specific kinds of lifts are ideal 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. because of the turret design allowing for easy operation in tight areas, this particular model also offers zero tail swing.
Skyjack is recognized for offering positive traction and extreme terrain ability. These features are provided by the axle based 4WD, which is offered in many of Skyjack's product designs. These machinery are known for having a rugged and reliable drive train and proven low maintenance. In addition, the AJ has been designed with a rear axle hydraulic differential lock and unlock switch. This enables the operator to lock the rear differential when traveling on rough terrain.
Various Types of Crawler-Mounted Cranes
In order to be able to power a huge range of machines, industrial wheel tractors were modified during the 1920s, by Fordson and McCormick-Deering. For instance, half-swing shovels and cranes were manufactured by several companies around the tractor's engine and power train and the wheels became replaced by crawlers.
In the 1930s, crawler tractors came into widespread use. Immediately after, many manufacturers began manufacturing attachments for them, such as a range of lifting equipment devices.
For instance, side-mounted booms were mainly used for pipe-laying where it gained its nickname the "pipelayer." These machines are frequently used today for attending to cleaning up railroad derailments. Because of their size, compact design and mobility, as well as outstanding lifting capacity, these kinds of machinery are ideal for this use. Furthermore, swing booms that mounted on top of the engine compartment became available too.
Similar to a crawler tractor, crawler cranes travel on crawler tracks. Because of their intense weight, these machines do not move really fast. Typically, the crane can be controlled by 2 or more cable operated drums and is powered by one engine. The crawler cranes come outfitted with a telescopic arm or a lattice boom which could be extended easily using hydraulics. The lattice boom must be manually assembled by adding many sections.
Tower Cranes
Typically found in large construction projects, tower cranes are required to be erected and broken down on location. They should 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 use a hydraulic system to push each new crane section up into place and thus, are self-erecting.
