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
Knuckle boom lifts are a different term used for articulating boom lifts. These machinery are capable of reaching heights from 36 feet to one hundred thirty one feet, depending on the model of the specific lift.
Design
The articulating boom has a large boom or arm with many bending elbows. These are in conjunction with extendable arms which allow the articulating lifts to reach over things and outwards as well as upwards.
Telescoping vs. Articulating
Both straight or telescoping boom lifts could work at heights from 46 to 86 feet. Not like articulating lifts, these ones do not contain 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 design of the articulating boom lift helps to ensure it can 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 using many of their dependable and effective design features. The SJ 46AJ offers an industry leading, 360 degree continuous turret rotation that is standard equipped. Thanks to the turret design allowing for easy operation in tight spaces, this specific model also offers zero tail swing.
Skyjack is popular for its positive traction for extreme terrains. Many of their machines provide axle based 4WD. These equipment 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 lock and unlock switch. This enables the operator to lock the rear differential when traveling on rough ground.
Other KInds of Crawler-Mounted Cranes
Industrial wheel tractors during the nineteen twenties, such as those made by Fordson and McCormick-Deering were quickly adapted in order to be able to power a huge range of machinery. For instance, half-swing cranes and shovels were made by several companies around the power train and engine of the tractor and the wheels became replaced by crawlers.
Throughout the nineteen thirties, crawler tractors came into widespread use. Soon after, numerous manufacturers started manufacturing attachments for them, including a variety of lifting machine devices.
Side-mounted booms for instance, were used mainly for pipe-laying at first and the machine got the nickname "pipelayer." These types of equipments are frequently utilized nowadays for attending to cleaning up railroad derailments. Due to their mobility, size and compact design, as well as exceptional lifting capacity, these machines are ideal for this application. Moreover, swing booms which mounted on top of the engine compartment also became available.
Crawler cranes are similar to the crawler tractor in that it travels along crawler tracks. These machines can not move fast due to their intense weights. Typically, the crane could 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 is easy to extend by utilizing hydraulics. The lattice boom should be assembled manually 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 have to be transported by truck every time they are relocated. These tower cranes are very tall. They enable construction crews to transport heavy steel or concrete building components to the tops of tall buildings. Tower cranes use a hydraulic system to be able to push every new crane part up into place and thus, are self-erecting.
