What Exactly Is an Articulating Boom Lift?
The articulated boom lift is a heavy duty equipment capable of performing numerous tasks from electrical repair to construction applications. These extremely maneuverable lifts make working at heights a lot safer and efficient.
Height
Knuckle boom lifts are a different term for articulating boom lifts. These machines can reach heights from 36 feet to 131 feet, depending on the model of the specific lift.
Design
The articulating boom has a huge boom or arm with many bending elbows. These are in conjunction with extendable arms which enable the articulating lifts to reach outwards and over objects as well as upwards.
Articulating vs. Telescoping
Both telescoping or straight boom lifts can 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 that 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 have zero tail swing, are convenient for indoor application and offered in electrical models. These particular types 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 reliable and efficient 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 areas, this model also provides zero tail swing.
Skyjack is recognized for providing positive traction and extreme terrain ability. These features are offered by the axle based 4WD, which is offered in many of Skyjack's product designs. 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 unlock and lock switch. This enables the operator to lock the rear differential when traveling on rough ground.
Different Types of Crawler-Mounted Cranes
Industrial wheel tractors during the nineteen twenties, like those made by McCormick-Deering and Fordson were rapidly modified in order to be able to power a huge variety of machinery. Like for example, half-swing shovels and cranes were made by some companies around the engine and power train of the tractor and the wheels became replaced by crawlers.
During the nineteen thirties, crawler tractors came into widespread use. Soon after, many manufacturers started making attachments for them, like for example various 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 usually used today for attending to cleaning up railroad derailments. Because of their size, compact design and mobility, as well as outstanding lifting capacity, these types of machinery are great for this application. Additionally, swing booms that 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 equipments do not move very fast. Normally, the crane is powered by one engine and can be controlled by 2 or more cable operated drums. The crawler cranes come outfitted with a lattice boom or a telescopic arm that is easy to extend by utilizing hydraulics. The lattice boom should be assembled by hand by adding multiple sections.
Tower Cranes
Usually found in big construction projects, tower cranes are required to be erected and broken down on location. They should be transported by truck each and every time they are relocated. These tower cranes are very tall. They enable construction crews to move concrete building parts or heavy steel to the tops of tall buildings. Tower cranes use a hydraulic system to push every new crane section up into position and therefore, are self-erecting.
