What Is an Articulating Boom Lift?
The articulated boom lift is a heavy duty equipment capable of performing numerous jobs from construction applications to electrical repair. These highly maneuverable lifts make working at heights much efficient and safer.
Height
Knuckle boom lifts are another term used for articulating boom lifts. These machines are capable of reaching heights from 36 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 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 can be reached with it.
Advantages
The articulating boom lift design makes them the most able to negotiate around obstacles and objects. These lifts have zero tail swing, are convenient for indoor use and available in electrical models. 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 effective 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 areas, this model also provides zero tail swing.
Skyjack is popular for its extreme terrains and positive traction. Many of their equipment offer axle based 4WD. These machines are known for having a dependable and rugged drive train and proven low maintenance. In addition, the AJ has been designed with a rear axle hydraulic differential lock and unlock switch. This allows the operator to lock the rear differential when traveling on rough terrain.
Other KInds of Crawler-Mounted Cranes
Industrial wheel tractors in the nineteen twenties, including those built by Fordson and McCormick-Deering were rapidly adapted so as to be able to power a huge variety of equipment. For example, half-swing cranes and shovels were made by several companies around the engine and power train of the tractor and the wheels became replaced by crawlers.
Crawler tractors came into widespread use during the nineteen thirties. Soon after, many manufacturers started making attachments for them, like various lifting machine devices.
For example, side-mounted booms were primarily used for pipe-laying where it gained its nickname the "pipelayer." These machinery are currently normally used for attending to cleaning up railroad derailments. Because of their size, compact design and mobility, as well as outstanding lifting capacity, these types of equipments are ideal for this application. In addition, swing booms that mounted on top of the engine compartment became available too.
Crawler cranes are similar to the crawler tractor in that it travels along crawler tracks. These equipments could not move fast thanks to their intense weights. Usually, the crane is powered by one engine and may be controlled by 2 or more cable operated drums. The crawler cranes are available with a telescopic arm or a lattice boom which can be extended easily using hydraulics. The lattice boom should be manually assembled by adding many sections.
Tower Cranes
Usually found in big construction projects, tower cranes are required to be erected and broken down on location. They have to be transported by truck each and every time they are relocated. These tower cranes are exceptionally tall. They enable construction crews to transport concrete building parts or heavy steel to the tops of tall buildings. Tower cranes utilize a hydraulic system to push every new crane section up into position and thus, are self-erecting.
