What Is an Articulating Boom Lift?
An articulating boom lift is an industrial equipment which is used in various applications from electrical repair to construction. These highly maneuverable lifts make working at heights a lot safer and efficient.
Height
Articulating booms are also called knuckle boom lifts. These equipment can reach heights from thirty six feet to 131 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 which allow the articulating lifts to reach outwards and over objects as well as upwards.
Telescoping vs. Articulating
Straight or telescoping boom lifts have a working height that ranges from 46 to 86 feet. Unlike 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 design of the articulating boom lift helps to ensure it can negotiate around obstacles and objects. These lifts are convenient for indoor use, available in electrical models and have zero tail swing. These specific kinds 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 reliable and effective design features. The SJ 46AJ provides 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 offers zero tail swing.
Skyjack is popular for its positive traction for extreme terrains. A lot of their equipment offer axle based 4WD. These machinery are known for having a rugged and reliable drive train and proven low maintenance. Additionally, 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.
Different Types of Crawler-Mounted Cranes
In order to be able to power a huge variety of machines, industrial wheel tractors were adapted in the nineteen twenties, by Fordson and McCormick-Deering. For example, half-swing shovels and cranes were manufactured by several companies around the tractor's power train and engine and the wheels became replaced by crawlers.
Crawler tractors came into widespread use in the 1930s. Immediately after, many manufacturers began manufacturing attachments for them, including a range of lifting machine devices.
Side-mounted booms for example, were used mainly for pipe-laying at first and the machinery got the nickname "pipelayer." These equipments are now normally used for attending to cleaning up railroad derailments. Due to their mobility, size and compact design, as well as excellent lifting capacity, these types of machines are ideal for this use. Additionally, swing booms which mounted on top of the engine compartment also became available.
LIke a crawler tractor, crawler cranes travel on crawler tracks. Due to their intense weight, these machines do not move very fast. Usually, the crane is powered by one engine and may be controlled by 2 or more cable operated drums. The crawler cranes come outfitted with a telescopic arm or a lattice boom that is easy to extend by utilizing hydraulics. The lattice boom must be assembled manually by adding many sections.
Tower Cranes
Usually found in large construction projects, tower cranes are required to be erected and broken down on location. They need to be transported by truck each time they are relocated. These tower cranes are very tall. They enable construction crews to transport heavy steel or concrete building parts to the tops of tall buildings. Tower cranes use a hydraulic system to be able to push each and every new crane section up into place and hence, are self-erecting.
