What Exactly Is an Articulating Boom Lift?
The articulated boom lift is a heavy duty machinery capable of performing numerous tasks from electrical repair to construction applications. These extremely maneuverable lifts make working at heights a lot efficient and safer.
Height
Knuckle boom lifts are a different term used for articulating boom lifts. These machines are capable of reaching heights from thirty six feet to 131 feet, depending on the model of the specific lift.
Design
The articulating boom has a huge arm or boom with many bending elbows. These are in conjunction with extendable arms that enable the articulating lifts to reach over objects and outwards as well as upwards.
Telescoping vs. Articulating
Telescoping or straight boom lifts have a working height which 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 are able to be reached with it.
Advantages
The design of the articulating boom lift helps to ensure it could negotiate around objects and obstacles. These lifts are offered in electrical models, have zero tail swing and are convenient for indoor use. These specific kinds of lifts are ideal for crowded work situations.
SJ 46AJ
Skyjack has made the A-Series Articulating Boom with many of their most reliable and efficient design features. The SJ 46AJ provides an industry leading, three hundred sixty degree continuous turret rotation that is standard equipped. Due to the turret design allowing for easy operation in tight spaces, this specific model also offers zero tail swing.
Skyjack is popular for its extreme terrains and positive traction. A lot of their machines offer axle based 4WD. These machines 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 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 range of machines, industrial wheel tractors were modified during the 1920s, by Fordson and McCormick-Deering. Like for instance, half-swing shovels and cranes were manufactured by several companies around the power train and engine of the tractor and the wheels became replaced by crawlers.
Crawler tractors came into widespread use during the nineteen thirties. Immediately after, numerous manufacturers began manufacturing attachments for them, like a variety 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 outstanding lifting capacity, these machines are great for this use. Furthermore, swing booms which mounted on top of the engine compartment also became available.
Similar to a crawler tractor, crawler cranes travel on crawler tracks. Because of their intense weight, these equipments do not move really fast. Usually, the crane may be controlled by 2 or more cable operated drums and is powered by one engine. The crawler cranes come equipped with a telescopic arm or a lattice boom that is easy to extend by utilizing hydraulics. The lattice boom must be assembled by hand by adding many sections.
Tower Cranes
Tower cranes are the ones found in large construction projects. These kinds of cranes are necessary to be erected and broken down on location. They should be transported by truck every time they are relocated. These tower cranes are very 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 in order to push each new crane part up into place and hence, are self-erecting.
