Aerial Manlift Dangers
Aerial man lifts are personnel lifts such as boom lifts, articulated boom lifts and scissor lifts that utilize an articulated boom or a series of linked, folding supports. These equipment allows workers to get up high into previously inaccessible places. In some ways, these kinds of machinery have made construction much easier and safer, however, the general safety that comes with the unparalleled mobility of aerial manlifts has implemented a new list of dangers which could accidentally cause severe injury or even death to operators who are unaware.
Falls
Falls from a man lift usually occurs when workers fail to or are unable to wear a safety harness or cannot secure the harness to the lift. Falls can happen when somebody on the platform acts wrongly and participates in an activity like for instance climbing the guard rails in order to gain extra height. In addition, accidents could be caused if the ground-based operator causes the equipment to move in an unexpected motion prior to the worker being properly secured.
At times employees can fall when the base of the lift is struck inadvertently by a heavy thing. During this situation, the force of the blow below becomes amplified by the lift's length, thus causing the worker to be abruptly catapulted off of the platform. Obviously this hazardous action has terrible results.
Tip-Overs
Boom lifts are susceptible to tipping over. Tip overs are more frequent in articulated boom lifts, but could take place in any kind of lift. Since boom lifts can move both horizontally and vertically, they could change the machine's overall center of gravity. Thus, if the lift is parked on a slope of some sort or over loaded, extending the boom completely when it is in the wrong position can result in a tip-over situation.
Boom trucks are quite similar to cranes and could be outfitted with a winch for lifting. This would depend upon the weight and size of the vehicle, that determines the type of load which could be lifted. Because of the capability of their size, cranes can normally raise a lot bigger loads. The benefit of boom trucks is that they are mobile and could be driven to work locations that make them much more versatile. Furthermore, a boom truck can be equipped with a bucket and can also raise supplies as well as workers up to high locations. Like for instance, boom trucks are normally found lifting utility and maintenance workers on a telephone pole.
Types
Boom Trucks come in numerous varieties. Occasionally, the term "boom truck" is utilized synonymously used with other vehicles that perform other similar functions. For instance, aerial work platforms that are mounted to the bed of a truck which utilizes hydraulic lifts could be called a boom truck. Other individuals might call a standard utility truck utilized to lift employees to a utility a boom truck. Whether the truck operates on wheels or treads, uses a winch or a bucket, they can still lift materials and employees vertically.
Boom Truck Crane
The boom truck crane is used like a crane but is classed as a boom truck. Often, these vehicles are found in hard to reach places and areas which are difficult to reach, which need a heavy lifting vehicle. A boom truck crane can lift different weights. These machinery remain stationary when lifting.
Crane
Larger cranes are big lifting devices utilized for moving materials or goods and are often used to transport construction materials too. They are common features in the the transportation industries, in the construction industry and the manufacturing industries. Cranes use wires, ropes, chains or cables connected to a winder. The load capacity depends on the crane type. The highest load capacity is provided by big fixed chains.
