Aerial Manlift Dangers
Aerial man lifts are personnel lifts such as boom lifts, articulated boom lifts and scissor lifts which utilize an articulated boom or a series of linked, folding supports. These machinery allows employees to get up high into previously inaccessible places. In some ways, these kinds of machinery have made construction much safer and easier, however, the overall safety which comes with the unparalleled mobility of aerial manlifts has implemented a new list of hazards which can inadvertently lead to severe injury or even death to unaware drivers.
Falls
Falls from a man lift normally happens when workers fail to or are unable to wear a safety harness or cannot secure the harness to the lift. Falls can take place when a worker on the platform acts inappropriately and partakes in an activity like for instance climbing the guard rails in order to gain additional height. Also, mishaps could be caused if the ground-based operator causes the machinery to move in an unexpected motion prior to the worker being properly secured.
At times employees could fall when the base of the lift is struck accidentally by a heavy thing. During this situation, the force of the blow below becomes amplified by the lift's length, therefore causing the worker to be suddenly catapulted off of the platform. Obviously this dangerous action has terrible results.
Tip-Overs
Boom lifts are prone to tipping over. Tip overs are more frequent in articulated boom lifts, but can occur in any kind of lift. As boom lifts are able to move both horizontally and vertically, they could change the machinery's overall center of gravity. Therefore, if the lift is over loaded or parked on a slope of some sort, extending the boom to full length when it is in the wrong position could lead to a tip-over situation.
Similar to cranes, boom trucks could be equipped with a winch for lifting. It depends on the vehicle size and weight determines the kind of load which could be raised. Because of the potential of their size, cranes can usually lift a lot bigger loads. The advantage of boom trucks is that they are mobile and can be driven to work areas which make them a lot more versatile. Additionally, a boom truck can be outfitted with a bucket and can also lift employees as well as supplies up to high places. For instance, boom trucks are normally found lifting utility and maintenance workers on a telephone pole.
Kinds
There are a variety of different kinds of boom trucks. There are times when the term "boom truck" is synonymously used with vehicles which carry out similar functions. Like for example, aerial work platforms that are mounted to the bed of a truck which uses hydraulic lifts can be called a boom truck. Other people may refer to a typical utility truck used to raise employees to a utility a boom truck. Whether the truck uses a winch or a bucket, operates on treads or wheels, they could still lift employees and supplies vertically.
Boom Truck Crane
The boom truck crane is used like a crane but is classed as a boom truck. Often, these kinds of 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 is able t lift different weights. These equipment remain in position when lifting.
Crane
Larger cranes are large lifting devices utilized for moving materials or goods and are normally used to transport construction materials also. They are popular features in the the construction industry, the manufacturing industries and the transportation industries. Cranes use ropes, wires, cables or chains connected to a winder. The load capacity depends on the type of crane. The highest load capacity is provided by large fixed chains.
