Aerial Manlift Dangers
Aerial man lifts are personnel lifts like scissor lifts, boom lifts, and articulated booms lifts which use an articulated boom or a series of folding, linked supports. These machinery enables workers to get up high into previously inaccessible places. In certain ways, these equipment have made construction a lot safer and easier, however, the overall safety which comes with the unparalleled mobility of aerial manlifts has applied a new list of dangers that could inadvertently lead to serious injury or even death to unaware operators.
Falls
Falls from a man lift normally happens when employees 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 wrongly and partakes in an activity like climbing the guard rails to be able to gain extra height. In addition, mishaps can be caused if the ground-based operator causes the equipment to move in an unexpected motion before the worker being properly secured.
Many workers also fall because the base of their machinery is inadvertently struck by some other heavy thing. During this situation, the force of the blow below becomes amplified by the lift's length, therefore 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 happen in any type of lift. Because boom lifts are able to move both vertically and horizontally, they are capable of changing the overall center of gravity of the machine. Hence, if the lift is over loaded or parked on an incline of some sort, extending the boom completely when it is in the wrong position can cause the machine to tip over.
Boom trucks are somewhat similar to cranes and can be equipped with a winch for lifting. This would depend upon the weight and size of the vehicle, that determines the type of cargo which could be carried. Because of the capability of their size, cranes can usually raise a lot larger loads. The advantage of boom trucks is that they can be driven to work locations and are mobile which make them a lot more versatile. Furthermore, a boom truck can be equipped with a bucket and can also lift personnel as well as supplies up to high locations. Like for instance, boom trucks are usually found raising utility and maintenance staff on a telephone pole.
Types
There are various kinds of boom trucks. There are times when the term "boom truck" is synonymously used with vehicles which perform the same functions. Like for instance, aerial work platforms which are mounted to the bed of a truck which utilizes hydraulic lifts can be referred to as a boom truck. Other people can refer to a regular utility truck utilized to raise workers to a utility a boom truck. Whether the truck operates on treads or wheels, uses a bucket or a winch, they are still able to lift supplies and workers 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 require a heavy lifting vehicle. A boom truck crane is able t lift different weights. These machinery remain stationary when lifting.
Crane
Bigger cranes are large lifting devices used for moving goods or materials and are normally used to move construction materials also. They are common features in the the construction industry, the manufacturing industries and the transportation industries. Cranes use chains, cables, wires or ropes connected to a winder. The load capacity depends on the crane type. The highest load capacity is provided by big fixed chains.
