Aerial Manlift Dangers
Aerial manlifts are machines that utilize either a series of linked, folding supports, like a boom lift or an articulated boom lift or a scissor lift. These industrial types of machine allow workers to get in touch with hard-to-reach areas. In some ways, these types of equipment have made construction a lot easier and safer, although, the general safety that comes with the unparalleled mobility of aerial manlifts has implemented a new list of dangers which could inadvertently lead to severe injury or even death to unaware drivers.
Falls
Normally, falls could happen when employees are unable to wear a safety harness or are unable to correctly secure the lift platform. Falls can occur when a worker on the platform acts wrongly and partakes in an activity such as climbing the guard rails in order to gain additional height. Additionally, mishaps could be caused if the operator on the ground causes the equipment to move in an unexpected motion prior to the employee being correctly secured.
Sometimes employees may fall when the base of the lift is struck accidentally by a heavy object. 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. Clearly this dangerous action has catastrophic results.
Tip-Overs
Unfortunately, boom lifts are easily prone to tipping over. Tip-overs could happen in any kind of lift, but are more frequent in articulated boom lifts. Since boom lifts could move both vertically and horizontally, they can change the machinery's overall center of gravity. Thus, if the lift is parked on an incline of some sort or over loaded, completely extending the boom when it is in the wrong position can cause the machine to tip over.
Like 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 can be lifted. Because of the potential of their size, cranes can usually raise loads which are a lot bigger. The advantage of boom trucks is that they are mobile and could be driven to work areas that make them much more versatile. In addition, a boom truck can be equipped with a bucket and could also lift personnel as well as supplies up to high locations. For example, boom trucks are commonly found lifting utility and maintenance staff on a telephone pole.
Types
There are various types of boom trucks. There are times when the term "boom truck" is synonymously utilized with vehicles which perform the same functions. Like for example, aerial work platforms which are mounted to the bed of a truck that uses hydraulic lifts may be referred to as a boom truck. Other people may refer to a regular utility truck used to lift employees to a utility a boom truck. Whether the truck operates on wheels or treads, uses a winch or a bucket, they are still able to lift materials and workers vertically.
Boom Truck Crane
The boom truck crane is utilized 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, that require a heavy lifting vehicle. A boom truck crane is able t lift various weights. These types of equipment remain stationary when lifting.
Crane
Bigger cranes are large lifting devices used for transporting materials or goods and are usually utilized to transport construction materials as well. They are common features in the the transportation industries, in the construction industry and the manufacturing industries. Cranes utilize ropes, wires, cables or chains connected to a winder. The load capacity depends on the kind of crane. The highest load capacity is provided by large fixed chains.
