Aerial Manlift Dangers
Aerial man lifts are personnel lifts like boom lifts, articulated boom lifts and scissor lifts that utilize an articulated boom or a series of linked, folding supports. These equipment enables employees to get up high into previously inaccessible areas. In some ways, these machines have made construction much easier and safer, although, the overall safety that comes with the unparalleled mobility of aerial manlifts has implemented a new list of dangers which could accidentally cause serious injury or even death to drivers who are unaware.
Falls
Falls from a man lift usually happens when employees cannot secure the harness to the lift or fail to or are unable to wear a safety harness. 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 added height. In addition, accidents could be caused if the operator on the ground causes the machine to move in an unexpected motion prior to the employee being properly secured.
Sometimes employees can fall when the lift's base is struck inadvertently by a heavy object. During this situation, the force of the blow below becomes amplified by the length of the lift, therefore causing the worker to be abruptly catapulted off of the platform. Clearly this hazardous action has catastrophic results.
Tip-Overs
Unfortunately, boom lifts are easily prone to tipping over. Tip-overs could occur in any kind of lift, but are more common in articulated boom lifts. As boom lifts are able to move both vertically and horizontally, they could change the overall center of gravity of the equipment. Therefore, if the lift is over loaded or parked on a slope of some sort, completely extending the boom when it is in the wrong position could cause the equipment to tip over.
