Aerial Manlift Dangers
Aerial man lifts are personnel lifts such as articulated boom lifts, scissor lifts and boom lifts that utilize an articulated boom or a series of folding, linked supports. These machines allows workers to get up high into previously inaccessible places. In certain ways, these machines have made construction much easier and safer, however, the overall safety which comes with the unparalleled mobility of aerial manlifts has applied a new list of hazards which can inadvertently result in serious injury or even death to drivers who are unaware.
Falls
Falls from a man lift usually occurs when workers cannot secure the harness to the lift or fail to or are unable to wear a safety harness. Falls can occur when a worker on the platform acts inappropriately and partakes in an activity like climbing the guard rails to gain additional height. What's more, accidents could be caused if the operator on the ground causes the equipment to move in an unexpected motion before the employee being properly secured.
At times workers may 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 length of the lift, therefore causing the worker to be suddenly 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 take place in any type of lift, but are more frequent in articulated boom lifts. Since boom lifts can move both vertically and horizontally, they could change the machinery's overall center of gravity. Therefore, if the lift is over loaded or parked on an incline of some kind, totally extending the boom when it is in the wrong position could cause the equipment to tip over.
