Aerial Manlift Dangers
Aerial man lifts are personnel lifts like articulated boom lifts, scissor lifts and boom lifts which utilize an articulated boom or a series of linked, folding supports. These machinery enables workers to get up high into previously inaccessible places. In some ways, these equipment have made construction a lot easier and safer, however, the overall safety that comes with the unparalleled mobility of aerial manlifts has applied a new list of dangers that can inadvertently lead to serious injury or even death to unaware operators.
Falls
Falls from a man lift usually occurs when employees cannot secure the harness to the lift or fail to or are unable to wear a safety harness. Falls could happen when somebody on the platform acts unsuitably and partakes in an activity such as climbing the guard rails to gain additional height. Additionally, accidents can be caused if the ground-based operator causes the machinery to move in an unexpected motion before the employee being properly secured.
Sometimes workers can fall when the base of the lift 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 employee to be suddenly catapulted off of the platform. Obviously this hazardous action has catastrophic outcome.
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 can move both vertically and horizontally, they are capable of changing the machinery's overall center of gravity. Hence, if the lift is over loaded or parked on a slope of some kind, extending the boom to full length when it is in the wrong position can cause the machinery to tip over.
