Disadvantages of Scissor Lifts
A scissor lift is a specific kind of mobile scaffolding. This wheel-mounted machine gives power to a work platform which moves down and up. The lift can be powered by electricity, propane, gas or diesel. Scissor lifts are characterized by various scissor-like joints that raise the machinery by expanding and collapsing. Lots of safety features are built into scissor lifts today, specially the newer models. Like with any safety features, they might not be able to guarantee safety and several features could sometimes malfunction or they can be overridden by operators manually.
Accidental Elevation
Normally, construction workers use scissor lifts to work on ceilings or on higher aspects of the jobsite. The workers would have to lift the platforms just to right below ceiling level. The issue with accidental elevation could happen if the workers bump into the elevation controls accidentally when working. In the ceiling scenario, the controls might be accidentally activated and the platform can rise up and inadvertently crush them into the ceiling.
Electrocution
Workers need to be extremely careful, making sure they are completely aware of their surroundings. This will ensure they don't inadvertently electrocute themselves. If, for instance, the operator inadvertently touches or makes direct contact with an induction field or an electrical conductor, terrible consequences can occur.
Lateral Loads
When operating a scissor lift, it is essential to be familiar with the loading restrictions in the instruction manual of your scissor lift. Very terrible consequences could occur if the platform is mis-loaded. A lateral-load is amongst the potential issues that could take place if the entire lift overturns. This situation occurs when a heavy tool or material like a concrete slab that hangs over the side of a scissor lift platform, causing the whole equipment to become instantly unbalanced and really susceptible to dangerously tipping over.
