Disadvantages of Using Scissor Lifts
Scissor lifts are a kind of "mobile scaffolding", with a wheel-mounted equipment that gives power to a work platform which moves down and up. The lift can be powered by propane, electricity, gas or diesel. Scissor lifts are characterized by a variety of scissor-like joints that raise the machine by collapsing and expanding. Many safety features are built into scissor lifts today, specially models that are newer. Like with any safety features, they might not be able to guarantee safety and several features can sometimes malfunction or they could be overridden by operators manually.
Accidental Elevation
Normally, construction workers use scissor lifts to work on higher aspects of the jobsites or on ceilings. The workers would need to raise the platforms just to right beneath ceiling level. The issue with accidental elevation could happen if the workers inadvertently bump into the elevation controls while working. In the ceiling scenario, the controls could be accidentally activated and the platform could rise up and accidentally crush them into the ceiling.
Electrocution
Workers have to be very careful, making sure they are completely aware of their surroundings. This would ensure they don't accidentally electrocute themselves. If, for instance, an operator makes direct contact with or inadvertently touches an induction field or an electrical conductor, terrible outcome can take place.
Lateral Loads
It is important to be familiar with the loading restrictions when in operation of the scissor lift. These limitations would be labelled in the scissor lift guidebook. Mis-loading the platform could cause extremely serious consequences. A lateral-load is amongst the potential problems that can happen if the whole lift overturns. This situation happens if a heavy material or tool like a concrete slab that hangs over the side of a scissor lift platform, causing the entire machine to become unbalanced at once and greatly susceptible to tipping over dangerously.
