Disadvantages of Scissor Lifts
Scissor lifts are a kind of "mobile scaffolding", with a wheel-mounted machinery that gives power to a work platform that moves down and up. The lift can be powered by propane, electricity, gas or diesel. Scissor lifts are characterized by various scissor-like joints which elevate the equipment by expanding and collapsing. Numerous safety features are built into modern scissor lifts, especially the newer models. As 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
Construction workers normally use scissor lifts to work at higher heights. Workers could lift the work platform to just below the ceiling level. The problem with accidental elevation can happen if the workers bump into the elevation controls accidentally when working. In the ceiling scenario, the controls might be activated accidentally and the platform could rise up and inadvertently crush them into the ceiling.
Electrocution
Another way workers have to be very careful is to be sure they are familiar with the environment they are in while using the machine so as to ensure they don't accidentally electrocute themselves. If, for instance, the operator makes direct contact with or inadvertently touches an electrical conductor or an induction field, terrible outcome could occur.
Lateral Loads
While utilizing a scissor lift, it is vital to be familiar with the loading restrictions in the guidebook of your scissor lift. Very serious consequences can take place if the platform is mis-loaded. A lateral-load is one of the potential issues that could take place if the entire lift overturns. This situation takes place when a heavy tool or material like for instance a concrete slab which hangs over the scissor lift platform's side, causing the whole machine to become unbalanced right away and greatly susceptible to tipping over dangerously.
