Disadvantages of Scissor Lifts
A scissor lift is a specific type of mobile scaffolding. This wheel-mounted equipment gives power to a work platform which moves up and down. The lift can be powered by electricity, propane, diesel or gas. Scissor lifts are characterized by a variety of scissor-like joints that raise the machine by expanding and collapsing. Many safety features are built into scissor lifts today, specially models which are newer. As with any safety features, they may not be able to guarantee safety and some features could be manually overridden by operators or they can occasionally malfunction.
Inadvertent Elevation
Commonly, construction workers utilize scissor lifts to work on ceilings or on higher aspects of the jobsite. The workers would need to hoist the platforms just to right below ceiling level. The problem with accidental elevation can occur if the workers bump into the elevation controls inadvertently when working. In the ceiling scenario, the controls could be activated accidentally and the platform can rise up and accidentally 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 utilizing the machinery in order to ensure they don't accidentally electrocute themselves. If, for instance, an operator inadvertently touches or makes direct contact with an induction field or an electrical conductor, tragic outcome can happen.
Lateral Loads
It is essential to be familiar with the loading limitations while using the scissor lift. These limitations will be labelled in the scissor lift guidebook. Mis-loading the platform could lead to extremely serious consequences. A lateral-load is among the possible issues which could occur if the entire lift overturns. This situation takes place when a heavy tool or material such as a concrete slab that hangs over the side of a scissor lift platform, causing the entire equipment to become unbalanced at once and really susceptible to dangerously tipping over.
