Disadvantages of Using Scissor Lifts
Scissor lifts are a kind of "mobile scaffolding", with a wheel-mounted machine which provides power to a work platform that moves up and down. The lift could be powered by electricity, propane, gas or diesel. Scissor lifts are characterized by various scissor-like joints which elevate the equipment by collapsing and expanding. Many safety features are built into scissor lifts today, particularly the newer models. As with any safety features, they might not be able to guarantee safety and some features could sometimes malfunction or they can be manually overridden by operators.
Inadvertent Elevation
Commonly, 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 below ceiling level. The issue with accidental elevation can occur if the workers inadvertently bump into the elevation controls while working. In the ceiling scenario, the controls could be accidentally activated and the platform can rise up and inadvertently crush them into the ceiling.
Electrocution
Another way workers need to be really cautious is to be sure they know the environment they are in while utilizing the equipment so as to make certain they don't unintentionally electrocute themselves. If, for instance, the operator accidentally touches or makes direct contact with an electrical conductor or an induction field, tragic consequences could happen.
Lateral Loads
It is essential to know the loading limitations while utilizing the scissor lift. These restrictions will be labelled in the scissor lift handbook. Mis-loading the platform could result in very terrible consequences. A lateral-load is among the possible problems which can happen if the entire lift overturns. This situation occurs if a heavy tool or material such as a concrete slab which hangs over the scissor lift platform's side, causing the entire machine to become unbalanced right away and greatly prone to tipping over dangerously.
