"scissor lift"的定义和意义

What is a "scissor lift"?

A scissor lift is a type of platform that can be raised and lowered vertically, usually to provide access to high areas for work or maintenance. It consists of a platform supported by a crisscrossing set of metal arms, or "scissors," which expand and contract to lift or lower the platform. Scissor lifts are powered by electricity, hydraulics, or air pressure, and are commonly used in construction and warehouses for tasks like painting, repairs, or installations at height. They are designed to provide a stable and safe working surface, offering greater reach compared to ladders.
