freight elevator

A freight elevator is a type of elevator designed to transport goods between different levels of a building. These elevators are crucial for moving materials in various settings, from warehouses to department stores.

Historically, lifting platforms for loads existed as far back as Roman times, initially powered by human, animal, or water power. By 1800, steam power was applied, and later, hydraulic lifts were introduced. However, these early systems were primarily for freight due to the unreliability of ropes for passenger use. The invention of a safety device in the mid-1850s made passenger elevators feasible, but freight elevators continued to evolve, with modern versions often utilizing electric motors and robust cable systems for reliable vertical transportation of goods. Hydraulic elevators are also commonly used for freight in low-rise buildings due to their lower cost.12
