What feature do scissor lifts typically not have compared to boom lifts?

Scissor lifts are designed primarily for vertical lifting and do not have outreach capability like boom lifts, which can extend their platform out horizontally. This is a fundamental difference in design and function between the two types of equipment. Boom lifts are equipped with extendable arms that allow operators to reach out over obstacles, making them ideal for tasks that require both height and horizontal reach.

In contrast, scissor lifts have a platform that elevates straight up and down, without the ability to extend out over a distance. This limitation is a key characteristic that distinguishes scissor lifts from boom lifts, as scissor lifts are best suited for work that is directly above their base and does not require any side access.

Height adjustment is a standard feature in both types of lifts, as is the inclusion of built-in safety alarms to alert operators to potential hazards. Stabilizing legs may be used in both types to provide additional stability, but they are not exclusive to one type over the other. Hence, the lack of outreach capability is what sets scissor lifts apart in this context, making it the correct choice.
