Scissor lifts have interfaces that allow height adjustment at the discretion of the operator, though a small number of lift tables may have reconfigure lift heights. Many lifts incorporate a safety mechanism to prevent uncontrolled descent. Lifts responsible for cargo provide a height governor determined to remove the user from inherent dangers. Scissor lifts are also used by personnel for access to irregular, raised workspaces. In these instances the control interface is located within the lift carriage and requires a key for ignition. Elevation and steering command is frequently controlled by a single joystick with a toggle. Some lifts may have an extendable, articulated, or rotating platform to compensate for its horizontal limitations. Auxillary controls within the lift’s base offer inspection and troubleshooting capabilities.
Scissor Lift Portability
Motor-driven propulsion is a valuable attribute in many situations requiring scissor lifts. This allows workers to position the lift on an as-needed basis which is particularly useful in maintenance and construction applications. ‘Slab’ scissor lifts are restricted to paved, smooth surfaces; rough terrain lifts rely on robust tires and four-wheel drive to traverse off-road conditions.
To improve lift agility, manufacturers rely on a sharp turning radius and a short wheelbase. Parking brakes ensure lift location, and tires and casters come in non-marking, off-road, anti-slip, press-on, and urethane varieties. Economical and legal reasons prohibit scissor lifts from road travel; they are hauled or towed between job sites. However, some scissor lifts may be flatbed or railcar-mounted for specialty applications. Many mobilized lifts utilize outriggers for further foundational stability.
