Limited Use / Limited Access

A limited use/limited application LU/LA) elevator is a fully-enclosed power passenger elevator in which the use and application is limited by size, capacity, speed and rise. These low-rise elevator systems bridge the gap between conventional commercial elevators and undesirable lifts used to provide solutions for architectural barriers.

Custom’s roped 1:2 hydraulic design provides the quietest and smoothest operation in the industry. This system utilizes components and devices that are tested and certified to the most stringent requirements and have been tried and proven on commercial mid-rise elevator applications subject to more frequent use.

Custom’s unique design minimizes hoistway space, machine room space, pit depth, overhead clearances and operates on standard single phase power. This makes our system ideal for remodeling projects or any small new construction building including churches, schools, lodges, restaurants, nursing homes and more.
