LU/LA stands for Limited Use/Limited Application. The LU/LA elevator is basically a small commercial elevator. The controls momentary pressure, not continuous pressure like a wheelchair lift. The entrances are normally two speed automatic sliding doors just like a full commercial elevator. The ‘limitations’ are 25’ of travel; 30 fpm; 1400lb capacity and 18 sq. ft. of floor space.
The benefit of the LU/LA elevator over a full commercial elevator is the space and cost savings. Overtravel and pit depth are much less than a full commercial elevator saving construction costs of a deep pit or roof penetration. You also save floor space and power consumption.
The benefit of the LU/LA elevator over a vertical wheelchair lift is the increased capacity. If you need a heavy duty accessibility solution that everyone can use, not just the mobility impaired, then the LU/LA may be the answer.
LU/LA elevators are often used in schools, libraries, small commercial buildings, and churches as an alternative to a full commercial elevator. In most jurisdications the LU/LA does not have the restrictions for use in new construction that limit vertical and inclined platform lifts.
LU/LA Elevators come in five main styles. To determine which style is right for your application, see Tech Specs.
Pit and Car Top Prop
You can reduce pit depth and over travel substantially because in ASME A17.1 the safety standard for elevator, there is an exception to the requirements for the LU/LA. If you provide a device that a mechanic can set without bodily entering the hoistway that will mechanically stop the elevator creating refuge space you do not need to meet the full pit and over travel requirements.
High Performance Entrances
Typical LU/LA packages include commercial elevator grade two speed (two panels move- reducing hoistway width requirements) sliding entrances with a power door operator on the roof of the cab. This gives the user the look and feel of a full commercial elevator.
ADA Hands Free Phone
This is a requirement in most jurisdictions and can be built into the control operating panel just like on a commercial elevator.
LU/LA elevators can hold up to 1400lbs, but cost significantly less than commercial elevators. They can handle frequent use due to the heavy duty design of the drive system and the drive does not require a bore hole to be located under the car. Instead, the drive sits alongside the car pushing up a sheave that uses cables attached to the car and the base of the support system to move the car 2″ for every inch the piston extends.
Fixtures including call stations, car operating panel, and handrail can be Stainless or Brass in a #4 brushed finish or polished as well as other customized finishes.
