FAQs

What is a hydraulic elevator?
Hydraulic elevators feature a piston at the bottom of the elevator that uses oil or other hydraulic fluid to control the lift or descent of the elevator. Hydraulic elevators are typically used for low-rise applications of 2-8 stories and can travel at a maximum speed of about 200 feet per minute. The machine room for hydraulic elevators is typically located at the lowest level adjacent to the elevator shaft.

Hydraulic elevators typically have a lower initial cost, and lower ongoing maintenance costs than other elevator types, but use more energy and can be susceptible to hydraulic fluid leaks, a potential environmental hazard.  For these reasons, hydraulic elevators are not installed as often as in the past.

What is a traction elevator?
Traction elevators feature an electric motor in a room typically located above the elevator shaft, and are lifted by ropes that pass over a sheave attached to the motor.  Traction elevators are used for mid- and high-rise buildings and offer faster travel speeds than hydraulic elevators.  A counter weight is used to offset the weight of the car and occupants, making the elevator more efficient. Geared traction elevators, traveling at up to 500 feet per minute, are best suited for mid-rise applications. Gearless traction elevators can travel up to 2,000 feet per minute, with a maximum travel distance of around 2,000 feet, making them the only choice for high-rise applications.

What is a Machine Room-Less (MRL) elevator?
An MRL (Machine Room-Less) elevator is a type of electric traction elevator that does not require a separate machine room. Instead, the MRL is designed to house the machine in the overhead area at the top of the elevator shaft, with control equipment located in a small adjacent room within about 150 feet of the machine. MRL elevators are typically less expensive than traction elevators, and more expensive than hydraulic elevators. There are advantages and disadvantages to the design of an MRL elevator vs. traction and hydraulic elevators. Talk to your Specialized Elevator representative for detailed information.

Does Specialized Elevator service all types of elevators?
As an independent elevator service company, Specialized Elevator provides repair and maintenance service for all makes and models of elevators.  Please contact us to inquire about your specific equipment.

Does Specialized Elevator install proprietary elevator equipment?
No. Unlike the large elevator companies, Specialized Elevator uses non-proprietary elevator equipment that can be serviced by most trained elevator service and repair personnel. Our approach to installing non-proprietary equipment helps keep installation and maintenance costs lower, while ensuring the ready availability of qualified repair and service personnel.

Am I required by law to have an elevator service contract?
The ASME A17.1 requires all elevators to be maintained by qualified elevator personnel. If the 2010 version of the code (or later) is applicable in your jurisdiction, you are also required to have a Maintenance Control Plan (MCP) for your equipment at all times.

What is a Maintenance Control Plan (MCP)?
A Maintenance Control Plan (outlined in Section 8 of the ASME A17.1 code) is a program that covers general requirements for elevator maintenance and record keeping. The MCP includes all information needed to maintain, service, and repair the elevator equipment, and must be accessible on-site at all times to elevator maintenance and service personnel.

I received a preliminary order from the state.  What do I do?
Notify your elevator service provider and send them a copy of the Preliminary Order.  They will be able to assist you in getting the items cleared.  Some items may be the responsibility of the conveyance owner to correct.

Where can I find information on elevator inspections as required under California law?
Information on elevator inspections in the State of California can be found at https://www.dir.ca.gov/dosh/ElevatorFaq.html. Or contact your Specialized Elevator representative to learn more.
