Codes
The national safety code that applies to residential elevators is ASME/ANSI A17.1 Part V, Private Residential Elevators. Our elevators are designed to meet national and local safety codes.

Electrical Issues
top

Please double check below highlighted areas. HEI provides all low voltage wiring for door interlocks, call buttons and control wires. An electrical contractor must provide main power for elevator: 220 volts 1 PAASE 30 AMPs and 110 volts 1 Phase 15 AMPs. HEI can select or recommend a reputable electrical contractor.


Elevator and Hoistway Doors
top

Elevator doors are a big consideration. Doors can conceal the elevator (put behind a manual swing door that matches other doors in the house), or they can become a featured focal point in the house. HEI can help you find the perfect elevator doors for your home. Elevators have two doors: one for the car (interior, called the car gate) and one for the hoistway (exterior). Following are four possible combinations:1) a manual folding accordion gate as the car door and a manual swing door for the hoistway.2) a manual folding scissors gate as the car door and a manual swing door for the hoistway.3) an automatic bi-fold car door combined with manual swing hoistway doors.4) semi-automatic sliding car and hoistway doors.

Elevator Terminology
top

Car - Cab, or finished portion of the elevator in which people ride.Car Gate - Door or gate that is connected to the car and travels with the car.

Electromechanical Interlocks - Electrically and mechanically wired lock in the door that prevents the door from opening when the elevator is not stopped at the landing. *Our elevators will not run unless all doors are closed and latched.

Hoistway - Also called the shaftway, the opening created in a building through which an elevator passes.

Hoistway Door - Door opening to hoistway at a landing.

Home Elevator - A home (or residential) elevator is an elevator primarily designed for the needs of private residences and multi-family housing such as townhomes and condominiums. Jack (Hydraulic) - A unit consisting of a cylinder equipped with a plunger or piston which applies the energy provided by a liquid under pressure.

Machine Room - A room constructed adjacent to the elevator hoistway to accommodate the drive system and electrical control box.

Overhead Clearance - The clearance needed to accommodate the components on top of an elevator car. It is measured from the upper level floor to the lowest obstruction at the top of the hoistway. * A minimum of 8 feet is required.

Pit - The recessed portion of a hoistway extending from sill level of lowest landing to the floor at the bottom of the hoistway. * A minimum of 6 inches required.

Rail - The metal track that guides the elevator in a vertical path. Residential Elevator - A residential (see home elevator) elevator is an elevator primarily designed for the needs of private homes and multi-family housing such as townhomes and condominiums.

Sheave - A pulley.

Winding Drum - A geared drive machine on which suspension ropes are fastened and wind on a rotating drum.


Hoistway Construction

top

After selecting a model, the next step is to survey and select the space in the home for the elevator and hoistway (shaft).The hoistway must be built to specification from drawings HEI creates prior to construction.The walls of the hoistway must be plumb and square, and meet the structural requirements outlined in the elevator planning guide.

Machine Rooms
top

A machine room adjacent to the hoistway will be required to accommodate the elevator drive and control system. The machine room must have a self-closing, self-locking, keyed door. Minimum machine room size is 36"x48".The best orientation for a machine room is on the same side of the hoistway as the elevators rails. Other orientations are possible, but require allowances for pulling the wire ropes or hydraulic lines around corners.A machine room may also be located above (in an attic) or below (basement) or in a crawlspace. Likewise, allowances must be made for accommodating wire ropes or hydraulic lines. Consult Home Elevators, Inc. for specifics concerning non-standard machine room placement.** JIM WROTE: light, phone jack GRII - not sure where that goes or how to integrate it into text.

Overhead Clearance
top

Elevators require a certain amount of overhead clearance to accommodate essential components on top of the car. Overhead clearance is measured from the upper level floor to the lowest obstruction in the top of the hoistway. *A minimum of 8 feet is needed for a standard 80 inch elevator car.

Pit Construction
top

The pit is the space at the bottom of the hoistway that is below the bottom landing level to accommodate the necessary support structure of the elevator system and hoisting mechanism. A minimum of 6 inches is required for a winding drum mechanism and 12 inches is required for a roped hydrolic system. The pit floor must be flat, smooth and level and a minimum of 4 inch thickness. Make sure you allow for the pit when pouring the foundation.
