Installing
a home elevator is a home improvement like remodeling. any major decision
to upgrade your home should be dome with a thorough understanding of elevator
construction, codes, issues and terminology.

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.
