•
W inding drum
A motor located at the top of the hoistway pulls

•
O ne side of the c hain or c able is connected to the
elevator sling assembly and the other end is
attached to a s tack of weights.
•
T he s tack of weights, off-set the weight of the
elevator cab which c auses less work for the motor.

Bas ically gravity does most of the work and the
motor jus t transfers weight back and forth.

The Future of Residential Elevators
“A fter examining our M aple L awn c lients’ demographics, we identified
that we c ould grow the market for four- level town home-style
c ondominiums by including private elevators inside each home.”
Thomas A. Baum,
President - Bozzuto Homes
“A s an as sistive technology, home elevators add value to a home. A
s uc cessful home is built to last ac ross multiple generations and to
s ervice the s uccessful use by multiple generations with minimal to no
alterations.”
Sean Vance,
Extension Assist. Professor & Director NCSU Center for Universal
Design - NC State University
55

14
The Future cont’d
“G iven the vas t numbers of the c urrent generation of aging baby
boomers , it is c lear that the demand for res idential elevators will
c ontinue to grow. M any older adults are planning to remain in their
homes as they age. Renovation to fac ilitate “aging-in-place” is
bec oming muc h more c ommon – inc luding the us e of res idential
elevators to provide a s afe and c onvenient means of moving between
levels.”
