What Are Your Escalator Handrails
Telling You?
Ensure the safety of the riding public and the longevity of escalator handrails by watching
for these telltale signs.
by Patrick Bothwell
As with any wear item, handrail service life will vary greatly
depending on passenger loading, surrounding environment and
alignment. Inspections required by code are focused on
ensuring the safety of the riding public, rather than service
longevity or value for the building owner. These need not be
mutually exclusive. Regular handrail inspection will not only
keep the inspectors smiling, but, with a little interpretation, it
can save money in the long run and virtually eliminate the need
to expedite replacements. We will explore a number of the
more common signs of impending handrail trouble, identify the
problem and look at possible courses of action.
time to schedule a handrail replacement before the bulges get
to the size where they will trip the handrail entry switch. The
good news for those who have NT thermoplastic handrails
(ELEVATOR WORLD, December 2011) is that they will never
delaminate.
Cracked Lips?
Cracks in the handrail lip area can pose a real pinching
hazard and should be dealt with immediately. While lip cracks
Continued
Old and Wrinkled?
The rubber handrail surface will start to wrinkle and crack
with age and exposure to the elements. Over time, typically
seven to 10 years, the protective ingredients in the handrail
cover will be reduced, and, much like our skin, will start to
show its age. Aging can happen prematurely in aggressive
environments with high ultraviolet light or ozone present.
Cleaning or sanitizing with aggressive solvents or other
compounds will also take years off a handrail’s life. Use only
mild cleaning agents, preferably those designed for escalator
handrails. Rubber handrails can benefit from regular
application of rubber protectant.
Bubbles and Bulges?
Small bubbles, eventually forming into larger bulges,
indicate that the internal layers of the rubber handrail carcass
have delaminated. These layers of rubberized fabric have come
apart, leaving a pocket of broken-down rubber fragments and
air. When found within the first few weeks of operation,
delamination can be the result of a handrail-manufacturing
defect, but it is more commonly caused by excessive drive
pressure. If identified quickly, handrail setup can often be
adjusted to stop the delamination process from continuing,
and, on newer handrails, repairs can be possible. On older
handrails, bubbles and bulges are a good indication that it is

Optimal handrail tension lies somewhere in between and
will vary with different escalator models. A handrail
temperature of more than 5°C above ambient is a good
indication that tension is still in need of adjustment.
Dust Buildup and Frayed Fabric?
During the course of a handrail’s initial running-in
period, some dusting is to be expected. This is completely
normal, but excessive dust buildup is not. At the first sign
of excessive dusting, the handrail should be removed, and
the layer of sliding fabric should be inspected for irregular
wear patterns. Debris should be removed from the drive
path. More often than not, the wear pattern will give clues
as to where to look to remedy the issue before it leads to
irreparable handrail damage.
Conclusion
In the case of a shut-down escalator — either due to
breakdown or code-violation handrail replacement —
decisions are made in haste, with priority given to getting
the unit back into service. Too often, especially with
full-maintenance contracts, the choice is made to replace a
handrail using the lowest-cost option, often to the
detriment of a long and trouble-free service life. Taking the
time to piece together the handrail’s story is a sure way to
reduce costs associated with having to expedite shipment
of replacement parts when a unit is shut down.

The New ECS
EHC Global
The New ECS Corporation, under new ownership is making a major impact in the elevator
and escalator industry. Strategic personnel additions and key organizational and operational
changes have clearly made the New ECS a key
supplier to the industry.
The company has continued to revamp and
improve its operation with a variety of investments from people, to inventory, to systems, and
equipment. The most recent investment is a high
powered conveyer washer that improves the
power washing, the completion time for step refurbishment, and is much more energy efficient.
Centrally located in the Chicago area, ECS
can deliver products to almost any location in
North America quickly. Along with the incredibly
efficient refurbishment program, a new roller
production facility, a new robotic welder, a new
blasting machine, brand new steps, arguably the
widest selection of step chains in the industry,
an additional facility that now houses a 70%
increase in inventory levels, and onsite support
visits, the New ECS is quickly becoming the first
choice among service providers for parts and
solutions.

Of all the equipment in a building, vertical
transportation is the one and only mechanical/
electrical systems with which building occupants routinely have direct, physical contact.
For a building to be a successful venture, in
addition to providing a pleasant environment
for occupants, its mechanical and electrical systems must provide safe and reliable
service – particularly with respect to vertical
transportation. While the primary responsibility for maintaining the vertical transportation
systems rests with the maintenance specialists
and contractors, there are many aspects of
which owners and managers must be aware.
This manual has been developed to explore
the responsibilities of building owners and
managers, as well as maintenance providers, in
an effort to provide guidance in establishing
an adequate maintenance program that will
be a long-term benefit to building occupants
and the equipment that serves them. This
book will also assist building managers in
making informed decisions regarding upkeep
and regular maintenance of elevators and
escalators under their control.

The Tolar Impact Tool is a dual-purpose
product used to verify the stationary loaded gap
test as noted in ASME A17.2, 7.17.2 (b) (1)-(8) and
the comb-plate impact test A17.2, 7.7.2. The tool
checks both the vertical and horizontal forces for
setting comb and skirt switches. It also checks
distance at proper pressure to the step from the
skirt. It has a digital readout and is all aluminum
enclosed in a Pelican™ brand impact-resistant
case with load cells that can be removed for
annual calibration. The tool has an attachment
that will allow the test to be performed under
escalator skirt brushes so that the removal of the
brushes is not necessary.
The product was developed by Dale Tolar of
Dale Tolar & Associates Inc. in Fort Worth, Texas.
The 57-year veteran of the elevator industry was
inspecting a group of 50 new escalators at a new
Dallas/Fort Worth International Airport terminal
several years ago with a skirt and comb impact
tool he found rudimentary and inaccurate. This
prompted Tolar and his son (a modernization
superintendent for a major company) to begin
development of a better tool intended to not
only rectify the problems they found in the
existing tool, but also be cost effective, simple to
use, robust and accurate.
Tolar has been a QEI since 1989 and worked
with ESCO and Otis. He owned Tarrant Elevator
Service of Fort Worth for several years before
selling it to Dover and becoming a full-time
inspector, first for Fort Worth and then for Texas,
for which he currently inspects.
