Handrails for escalators and belt barriers
Ensuring comfort and safety for passengers moving along transportation routes is essential for the operation of mass transit systems. One of the most exposed visually and prone to wear components of any device are handrails for escalators. They provide users with a stable point of support, synchronizing their moving speed with the motion of the step belt. In our wholesale store for B2B industry, you will find professional and extremely durable handrails for escalators that guarantee flawless operation, excellent appearance, and full compliance with the regulations of the Office of Technical Inspection (UDT).
Handrails for escalators - FAQ
Professional handrails for escalators consist of several layers. The outer layer is usually made of wear-resistant and weather-resistant synthetic rubber (SBR) or polyurethane (PU). Inside the handrail, there is a load-bearing cord - usually steel or Kevlar - that prevents the belt from stretching under the stresses generated by the drive wheel.
The durability of a handrail belt depends on the intensity of passenger traffic and working conditions (inside/outside). In shopping malls, handrails for escalators are usually replaced every 5 to 8 years. Immediate replacement is required for belts that show deep transverse cracks, tears in the outer layer, exposed cord strands, or those that have undergone irreversible stretching.
To order the appropriate handrails for escalators, you need to provide their exact profile (e.g. C profile or V profile), total width, and extended length measured along the handrail axis. It is best to read this length from the technical-operating documentation (TOD) of the device or from the nameplate of the belt, as manually measuring the stretched rubber can lead to errors.
W przypadku drobnych uszkodzeń krawędzi lub wandalizmu (np. zarysowań) poręcze do schodów ruchomych niekiedy poddaje się powierzchownej regeneracji kosmetycznej. Jeśli jednak uszkodzenie narusza kord nośny, profil wewnętrzny ślizgu lub powoduje pęknięcia strukturalne, jedyną opcją zgodną z normami UDT jest bezwzględna wymiana lub wulkanizacja nowego pasa nośnego.
Najczęstszymi przyczynami degradacji są zjawiska zmęczeniowe materiału (wielokrotne przeginanie na kołach napędowych), starzenie się gumy pod wpływem promieniowania UV i środków czyszczących, a także usterki mechaniczne – takie jak zatarte rolki prowadzące poręcz, które powodują punktowe przegrzewanie się pasa i jego przyspieszone wycieranie.
Structure and Technology - What are escalator handrails made of?
A high-quality handrail is not just a piece of rubber, but a technologically advanced composite made up of multiple interconnected layers. Due to the immense tensile and bending forces generated on the drive and guide wheels, escalator handrails have a very specific structure:
- Sliding layer (inner) - directly interacting with the escalator's guide profile, usually finished with a special textile material (e.g., polyester cotton) that minimizes friction.
- Load-bearing cord - steel or kevlar reinforcing cables embedded inside the belt, responsible for preventing escalator handrails from elongating during years of use. Belt elongation leads to slippage on the drive wheel.
- Outer layer - an external grippy coating made of styrene-butadiene rubber (SBR), polyurethane (PU), or chloroprene (CR). It is resistant to wear, human sweat, UV radiation, and aggressive chemical agents used for cleaning facilities.
When are new escalator handrails a maintenance necessity?
From the perspective of UDT inspectors, the condition of the handrail has a decisive impact on allowing the device to operate. Worn-out or damaged elements pose a direct risk of hand injuries to passengers. As a maintenance technician, you must know that escalator handrails are subject to rigorous evaluation criteria. Replacement is mandatory when deep transverse cracks appear on the outer coating, exposing inner layers and reinforcement. Belts should also be replaced in cases of vandalism acts (e.g., deep cuts with a knife), edge deformations (C or V profile), and when the tensioner's adjustment range is exhausted - indicating critical and irreversible material elongation.
Compatibility and Selection - Leading Brands' Escalator Handrails
Every manufacturer of lifting equipment and escalators uses belts with different cross-sectional geometry profiles in their machines. Our wholesale specializes in providing O.E.M. quality replacements, meaning that our offered escalator handrails are 100% compatible with original drives. We supply belts designed for global brands such as Otis, Kone, Schindler, ThyssenKrupp (TK Elevator), and O&K. We deliver both open belt sections for vulcanization directly on-site (on the device) and factory-sealed loops for replacement after dismantling the balustrade.
We encourage engineers and service technicians to contact our advisors. Before placing an order, prepare the precise belt length, profile type (outer and inner sliding dimensions), and color. We will assist in selecting escalator handrails that will ensure the highest operational performance in the commercial or public utility building you service.
