A workhorse solution for high-rise or heavy service loading elevators
The Model A Roller Guide has been the elevator industry’s gold standard for elevator ride quality for more than 45 years. Its outstanding performance, rugged durability, and extended application range make it our flagship product. Model A roller guides are designed with a number of features that provide superior riding characteristics. Spring-dampening in all directions and our unique “walking beam” design compensate for adverse operating conditions, bumps, and vibration. Simple adjustment procedures allow for customization to the specific challenges of the installation.
Six-Wheel Designimproves ride quality and extends the application range. The tandem roller design allows the guide to “step over” misaligned rail joints with only minimal disturbance to the cab and its occupants. And by using six rollers where most other guides use just three, the Model A can withstand the higher loads associated with service and hospital cars. The added stability also helps compensate for unbalanced conditions.
Neoprene Rubber Roller Wheelsare specially compounded and rigorously tested to ensure a smooth, silent ride. Only genuine ELSCO neoprene wheels provide the damping characteristics essential to ride quality, and only genuine ELSCO wheels are engineered with high memory characteristics that prevent flat spots. ELSCO rollers are precision ground to within .002 inches (50.8µm) Total Indicator Reading for perfect roundness and concentrically, then 100% inspected under stress to ensure bond between tire and hub.
Adjustable Stopsenable precise control of the car’s overall post wise float between the rails. Adjustable stops are a standard feature on the Model A guide.
Fully Adjustable Dampening Springsallow the car to float between the rails, eliminating the bumps and vibrations that adversely affect ride quality.
Precision Ball Bearingsguarantee years of silent use. ELSCO specifies bearings intended for the high RPMs and demanding loads of electric motors - conditions far more rigorous than typically seen in elevator applications. This means that even after years of operation and tens of millions of cycles, only ELSCO roller wheels remain completely silent. Each bearing bore is machined to a tolerance of five ten-thousandths (.0005) of an inch (.127mm), and two bearings are pressed into each wheel by a computer-driven press, ensuring perfect fit and alignment.
Durable Structural ComponentsELSCO castings are made from high tensile-strength ductile iron and aluminum for an optimal combination of strength, durability, and light weight. High quality guide hardware ensures long life and ease of adjustment in the field. All components are inspected and assembled to exacting standards for a lifetime of reliable performance.
