For the most challenging speed and loading requirements.
The Express-6 Roller Guide is the ultimate solution for the most demanding elevator applications. Engineered for use on elevatorsthat “push the envelope,” the rugged design and heavy construction of the Express-6 make it ideal for the very fastest elevators, and those with extremely challenging loads.
The Express-6 is typically used on very high-capacity, very high-speed cars, such as observation shuttles in very tall buildings. Its striking size and design have also made it an architectural element in more conventional elevator installations with exposed hoistways.
Six-Wheel Constructionimproves 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 wheels where most other guides use just three, the Express-6 can withstand the higher loads associated with service and hospital cars. The added stability also helps compensate for unbalanced conditions.
Ten-Inch Roller Wheelsspread impacts over a larger area of the wheel arc, providing a smoother, quieter ride. The large wheel also reduces RPM, reducing the possibility of bearing noise and lengthening wheel life.
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 (,051mm) “Total Indicator Reading” for perfect roundness and concentricity, then 100% inspected under stress to ensure a secure bond between tire and hub.
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 (,0127mm), and two bearings are pressed into each wheel by a computer-driven press, ensuring perfect fit and alignment.
Fully Adjustable Stabilizing Springsallow the car to float between the rails, eliminating the bumps and vibrations that adversely affect ride quality.
Adjustable Stopsenable precise control of the car’s overall postwise float between the rails. Adjustable stops are a standard feature on the Express-6 guide.
Durable Structural ComponentsELSCO castings are made from hightensile-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.”
