The Ultimate Ride Quality Solution. For high-speed elevator cabins.
The Express-3 Roller Guide represents a groundbreaking combination of elevator ride quality, value, and ease of use.The culmination of a half-century of ELSCO expertise in improving ride quality, the 10-inch Express-3 utilizes a patented shock absorbing pivot bearing to isolate the elevator cabin and its occupants from uneven or misaligned rails. The result is a compact, light-weight roller guide that is the ideal choice for high-speed applications where low noise and a first-class ride are of the utmost importance.
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.
Innovative Elastomeric Bearingsincorporate bonded rubber at the pivot point of the wheel-arm assembly. This patent-pending component eliminates nearly all metal-to-metal contact between the arms and the base, effectively isolating the elevator cabin from the noise and vibration caused by uneven or misaligned rails. The bearing also acts as a torsional spring damper, resisting the pivoting action of the arm and dissipating energy.
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. 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.
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.
Independent Adjustable Stopsenable simple, precise control of the car’s overall float between the rails, in both postwise and front-to-back axes. Adjustable stops are a standard feature on the Express-3 guide.
