The next level in ride quality
- ULTIMATE RIDE QUALITY
- MINIMIZED NOISE & VIBRATION
- TAKE CONTROL OF FLOAT
- DURABLE, ENGINEERED DESIGN
Product Description
The Express-3 provides first-class ride quality in very high-speed applications where it’s needed most. Patented vibration-suppressing pivot bushings and 10” (254 mm) neoprene roller wheels isolate the elevator cabin from unsettling noise and vibration.
Designed for elevator cars up to 2,000 fpm (10 m/s) or 5,000 lbs (2,300 kg) capacity in high-rise buildings, the Express-3 is a high-speed three-wheel roller guide with spring suspension, adjustable stops in all directions, and three premium 10” (254 mm)diameter neoprene rollers.
Engineered and tested to meet ASME A17.1/CSA B44 and EN81 standards, ELSCO’s Express-3 roller guide is constructed from precision machined aluminum and ductile iron castings and is assembled using quality parts to ensure your elevator ride will GO UNNOTICED.
-
Ten-Inch Roller Wheels
- Extra large diameter rollers reduce wheel RPMs at high speeds resulting in a smoother, quieter ride
- Help deal with hoistway imperfections that can be especially troublesome in high-rise buildings
-
Patented Elastomeric Pivot Bushings
- Provide additional suppression of vibrations, more prevalent in higher speed applications, resulting in improved passenger comfort and tenant satisfaction
-
Neoprene Rubber Rollers
- Precision manufactured using ELSCO’s proprietary neoprene rubber tread compound
- 65A durometer tread dampens vibration and reduces noise
- Precisely ground tread profile provides a balanced and concentric roller
- High-memory tread characteristics prevent flat spotting
- Excellent resistance to oils, chemicals and UV for extended life
-
Precision Ball Bearings
- Industrial grade, high quality ball bearings will last for millions of cycles
- Dual bearing design provides the roller wheel extra stability to ensure a true ride, free of noise and vibration
- Precision bearing press process during assembly at ELSCO ensures perfect fit, alignment and quality
-
Fully Adjustable Stabilizing Springs
- Independently adjust the pre-load force of the rollers on the rail to minimize bumps and vibration
- Allow for maximum adjustability to optimize reduction in peak-to-peak horizontal forces which improves ride quality
-
Adjustable Stops
- Allow independent control of the overall float of the elevator car between the rails in post-to-post and front-to-back directions
- Allow for precision final adjustments to deal with troublesome hoistway issues that adversely affect ride quality
-
Robust Components
- Precisely machined castings ensure the final assembly is of the highest quality
- Tested to meet applicable codes and standards ensuring the guides provide a lifetime of reliable performance
