The UNITEC Track and Hangers Modernization Package is a new package specifically designed for retrofitting existing tracks and hangers. The new package has been designed with much more flexibility than traditional tracks and hangers, so the equipment will fit into existing site conditions much more easily.
Door operation is the first thing passengers experience when they ride an elevator, and by conveying that the elevator is a reliable, safe, high-quality system, their confidence will increase. UNITEC's Tracks and Hangers provide smooth and quiet door operation, improving reliability by using the highest-quality rollers, cables, door locks and other material in a flexible, straightforward product design.
UNITEC provides very robust track and hanger sets for all sorts of Door Modernization jobs as well as Entrance additions or rust outs. The drawings are provided here for reference for both the CAR & HALL side and for opening types: S/S, C/O & 2-Speed. Most installers are concerned with adapting to existing door tops and existing headers. No one wants to drill if they can help it. So UNITEC in offering these excellent and flexible sets, carries hanger options having various bolt spacing to adapt to both Otis and Non-Otis door tops. Hanger bolt spacing designs which have been manufactured for past jobs (not necessarily all stocked) include the most common for Otis which is 4-5/8”, but also: 4”, 4-1/8”, 3-1/4”, 3-3/4”, 4-1/4”, 4-3/4”, 5”. And the holes/slots can be suited for 3/8” or ½” bolts. You must allow ample lead time for any special hangers to be manufactured. However, you can be assured that we very commonly stock The 4-5/8”, 4-1/8” & 4” bolt spacing door hangers. In addition, do not get hung up on adapting to the header. If it is easy enough to remove the old, why not consider ordering new headers from UNITEC. (see our ‘Otis Integral Header Service Upgrade Solution’ page below). This is especially the case if either you already have Otis 6940 locks, or will be installing Otis 6940 locks. The headers are set up for this equipment. We will stock a number of typical headers, for the typical Otis opening sizes. Headers come pre-punched for the standard size openings (36”, 42”, 48”, 54”). And, these header kits are unhanded so no worrying about correct hand. When applying new UNITEC track and hanger sets, avoid the labor Time and drill bit cost of drilling and applying nutserts/rivnuts. New headers is a no-brainer when any rust is present, or if you want to save the labor.
