Valves, drives and a specially designed elevator fan are now offered.
Hydraulic Lift Safety Valves
London-based Apex Lifts is offering gate lock valves in an effort to minimize cases in which technical faults have occurred and hydraulic lifts have descended with the doors open. The company states that in the unlikely event a valve fails or develops a significant leak, there is a risk the electrical re-leveling may be unable to cope, which can cause the lift to move with the doors open. The solenoid-operated product is available for any make or model of hydraulic lift. It works by de-energizing and closing when the lift arrives at floor level (when instructed to do so by the lift controller), ensuring the car stays put as passengers disembark and enter it.
UL-Listed, NEMA 4-Tested Elevator Fan
Man-D-Tec, Inc. has released what it calls “the first completely Underwriters Laboratories (UL)-listed, NEMA 4-tested elevator fan approved for hazardous locations.” The MVS®-HAZLOCTM single-speed, direct-drive exhaust fan utilizes an anti-static, spark-resistant, cast-aluminum fan blade to provide up to 925 CFM. A patent-pending service panel is removable for ease of wiring and maintenance. An explosion-proof handy box is supplied for wiring. It is designed for use in class-I, division-1 and group C and D, in addition to class-II, division-1, and group E, F and G locations.
New Drive Products from Magnetek
Magnetek, Inc. introduced its new Quattro® Cube AC Elevator Drive, HPV® 900 AF Elevator Drive, M1000 Elevator Drive and next-generation RegenAC™ Regenerative Braking Product at the National Association of Elevator Contractors exposition on September 8-11 in San Antonio, Texas. The Quattro Cube is an integrated regeneration drive including the same components as a full-sized Quattro, minus the full-size enclosure.
The HPV 900 AF drive is used to modernize a machine-room-less system. Featuring an axial flux permanent-magnet machine, the product is intended to be a practical, affordable solution for optimal elevator performance. Next is Magnetek’s newest drive, the M1000. It has been tested to provide more than 70,000 hr. of maintenance-free operation of induction and permanent motor applications. Finally, the high-performance RegenAC unit not only offers regenerative technology, but also higher current capacity for use with larger motors. It can be added to existing AC-drive installations for increased energy savings.
