What information is needed to select progressive elevator safety gear?
Provide the mass to be arrested, rated and tripping speeds, guide-rail specification, rail surface condition and installation geometry. Include the actuation arrangement and intended direction of protection. Selection must be checked against the exact safety gear documentation and the elevator design.
What is the intended application of Counter Weight?
Counter Weight is grouped for the elevator or escalator function represented by the listed product options. Confirm the exact model and application before selection.
What is the intended application of INVT?
INVT is grouped for the elevator or escalator function represented by the listed product options. Confirm the exact model and application before selection.
What is the difference between an elevator landing lantern and a floor indicator?
A landing lantern signals direction or arrival, while a floor indicator displays car position. Some assemblies combine these functions. Specify which information passengers need and how the controller provides it before selecting a replacement or new landing indicator.
How do I match an INVT elevator car operation board to my controller?
Provide the complete board code, revision, controller series and software information. Include connector photos and the COP wiring diagram. Confirm the supported board-controller combination before purchase, since a shared INVT brand name does not establish compatibility.
What is the intended application of Light Curtain?
Light Curtain is grouped for the elevator or escalator function represented by the listed product options. Confirm the exact model and application before selection.
What is included in a complete elevator traction system?
Agree the scope for machine, sheaves, ropes, terminations and machine supports. Identify the drive and brake control interfaces even if they are supplied separately.
How do I identify replacement plugs and pins for an elevator control cabinet?
Record connector series, pole count, pitch, keying, latch style and contact markings. Photograph both mating halves and the connected board or terminal. A connector that appears to fit may have different contact dimensions or ratings, so confirm the exact mating system.
