How do I identify the correct elevator landing door lock replacement?
Record the complete lock code, handing, mounting pattern, hook geometry and electrical contact arrangement. Include photos of the lock in its installed position and the door mechanism label. A similar-looking hook or housing does not establish correct locking engagement or circuit suitability.
What is the intended application of Car Door Mechanism?
Car Door Mechanism 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 Diverting Pulleys?
Diverting Pulleys is grouped for the elevator or escalator function represented by the listed product options. Confirm the exact model and application before selection.
How do I choose an elevator car door operator for a modernization?
Provide opening width and height, panel arrangement, door mass, available header space and the landing-door coupling details. Include the controller interface and existing drawings. The operator must be evaluated with the complete door system rather than selected only by opening width.
What is the difference between a car door operator and a complete lift door system?
The operator drives the car doors. A complete system also needs coordinated panels, landing equipment, coupling, locks and protection interfaces as specified.
How do I choose a replacement elevator door light curtain?
Identify the existing transmitter and receiver, supply, output interface, mounting arrangement and cable routing. Check the door controller's input requirements. A light curtain that fits the door height may still be electrically incompatible or unsuitable for the required door-protection function.
What is included in an elevator cabin decoration package?
Define wall finishes, ceiling, floor, handrails and trims in the bill of materials. Clarify whether lighting and operating panels are included.
How do I select an elevator overspeed governor replacement?
Provide the governor model, rated and tripping speeds, rope specification, mounting arrangement and safety-gear requirements. Identify the protected direction and any remote functions. The replacement must match the approved safety system, rather than just the pulley size.
