ONA-02 Elevator Door Damper

ONA-02 is a damper model for elevator door mechanisms. Compare the body, operating lever and mounting connections with the existing door arrangement to select a suitable product for maintenance or replacement.

The ONA-02 body and lever connection arrangement are identified through its own image. If replacement with ONA-01 is considered, compare hole positions, mounting direction and operating path individually.

Application and Product Selection

A door damper is a door system component that works with the movement arrangement of the relevant door mechanism. For modernization, review the body position on the door, the motion transmission lever and interacting parts together. Models within the same product group may have different fixing and lever forms. Consider the model code, existing mounting space and door operating geometry together during selection.

Compare body length, fixing holes, lever path, mounting direction and the needs of the existing door mechanism. Verify movement characteristics, adjustment options and operating conditions against current product documentation. A photograph does not establish exact force, stroke or door weight values. The similar purpose of ONA-01 and ONA-02 does not mean all their connections are interchangeable.

A product should not be selected solely from a photograph or a similar model name. Exact dimensions, connection arrangements, operating conditions and system compatibility should be assessed against current technical documentation. Images show the general product form and do not replace a scaled manufacturing drawing. Check the application requirements together with the variant to be ordered.

Installation Planning and Maintenance

Before replacement, record the position of the existing component, its fixing points, interacting parts and maintenance access. Installation planning should cover dimensional comparison, suitable fasteners and the way components operate together. Installation and commissioning checks should be carried out by qualified personnel in accordance with the product instructions and the technical requirements of the project.

Maintenance should assess moving elements, fixing security, body condition and any signs of leakage or irregular motion. Carry out adjustments and functional checks together with the existing door mechanism according to product instructions. After replacement, check the damper operating path and relationship with other parts. Record application settings in maintenance documentation to provide a reference for subsequent assessments.

Keep the product code, selected variant, quantity, installation position and technical documents in the project file for maintenance and future sourcing. Reference photographs and dimensional records of the replaced component can also be included. This provides a traceable basis for selecting components for subsequent modernization work on other elevators with the same arrangement.

Modernization Project and Quotation

When requesting a product assessment or quotation from Katrelift, share the model code, required quantity, a photograph of the existing component and the relevant fixing dimensions. Indicating whether the project concerns a new installation, maintenance or modernization helps identify the appropriate variant and the associated components that should be considered together.
