ONAG-01 Elevator Governor Tension Pulley

ONAG-01 is a tension pulley model for the elevator overspeed governor rope arrangement. Review the pulley position, supporting fixings and rope path together with the existing governor system when assessing compatibility.

The ONAG-01 image shows the pulley together with its supporting connection plate. Rope alignment, mounting space and maintenance access are key assessment points for selecting this model.

Application and Product Selection

A tension pulley is a separate component within the tensioning arrangement of the overspeed governor rope. It should not be treated as a replacement for the governor itself. Modernization planning considers the pulley location, rope path, supporting structure and maintenance access together. Selection should preserve the integrity of the existing governor and rope arrangement.

Compare pulley dimensions, rope groove geometry, supporting fixings and available mounting space with the existing component. Verify the suitable rope diameter, tensioning arrangement and any monitoring features against technical documentation. The mechanism shown in the photograph is not sufficient to determine numerical values for weight, tensioning force or electrical characteristics.

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.

The maintenance plan should cover pulley rotation, interaction with the rope, supporting fixings and obstructions within the movement area. Assess signs of wear, misalignment or loose fixings according to the relevant maintenance instructions. Checking all components that work with the governor rope requires a broader assessment than the appearance of the tension pulley alone.

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.
