ONPT-01 Polyurethane Elevator Buffer

ONPT-01 is a polyurethane buffer model for elevator pit buffer applications. Its body form, installation space and compatibility with the existing system should be reviewed together when selecting a variant for maintenance or modernization.

The ONPT-01 image shows a cylindrical body with a central opening. Comparing the body dimensions with the available installation space is as important as selecting the model code.

Application and Product Selection

Polyurethane buffers are elevator safety components used in pit buffer arrangements. Application on the car or counterweight side, the existing layout and project requirements influence product selection. Review the buffer position, contact arrangement and surrounding clearances together when planning replacement. The role of the component within the system matters alongside its physical form.

Compare body height, diameter, fixing arrangement and mounting surface during selection. Permitted operating speed, load range, working travel and performance information must come from current manufacturer documentation. Different body forms shown in images should not be assumed to have the same technical capacity. Verify the order code together with the intended operating conditions.

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 assessment should cover the body surface, cracks, permanent deformation, displacement and the integrity of the fixing area. Check suitability for exposure to oil, chemicals or environmental conditions against product care instructions. A replacement decision should consider the elevator maintenance records, operating conditions and manufacturer assessment criteria, rather than appearance 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.
