ON-05 Elevator Landing Door Retiring Cam

ON-05 is an electromechanical retiring cam for the elevator landing door unlocking arrangement. Assess its mounting base, operating lever and interaction with the lock according to the layout of the existing door system.

The ON-05 image highlights an elongated mounting base and its own lever geometry. If replacement with ON-01 is being considered, compare fixing points and the operating path individually.

Application and Product Selection

A retiring cam is a door system component that interacts with the unlocking mechanism of the elevator landing door lock. For modernization, review its relationship with the existing lock, direction of movement and installation position together. Body placement and lever geometry must suit the position of the interacting components. Selection should not rely solely on resemblance to the existing unit.

Compare mounting base dimensions, fixing points, the operating path of the lever and alignment with the locking mechanism. Verify supply voltage, electrical connections, duty requirements and unlocking movement against current product documentation. ON-01 and ON-05 are distinct model codes; their similar purpose does not mean that all dimensions and connections are identical.

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.

During maintenance, assess free movement of the operating elements, fixing condition, cable routing and interaction with the lock. Review adjustments together with the existing door mechanism and follow the product instructions. After replacement, verify the retiring cam movement and its relationship with the door lock within the commissioning control plan for the relevant system.

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.
