4:1 Elevator Counterweight Frame

The 4:1 elevator counterweight frame supports the counterweight group with its suspension and guidance arrangement. Existing mounting dimensions and the corresponding mounting connections are assessed together against the current technical project drawings.

The 4:1 frame is shown with a wide supporting structure and upper connection arrangement. Its visible geometry is compared with the existing counterweight installation, while exact technical values are obtained from the selected model documentation.

Application and Product Selection

The counterweight frame retains the filler elements and brings together the suspension and guidance connections. Modernisation examines the existing weight arrangement, shaft position, rail spacing and clearances to adjacent equipment. Selection is based on a project that defines the counterweight assembly's relationship with the car and drive, including access for mounting and later inspection.

The 4:1 arrangement is assessed together with the rope route and pulley connections. Frame height, width, filler retention and rail relationships are compared with the other project components. A 2:1 frame is not treated as a direct substitute; the selected suspension layout requires its own technical compatibility assessment.

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 and commissioning checks should be carried out by qualified personnel in accordance with the product instructions and the technical requirements of the project.

The inspection plan covers filler retention, crossmembers, uprights and guidance connections. Suspension and any pulley connections are examined for the selected model. Loosening, corrosion, wear or changes in position are recorded. Work on the frame follows the product instructions while maintaining its relationship with the complete counterweight assembly and associated installation components.

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. For traceable product selection, record the measurement date, installation position, component name and revision of the technical drawing used to compare the existing assembly with the selected configuration.

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.
