2:1 Elevator Counterweight Frame

The 2:1 elevator counterweight frame supports the counterweight elements with the relevant suspension arrangement. For selection, mounting dimensions and the corresponding mounting connections are assessed together against the current technical project drawings.

The images show the 2:1 frame, its filler arrangement and upper pulley from different angles. Crossmembers, guidance points and the pulley connection can be compared with the existing counterweight assembly during product assessment.

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 2:1 designation identifies the suspension arrangement to be considered. Rail spacing, frame dimensions, filler positions and pulley connections are examined together. Numerical values such as pulley diameter, rope groove dimensions and load capacity are verified in the selected frame's documentation rather than inferred from the images.

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.

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 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.
