Supporting Structure for Lifting Operations in Space-Limited Areas

A lifting auxiliary frame provides a structural foundation for lifting and material-handling operations where conventional cranes or fixed systems cannot be installed. It integrates with compatible hoists, winches, and lifting mechanisms to establish secure operational positions in restricted environments, such as building maintenance zones, narrow access routes, industrial workshops, and balcony openings.

FAQ

Q: What is a lifting auxiliary frame used for?

A: It provides an auxiliary structural support or lifting position for compatible lifting equipment, particularly where the installation environment limits the use of conventional lifting systems.

Q: Is a lifting auxiliary frame a hoist?

A: No. A frame is a structural component of the lifting arrangement. The actual lifting function is provided by a compatible hoist, winch, or other lifting mechanism.

Q: Can the frame be used indoors?

A: Yes. Indoor lifting applications in space-restricted areas are among the primary use cases for compact auxiliary lifting frames.

Q: Can a lifting auxiliary frame be customized?

A: Yes. Dimensions, mounting configurations, lifting point positions, arm reaches, and adjustment ranges (+/-, deg) can be adapted to specific project requirements through technical drawings.

Q: How do I choose the correct frame?

A: Start with the required working load (>=) and installation conditions, then evaluate available space, support structures, lifting equipment compatibility, and adjustment ranges.

Q: What information should I provide when requesting a quotation?

A: Provide the required working load, installation dimensions, lifting equipment type, working height or reach, mounting conditions, quantity (%), and any available sketches or photographs.

Q: Does the frame require load testing?

A: Testing requirements depend on the product design, application, applicable regulations, and customer specifications, which should be agreed upon before production.
