Say Goodbye to Hassle! JINPAT Slip Rings—Engineered Specifically for Cranes

Traditional slip rings typically come with lengthy lead wire harnesses, which often lead to issues such as tangled cables and wiring confusion during the on-site assembly of cranes. Through bold structural innovation, JINPAT through-hole slip rings precisely resolve this critical user pain point.

I. Flexible "Lead-Free" Structure

Unlike traditional products, this slip ring features a unique structural design in which neither the rotor end nor the stator end is equipped with external lead wires:

• Screw Terminal Connection: The internal conductive rings are routed directly to a terminal block; users can quickly complete cable connections simply by tightening the screws.

•  Integrated Junction Box: This design allows users to perform wiring operations directly within the slip ring's built-in junction box. This not only ensures a neat and aesthetically pleasing appearance but also significantly enhances the electrical safety of the wiring connections.

II. Exceptional On-Site Adaptability

Given the wide variety of crane models and the diverse requirements customers have regarding cable routing directions, JINPAT  design offers exceptional installation flexibility:

• Customizable Cable Lengths: Customers can precisely configure cable lengths based on actual on-site spatial distances, thereby avoiding cable accumulation issues caused by excess slack.

• Simplified Maintenance: When replacement or maintenance is required, users simply need to loosen the screws inside the junction box—completely eliminating the cable stripping and soldering processes typically required for traditional slip rings.

III. Maximized Space Utilization

Thanks to its compact mechanical structure, this slip ring maintains a large inner bore diameter of φ240mm while strictly controlling its outer diameter tolerances. For modern crane equipment—which prioritizes lightweight design and miniaturization—JINPAT slip rings undoubtedly represent the ideal solution for balancing high performance with a compact footprint.
