Electrification of Excavators Has Never Been Easier

Penlink offers advanced slip ring solutions for the electrification of excavators, supporting mid-voltage transmission for efficient power transfer in both surface and underground operations.

These slip rings feature durable SS 304 stainless steel housing, adaptable environmental protection (IP54 to IP65), and compact form factors for easy integration into space-constrained areas. They ensure reliable performance and continuous 360° rotation, reducing maintenance and downtime.

We also provide smaller components for excavators and tools. Our modified electrical slip rings offer a wide range of power and data signals (CAN Bus, DeviceNET, Ethernet, EtherCAT, PROFIBUS, PROFINET, and other protocols on request).
