1:1 Replacement Slip Rings
Our standard slip rings for mobile cranes are engineered for durability and performance in demanding environments. These modified electrical slip rings support a wide range of power and data transmission protocols, including CAN Bus, DeviceNET, Ethernet, EtherCAT, PROFIBUS, PROFINET, and more upon request.
Designed with a compact form factor and a hollow shaft configuration, they are ideal for space-constrained applications while ensuring reliable signal integrity and power transfer. Whether for heavy-duty construction or precision control systems, our slip rings deliver seamless connectivity and long-lasting operation.
Hydraulic Rotary Unions
At Penlink, we specialize in high-performance rotary unions designed specifically for off-road vehicles operating in the most challenging conditions. Our rotary unions ensure reliable, leak-free transfer of hydraulic fluid, air, or coolant between stationary and rotating components—critical for maintaining system integrity in mobile platforms exposed to vibration, shock, and environmental contaminants.
Robust Magnetic Encoders for Mobile Cranes
Penlink’s magnetic encoder solutions are built to deliver accurate position feedback in the demanding environments of mobile crane operations. Engineered for durability and precision, these encoders perform reliably under heavy vibration, extreme temperatures, and exposure to dust and moisture.
Featuring non-contact sensing technology and compact, rugged designs, our magnetic encoders support advanced control systems for boom positioning, rotation, and load handling—enhancing operational safety, responsiveness, and efficiency on-site.
