Crane Electrification

Crane electrification was one of the most popular uses of the U-S Safety Trolley product suite when it was first introduced, and this remains the same today.

Span-Guard was the first of the joint-free crane conductor systems introduced decades ago, and has been powering cranes ever since. Developed first in the 1950s to meet the conditions of steel mills, the system’s patented self-sealing vinyl cover protects the conductor from harsh environments, and ensures your cranes will have continuous power no matter the conditions. The Span-Guard crane power supply is available in 250 and 520 amps.

All joint-free systems in the U-S Safety Trolley product suite have become the crane power supply of choice.
