Spanguard Corporation

For more than 60 years, U-S Safety Trolley has been a leader in customizable, flexible power distribution for industrial sites. Recognizing that electrical joints were the most common sources of problems in crane electrification, U-S Safety Trolley engineers designed their unique “no-joint” product solution to meet the needs of industry. Advantages:* Eliminates the most common source of crane electrification failure, joints * Installs faster – significantly less time than jointed conductor bar systems * Under tension – No expansion joints required * Virtually maintenance free * Corrosion resistant in harsh environments Span-Guard Plant managers, engineers, crane operators, and others with extensive crane experience know that electrical joints are the most common source of crane electrification problems. Among other things, electrical joints become loose over time, overheat, expand and contract, and can cause a loss of power. Span-Guard was the first continuous electric conductor bar introduced. Uniquely designed without joints in the copper conductor with a flexible, fully-enclosed, insulated cover, Span-Guard is the most reliable, highest quality, conductor system on the market. This jointless conductor is ideal for cranes, hoists, and moving equipment where problems and downtime cannot be tolerated. Tri-Bar/Four-Bar: Tri-Bar/Four-Bar continuous electrical conductor bar systems have been a longtime favorite among customers. The joint-free construction, easy installation and maintenance, and custom fabrications make the Tri-Bar/Four-Bar the sensible choice in electric trolley bar systems. This product is commonly used in various types of assembly line manufacturing, aircraft hangar doors, amusement park rides, workstations, and monorails.
