In the 1960's when U-S Safety Trolley set out to design an electric trolley system we kept two things in mind, first - most problems with mobile electrification arise at the conductor joints, second - on trolley systems those problems and even extended routine maintenance create downtime and downtime cost our customers money. Our Power System Engineering Team eliminated the conductor joints, simplified installation and created the Tri-Bar & Four-Bar electric trolley product lines. On our Tri-Bar & Four-Bar trolley systems, installation and maintenance are simple and straightforward, and the continuous copper conductor reduces hang-ups and derailments. This makes Tri-Bar & Four-Bar perfect for:
- crane electrification
- assembly lines
- cutting tables and sewing lines in the garment industry
- hanger doors
- monorails
The systems come in three and four bar models with or without grounding bars to provide a variety of electric power system design solutions for mobile electrification. The trolley systems can extend for hundreds of feet using continuous copper conductors, which are the ideal medium for communication and control signals for cranes and hoists. Our Tri-Bar & Four-Bar trolley systems can be factory shaped to your specifications into loops, ovals, circles, and multi-curved monorail tracks and modified with switches and disengagable trolleys. These custom systems are shipped for easy assembly on your premises.
