Quality, Reliable Power Supply to Moving and Stationary Equipment

Four-Bar systems are specially designed with no joints in the solid copper conductors, and feature multi-con­ductor modular housing. Joint-free copper conductors are cut to length for each job requirement and shipped in a coil in one piece for track runs up to 600' long.

Trolleybar's joint free design provides "Clean Power"; hot spots and arcing are virtually eliminated. Today's automatic spreading machines incorporate sensitive micro processors. This "Clean Power" is es­sential for trouble free operation.

Four-Bar systems have a wide variety of useful ap­plications including electrification for sewing machines, cutting knives, spreading machines, conveyer systems, automated moving equipment, material handling equip­ment, etc.

Installation is fast and easy. The insulated housings come in standard 20 foot lengths (or 6 meters), and interlock. Then the conductors slide easily into the housing slots from one end. One person can push in shorter runs. With its strong, lightweight PVC housing, U-S Safety Trolley can be installed over the table or directly to the table legs.

Joint Free Design

The feature of continuous, joint free, electrical conductors for the entire length of the run elimi­nates the weakest part of any electrical systems - the joints. One-piece copper conductors are cut to each job requirement ant­ shipped in a coil.

Reliable

Four-Bar is the solution for these problems:

• Downtime due to arcing.
• Loose joints
• Expansion
• Misalignment
• Trolley Interference

Solid Copper Bars

Used for electrical efficiency, quality and reli­ability.

Compact

A single housing for up to 5 conductors keeps space requirements to a minimum. Multiple runs can be stacked side by side.

Variety of Trolley/Taps

Taps can be either stationary or mobile: Power is tapped from the busway with easy to install and remove POWER PICKUPS and POWER JACKS. POWER JACKS are stationary on the busway, while the POWER PICKUPS can be pulled along the busway via a chain to provide power to moving equipment. POWER PICK­UPS can be used for operation speed up to 85 yards per minutes. They come in various rat­ings from 15 to 50 amps. The POWER PICKUPS have an integral junction box with receptacle and fuse options. Supplying power to a machine is easy ... connect the power­cord to the power tap of your choice and to your machine ... snap the tap on the busway. Push the start button and you are in operation. Typical places where busway can be useful:

• Sewing Machines
• Cutting Tables
• Spreading Machines
• Assembly Lines
• Maintenance Areas

Fast and Easy to Install

Four-Bar systems have fewer parts. This means the system installs fast and easy, thus minimizing installation cost. Installation is ac­complished with pocket tools.

• Step 1 : Mount the housings for the full length required
• Step 2 : Push-pull each precut length of con­ductor through empty slot in housing
• Step 3 : Connect feed wires

Safe

The housing of Four-Bar systems are made of an insulated, high impact PVC compound, pro­viding safety as well as rugged durability of the system.
