Knight Global Electrified Rail Systems, Capacity 1140 lbs - KG ERAD4000
Electrified Rail Systems are a complete power supply suspension system that can be used in combination with a Knight Servo System, VFD tractors, power tools, and other electrical devices. The ERAD Series is a fully enclosed electrical system that eliminates the stack-up of runway festooning. The power travels through a conductor power rail (ERail), mounted on top of Knight's ERAD4000 ergonomically friendly aluminum rail. The standard ERail is equipped with (4) four poles, nominal current 60 amp, 240/480V which can run multiple systems on (1) one rail assembly.
Features:
- Patent Pending
- Fully Enclosed Electrical System
- Horizontal curved sections available
- Compliant with International Standards
- Added safety against shock
- Knight's unique hanger design allows for adjustments while leveling the system
Benefits:
- Eliminates stack-up of festooning trolleys and hanging electrical cables
- Simplifies installation by including electrical rail within suspension
- Eliminates need for tow bars
- Stacked compact design eliminates need from installing load rail and power rail separately
- Twice the power of the competition
Specifications:
- ERail Electrical Capacity: Up to 60 amps / 690 volts
- Max Weight Capacity: Up to 1,140 lbs [517 kg]
System Component:
ERail:
Available in 4 poles with a nominal current of 60 A. Optional 5, 6, and 7 poles available upon request.
ERail Conductor Trolley:
Travels inside of the ERail and is combined with the Knight load trolley. Copper graphite shoes are used for energy and control voltages over 35 V.
ERAD4000:
Combined with Knight's load trolleys, provides the most ergonomically friendly rail system. Rail comes in lengths up to 25ft [9.1m] without a splice. Capacities up to 1,140 lbs. [517 kg].
Suspension Points:
Knight adjustable hangers and End Trucks support both the Load Rail and ERail. Hangers have the ability to mount to I-Beams, C-Channels, Angle Iron, and many others.
ERail End Caps and Stops:
Attaches to the end of the ERail Series Rail. The Redundant End Cap is primarily used to prevent load and ERail trolleys from exiting the rail.
Power Supply End Feed:
Power supply feed for ERail. Comes standard with 4 poles, 5-7 poles available upon request.

*Due to Ergonomic considerations, each rail span distance is tested to determine the maximum single point load required to achieve a predetermined deflection based on a ratio of 1:350 (1" of deflection for each 350" of length), 1:450 (1" of deflection in 450" of length) or 1:550 (1" of deflection for each 550" of length).
For purposes of estimating approximate ergonomic force requirements, the following formula may be used:
0.009 x total mass = maximum effort (in lbf) required to overcome inertia. Effort required to sustain movement is generally 0.35 x effort to overcome inertia e.g., 250 lbs. (1.03 kg) mass x 0.009 = 2.25 lbf (0.9 kg) to overcome inertia, 2.25 (0.9 kg) x 0.35 = .79 lbf (0.36 kg) to sustain movement
