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
