Knight Global Enclosed Track Aluminum Rail Series, Capacity 1100 lbs - KG RAD4110

Knight's RAD4110 Aluminum Rail Series has an enclosed track design that is extruded from a lightweight, high-strength aluminum alloy. The lightweight aluminum rail eases installation and reduces overhead requirements. The enclosed Series Rail is the ideal solution, whether your load is located directly under the system or cantilevered off to the side. This series, combined with nylon trolley wheels, provides the lowest rolling resistance in the industry.

Features:

Mechanical Properties: ASTM B221 6005-T5 Series Aluminum
Multiple Overhead and Floor Mounted Configurations
Supports Trolleys, End Trucks and Hangers
RAD4110 Rail Lengths: Up to 25 ft [7.6m] without Splices

Benefits:

Transfer Loads in the "X" and "Y" Directions
Multiple Pre-Assembled Accessories
Accessories can be positioned along the rail, no welding required
Load Trolleys and End Trucks are designed for cantilevered and direct load applications
All Hangers and End Trucks are designed to prevent binding of bridges and runways.

Specifications:

Maximum Capacity: 1,100 lbs. [499kg]
Weight: 4.3 lbs/ ft [6.23kg/m]

*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) or 1:450 (1" of deflection in 450" 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. (113 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

Cantilevered Capacities (based on an optimum 8ft hanger span)

Cantilevered	Deflection Criteria
Cantilevered	1:350 Capacity*	1:450 Capacity*
1 ft [0.3 m]	100 lbs [45 kg]	75 lbs [34 kg]
2 ft [0.61 m]	50 lbs [23 kg]	35 lbs [16 kg]
3 ft [0.91 m]	125 lbs [57 kg]	100 lbs [45 kg]
4 ft [1.20 m]	35 lbs [16 kg]	30 lbs [14 kg]

Elastic Deformation: This type of deformation is reversible. Once the forces are removed, the object returns to its original shape. The elastic range ends when the material reaches its yield strength. At this point deformation begins.

Plastic Deformation: This type of deformation is not reversible. Once an object reaches this point, it will not return to its original shape. Plastic deformation ends with the fracture of the material.

Knight Global follows material handling industry standards in determining the capacity ratings for enclosed track overhead workstation crane systems. Each component (e.g. rail, hangers, trolleys, etc.) is individually tested to establish its ultimate failure point. From this number, a safe working load is then assigned to the component. Each rail span length is then tested to determine the maximum single point load required to achieve a predetermined deflection based on a 1:350 ratio (1? of deflection for each 350? of length). The recommended rated capacity chart is based upon single point loading for the listed spans.
