RAD7512 Curved Series Aluminum Rail
Knight Global's RAD7512 Curved Series Aluminum Rail has a curved radius enclosed track design that is extruded from a lightweight high strength aluminum alloy. Knight's RAD7512 Series Rail design allows loads to travel around corners and stationary objects. The RAD7512 Curved Series Rail is the ideal solution for direct loads on single curved sections. Knight's RAD7512 Curved Series Rail combined with nylon trolley wheels, provides the lowest rolling resistance in the industry.

* 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 L/350 (1” of deflection for each 350” of length), L/450 (1” of deflection in 450” of length) or L/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

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 tic 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.
