Knight Global Curved Aluminum Rail

Series: RAD4112 / RAD6112 / RAD7512

The Knight Global RAD4112, RAD6112 and RAD7512 curved aluminum rails use a curved enclosed track extruded from lightweight, high-strength aluminum alloy. The design lets loads travel smoothly around corners and past fixed obstructions in the plant.

The curved rail system is ideal for direct loading on single curved sections. Combined with dedicated nylon trolley wheels, it delivers the lowest rolling resistance in the industry, so operators can move loads with little effort and high precision.

It is well suited to lines that require non-linear routing - it optimizes floor space and extends working coverage without complex auxiliary rails.

*Note: Aluminum alloy material to ASTM B221 6005-T5. Custom curve radii are available per project. Accessories can be positioned anywhere along the rail with no welding required.

Load Capacity Tables by Model

*Deflection criteria: Each hanger spacing is tested for the maximum single point load that produces a deflection ratio of 1:350 (1" of deflection per 350" of length), 1:450 (1" per 450"), 1:550 (1" per 550"). The load tables are based on single point loading.

Deflection Standards & Ergonomic Force Explained

*The 1:350, 1:450 and 1:550 standards explained:

For ergonomic reasons, each rail span is tested to determine the

maximum single point load

allowed to reach a predetermined deflection at the following ratios:

1:350 = 1 inch of deflection per 350 inches of rail length (more flexible, heavier loads).
1:450 = 1 inch of deflection per 450 inches of rail length (stiffer, better ergonomics).
1:550 = 1 inch of deflection per 550 inches of rail length (stiffest, optimal ergonomics).

Operating Force Estimation Formula

To quickly estimate the ergonomic operating force, use the formula:

Fs = 0.017 × Total Mass = Maximum Force (lbf) to Overcome Inertia

The force needed to keep the load moving (Fk - kinetic friction force) equals 0.35 × the force to overcome inertia (Fs).

Example: Mass 250 lbs (113 kg)
→ Fs = 0.017 × 250 = 4.25 lbf (1.9 kg) to overcome inertia
→ Fk = 4.25 × 0.35 = 1.48 lbf (0.67 kg) to keep the load moving

Elastic Deformation

Deformation that is recoverable. When the load is removed, the part returns to its original shape. The elastic range ends when the material reaches its yield strength, after which plastic deformation begins.

Plastic Deformation

Deformation that is not recoverable. Beyond this limit, the part does not return to its original shape. It ends in material fracture.

Knight Global follows material handling industry standards when rating workstation crane rail systems. Each component (rail, hanger, trolley...) is tested individually to establish its ultimate failure point, from which the safe working load is assigned. The recommended load tables are based on single point loading at the listed spans.
