Curved Track Limitations
Cars will not roll on curved track if the radius is under the minimum listed below. A shorter car can
roll on a smaller radius. Refer to the chart below and make sure the radius is equal to, or greater
than the radius listed for the car. To find the radius go to www.harken.com.
Track for Unsupported Spans
Harken high-beam track is designed for unsupported spans.
The length of span depends on the load on the car. The higher
the car load, the less span the track can handle. If the car is
sized correctly, car length determines the spanning capability.
Longer, high-load (HL) cars require shorter spans because
the loads are so much greater. See track-spanning chart in
track instructions or at www.harken.com.
