The Speedway Heavy Duty Cantilever (HDC) provides a specific
means of supporting Speedway cable ladder on vertical fixed
structures or channel (strut type) uprights.
The heavy duty cantilevers are available to suit Speedway
SW4, SW5 & SW6 Cable Ladders for all widths up to and
including 900mm wide.
Each Heavy Duty Cantilever has fixing slots to accept the
Speedway External Flange Clamps (SW/EFC/#), Adaptable Fixing
Brackets (SW/AFB/#) and Hold Down Brackets (SW-/HDB/#).
The slot pattern allows the adaptable fixing bracket to be
fitted either internally or externally on the Speedway cable
ladder. The heavy duty cantilever arm back plate has a
minimum of two 15mm diameter fixing holes (see table below
for details) to accept fixings up to and including M14. The
loading table below gives the recommended maximum load for
each size of heavy duty cantilever arm for supporting uniformly
distributed loads (UDL) such as or for supporting Speedway
cable ladder (which should be uniformly loaded to apply two
equal point loads onto the cantilever arm).
