Vertical hangers (Figure 47 and Figure 48)
When busway is to be installed vertically, a spring suspension type
vertical hanger should be used. Vertical hangers are not provided
unless specified.
This unique hanger equalizes the weight of vertically mounted
busway along all supports. A vertical hanger must be used on
each floor and at the end of the bus run on the last floor.
Intermediate hangers are required for floor heights exceeding
16 ft (4.9 m).
