Installation of the Spring Hanger
Confirm the distance between busway and wall according to
the project. The recommended distance shall be more than
100mm;
Manufacture channel steel for installation, with its size
matching on-site requirements;
(Make sure that the diameter of hole in the channel steel is
Φ18mm in order to match with Φ16mm spring bolt . Make
sure that the distance between holes of L angle steel are in
line with the distance of the holes in the channel steel.)
Before fixing, make sure all the channel steels at the floor
are in the same vertical line. (Please refer to the figure 2.14)
Drilling hole according to the dimension shown in the figure
2.14 in advance is a selective option.）
• Measure B dimension on site.
"B " dimension means: the distance from surface of the floor
to busway end installed under the floor ( please refer to the
fig 2.14)
• By calculating C dimension ="L-B-278" ( 278 mm means: the
height of 10# channel steel +178mm, please refer to the
figure 2,14) , we can fix the position of L type angle steel to
be connected with busway.
• The width of the angle steel is consistent with the height of
busway (please refer to the Page 5, table 1 and table 1.1)
Suspend the busway, ensuring the distance from the center
of busway joint to the floor is ≧ 560mm.
According to the figure 2.14, ensure the fixed size of 178mm,
fix double-headed bolt to the channel steel, then put the
spring and set the spring hanger.
• Fix the spring hanger to the buway by using M 6 screw.
• By wrenching the nut "7", set "H" dimension.
• By loosening the nut "4", raise it to the top of the spring
studs.
• NOTE: Failure to properly adjust the spring hangers could
damage the bus and void the warranty.(To set "H"
dimension, please refer to the below step:)
• The springs can be adjusted as shown in (Fig 2.14).
Determine the required dimension H of the hanger springs,
found on the layout drawing or by using the formula below
H=150-(1.5W/K*n)
W=( Busway wt/m x m/floor + devices on floor)
Note:
H: The reference dimension of the spring for installation;
W: The weight of Busway each floor. This can be calculated
with the weight per meter (checking the Table 1 and Table 1.1)
& the height of each floor (checking the Fig1.2).
K: The press of the spring each mm. K=9.375 kgf/mm
n : The number of spring each floor.
150: The initial dimension of the Spring.
1.5: The revise quotiety.
