RGC PRO400 - 3.7 INSTALLING TRACK SUPPORT

WARNING:
MAKE SURE THAT BOTH TRACK SHOES ARE RESTING ON A FIRM, LEVEL SURFACE.
THIS PREVENTS TRACK SLIPPAGE OR UNEVEN LOADING OF TRACK WHICH CAN
CAUSE EQUIPMENT DAMAGE OR PERSONAL INJURY.
3.6.2 Procedure B
1. Insure a tie rope is holding the platform in position at the base of the track. Place track perpendicular to the building
with the bottom of the shoes resting against the building to prevent slipping.
2. Use a person on the roof to lower a tether rope from the roof. Attach the tether rope to the top bracket to pull up the
track with a person on the ground with their feet braced against the track shoes. A person on the ground may aid in
erecting by “walking” up the track hand over hand on the rails or cross ties.
3. When the track reaches a vertical position, carefully turn the track 180q with platform away from building. Move the
bottom of the track away from the building 1/4 of the height of the building where the track is to be supported.
Allowance must be made for an overhang on building. See Table 3-1 in Section 3.7 for approximate distances of base
of track from building.
4. Perform Steps 4 through 8 described in Section 3.6.1, Procedure A.
3.7 INSTALLING TRACK SUPPORT
Track lengths over 28 feet require the use of the track support. Table 3-1 provides the information for the track length, the
distance from the bottom of the track to the building, and the location of the track support for various building heights.
The base of track to building distance must be increased by the amount of any overhang on the building on which the
hoist is being used.

Track Support Location Requirements
1. Refer to Figure 3-4. Using the four 3/8 x 3/4” hex head cap screws, four 3/8” nuts, and four external tooth lock
washers, securely fasten both the flanges and the knuckles of the support. Align the outermost pairs of mounting
holes to make the knuckles flush with the end of the corresponding flange.
2. See Figure 3-4, & refer to Table 3-1 to determine the cross tie on which to mount the support. With the track installed
in its operating position against the building, use a ladder to raise the track support and knuckle assembly to the
selected track cross tie. Fasten the track support knuckles to the cross tie using the provided lock pins.
