Procedure
Step 1 After climbing up to the tower, installation engineer A secures the fixed pulley to the tower
platform support and leads the lifting sling through the fixed pulley.
Step 2 Installation engineer C binds the mounting kits using the lifting sling and traction sling on the
ground, as shown in Figure 7-1. Then installation engineer B pulls the lifting sling downwards,
and installation engineer C pulls the traction sling outwards to protect the mounting kits from
colliding with the tower.

Step 4 Install the mounting kits. For detailed operations, see steps 1 to 3 in 8.2.1 Installing a Single
RRU.
Step 5 Installation engineer C binds the RRU using the lifting sling and traction sling, as shown in
Figure 7-2. The binding methods in Figure 7-3 and Figure 7-4 are incorrect.
Issue Draft B (2018-05-15)
Do not stand the RRU upright because the RF ports cannot support the weight of the RRU.
Place a foam pad or cardboard under the RRU to protect the RRU housing from damage
during the installation.
