6.6 Hoisting the RRU and Mounting Kits onto a Tower
Before installing an RRU on a tower, bind the RRU and mounting kits and then hoist them onto
the tower. The RRU can be installed on a pole, U-steel, or angle steel. This section describes the
procedure for hoisting the RRU and mounting kits onto the tower and the precautions that must
be taken.
Prerequisite
Place a foam pad or cardboard on the ground to protect the housing of the RRU from damage
before the binding. Do not stand the RRU upright because the load-bearing capacity of the RF
ports at the RRU bottom is low.
CAUTION
When installed on a tower, only one RRU can be installed in standard mode or reverse mode,
and two RRUs can be installed on a pole in back-to-back mode. RRUs cannot be installed on
the side, and the brackets for more than two RRUs cannot be combined.
Procedure
Step 1
Bind the RRU and mounting kits properly using a lifting sling, as shown in
.

Step 2
Bind the RRU by leading the lifting sling along the bottom of the attachment plate and through
the RRU handle. Then, bind mounting kits to the lifting sling and bind the RRU handle to the
traction sling, as shown in
