6.1 Hoisting an RRU 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.
Prerequisites
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.
Two RRUs cannot be installed on the side or on a pole in back-to-back mode, 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

traction sling, as shown in
