6.1 Hoisting an RRU onto a Tower
This section describes the procedures and precautions for hoisting an RRU and its mounting kits
onto a tower. In tower-mounted scenarios, the RRU can be installed on a pole, U-steel, or angle
steel.
Prerequisites
When the RRU is powered by an AC/DC power module, you need to install the AC/DC power
module onto the RRU before hoisting them onto a tower. For detailed operations, see
AC/DC
Power Module User Guide or OPM15M User Guide .
NOTICE
l Do not stand the RRU upright because the RF ports cannot support the weight of the RRU.
l Place a foam pad or cardboard under the RRU to protect the RRU housing from damage
during the installation.
Procedure
Step 1
After climbing up to the tower, technician A secures the fixed pulley to the tower platform
support and leads the lifting sling through the fixed pulley.
Step 2
Technician C binds the mounting kits using the lifting sling and traction sling on the ground, as
shown in
Figure 6-1 . Then technician B pulls the lifting sling downwards, and technician C
pulls the traction sling outwards to protect the mounting kits from colliding with the tower.
