7.1 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
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 RF ports cannot support the
weight of the RRU.
l
The routing and protection of power cables should follow the local safety regulations,
industry standards, and enterprise standards of the operator.
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
. 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.
