NOTE
Hoist mounting kits onto the tower and then install the mounting kits before hoisting the RRU onto the
tower. When hoisting the mounting kits and RRU, protect them from colliding with the tower.
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.
Installation engineer C binds the RRU using the lifting sling and secures the traction sling
to the RRU handle.
Installation engineer B pulls the lifting sling downwards, and installation engineer C pulls
the traction sling outwards to protect the RRU and mounting kits from colliding with the
tower.
Installation engineer A catches the RRU, install the RRU on the main mounting bracket
until the RRU snaps shut, and then unties the sling.
NOTE
The procedure for hoisting the RRU onto the tower is for your reference only.
