The load-bearing capacity of each sling must be greater than 200 kg (441 lb) and the
diameter of each sling must be less than 25 mm (0.98 in.).
When hoisting each device onto a tower, protect them from colliding with the tower.
Hoist the RRU onto the tower before it is installed on a pole, angle steel, or U-steel.
Do not hoist anything using the traction eye.
Step 7
Installation engineer A catches the RRU hoisted onto the tower.
Step 8
Installation engineer A installs the RRU onto the main bracket and uses an inner hexagon
torque screwdriver to tighten the captive screw into the hole of the attachment plate and main
bracket to 5 N·m (44.25 lbf·in.). For detailed operations, see steps 4 and 5 in 7.2.1 Installing a
Single RRU.
Step 9
Untie the lifting sling and traction sling.
The procedure for hoisting the RRU and its mounting kits onto the tower is for your reference only.
