CAUTION
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.
Place the fiber coiler for coiling fiber optic cables on the fiber spools, and bind the fiber
optic cables using the lifting sling and traction sling.
Installation engineer B rotates the fiber spools at the speed of 5 m (16.4 ft.) to 15 m (49.21
ft.) per minute to coil the fiber optic cables.
Installation engineer C pulls the lifting sling downwards, and installation engineer D pulls
the traction sling outwards to protect the fiber optic cables from colliding with the tower.
