CAUTION
It is imperative that rope reel or coil rotates as rope unwinds. If coil or reel does not rotate the wire will be twisted as it is uncoiled and kinking will result. A kinked rope may be damaged and unsafe for maximum service.
b)Before removing the old rope, refer to reeving diagram, Figure
c)Removing old rope. Please, refer to the Section IX Parts lists to assist in locating components referred to in the following paragraphs.
(1)Lower the lower block to a scaffold 6 to 7 feet below hoist to relieve tension on wire rope. (Lower block may be lowered to the floor if desired; however, to handle less weight and for ease of reeving, adequate scaffold below the hoist is recommended.)
FIGURE 5-6. Reeving Diagram – 4 Part Single-Reeved. (Note: Arrow on Drum Indicates Direction of Drum when Lowering.)
CAUTION
Be certain all personnel are clear of hoist as components, hardware, and wire rope are removed from hoist.
(2)Remove block operated limit switch weight from rope.
(3)Remove retaining rings from lower block sheave pin.
