2. BAB I. RIGGING ANALYSIS
A. Winch
Base-mounted winches, or tuggers, are a compact, versatile tool for many hoisting
and pulling operations. They are particularly useful in areas not accessible to mobile
cranes or where there is not enough headroom for a crane to operate. Figure 1
shows a tugger and snatch block arrangement for hoisting. Make sure that the rope
leaves the drum at a downward angle and that the loose end is securely anchored.

B. Anchorage Points
Hoists, winches, tirfors, and other rigging devices require secure anchorage points.
Anchors may be overhead, in the floor, or at lateral points in walls or other structures.
The arrangement may involve columns, beams, beam clamps, welded lugs, slings, or
block and tackle. Whatever the method, riggers must be certain of the loads involved
and the anchorage required.
Lead Line Load Example A =
25 ton
1 line
= 25 ton
Lead Line Load Example B =
25 ton
6 line
= 4,167 ton ~ 5 ton
Load on structure A = 25 ton + 25 ton = 50 ton
Load on structure B = 25 ton + 5 ton = 30 ton
Load on structure = Load + Lead Line Load
Lead Line Load =

C. Angle effect to BLock Load
Analysis:
Load = 62 ton
Lead Line Load =
62 ton
8 line
= 7,75 ton ~ 8 ton
Load Block C = Load x Factor α deg angle (0o
)
Load Block C = 62 ton x 2 = 124 ton
.
Load Block D = Lead Line Load x Factor α deg angle (40o
)
Load Block D = 8 ton x 1.87 = 14.96 ton
.
Load Block E = Lead Line Load x Factor α deg angle (130o
)
Load Block E = 8 ton x 0.84 = 6.72 ton
.
Load Block F = Lead Line Load x Factor α deg angle (90o
)
Load Block F = 8 ton x 1.41 = 11.28 ton

D. Rigging Blocks
The design factor for rigging blocks shall be a minimum of 4.

E. Wire Rope Handling
Handling any kind of rope can be hazardous. Handling wire rope presents particular
hazards. Personnel should wear appropriate personal protective equipment such as
gloves and use caution to keep clothing or gloves from getting caught in sheaves or
drums during tugger/Winch operation.

F. Hand Signals
Hand signals shall be in accordance with ASME B30.7-2006 and shall be posted
conspicuously.
