Steam drum lifting
This document provides a rigging analysis for lifting a steam drum using a winch. It discusses the use of winches for hoisting, anchoring rigging components securely, calculating lead line loads, the effect of rigging block angles on loads, using wire rope safely, and required hand signals. Design factors for rigging blocks and lifting at an angle are also addressed.

- 2. BAB I. RIGGINGANALYSIS 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. Figure 1
- 3. 2 E-mail:gunawan_hagun@yahoo.co.id 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 = Load Parts of Line at Load

Angle effectto 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

- 6. 5 E-mail:gunawan_hagun@yahoo.co.id E. Wire RopeHandling 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.
