Grove GMK 6350-1 Crane Setup Formula

• Groove Drum =3.9' or 1.2 Meters
• 6 Sheaves
• Lift = 11 Tons Modular Home
• Angle Factor = 60° {Lead Sheave}
• Winch ÷ 2 x Freight Angle (1.2 Meters ÷ 2 x 12 Groove Drum =} 7.2 Meters
• NOTE: Lead Sheave has to be 7.2 Meters (23.63') Away Min. Distance
• Bicket Load (BL)
• BL ÷ Falls (11 Tons ÷ 6 Sheaves = 1.84 Tons

Friction

• Lead Line - Bicket Load x Sheaves ÷ 20 + Bucket Load (1.84 Tons x 7 Sheaves ÷ 20 + 1.84 Tons = 2.49 Tons
• Round Strand 6 x 24 Fibre Core [6x24 {15/9/F)] 
• Nominal Diameter = 18mm (0.708661")
• Head Sling - Lead Load + Load (2.49 Tons x 60° [1.73] = 4.31 Tons

Angle Factors

• 120° - 1 (√1 Square Root of 1 = 1)
• 90° - 2 (√2 Square Root of 2 = 1.41)
• 60° - 3 (√ Square Root of 3 = 1.73)

Distance To Lead Sheave Formula

• Winch÷ 2 x Fleet Angle (Grooved or Ungrooved Drum)

Lead Line Formula

• Bicket Load or Load ÷ Falls 
• Lead Line = Bicket Load x Sheaves ÷ 20 + Bicket Load
• Head Sling = Lead Load + Load
• Load Lead Sheave = Lead Load x Angle Factor

Precast Concrete Transport & Lifting Specs.

Length - 12' (3.66 Meters)

Width - 4' (1.22 Meters)

Height - 75' (23.86 Meters)

Dry Weight - 264 Tons (257,808 Kilograms)

Weight + Friction - 426 Tons (386,712 Kilograms)

Volume Lift Formula:

• NOTE: Concrete is 2400 Kilograms Per Cubic Meters
• 3.66 Meters x 1.23 Meters x 23.86 Meters = 107.42 Cube Meters
• 107.42 Cube Meters x 2400 Kilograms = 257,808 Kilograms
• Add 50% For Friction
• 257,808 Kilograms x 1.5 = 386,712 Kilograms
• Height x 50% = (23.86 Meters x 1.5 =) 35.79 Meters [117.5']

Winch Rope

• 35.79 Meters [117.5'] x 35.79 Meters [117.5'] = 1,280.93 Meters [4,203' (Distance Away from Other Buildings)
