More than40 ton need lifting plan sketch design by auto cad it is procedure of lifting equipment which show you kind of crane capacity of crane of weight of crane type of steel wire,shgal,hook and dead point of the crane maximum and minimum loading capacity of crane and many other.
Lifting Plan or Rigging Drawing, It provides you a projected Drawings in multi views such as Top/Section/End View/Crane Specification/Lifting Specs. Top View to verify clash points on existing sorounding structures, access and egress of trailers (SPMT), crane travel. The drawing should consist the following; PICKING Pnt.-SLEWING-INSTALLATION, the section of the drawing will reflect how far the crane from any underground installations or from open pits and the distance of any part of the load or rigging tackle nearest to the crane boom. (Specification Table) Crane Specification will be the assembly of the crane, the length of the boom, number of counter weights, length of mast used, crane capacity at current working radius. Lifting Specification Load Weight, rigging tackle weights (shackles,slings,lifting/spreader beam) hook block wt.,Ground Bearing pressure, Tipping of Load & Tipping Over Calcs, then finally you have to prepare the Method Statement. These information may not be enough as maybe your client needs a more concise technical information in regards to the project.
There are different types of lifting plan as per requirment of lift. such as routine lift plan, moderate lift plan, complex lift plan in this situation is more than 150 lifting plan is recommended criticle lift paln because or the weight so that means heavy lifting equipment capasity and rigging gears will be using. need to check ground condition barriering capacity. need high rigging study involve with plan.
I don’t have auto CAD, so this should be descriptive enough to illustrate the plan of action. Safety always comes first; that the load path is clear of obstructions, including people. Port crane, single jib portal crane of capacity ranging from 10 to 200t, hook working load shall be equal to or greater than the rated load of the steel wire rope. Standard right regular lay steel rope. A shackle is needed on the hook since three or more sling eyes are needed for such a heavy load. Hook tip should point out and away from the load to assure when slack is taken up the hook will not tip load. A tagline shall be used for additional security and control.
