the piece to be hoisted is cylindrical, the size is phi 1220 multiplied by 21500, the weight is 11.2t, and the installation position elevation of the piece to be hoisted is 5.2m.
(2) Selecting steel strands:
due to the fact that the in-place elevation of the equipment is 5.2m and the hydraulic equipment is arranged on site, the length of the steel strands is 12m, the diameter of the steel strands is 15.5mm, the tensile strength of each steel strand is 1850N/mm < 2 >, the weight per meter is 1.1kg, and 4 steel strands are selected according to the total weight of the equipment of 11.2t, and the left-handed steel strands and the right-handed steel strands are right-handed steel strands.
(3) Device for calculating the maximum lifting force G max ：
G max ＝﹙G 1 +G 2 ﹚K 1 K 2
In the formula: g 1 -total weight of equipment; g 2 -the steel strand weight; k 1 -dynamic load factor, taken as 1.2; k 2 -load uneven coefficient, taken as 1.1.
G max ＝﹙G 1 +G 2 ﹚K 1 K 2
＝﹙11.2+0.5﹚1.2×1.1

L 1 ＝6000×cos38°―1450sin38°＝3853.83(mm)
L 2 ＝6000×cos38°+1450sin38°＝5620.77(mm)
the following can be calculated respectively from the above:
T 1 ＝G max ×L 2 /(L 1 +L 2 )＝15.444×5620.77/(3853.83+5620.77)＝9.16(t)
calculate T in the same way 2 ＝6.28(t)
