Berdasarkan buku ”Marine auxiliary machinary and system”
karangan M Khetagurov.
Daya tarik
cable lifter untuk mengangkat 1 jangkar :
Tcl = 1.35 * (Ga + pa * La)*(1 - 1025/7750 = 1.17 * (Ga + pa * La)
Dimana :
Ga =
berat jangkar, N, kg.
pa =
berat tiap meter rantai jangkar, N, kg.
La =
panjang rantai jangkar yang menggantung, m.
Diameter cable lifter :
Dcl = 0.013 * dc (m)
Dimana
:
dc = diameter rantai jangkar, mm.
Torsi pada motor :
Mr = Tcl *dcl / 2*Ia * Na (N m) (kg * cm)
Dimana
:
Ia = garing ratio of mechanism, 105
s/d 250.
Na = overall efficiency of the mechanism, bila dengan worm
gearing, 0.65 s/d 0.75
