Under normal conditions when a man exerts a pull of 70 lb when backing up a wire, each turn round a bollard reduces the strain required on the hauling part to one-quarter of the load, so that one man will be able to hold: one-eighth of a ton with one turn, half a ton with two turns, two tons with three turns, and eight tons with four turns.
Ngaphantsi kwezizathu ezizizo, xa indoda isebenzisa utsalo olungu 70 1b xa incedisa ecingweni, elinye lamathuba okujikeleza intsika luyancitshiswa lutsalwe ngamandla afunekayo, ekwahlulweni kotsalo kwikota enye kumthwalo ukuze indoda enye ikwazi ukubamba enye kwisibhozo seetoni nethuba elinye, ihafu yetoni kumathuba amabini, iitoni ezimbini kumathuba amathathu neetoni ezisibhozo kumathua amane.
