What should be the length of the slings?
Angles of equipment
length: 20 ft = 6 m
width: 8 ft = 2,4 m
equipment:
four-legged sling
! External angle maximum 45° top angle maximum 90°!
relationship angles - length of the slings
What should be the length of the slings?
1. Calculate diagonal AC or BD
AB = 20 ft = 6 m
BC = 8 ft = 2,4 m

2. Calculate length of sling with AE
slings with an excluded angle of 45°:
AC = 6,46 : 1,4 = 4,63 m
AC = 6,46 m
C
6² + 2,4² = AC² 36 + 5,76 = 41,76
AC = 6,46 m
45º
length of the slings: 4,63 m
