What is the psi capacity based on crossgrain bearing
200psi to 1000
What is the equation to find crib capacity
Psi X height X width X no. Of bearing points
When lifting on a crib tower do not allow what?
The height to exceed 1 1/2 times the width at the tower base
Lifting capacity is determined by the bags what?
Length x width X psi
Psi = 118 just use 100 to simplify
How do you wrap a 15’ chain
Minimum of 1 1/2 times and hook chain back on itself
