BEAR-LOC®
- Lock Length Selection Chart
Lock Selection Procedure:
- Choose hydraulic system pressure (2000 to 5000 psi)
- Use "rod" diameter consistent with structural load requirments.
- Determine load to be locked (Maximum design load times desired safety factor).
- Using chart find luck lenght required.
Example:
- System Pressure - 300 psi.
- 4 inch Rod.
- (48,000)(1.25) = 60,000 Lbs.
- Lock Unit - (-14) 61,000 Lbs.
- Lock Length (L) is 15.25"
