1.4.2 Allowable Stresses

1.4.2.1 Structural Items

Structural items associated with the hydraulic power system, such as support beams, shall be designed to withstand the maximum force exerted by the hydraulic cylinder plus any dead loads with a factor of safety of 2 based on the yield strength of the materials involved.

1.4.2.2 Hydraulic Cylinders

Design the hydraulic cylinders to withstand the maximum operating pressure in the system with a factor of safety of 5, based on the ultimate strength of the material, or 2, based on the yield strength of the material. Apply a factor of safety of 3 to the compression load when designing the hydraulic cylinders to resist buckling.

SECTION 41 24 27.00 10 Page 7
