Machines and Sheaves located below or at one side of a hoistway shall be anchored to beams, Foundations or floors with bolts, conforming to A.S.T.M. Specifications A307-64, of sufficient size and number to withstand the applicable load conditions specified in Rule 105.2b. Based on these initial load, total tension in anchor bolts shall not exceed seven thousands (7000) pounds per square inch of net section and the total shear shall not exceed seven thousands (7000) pounds per square inch of actual area in the shear plane. Where bolts are used through sloping flanges of structural shapes, the boltheads shall be of the tipped or beveled-head type or shall be fitted with beveled steel washers, and nuts or sloping flanges shall seat or beveled steel washers. Exception: Bolts made of steel having a greater strength than specified by ASTM Specification A-307-64 may be used and the maximum allowable stresses increased proportionately based on the ratio of the ultimate strengths. Elongation must conform to the requirements of the corresponding ASTM Specification.
