However, for controlled situations where the loading is predictable, a Factor of Safety.7 may be used. The safe working loads shown in the table are for props used either vertically or horizontally. In horizontal applications, the props should always be used with the strong axis vertical. Mabey Tubular Props are an alternative to s for any of the applications shown. Tubular Props and Soldiers should not be combined in any single prop. For props, a recommended straightness tolerance is given below, indicated by Max Offset Dim (in.). Should the prop fall outside the range shown, the components should be checked for local damage to end plates. All bolted components require bolts. 6 number when connecting Mk3 prop to Mk3 prop. Use 4 bolts when attaching an 9 or 0 foot. Intermediate lengths may be obtained by adding or.8 Units (-360 or 4), or in some cases screw jacks can be fixed at each end. Allowance to be made for ellastic shortening of Push Pull Prop =.0007 in/kip/ft. A kit assembly reference is given to assist in ordering the props. The kit includes all parts and bolts necessary depending upon the manner in which the prop is used. The kit assembly reference number must be followed by the A, B, or C suffix, i.e., a Type 9 Prop to support Mk Soildiers would be called off as KP/9C. 5 : SYSTEM60

11 System 60 Bracing of Shores Essential Requirements Careful consideration should ALWAYS be given to bracing which may be required for the reasons given below. A combination of standard scaffold fittings are normally used for bracing. See page 4 for typical connection details. a) Stability of Propping During Installation If the structure requiring propping can provide adequate lateral stability once the props are in position and fixed top and bottom, then the props only need to be braced to ensure stability during installation. In these cases, the bracing needs to be design for the lateral loadings to be expected during installation (e.g., wind). Structure being propped provides lateral stability Props braced during installation Bracing removed AFTER fixings installed at top and base Provided the props are subsequently released and removed one at a time, it may not be necessary to brace the props during dismantling. Provided the props are subsequently released and removed one at a time, it may not be necessary to brace the props during dismantling. b) Stability of a Propping System Which Needs to Provide Lateral Stability as Well as Support Vertical Loading If the propping system is required to support vertical load AND provide lateral stability, then bracing will always be required. In these cases, the bracing system needs to be designed to carry a minimum of.5% of the vertical load on each prop, or the actual horizontal forces applied if these are greater (e.g. wind, non-verticality of legs, etc.).

The Connector Plate is free to move through 360, allowing the needle to be located at any position on top of the soldier. The Washer N-00 does not clamp tight, but holds the Connector Plate captive to the soldier end plate. The Tilting Head 53 (which provides 5 max tilt) fits on top of a vertical, providing a connection to a horizontal Header Beam. The Needle Beam is then positioned on top of the Header Beam at 90 to it. The Tilting Head provides fine vertical adjustment, and the use of this arrangement allows the vertical props to be spaced at greater centers than the Needle Beams.
