    1. Technical Specifications System Description The Acrow POWERSHORE 30 is a high load shoring system that provides a fast, efficient and versatile supporting structure. The simplicity of the coupling of strong vertical Standards joined together by Horizontal Bracing Frames enables towers to be easily and safely erected.

  • Page 8: Safety Information

    The illustrations in these assembly configurations are minimum guidelines only. The combined use of the POWERSHORE 30 system with equipment from other suppliers may entail performance issues and therefore requires a design check and/or verification by Acrow Engineering or a qualified experienced engineer.

    Single Leg Props: When Acrow Powershore 30 is used as a single leg prop the boundary conditions at the top & bottom of the prop are considered as being restrained. The chart on page 19 provides working load capacities for prop...

  • Page 15: Summary Of Load Charts

    In the top unrestrained condition (ie. case 1) the stability of the load to be supported by Acrow Powershore 30 must be considered to ensure that it does not have adverse effect on the load capacity of the Acrow Powershore 30 towers. Generally, overall height is measured from top to bottom of the tower including adjustable bases.
