POWERSHORE 30
1. Technical Specications
The Acrow POWERSHORE 30 is a high load shoring system that provides a fast, ecient 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.
Standards are joined together using a rigid full strength Standard Connector. Corner braces are attached
at apposing corners and alternated between each level to maintain squareness and rigidity of the tower
throughout its height.
Adjustable Bases at the bottom of the tower and Adjustable Bases with U-head attachments at the top
of the tower provide infinite height adjustment. These Adjustable Bases can be braced with a Bracing
Frame as required. The built in strength of each individual component contributes to construction of a
support tower capable of supporting leg load in excess of 300 kN based on tower and bracing frame
configuration.
Acrow POWERSHORE 30 Towers can be configured to support loads up to 1200 kN per tower.
The purpose of this document is to provide guidelines for design, safe handling, transport and installation
of the POWERSHORE 30 system.
The document also outlines the various components of the system and it features illustrations, working
load limits, typical assembly arrangements and safe transport and handling measures.
The information contained in this document is provided as a general guide only and does not replace
the need for the design to be reviewed and checked by a qualified person in the field of temporary works
design and installation, concrete, steel, building construction and services.
This material has been prepared in the context of relevant Australian Standards and the National
Construction Code (NCC). Users should make themselves aware of any recent changes to these
documents referred to therein and to local variations or requirements.
This document is NOT a substitute for site-specific Safe Operation Procedures. It is the Installation
Contractors responsibility to prepare safe work method statements and observe and comply with site
specific health and safety regulations, standards and policies.
Acrow has dedicated engineering services available for project assistance. We can provide design
support for clients to determine the best way to specify and document POWERSHORE 30. Our
technical experts can identify the most ecient temporary work design meeting project requirements,
specifications and installation process.
Should the users require any further information or guidance, they are encouraged to contact their local
Acrow branch.

The erection and application instructions contained in this manual are the recommended methods to be
used for POWERSHORE 30 products.
The technical function related instructions must be accurately followed to obtain the correct performance
of the product. Any deviation from the recommended usage will require a separate design and/or
verification by Acrow Engineering.
The safe use and application of the system must be in accordance with Australian Standard AS 3610
Formwork for Concrete, Occupational Health & Safety regulations, approved industry codes of practice
and relevant regulatory authority requirements.
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.
Hazard Identification/Risk Assessments for the erection and dismantling of the system are available
from Acrow branches. Site specific Hazard and Risk assessments may need to be generated for specific
projects.

Disclaimer
This safety information is to draw the user’s attention to possible musculoskeletal disorders as a result of
manual handling during assembly and dismantling of the POWERSHORE 30 system
It is recommended that users of the POWERSHORE 30 system employ and implement appropriate
procedures and control measures to eliminate or control any risk of Musculoskeletal disorder/injury while
handling.
Refer to the Code of Practice on manual handling published by local Workcover Authority or other
approved and recognised guidelines for correct and appropriate manual handling procedures.

3. Working Load Limits (WLL)
Geometrical Considerations
Towers:
Two dierent cases have been considered:
• Case 1: Top unrestrained, bottom restrained towers.
• Case 2: Top and bottom restrained towers.
For each case, dierent configurations have been checked depending on:
Plan dimension: 1.2 m x 1.2 m
• 1.8 m x 1.8 m
• 2.4 m x 2.4 m
• 3.0 m x 3.0 m
Height is measured from the top to bottom of the tower including adjustable bases. 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 eect 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. However
when stability of the load may be questionable, it would be appropriate to consider the overall height of
the tower to be from the top of unrestrained load to the bottom restrained point of the tower, in case 1 and
check load capacity from the chart for total height.
In the top & bottom restrained condition (ie. Case 2) the overall height of the tower would be the distance
between the restrained points.
Horizontal Bracing frames – the number of horizontal Bracing Frames depends on the tower height , the
maximum distance between Bracing Frames shall not exceed 2.4m:
Load charts on following pages provide working load capacities for towers from 4.6 metres to 14.8 metres
high and for all available plan configuration.
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
height range of 2.8m-10.0m including overall adjustable base extensions.
Tower Height Minimum Horizontal Bracing Frame Levels

5.8 - 8.8m 3

• 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 eect 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. However when stability of the load may be questionable, it would be

the top & bottom restrained condition (ie. Case 2) the overall height of the tower would be the distance
between the restrained points.
• Limit State Load Factor = 1.5
• Towers must be supported on suitably rigid footings to be designed by client.

3. Working Load Limits (WLL)
Example
Case: Top unrestrained, bottom restrained
PowerShore 30 Tower overall height (including jacks and unrestrained load) = 8.0m
Plan dimension: 1.80 x 2.40m
• Height 8.0m — 5.80 < 8.0m < 8.80m — 3 horizontal frame levels
• Top unrestrained
• Plan Dimension: 1.80m x 2.40m — 1.80 curve
From Load Chart on Page 3.6
Tower H = 7.60 m — W.L.L. = 142.5 kN
Tower H = 8.20 m — W.L.L. = 130.0 kN
Linear interpolation for overall height of tower & unrestrained load of 8.0m with tower plan
dimensions of 1.80 x 2.40 m:
Q =(142.5 - 130.0) x (8.2 - 8.0)
(8.2 - 7.6) + 130 = 134.2kN
