1. Introduction Mabey’s Mass 50 is a modular system intended for use in temporary works such as Propping, Needling, dead shoring and facade retention. All standard components, as described in Section 3, have been designed to be used together to form the required schemes, they are not intended for other applications. This booklet provides basic information about the Mass 50 system, further details can be found in the Mass 50 brochures and Technical Data Sheet (TDSM50) available on request from any Mabey Depot. Note: Mabey are suppliers of hire equipment and when hiring Mass 50 the sole responsibility for adopting a Safe System of Work for all assembly, erection, dismantling and stability (both during erection and loading) of the equipment on site remains with the Client. Mabey do also provide a full design package, which includes a full design service including providing Safe System of Work, Method Statements and installation / dismantling with Mabey labour. The site service also includes provision of contract lifts, lift supervisor and appointed person duties. Please contact your Mabey Representative for further details.
2. Design No information on design is included in this booklet. Clients are strongly advised to ensure that a competent engineer is employed to provide a suitable design for schemes requiring the use of Mass 50. Mabey offer a design service through our regional engineering teams. A comprehensive Technical Data Sheet (TDSM50) is available for those wishing to undertake or check designs.
3. Identification of Components 3.1 Props The Prop Unit is designed to be used in Propping, Needling, dead shoring and facade retention schemes. They should not be used for other purposes without prior consultation with Mabey. 0

Please refer to the Technical Data Sheet (TDSM50) or contact Mabey for further details. Mabey recommend that all schemes / designs should have specific drawings showing the layouts and make-up of the Props and arrangements required. These schemes / designs should be approved by a competent engineer prior to any installation taking place. Note: Mabey do also provide a full design package, which includes a full design service including providing Safe System of Work, Method Statements and installation / dismantling with Mabey labour. The site service also includes provision of contract lifts, lift supervisor and appointed person duties. Please contact your Mabey Representative or a Mabey Engineer for further details.

6.1 Bracing (using Scaffold Bracing) Careful consideration should ALWAYS be given to bracing which may be required for the reasons given below. A combination of standard scaffold tube and various scaffolding fittings are normally used for the bracing. See section 5.2 for typical connection details. BS 5975: Code of Practice for Falsework sets out the requirements for lateral stability. 6.1.1 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 may only need to be braced to ensure stability during installation. In these cases the bracing needs to be designed for the lateral loadings to be expected during installation (e.g. wind). Structure being propped provides lateral stability
SC-SC
2No. TF018 or S3/GGC per connection
Props braced during installation
Bracing removed AFTER fixings installed at top and base
NB: Provided the props are subsequently released and removed one at a time then it may not be necessary to brace the props during dismantling. 6.1.2 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 2½% 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). Note: The overall stability of any propping system scheme needs to be taken into consideration during erection, usage and dismantling. A structure which has adequate internal bracing may still be unstable globally. ALWAYS INCLUDE AN OVERALL STABILITY CHECK IN THE DESIGN

6.2 Bracing (using Angle Bracing) Angle Braces when used with Web Bracing Cleats (TF001) allow Mass 50 Props to be built into standard sized frames and towers, see section 6.6 for details. Angle Braces can also be fixed to the Prop Flange by using a Flange Bracing Cleat (TF014), that this will produce non-modular panels unless special length Angle Braces are manufactured. Please refer to the Technical Data Sheet (TDSM50) or contact your Mabey Representative for further details.

6.5 Needling Certain Mass 50 components can be used together to create different arrangements that can be used for needling purposes. A typical example is shown below: 6.5.1 Typical Needling Arrangement Using Push Pull Props and Scaffold Tubes as Bracing Scaffold Clamps (TF018)
Grillage Beams
Raking Props (Push Pull Prop, as shown, or Plumbing Prop can be used) Props Scaffold Tubes Pivot End Adjustable (TF003) Holding down baseplate (TF012)
Note: Refer to Section 3.7 for further details on Plumbing Props. 6.5.2 Using Grillage Beam and Prop Raking Props (Push Pull Prop or Plumbing Prop) and/or bracing for stability as required
6.5.3 Using Spherical End and Header Beam Grillage Beam
Grillage Beam bolted to end of Prop
Wall
Prop used as header beam Adjustable Spherical End (TF021)
Prop
Adjustable Pivot End (TF003)
Typical Grillage Beam/Prop Arrangement A typical needling arrangement consists of a Grillage Beam bolted to a vertical Prop using 4No. M20x60 bolts braced with either Scaffold or Angle Bracing. Each vertical Prop is then individually supported by a Raking prop, which can be a Push Pull Prop or a Plumbing Prop, (see section 5 for connection details).
Typical Grillage Beam/Prop Arrangement Using Spherical End (TF021) The Adjustable Spherical End (TF021) (which provides 5° max tilt) fits on top of a vertical Mass 50 Prop, providing a connection to a horizontal Mass 50 Prop used as a header beam. The Grillage Beam is then bolted to the Header Beam using 4No. M20x50 bolts, which is positioned on top of the Header Beam at 90°, (see section 5 for connection details).

7. Usage and Safety Guidelines The following general guidelines are recommendations that should be kept in mind to ensure adequate safety is achieved. These guidelines are purely advisory and only state some of the many working practices or conditions that may arise using Mass 50. They should not be used to replace any existing safety procedures. It is recommended that all personnel using Mass 50 familiarise themselves with these guidelines. • Mabey strongly recommend that the use of Mass 50 is designed and any deviation from the design drawing must be approved by the engineer before continuing with the installation. • Ensure that all health and safety and regulations are adhered to. • Inspect all equipment before using and never try to use any damaged / deteriorated equipment. Bent Props should never be used. • Ensure that all bolted connections remain tight. • Ensure the verticality of the prop during erection / before loading using a spirit level or similar. • Be sure to inspect erected props before and immediately after load is applied. • Be sure to use the manufacturers recommended safe working loads relevant to the length of the Prop (a Technical Data Sheet is available on request). • To enable correct distribution of loads on props ensure that a solid footing is achieved and maintained. • Ensure that all props are loaded concentrically. • To ensure stability, all single vertical props should have sufficient bracing (see Sections 6.1, 6.2 and 6.3) and have a Holding Down Baseplate bolted to its base (BS 5975: Code of Practice for Falsework sets out the requirements for lateral stability). • In order to provide a safe system of work for erection / installation / dismantling, it will be necessary to create a suita- ble method statement / risk assessment. • If in any doubt always consult a Mabey Representative or Mabey Engineer and never take risks. • It is advised that all such work should be carried out by suitably trained and experienced personnel.
8. Erection and Dismantling Mabey are suppliers of hire equipment and when hiring Mass 50 the sole responsibility for adopting a Safe System of Work for all assembly, erection, dismantling and stability (both during erection, dismantling and loading) of the equipment on site remains with the Client. Mabey recommend that a typical erection crew should comprise a foreman and three operatives, competent in basic structural steel erection with a site manager in overall control of the workforce. Appropriate mechanical plant will be required. Clients are strongly advised to prepare a method statement for erection and dismantling before work commences and to ensure that all work is supervised and carried out by a suitably qualified and experienced personnel. The completed scheme should be inspected and signed off by the Temporary Work Coordinator or his delegated supervisor. Risks should be assessed, method statements and lift plans should be prepared for each application in accordance with current Health & Safety Legislation. Note: Mabey do also provide a full design package, which includes a full design service including providing Safe System of Work, Method Statements and installation / dismantling with Mabey labour. The site service also includes provision of contract lifts, lift supervisor and appointed person duties. Please contact your Mabey Representative or a Mabey Engineer for further details.
