2. Design

3. Identification of Components

Mabey’s Mass 10 is a modular system intended for use in temporary works such as Propping, Needling and Wall Forms. 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 10 system, further details can be found in the Mass 10 bro-chures and Technical Data Sheet (TDSM10) available on request from any Mabey Depot.

Note: Mabey are suppliers of hire equipment and when hiring Mass 10 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 with Mabey labour. The Installation service also includes provision of contract lifts, lift supervisor and appointed person duties. Please contact your Mabey Representative for further details.

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 10.

Mabey offer a design service through our regional engineering teams. A comprehensive Technical Data Sheet (TDSM10) is available for those wishing to undertake or check designs.

The safe working loads shown in the table below are for props used in a vertical application only and include a safety factor of 2.0.

For props a recommended straightness tolerance is given below, indicated by Max Offset Dim (mm). Should the prop fall outside the range shown, the components should be checked for local damage.

Prop End-to-Prop End and Prop End-to-Pivot End (LF002) bolted joints require 6 No. M12x40 bolts. The bolted joint between Prop End-to-Spherical End requires 4 No. M12x40 bolts.

Intermediate lengths can be obtained by adding other prop lengths or in some cases an adjustable end fitting can be fixed at each end.

Allowance to be made for elastic shortening of the assembled Prop = 0.07mm/tonne/metre.

Careful consideration should ALWAYS be given to bracing which may be required for the reasons given below. A com-bination 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.

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).

6.2.1 Stability of Propping During Installation

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).

6.2.2 Stability of a Propping System Which Needs to Provide Lateral Stability as Well as Support Vertical Loading

Provided the props are subsequently released and removed one at a time then it may not be necessary to brace the props during dismantling.

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 overall. ALWAYS INCLUDE AN OVERALL STABILITY CHECK IN THE DESIGN.

For further information on bracing, please contact a Mabey Engineer for assistance.

6.3.2 Using Header Beam Connector 6.3.3 Using Location and Clamp Plates

The Header Beam Connector (LF007) fits on top of a vertical Mass 10 Prop, providing a connection to the hori-zontal Needle Beam, as shown. The Header Beam Con-nector (LF007) is free to move through 360°, allowing the needle to be located at any position on top of the Prop. The Washer (LF008) does not clamp tight, but holds the Connector Plate captive to the Prop end plate. If required the Header Beam Connector (LF007) can be positively fixed to the vertical Prop by using 4No. M12 bolts, (see section 5.2 for details).

The Spherical End Adjustable (LF003) (which provides 5° max tilt) fits on top of a vertical Mass 10 Prop, provid-ing a connection to a horizontal Mass 10 Prop used as a header beam. The Needle Beam is then clamped to the Header Beam using the Location Plate (LF004), which is positioned on top of the Header Beam at 90°, (see section 5.2 for details).

Mabey are suppliers of hire equipment and when hiring Mass 25 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 recommend that a typical erection crew should comprise a foreman and three opera-tives, competent in basic structural steel erection and a small mobile crane with a supervisor.

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 Sys-tem of Work, Method Statements and installation with Mabey labour. The Installation 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.

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 10. They should not be used to replace any existing safety procedures. It is recommended that all personnel using Mass 10 familiarise themselves with these guidelines.

• 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 Section 6.2) and have a Holding Down Baseplate (LF004) 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 suitable method statement.• If in any doubt always consult a Mabey Engineer and never take risks.• It is advised that all such work should be carried out by suitably trained and experienced personnel.
