Technical Maintenance Support Job No: 20BCE2033 Your ref: 818 33 Beaver Street Geraldton, WA 6530

Aft: Mr Geoff Udy

Dear Geoff,

Project: 5t Light Vehicle Transport Frame

Design Report

Background

Technical Maintenance Support (TMS) have requested Blacktop Consulting Engineers (BCE) to design check and certify a frame used to transport light vehicles. It is the intention that the vehicle will be driven onto the transport frame which will then be lifted by forklift onto the tray of a truck where it will be transported to site. It is intended that the largest vehicle used on the transport frame is a Toyota Landcruiser which has a maximum Gross Vehicle Mass (GVM) of approximately 3.4t.

Structural Form

The transport frame is shown on TMS Drawing No TM-CC-01 Rev A provided in Appendix A. The transport frame is approximately 4.5m x 2m wide. The frame is fabricated from 150UC30 beams supporting 100x5x6 RHS secondary members. The fork tine slippers are spaced at 1500mm c/c and fabricated from 250x150x6 RHS members welded between 150UC30 primary beams. The 150UC30 beams have a 250mm long section of the web cut out for the fork tines in four locations. The ramp is constructed from 6mm checker plate which is fully welded to the top of the frame. The vehicle wheels will be chocked with four-wheel stops.

Design Standards

The transport frame has been checked in accordance with the National Transport Commission Load Restraint Guide and current Australian Design Standards AS/NZS1170.0:2002 Structural design actions, AS/NZS1170.1:2002 Structural design actions, AS4100-1998 Steel structures and AS/NZS2640:1994 Portable ramps for vehicles. The Light Vehicle transport frame has been checked to support the following loads:

1. A maximum dual axle light vehicle mass of 5t Working Load Limit (WLL) with a 2.5t maximum individual axle load.

Assumptions

The loading of the vehicle onto the transport frame will be made when the transport frame is supported by a concrete slab or flat compacted gravel surface and not by the forklift. The loaded transport frame will then be lifted by a suitably rated forklift by inserting the forks the full depth into the 250RHS slippers to ensure that both 150UC37 beams are supported by the fork tines. The frame shall be attached to the forklift during transport by suitably rated chain fixed around the RHS slippers. The design completed by BCE, which considers the stopping restraint loads required by the National Transport Commission Load Restraint Guide, requires the frame to be orientated frame long axis parallel to the long axis of the truck bed. When in transit the transport frame and vehicle will be secured to the truck in accordance with the National Transport Commission Load Restraint Guide. Information on the lashing requirements to secure the load in accordance with the Load Restraint Guide are provided in the Recommendations section below.

Results

The transport frame shown on TMS Drawing No TM-CC-01 Rev A provided in Appendix A will be adequate for strength and serviceability for a 5t WLL with a maximum 2.5t individual axle load in accordance with the National Transport Commission Load Restraint Guide and current Australian Design Standards with the following provisions:

1. The 6mm steel checker plate ramp floor shall be increased to 8mm steel checker plate which is fully welded to the supporting steel frame.

2. All new Universal Column (UC) sections shall be fabricated from hot rolled Grade 300PLUS steel sections. All new Rectangular Hollow Sections (RHS) shall be fabricated from Onesteel Grade C350LO steel sections. All steel plate shall be fabricated from Onesteel Grade 250MPa hot rolled steel plate.

3. All welding is performed in accordance with welding notes for steelwork provided in Appendix B.

4. The stability of the forklift shall be confirmed against manufacturers recommendations prior to operating when lifting the approximate total combined rated mass of the transport frame of 6000kg at a 1000mm load centre (half-length of frame).

5. TMS shall provide BCE with final detail drawings for checking prior to fabrication.

Recommendations

Surface Treatment

It is recommended that the transport frame steelwork receive a surface treatment. A robust surface treatment for steelwork is provided in Appendix C.

Marking

It is recommended that the transport frame be marked permanently and legibly with letters and numerals not less than 100mm high in a colour contrasting with the background, with the Working Load Limit (WLL) expressed thus:

WORKING LOAD LIMIT (WLL) 5000kg

MAXIMUM INDIVIDUAL AXLE LOAD 2500KG

Load Restraint

The National Transport Commission: Load Restraint Guide outlines the guidelines and performance standards for the safe carriage of loads on road vehicles. The Load Restraint Guide can be found on the National Transport Commission website at http://www.ntc.qov.au/heav-vehicles/safetload restraint-guide/. When determining the required load restraint in accordance with the Load Restraint Guide the following should be considered:

• All loads shall be arranged on the vehicle in accordance with Section B 'Arranging Loads on Vehicles' of the Load Restraint Guide published by the National Transport Commission. The load must be positioned to maintain adequate stability, steering and braking, and not overload tyres and axles. The vehicle's axle loads resulting from the positioning of the load may be obtained by weighing or calculation. The axle loads depend on the position of the centre of mass of the load. Positioning of the load and load restraint devices is beyond the scope of this report.

• The performance standard as outlined in Section F of Part 2 of the Load Restraint Code shall be satisfied which requires that the load should not move or become dislodged from the vehicle. To achieve this, the load restraint system must be capable of withstanding the forces that would result if the laden vehicle were subjected to each of the following separately:

0.8 'g' deceleration in a forward direction 0.5 'g' deceleration in a rearward direction 0.5 'g' acceleration in a lateral direction And to 0.2 'g' acceleration relative to the load in a vertical direction Tie Down Straps

By clamping the 5000kg load and the self-weight of the transport frame against the truck or trailer body structure with tie down straps the load will be restrained. Section F of the Load Restraint Guide states that load tie down is designed by combining the normal force of the self-weight of the load in addition with the extra clamping force applied by the lashings. The preferred method of lashing is using suitably rated webbing straps or chains. The use of ropes is discouraged.

If a tie down lashing is not vertical between the load and the tie point, its effectiveness is reduced below 100%. This is called the tie-down 'angle effect' and is outlined in Section F 3.3 of Part 2 of the Load Restraint Guide. The normal force from the lashing is dependent on the lashing angle and the lashing tension.

This combined force is then multiplied by the coefficient of friction (p) to determine the lateral friction force. Friction force is the force exerted by the contact between two surfaces when an object either moves across it or tries to move across it. An example of how to calculate the required number of straps in accordance with the Load Restraint Guide is provided in Appendix D.

We trust that this meets with your requirements, however should you require any further assistance, please do not hesitate to contact the undersigned on (08) 9964 5459.

Yours faithfully

Lester Smith Engineering Manager Attached: Appendices A to E.

Appendix B: Welding.

1. All welds and welding procedures shall comply with ASI/ NZS 1554.1:2014 as follows: a. Welds shall be category SP. Electrodes for SP welds shall have a nominal tensile strength of 480MPa. b. Welding shall comply with AS/ NZS 1554.1:2014 as follows: • Unless otherwise noted all welds shall be fillet welds shall be: 6mm continuous for 12PL and less 8mm continuous for over 12PL to less than 20PL 10mm continuous for 20PL and over (Welds to apply to the thinnest plate in the connection). • Welds shall be continuous, full seal welds. • Butt welds shall be complete penetration welds UNO. • Where a joint is required, all edges of steel faces in contact shall be welded.
