1.0. SCOPE OF WORK

1.1 This specification specifies the user requirements for the purchasing of a new under

floor wheel lathe for Transnet Engineering in South Africa. Under floor wheel lathes

are used primarily for the profiling of rolling stock wheels while they remain fitted to

the vehicle.

1.2 It involves the purchase, installation and commissioning of a new under floor lathe

including a maintenance plan during the guarantee period.

1.3 The full design requirement for the foundation of the new under floor lathe is to be

provided.

1.4 The tenderer must indicate compliance to each item in the checklist in Appendix E and

submit it with the tender.

1.5 A shunting vehicle to be used to move locomotives in and around the under floor lathe

facility shall be supplied together with the under floor lathe. Such vehicles are

typically, but not necessarily, battery operated. The shunting vehicle shall have the

ability to be remote controlled to allow the lathe operator to accurately position

locomotives on the lathe. The shunting vehicle shall be interlocked with the lathe to

ensure that the two machines work together safely.

1.6 A shaving crusher and conveyor to transport crushed shaving out of the building shall

be supplied.

1.7 The purchased under floor lathe must have the following general capabilities:

1.7.1 Ability to verify calibration, and if necessary calibrate the measuring system in the

under floor lathe. This includes the supply of a suitable calibration (standard)

wheelset.

1.7.2 The under floor lathe must be able to accommodate a single "loose" wheelset or

wheelsets mounted to a locomotive. The lathe must be able to accommodate any

Transnet locomotive. The nominal rail gauge is 1065 mm. Axle load of up to 30 000

kg per axle should be accommodated. Locomotive details pertaining to wheel

profiling will be supplied upon request.

1.7.3 Reliable and accurate measurement of the wheel profile of both wheels on the

same wheelset, prior to and after profiling. A general measurement accuracy of

±0.05 mm or better is required.

1.7.4 Calculate the necessary machining based on the pre-machining measurements

and the specific locomotive type constraints.


1.7.5 Store and report all wheelset geometric measurements including pre-machining,

post-machining and calibration verification measurements.

1.7.6 All measurement data must be stored on a PC with windows 10 operating systems

in a SQL lite database from where data can be exported to an excel file.
