WZLR Sleepers

As we are planning on pouring the concrete floor slab this coming Friday it was thought best to have some new moulds ready for casting sleepers in case some concrete was left over.

The original mould was made to fit some smaller rail. It was decided to make a new set of moulds that fit the profile of the largest rail to be used on the system, and any rail smaller can be shimmed with steel plates to the correct gauge.

One mould finished, which incorporates two sleepers. A jig was also created for the welding of the M12 threaded bar to the 12mm rebar. This then gets pushed in the pre drilled holes in the mould and the concrete poured in.

If time can be found another pair will be made before Friday to make the most of any waste!
