Sagar DCT or I forget their other name in Brantford had a set up for that a couple years ago not sure if they still do. Also Jim at Nationwide in Brantford has a trailer with a hitchhicker set up also I have seen running around.
Congil in Lambeth may be able to help too. They run b trains on brick mostly, but have onboard forkilfts. if it ties in with what they have, who knows.
