can anyone ID this piece of Engineer kit?

[sapper740]

In my search to learn all things Engineer I came upon this interesting picture of R.C.E.'s at work clearing rubble in Caen. the picture was taken in August of 1944. There are two vehicles I haven't identified in the picture. One, the "Steam Shovel" I've seen pictures of but have never ID'ed fully. However, I have never seen before the small dump "truck" that it is loading. Has anyone seen this piece of kit before, know what it is, and if it was on any Canadian unit's T.O.& E.?
