Canadian Non-Self Unloaders

[MarcE]

What kind of hours did the deckhands work on an unload?

[Lakercapt]

During the latter part of the ore unloading the deck, crew would go down the hold and sweep or shovel the last few pellets and dust into the clam bucket. When after washing out for the next cargo of grain we once used grain dust to dry up the last puddles but this was stopped when it was discovered there were grain bugs etc.in it and sawdust was used.

CSL provided this video of loading and unloading one of their straight deckers.

The one trip we carried grain on the Clarke in 72 we walked around the cargo holds with a mop and spread out the water so it would dry.

We used to use sawdust to dry up the puddles; I've heard of using leaf blowers, but never come across it yet

And leaf-blowers to help dry it out after the hose down and pump out.

If you are going to reload with the same cargo - no problem. New type of cargo, broom, shovel, bucket and rope to haul bucket up on deck and over the side.

Then possibly hosing out the cargo hold(s).

What always confused me about straight deckers is that, even after unloading, there is still residual cargo left in the bottom of the hold. How is this removed if there is not enough for a clamshell bucket?

They have used front end loaders dropped into the hold and guys with brooms and buckets for the last little bits left

These are built primarily to serve in the grain trade from Lake Superior down the St. Lawrence Seaway with a backhaul of iron ore to be unloaded primarily at Hamilton I believe. I don't know if there are any ore docks above the Welland Canal that can unload a straight decker any more. The time saving advantages of self-unloading equipment is offset to some degree over the loss of carrying capacity over longer distances. This is why the Ryerson was able to operate in the Seaway ore trade several years ago. In addition, Canadian fleets operate a mix of straight deckers and self-unloaders to meet their customer's needs.

Algoma at the Soo still has bridge cranes, but doubt if they've unloaded a gearless bulker in years.

Thanks garbear

See a lot of these and wonder how they are unloaded if Iron Ore or grain?

Iron ore is unloaded with bridge unloading rigs with clamshell buckets. Grain is unloaded with a grain leg that has a continuous chain of buckets that go around in the leg.

Unloading grain. Pretty much how it's unloaded.
