Look at these very heavy logs

What is that   (I can see it is carrying the chainsaw, but does it have a name and some discussion here on the FF that can be linked ).  Appears the saw is perpendicular to the grain in the log, and I've often wondered if the chainsaw mills don't usually have a slight angle to the cut, of something like 10-15° ?
Curious here. 

That would be a Logosol M7 chainsawmill.  Just do a search on the forum here or Google it.  Its sort of like a "state of the art" Alaskan.  The frame holds small logs while the frame also holds the chainsaw on an incorporated rail and is pulled along by a small hand winch rather than having to push it through the log.  When the log is too heavy to sit on the frame, the entire mill is inverted on top of the log and still accomplishes the basic job of breaking down the log.

Thanks Jim
I didn't recognize it hanging upside down.

jkj,
Is there an info sticker on the drivers door post or end of the door ? It may give you such info as GVWR ( Gross Vehicle Weight Rating )  which is the maximum the loaded truck should weigh. It may also give you Axel Weight Ratings for the front and rear axels. If you know the empty weight of the truck, you can subtract that from the GVRW to get an idea of the useful load. For towing, look for the CVWR or GCVWR. This is the max total weight of truck and trailer.
One more thing to check on when hauling heavy loads. Look at the sidewalls of your tires and check out their weight ratings and the air pressure required to carry that weight. I have seen tires with a total capacity of 10,000 lbs on a trailer rated for 14,000 lbs. That is a good way to blow out a tire! The same thing applies to tires on a truck. Really important on the rear tires as they get the lions share of any load in the trucks bed.
If there is no sticker or data plate, you may try talking to the service dept of the dealership. The front of the service manuals normally have the info to decode the VIN. They could give you an idea of the spring ratings and the weight class of the truck. They may even be able to order a replacement Owners Manual for the truck.

what VA-Sawyer said is very important.  I know of one blowout in a pickup with a gooseneck trailer towing a 6200lb load that had a rear tire blow out at 70mph.  the tire was load range C, i'm pretty sure that's why it blew....

luckily nobody got hurt in that incident, but one can't be too careful.

I don't know when it started but my 92 pu has a sticker in the glove box with the weights. Problem is mine has all #'s readable except the 1st. Some day i may make the time to find out.
