Is this equipment (pcw5000) prepared to skid logs with a diameter of around 3' 3'' (1 meter)? Is the diameter a restriction? As the weight restriction is around 2200 lb (1000 kg), if we want to skid a log with, let's say, 8000 lb (3635 kg), should we use two winches in parallel with one pulley at the load each? Can we do that or it is not advisable?
There is no restriction with diameter; however your logs are really big! The single line pull of the winch is 2200 lb (1000 kg); using a pulley it can pull 4400 lb (2200 kg). Using 2 winches in parallel is a possibility; using double pulleys will work as well but the speed will be reduced.
