As the name says, these ropeway have motor. In relation to the mode of transport of wood, of skidders are distinguished by the fact that wood is raised off the ground. In most ropeway motor is used for traction in one direction, either cargo, or wagon. In the opposite direction used the force of gravity.
Wissen ropeway
Used to collect technical round timber, has two ropes that are open. Tow rope is used to collect wood from the side, the left and right onto the carrier rope, then for lifting and finally a tow rope carrier.
Ropeway has a motor and winch on a sled. The engine is a petrol, volume 12 to 15 kW. Rope tow is the diameter of 8-12 mm, a length of about 2000 m. Rope carrier has a diameter of 22-24 mm, a length of about 2200 m. Mass rope carrier is 2 kg /m. necessar slope for movement gravity is minimum 15% and maximum practiced up to 100% (45°).
Rope carrier is tightened by force from 8000 to 11000 daN. Duration rope corresponds to the volume of wood more than 60 000 m3. Ropeway route is a straight line, following the route if there are conditions and needs, is parallel to the previous. The distance between the two routes is up to 100 m. When transporting wood rope carrier, moving the wagon called ” the cat”. Wagon has a 4 wheels in the line, on the ball bearings. Significant device to the ropeway is blocker. He is mounted on the place where the performing loading.
Weight of the cargo is about 1000 kg. Consumption of gasoline is about 0.75 l / m3 collected by wood. Work is organized by the brigade system, brigade should have 5 to 7 workers. One worker operated motor, two attaches logs, one worker detaches at the unloading station, a two to three workers perform sorting at the unloading station. Cable car is mainly a burden that falls under the influence of gravity, the speed of regulating towline. Empty wagon is being pulled up the hill by a motor. Between the upper and lower station sets telephone connection.
The speed limits are as follows: draw near under the supporting rope from 0.6 to 0.9 m/s, abseiling carrier rope from 6 to 10 m/s, and restore the wagon up the hill 2 or 3 m/s.
