The evacuation of the car is associated with a certain complexity in winter, since due to the time the temperature with the sign minus is limited to the life of working personnel. When performing evacuation actions, the staff has to solve problems with resistance, and quite large, it consists of the fact that the car is rubbed on snow, and thanks to the resistance of rolling, etc. D. Another obstacle is a case when the direction of efforts and the direction of moving the car that is required to be pulled out does not match.
Experiments were even conducted in the process of which it turned out that if the evacuation passes through the ravine or the ditches of the main efforts increases by 1.5 times. If you lower the level of fastening of the cable, the angle that does not correspond to the direction of pulling out, and as a result, the level of maximum effort will decrease.
For example, if you pull a zil-151 car from a vertical slope from a ravine with a great depth of snow. And if with the help of the cable a tow is carried out to the back, then the amount of effort will be eight and three tons. And if the cable is fixed for the transverse device located on the frame, then the force is fourteen and five t.
When a car or trailer is pulled out of a vertical ravine, the car should move at an angle of 90 degrees to the longitudinal axis of the cuvette. This should be done so that the car does not slip through the inclined plane, which can lead to the fact that the car will overturn.
If a car is evacuated, which is stuck in the snow or on an ice crossing, it is most correct to pull the car in the direction that is the reverse of the one in which the car moved before building.
If the car has damaged chassis, you should install it on the trailer and start towing.
Когда осуществляется эвакуация транспорта, застрявшего и потерявшего проходимость или подлежащего эвакуации, очень понадобятся лебедки. When pulling out a car with a tractor, the block is attached to a non -moving item. The hook from the cable is attached to the tugboat in front of the pulled car. The cable should be an angle of at least 15 degrees to the car, otherwise it will be necessary to apply the block. If you use the winch, then make sure that the crankshaft of the engine rotate at a speed of 900-1000 rpm. Maximum 1350 revolutions.
To evacuate the car, do not use the winch cable, and turn on the back. We add that, since the efforts are changing sharply, because metals are prone to coldness at low temperature, there is the possibility of rupture of the cable or breakdown of the front hook tugboat. That’s why it is strictly forbidden to stand next to the cables or between them.
