According to the different driving force of winch
According to the different driving forces of winches, there are mainly the following six types: electric winch, which is the most common winch. The advantage of driving the winch by the vehicle's own power system is that it can basically be used normally in the case of dead fire (which is its greatest advantage that other winches can't match), especially in areas with plenty of water, and it is simple to install and can realize multi-position installation and rapid displacement. Disadvantages: it can't be used for a long time (due to the limitation of the vehicle's own power system, it is easy to get hot, etc. ), and most electric winches can provide a small driving force, which can only be exerted in one direction (they can only be pulled forward when installed in front of the vehicle and backward when installed in the rear). PTO winch, which takes the power output from the transfer case as the power take-off, has the advantages of continuously providing large pulling force, long single use time (no heating problem) and providing multi-directional pulling force (front, back or even left and right), and is the best choice for military vehicles or serious high-performance off-road vehicles. Disadvantages: engine power must be used, that is, when the engine cannot work due to water ingress and other reasons. ; The transfer case cannot be used when it loses its driving force in the winch direction. The hydraulic winch uses the power/power steering system of the vehicle as its power source and the power steering pump as its power source. Advantages: It is convenient to install. Because its external fixed part is basically universal, even in the field, the driving force is between electric and PTO winch, and the chance of high temperature is extremely rare. Disadvantages: Like PTO winch, the engine driving force must be used, that is, the engine must keep rotating, and once the power steering system fails, it cannot be used (in some off-road situations, the power steering system is easily damaged by the outside world). Wheel winch is a relatively new winch system, which is driven by axle. The principle is to use four of the six fixing screws of most off-road vehicle wheels to fix the winch. Advantages: the installation/disassembly is extremely simple (and the tire can be changed in one step), the weight is extremely light (lighter than any other winch, which will not bring fatal extra weight due to the front suspension), the price is cheap, and the front and rear tension can be provided at the same time. Disadvantages: As far as I know, the disadvantage is that its power point is the axle, so it is too low to be used in some cases, and engine power must be used. Electric winch
Manual winches driven by the longitudinal or circular motion of human hands usually have little pulling force due to human labor restrictions. The design and working principle of pneumatic winch are the same as those of hydraulic winch, but the power is changed from compressed liquid to compressed gas.
Winches vary according to their use.
Winches can be divided into: ATV winch, cross-country winch, truck winch, industrial winch and so on. According to their different uses; According to the characteristics of some industries, there are waterproof winches and explosion-proof winches.
