What is a manual winch

<p>A <a href="https://www.snowavesproducts.com/hand-winches" rel="noopener noreferrer" target="_blank">manual winch</a> is a machine with a vertically installed winch drum that can be wound under power without storing the rope. It also refers to a winch whose axis of rotation is perpendicular to the deck. It is a self-protection and traction device for vehicles and ships. It can be used in snow , Marshes, deserts, beaches, muddy mountain roads and other harsh environments for self-rescue and rescue, and under other conditions, can be used to clear obstacles, drag items, install facilities and other operations. It is a military police, petroleum, hydrology, environmental protection, forestry, Indispensable safety devices for transportation, public security, border defense, fire protection and other outdoor sports.</p><p><br></p><p><strong>Principle of manual winch</strong></p><p>Simply put, the internal working mechanism of the manual winch is: the electric power from the car first drives the motor, and then the motor drives the drum to rotate, and the drum drives the driving shaft, and the driving shaft drives the planetary gears, thereby generating a strong torque. Then, the torque is transmitted back to the drum, which drives the winch. There is a clutch between the motor and the reducer, which can be switched by a handle. The brake unit is inside the drum, and when the noose is tightened, the drum is automatically locked.</p><p>In actual use, some auxiliary items are essential for the safe and smooth use of the winch, such as gloves can safely protect the hands. In addition, if you want to fix the winch to a tree, you also need a strap, a u-shaped lifting eye and a tight wire pulley. The strap is used to fix the fulcrum. The ideal length is 1.5 meters to 2 meters; u-shaped lifting ears can connect the hook with the strap and the winch. Therefore, it is best to prepare several sizes of lifting lugs; when using two-wire or three-wire to change the direction of dragging, a tight wire pulley is required.</p><p><br></p><p><strong>Features of manual winches</strong></p><p>1. The traction force of the winch is set in pounds, which can be converted into tons or kilograms through conversion. It is best to choose a high-pound winch, because the weight of trapped vehicles is often much higher than the weight of daily vehicles. Do not pull objects that exceed the traction force of the winch.</p><p><br></p><p>2. The more the number of turns of the steel cable of the winch on the reel, the smaller the pulling force of the outer ring. The winch with a long spool can reduce the number of winding turns to increase the traction of the outer ring. For the same winch, the use of shorter steel cables is more traction than the outer ring of longer steel cables.</p><p><br></p><p><strong>Use range of manual winch</strong></p><p>Manual winches can perform vehicle self-rescue in muddy mountain roads and other harsh environments, and may perform obstacle clearance, tow items, manual winch installation facilities and other operations under other conditions. They are military police, petroleum, hydrology, environmental protection, forestry, transportation, and public security. , Border control manual winch, fire protection and other indispensable safety devices for outdoor sports</p>
