A manual winch is a mechanical device with a vertically installed winch drum that can be wound but does not store ropes under power drive. It also refers to a winch with a rotating axis perpendicular to the deck. It is a self-protection and traction device for vehicles and ships, and can perform self rescue and rescue in harsh environments such as snow, swamps, deserts, beaches, muddy mountain roads, and other conditions. It can also perform operations such as clearing obstacles, dragging items, and installing facilities under other conditions. It is a military, police, petroleum Safety devices indispensable for hydrology, environmental protection, forestry, transportation, public security, border defense, firefighting, and other outdoor sports
1. The traction force of the winch is determined in pounds and can be converted into tons or kilograms through conversion. It is best to choose a winch with a high weight, as the weight of a trapped vehicle is often much higher than the weight of a daily vehicle. Do not tow objects that exceed the traction of the winch.
2. The more turns the steel cable of the winch wraps around the reel, the less tension the outer ring has. And a winch with a long winding shaft can reduce the number of winding turns to increase the traction of the outer ring. For the same winch, using shorter steel cables has a greater traction force on the outer ring than using longer steel cables.
Scope of use
Manual winches can be used for vehicle self rescue in harsh environments such as muddy mountain roads, and may perform operations such as clearing obstacles, dragging objects, and installing manual winch facilities under other conditions. They are essential safety devices for military police, petroleum, hydrology, environmental protection, forestry, transportation, public security, border defense, manual winches, fire prevention, and other outdoor sports
