Due to the development of modern industrial economy, winches are widely used in various fields. Common types of winches are: pneumatic winch, electric winch and hydraulic winch, In the process of communicating with customers, we found that many customers have a relatively vague understanding of these three types of winches. In the purchase often confused, do not know which winch should be chosen, feature this article to share with you the difference between the three, if you still have questions, please fill in the contact form or call 18237125869 for inquiries.
The biggest difference between them is the driving method:
Pneumatic winch is the prime mover of compressed air as the working medium. It is a power device that converts pressure energy into mechanical energy by using the expansion of compressed gas. The electric winch is the lifting equipment driven by the motor, which needs to be connected to the power supply to work normally. The hydraulic winch is the lifting equipment driven by the hydraulic system, which needs electricity or diesel engine to provide power.
The working environment applicable to the three is very different:
Pneumatic winches are generally used in small Spaces or flammable, explosive, high-temperature and humid environments, such as construction, offshore and other Marine applications, as well as oil drilling platforms, pipeline laying, anchor handling and other oil industries. The electric winch is more suitable for lifting small and medium-sized items, such as tools, accessories, building materials, etc. The hydraulic winch is generally used for lifting heavy objects, such as steel, cement, machinery and equipment.
The load capacity of the three is different:
The load capacity of the pneumatic winch has a wide range of options, which can be customized according to customer requirements. The load capacity of the hydraulic winch is generally higher, usually between 1-100 tons, which can complete the lifting operation of larger weight. The load capacity of the electric winch is generally small, usually between 0.5-50 tons.
At present, our company can produce special winches such as logging winch, positioning winch, explosion-proof winch and manned pneumatic winch, which are not only suitable for explosion, high temperature and humid environment, but also suitable for desert, ocean, mine and polar cold environment. Products involved in shipbuilding, paper printing, mining, oil transportation, metallurgical manufacturing, chemical industry, aerospace and other industries, used in rubber and plastic machinery, pneumatic crane and winch, mining machinery, oil drilling platform, submarine pipeline ship, steel and other metallurgical production lines.
Why choose pneumatic winch?
The pneumatic winch is ideal for use in construction, offshore and marine applications and is suitable for operating in potentially explosive, hot, humid environments such as the drill floor of a rig, pipeline platform and a blowout preventer platform without generating sparks.
As the driving device of the main hoisting equipment, the pneumatic winch has been widely used in the oil industry such as oil drilling platform, pipeline laying, anchor loading and unloading, and has been related to the safe use and production of the entire oil equipment.

Pneumatic winch advantages:
1. Suitable for harsh work occasions, it can work in flammable, explosive gas, high temperature environment, wet or dry environment, and is not affected by the harsh environment of field operation, and is not affected by mechanical vibration;
2. Compared with the electric winch, it is smaller in size, lighter in weight, easy to move and fast to install;
3. The output power range and speed range of the winch is wide, the output power of the air motor is small to several hundred watts, large to tens of thousands of watts, the speed can be from zero to 2500r/min or higher, as long as the opening degree of the air flow section of the distribution valve is adjusted to control the flow of compressed gas can adjust the output power and speed of the motor;
4. It can use the existing gas source of well sites, mines and other working places, with better economic benefits;
5. The control gas path of the winch has overload protection effect, which will not burn due to overload and fatigue use. After overload protection is started, the pneumatic winch will reduce the output speed or stop, and resume normal operation immediately after the overload is eliminated;
6. With high starting output torque, it can be started directly with full load and stop quickly;
7. The output power range and speed range of the piston air motor used in the air winch are wide. As long as the intake and exhaust directions are switched through the air distribution valve, the fast conversion of the winch forward and reverse can be realized.
Pneumatic winch purchase precautions
The selection and purchase of pneumatic winches need to be considered according to the specific working environment, operating conditions and requirements. In general, the pneumatic winch needs to have the right load capacity, rotation speed, installation method, protective measures and other characteristics in order to meet the needs of the actual work. In addition, the maintenance and maintenance of the pneumatic winch is also very critical, regular inspection and cleaning of the gas path, lubricants and wearing parts, etc., can effectively extend the service life and stability of the pneumatic winch.
