Cause their the durability, versatility and safety, air winches are better than electric, diesel and hydraulic winches. Air winches can be manually operated with people standing beside it and the working way of them is that there are wire-ropes entangled with drum pulling the scraper pan to do the shuttle movement for scraping the stuff. Driven by the blade air motor and slowed by gears, they can rotate the drum to meet the working requirement by usage of braking the annular gear. With the high starting torque, it ensures winches starting with load and performing hoisting, lowering and stopping actions easily. And in addition to the powerful pulling capacity, the air compressor and winch share the same motor in order to save more energy to prolong the service life.More details about Air winch parts please contact RAMHOIST directly.
Owing to the copper power elements, they can keep a sensitive electric conductivity and transmission and the air compressor with automatic shut-off device can protect the air winches against over high pressure. Besides, the roller fairlead is split, reducing the resistance of fairlead during rope guiding. To be frank, the air winches greatly lower labor intensity and highly improve cable lifespan and working safety. Considering security, this winch is adopts dual automatic band brake and if needed, disc brake is available. What’ more, the air winches have a certain self-locking effect. That means when lifting the work, in the process of decentralization or lifting, according to the need, at random it can be stopped and the heavy objects do not have risk to fall.
Air winches are also called air driven winches, air operated winches, air winches hoist, air winching, air powered winches, remote control air winches, air tug winches, heavy duty pneumatic air winches with air cylinder brake, anti-explosion air pneumatic brake windless winches, newly developed automatic spooling winches and hand-operated type winches.Air winches are widely applied for drilling platform, marines, underground mining, engineering sites, platform of oilfield off-sea, islands, metal mine, coal mine, civil and building, dragging and pulling heavy cargoes, lifting loads in oil wells, construction projects, tanks, ships and boats. Furthermore, they can perform well under extremely working situations such as damp, inflammable environments, explosive and snowy conditions. Air winches are also especially fit for hauling and lifting drilling pipes on the second platforms or oilfields, and used in horizontal slushing or the slope slushing with an angle of little degrees.
Detailed description
1. Structure
Pneumatic air winches are air-powered energy, through the piston-type wind turbines and two sets of internal and two external gears which can drive vice-speed reduction mechanism to drive the drum to operate, in order to achieve its hoist purpose. Their main structure includes pneumatic motors, gear boxes, rollers and brakes. All the transmission parts use high-strength and high-quality alloy steel, after chemical heat treatment, parts has a long life. With the compact in size, the air winches are quite convenient to carry and store.
2. Control valve｜air distributing valve
Air winches are equipped with one foot valve. Operators should step the foot valve first to make the winch start working when in operation, secondly, you have to control it by handles. When you stop operation, you need to release the foot valve for stop winch working, and that will realize the longer life for the winch and air motor. When the handle is pushed to the starting position, the compressed air can go into the valve from the on-off valve, with the valve into the valve spool, making it turn. At the same time, the rotation of the valve spool will make compressed gas sent into the surrounding six cylinders. Due to the expansion of the compressed gas in the cylinder, thus it can drive the piston, connecting rod and crankshaft. When the piston is pushed to the ”bottom dead point”, the valve spool can also turn to the first exhaust position, after the expansion gas still with a certain pressure, that is, from the cylinder, passing through the valve exhaust channel, can come out of the body directly.
3. Hand brake
Brakes consist of steel belt, asbestos belt, the system frame, handle and adjustment screw and other major components. The steel strip is in the form of a ring with its inner wall riveted with asbestos band, surrounding the circumference of the brake drum, one end of winch is connected to a support frame and fixed to the base, the other end is riveted with internal thread, with adjustment screw on the support frame screwed together. When the handle is tightened in a clockwise direction, the strip can act as a brake, so that the running roller cannot be moved, on the other hand, if the handle is rotated in a counterclockwise direction, the brake can be released and the drum is free to rotate.
4. Air cylinder brake
The hand and air cylinder are specially designed in order to ensure the security during operation in case of the unexpected accidents or emergency occurring. With full strength and force, the double-braking air winches are competent enough to work under any extreme conditions or harsh weather, enabling starting with load for the high starting torque. Thanks to the brake system, the winches be automatically in brake when stops. And if needed, the dual automatic band brake or automatic disc brake is available for better operation.
5. Motor
With bidirectional electromagnetic braking, the DC series motor ensures the air winches can be installed in any direction. According to the motor voltage, the air compressor offers varied capacity. For instance, when the motor voltage is 12V or 24V, then the air compressor capacity is 72L/min and 95L/min respectively. Pneumatic motor is composed of on-off valve components and valve fittings and six connecting rods, pistons, cylinders and other main parts. The principle of piston type air motor’s running in basically similar to internal combustion engine.
6. Scraper winch wire rope
Air winches perform hoisting, lowering and stopping actions to the wire rope.
7. Gear box
Located between the air turbine and the drum, gearbox can obtain the power with the gas machine, through the two sets of deceleration wheel, and a clutch fixed to the spindle, it is passed the roller. Gearbox and the base are one, which is equipped with a gear rack and two gears, and one for the external gear and the other group for the internal gear, but all gears is fully enclosed in a gear box with certain oil level.
8. Pulley
9. Connector
The material selected for the connector and the area of the fracture are specified. If the main valve stops due to the lack of lubricant, and it continuously operate, the connector is immediately cut off, all parts will be in a pause state, and so this can avoid or reduce damage to other parts.
10. Drum｜pulling winch drum
The size of joystick’s pulling angle is related to the running sped of the drum so if the angle is beyond the limit, the drum will be able to rotate at full speed.
11. Sleeve
There are air distributing valve sleeves, crank inner sleeves, crank outer sleeves with connecting rod, connecting rod ring, piston and piston ring.
12. Some detailed photos
Others
1. According to the weight, air winches are divided into 3 ton air winches, 5 ton air winches, 10 ton air winches and other types.
2. In order to ensure the pneumatic winch works normally, operators have to make best use of it and prolong its working life. And it is quite important for users to install, operate and maintain it carefully. Moreover, customers have to read the manual book carefully before using the winch. But there is still one thing needed attention: Under complex outdoor situations, we can’t guarantee the safety of ourselves and our vehicles all the time.
3. Air winches include lots of figures such as working pressure, max pull force, max wire rope speed, air piston motor model, drum diameter, drum width, rope storage, air inlet size, dimension, weight and other parameters.
4. There are some recommended optional accessories such as tree strap, recovery board, quick connector, balance valve, shuttle valve, limiting switch, automatic band brakes, grooved, divided and extended length drum, drum guards, muffler, wireless remote control and other accessories. Also, there are special paint options of special colors, zinc rich primer, epoxy top coats and others.
5. There are still a lot of factors need to be taken into consideration while you are driving off-road vehicles under harsh environmental conditions. For instance, you may need a device for self-help in case of your vehicle stuck in a wetland, and you also have to make sure your vehicle tire is fully inflated so as to ensure safety.
6. Whether you're winching and airing up while off-roading, you could inflate a raft or air mattress or run a nail gun or impact wrench since it is the new way to get it done.
7. When lifting the weight, you must first push the clutch in the front of the drum. And when the joystick is pulled to the middle “parking” position, use the brakes to stop, which cannot achieve the purpose of braking.
8. Manipulation
When the trachea is connected, as long as clutch is pushed in the front of the cylinder, and the board is located in the pneumatic P end, the joystick will be able to run the winch and the joystick lever position can be divided into “left”, “middle”, “right” three parts, that is, it can make the drum get forward, stop or reverse three parts.
①When the lever is turned to the left, the drum’s running direction is positive.
②When the pull lever to the right, the drum can run in the opposite direction.
③When the joystick in the middle position, the drum can immediately stop.
9. When the air winches stopped running, if they need to plate roller, as long as it takes away the brake, the clutch can be free to run.
10. In order to coordinate the movement of the crankshaft, connecting rod and piston parts with the operation of the main valve, the connector connection is used between is used between the crankshaft and the main valve. The connector can not only make the crankshaft and the main valve operation consistent, and for the whole gas machine, it can still obtain a certain security protection.
11. Wind turbines speed, torque, power, and compressed air consumption and other technical performance parameters, are determined by the performance test of the gas.
