We were founded in Y2015 at Singapore Industry Park, Suzhou, which is half hour`s car ride from Shanghai. In Y2019, we setup our HONGKONG office to support the growing of oversea business. We has established two business units to support different market strategy. Winch is our star product in off-road BU. We provide electric winch various from 2000lbs to 20000lbs, serve the industry for ATV/UTV, Jeep and truck. We also provide hydraulic winch from 10000lbs to 20000lbs, to serve the professional rescue industry. To ensure our winch always has best quality and best cost, we manufacture each key component by ourselves, like motor, gear box, rack, etc. Our manufacturing process covers Aluminum die-casting, punching, machining, CNC, and so on. Our quality department follows ISO 9 0 0 1 to control the process quality and the product quality. We provide our customer OEM/ODM service. The new design will be provided to support the new developed customer and protect the existing customer as well.
Our company utilized the on-line and off-line business model to enhance better customer service strategy. We have been striving to create value to our customer, supplier as well as our staff. Through us, we will live out the vision of glorifying God and benefiting people.
If you need to get something unstuck, lifted, or loaded, an electric winch can save a ton of back-breaking work.
The hardest part may be deciding which one you need.
Winches are commonly available with either a 12V DC or a 110V AC motor.
For fixed operations, such as a marine railway, a 110V winch works well because it can be plugged into an electrical outlet.
For portable applications or use with a vehicle as the anchor, a 12v Winch is the way to go. These units can be hard-wired into a vehicle or simply hooked up to a battery.
The next consideration is capacity-what weight rating should you look for? As a general rule, take the maximum load that you expect to winch and multiply it by 1.5. The weight rating is based on the first wrap of the cable around the drum. With each layer of cable, the pull capacity actually drops, so when in doubt, go larger.
Always stay well to the side of a working winch, and always drape a heavy jacket or tarp over the line. If a cable breaks, the heavy material will help absorb the energy of the taut cable as it snaps back, and reduce the chance of injury.
If a load outweighs your winch rating, remember those high school physics lessons about pulleys and mechanical advantage. You can double the pulling capacity by [doubling" the line. Run it through a Snatch Block attached to the object you`re moving and then back to a fixed object. Twice the capacity, however, equals half the pulling speed.

Ball valve basics
Ball valve and plug valve are of the same type of valve, and only its closure is a sphere, the sphere around the centerline of the valve body to rotate to achieve open, close a valve. Ball valve is mainly used in the pipeline to cut off, distribute and change the flow direction of the medium. Ball valve is widely used in recent years, a new type of valve, which has the following advantages: 1. Fluid resistance is small, the resistance coefficient and the same length of the pipe section. 2. Simple structure, small size, light weight. 3. Tight and reliable, the current ball valve sealing surface material widely used plastic, good sealing, vacuum system has also been widely used. 4. Easy to operate, quick opening and closing, as long as 90 ° rotation from full open to full close, easy to remote control. 5. Easy maintenance, ball valve structure is simple, the seals are generally active, demolition and replacement are more convenient. 6. In the fully open or fully closed, the ball and valve seat sealing surface and media isolation, the media will not cause erosion of the valve sealing surface. 7. Wide range of applications, the path from small to a few millimeters, up to a few meters, from high vacuum to high pressure can be applied. Ball valve has been widely used in petroleum, chemical, power generation, papermaking, atomic energy, aviation, rockets and other departments, as well as people's daily lives. Ball valve can be divided according to the structure: First, the floating ball valve Ball valve ball is floating, under medium pressure, the ball can produce a certain displacement and squeeze the sealing surface at the outlet end to ensure that the outlet seal. Floating ball valve structure is simple, good sealing, but the ball to withstand the load of the working medium all to the export seal, so to consider whether the seal material can withstand the working load of the ball medium. This structure is widely used in low pressure ball valve. Second, the fixed ball valve ball valve ball is fixed, does not produce pressure after the move. Fixed ball valve with a floating valve seat, subject to media pressure, the valve seat to move so that the ring is pressed on the ball in order to ensure the seal. Usually with the ball on the lower shaft equipped with bearings, operating torque is small, suitable for high pressure and large diameter of the valve. In order to reduce the operating torque of the ball valve and increase the reliability of the seal, in recent years there have been oil seal ball valves, both in the sealing surface injection of special lubricants to form a layer of oil film, which enhanced the tightness and reduced operating torque , More suitable for high pressure large diameter ball valve. Third, flexible ball valve Ball valve ball is flexible. Sphere and seat ring are made of metal materials, sealing a large pressure, relying on the pressure of the media itself has reached the seal requirements, must impose external forces. This valve is suitable for high temperature and pressure medium. Elastic ball is in the lower end of the ball wall to open a flexible groove, and to obtain flexibility. When closing the channel, the wedge-shaped head of the valve stem causes the ball to expand and press against the valve seat to seal. Before turning the sphere, the wedged head is released and the sphere then restores its original shape. This results in a small gap between the sphere and the seat, which can reduce the friction and operating torque of the sealing surface.
