Shanghai Yan brand homegrown, focus on producing high-quality products and export to Europe and America, wholesale and retail, quality assurance, and affordable. Structural principle chain hoists lifting device: a combination of speed reducer and chain pulley block with reverse brake check. Chain hoists is to get a line to match the load traction by means of leverage through the human lever handle, a clamp body rotation movement of the load acting on the inside, driving load operation. First start lifting motor, the starting weight rise appropriate height, and then start the motor to run heavy transport to the specified location, run the car at the lower edge of the walking beam single beam. Using a motor-driven trolley running on both sides of the wheels when walking. Since the walking speed is relatively small, so running the car in general does not have a brake mechanism. Run the car when walking, in order to prevent heavy decline in the lifting mechanism is provided an electromagnetic brake. Braking relies on spring pressure of the inner and outer disk compression, and friction clutch principle is similar to suck the electromagnet is energized when released after leaving the outer disk, external disk release. Electromagnetic brake circuit and lifting the motor circuit in parallel, so as long as a start hoisting motors, electromagnetic brake is released, the upper weights, lower lifting with ease; when the motor is turned off chain hoists price, the electromagnetic brakes are off, electromagnetic attraction disappears under pressure of the spring, and external disk tightly pressed, play a role in braking. Chain hoists when lifting objects beyond the rising limit position to prevent accidents caused by the general rise in the lower reel mounted stopper. When the load limit position up to the spot chain hoists, plate and limit switch contacts, turn off the power, stop the weight continued to rise. Limiter is to prevent the hanging Kwan rises above the limit position sometimes used, it is not often used.
