What is the difference between a wire rope and a chain electric gourd?
volume Because of the link chain electric hoist fetch winding device is a link chain, drive chain hoist is by the rotation of the sprocket, chain wheel axial size is only part of the chain width 1.6 times the width. Chain and sprocket winding Angle of the bag is not greater than 270 °. The wire rope electric gourd is made of wire rope, which is driven by the rotation of the drum. At least three loops of wire rope are wrapped around the drum, which is the maximum height of the lift. The length of the drum when the hook reaches the upper limit is the main factor determining the volume of the wire rope. Wire rope electric hoist drum volume is greater than the whole chain electric hoist, if the hoisting height increases, the drum will lengthen, wire rope electric hoist volume than the same specification chain electric hoist a few times or even dozens of times.
Hoisting height Wire rope electric hoist wire rope winding on the drum, produce elastic deformation, drum side is under pressure, its corresponding face by tension, drum diameter is smaller, the greater the deformation of wire rope, wire rope corresponding surface pressure, the greater the tension. In order for this force to not exceed the allowable stress of the wire rope, the diameter of the drum should be larger, so that the deformation of the wire rope should not be too big. For this reason, the design specification requires that the drum diameter of the electric gourd should not be less than 20 times the diameter of the wire rope. The link between the ring chain and the ring chain is articulated by the link, and the chain is mainly pulled by pull. In order to reduce the link between the chain and sprocket and litter of contact area between the compression strength, general chain electric hoist chain made of five or six litter, lifting weight and lifting speed is lesser also have made into four sockets. Because of the above reason, the rope wheel on the wire rope and the hook is much larger than the sprocket diameter on the link chain and the hook. In this way, the distance between the hook spacing of the chain electric hoist is smaller than that of the wire rope. In other words, the lifting height of an electric hoist with the same high track chain is greater than the lifting height of the wire rope.
Running distance Operation type wire rope electric hoist axis and wire rope electric hoist of the orbits of the car and the center line of parallel, chain electric hoist axis and 90 ° to the orbit of the centerline can install and use. This way, in the same condition, the same track length condition, the chain electric hoist is larger than the wire rope electric gourd. Even HH axis is parallel to the center line of the orbit of the installation, because of the link chain electric hoist axial size is small, its running distance from wire rope electric hoist is much greater. When the wire rope electric gourd rises high, its drum is longer, so the operating distance effect is greater.
?the accuracy When hoisting wire rope electric hoist, because the wire rope on the drum arranged along the axial winding, therefore, hook will produce horizontal displacement along the axis of the electric hoist. The higher the height, the more winding the wire rope in the drum, the larger the amount of displacement. However, the loop chain electric gourd will rise up and down the chain of lead in the loop chain, and the hook can be accurately positioned.
A ton of chain electric gourd is more suitable for processing plants in Beijing.I hope my answer will help you.
