钢丝绳葫芦与环链葫芦都是主要的电动葫芦种类，前者体积小，自重轻品种规格多、操作简单、使用方便，后者比前者体积更小，重量更轻，两者最大的不同点就是后者把钢丝绳换成了链条。 Wire rope hoist and chain hoist are the main types of electric hoist, the former small volume, light weight specifications, the operation is simple, easy to use, more the latter than the former smaller volume, lighter weight, the biggest difference is the two the latter change wire rope to the chain. 一、体积不同 A, different volume 环链葫芦的取物缠绕装置是环链，链轮的转动是升降的关键，而环链在链轮上的缠绕方向可以随意设置，灵活度高，结构合理，所以体积较小，而钢丝绳葫芦，缠绕装置是钢丝绳，升降靠卷轴转动，要升到最大高度，钢丝绳需要在卷轴上缠绕至少3圈。这就导致卷筒长度要增加，高度增加，卷筒加长，设备的体积就会增加。所以一般同规格的钢丝绳葫芦是环链葫芦提及的几倍甚至十几倍。 Chain hoist fetch winding device is a link chain, sprocket wheel rotation is the key to the elevator, and chain in the direction of the winding on the sprocket can be arbitrarily set, high flexibility, reasonable structure, so the volume is small, and wire rope hoist, winding device is a steel wire rope, lifting rotation on a scroll, and will ascend to the maximum height, wire rope needs winding at least 3 rounds in a scroll. This leads to reel length to increase height increases, the reel to lengthen, the volume of equipment will increase. So generally with the specifications of the wire rope hoist chain hoist is mentioned several times or even dozens of times. 二、提升高度不同 Second, the hoisting height is different 钢丝绳葫芦提升重物靠的是缠绕只卷筒上的钢丝绳发生的弹性形变，卷筒直径越小，钢丝绳型变量越大，因为一侧承受压力，一侧承受的是拉力，为了让这两种力量不超过规定，卷筒直径需要增加。而环链葫芦，是链环铰接，环链主要承受拉力，为了减少链环之间及链环与链轮窝之间接触面的挤压强度，会将链轮制成窝状。由此可知，这两种同规格设备，前者卷筒直径大于后者链轮直径，所以同等高度的轨道，前者起升高度小于后者。 Wire rope hoist ascension weight by winding only the elastic deformation of wire rope on the drum, the drum, the smaller the diameter of wire rope type variable, because under pressure, the side of the side is under tension, in order to let the two forces do not exceed the prescribed, need to increase the drum diameter. And chain hoist, is hinged link, link chain mainly bear tension, in order to reduce the link between the chain and sprocket and litter of contact area between the compression strength, will be made, sprocket. Therefore, these two kinds of the same specification equipment, the former sprocket wheel diameter drum diameter greater than the latter, and so the orbit of the same height, the former hoisting height is less than the latter.
