钢丝绳电动葫芦在使用过程中，难免会因为使用不当或其他原因出现卡绳现象，一般情况下钢丝绳卡在滚筒与升降电机之间缝隙内，通常做法是拆下电机，然后取出钢丝绳即可，可是这种方法较为麻烦，费时费力。有时为了维持生产，将钢丝绳用气焊割掉，留下断钢丝绳极容易磨损滚筒和电机外壳，造成设备事故。下面介绍的方法就有效地解决了这个问题。 Wire rope electric hoist in use process, will inevitably because of improper use or for other reasons appear card rope phenomenon, usually rope card within the gap between roller and lifting motor, usually way is to remove the motor, and then take out the steel wire rope, but this method is more trouble, time-consuming. Sometimes in order to maintain production, the wire rope is cut off by the gas welding, leaving the wire rope easily worn down the roller and the motor casing, causing the equipment accident. The method described below effectively solves this problem. 　　在法兰盘内侧加焊一个挡圈，这样可防止钢丝绳因各种原因卡在上述部位，同时又不影响滚筒及电机的装配以及钢丝绳电动葫芦的使用性能。焊加一个挡圈不仅保证了电动葫芦的安全使用，也延长了设备的使用寿命。 In the inside of the flange plate welding a retaining ring, which can prevent the wire rope card for various reasons in the place, and shall not affect the roller and motor assembly and using performance of the wire rope electric hoist. Welding a stop ring not only guarantees the safe use of electric hoist, but also extends the service life of the equipment. 　　电动葫芦绳卡时使用要注意以下事项： The following items should be used when the electric hoist is used: 　　(1)钢丝绳葫芦卡子的大小要适合钢丝绳的粗细，U形环的内侧净距，要比钢丝绳直径大1-3mm，净距太大不易卡紧绳子。 (1) the size of the wire rope hoist clamp should be suitable for the thickness of the wire rope, u-shaped ring from the inside of the net, to 1-3 mm larger than diameter of wire rope, net from the tight rope too big not easy card. 　　(2)使用时把U形螺栓拧紧，直到钢丝绳被压扁1/3左右为止。由于钢丝绳在受力后产生变形，绳卡在钢丝绳受力后要进行第二次拧紧，以保证接头的牢靠。如需检查钢丝绳在受力后，绳卡是否滑动，可采取附加一安全绳卡来进行。 (2) tighten the u-bolt when used, until the wire is crushed by a third or so. Because of the deformation of the wire rope under the force, the rope will be tightened for the second time after the wire rope is under force. If the wire rope is to be inspected, the rope can be used to carry a safety rope card. 　　(3)绳卡之间的排列间距一般为钢丝绳直径的6-8倍左右，绳卡要一顺排列，将U形环部分卡在绳头一面，压板放在主绳一面。 Arrangement spacing between (3) the rope card generally is about six to eight times the diameter of the wire rope, the rope card to arrange YiShun, u-shaped ring part stuck in line head side, linking piece on the main line.
