对于群吊电动葫芦我们并不陌生，它是一种低速环链电动葫芦，一种轻小起重机械，它具有起吊速度慢，机体质量轻，机件硬度高，磨损小的特点。群吊电动葫芦保留了手拉葫芦轻巧方便的特点,又改进了手拉葫芦人工操作,提升速度慢不足,它集电动葫芦和手拉葫芦的优点与一身,采用盘式制动电机做工作。那么如果群吊电动葫芦变形了，比如说：凹陷了，我们应该怎么办？
For group crane electric hoist, we are no stranger to it. It is a low speed chain hoist, a light and small lifting machinery. It has the characteristics of slow lifting speed, light body weight, high hardness and small wear. Group crane electric hoist preserves the characteristics of handy calabash, and improves the manual operation of manual hoist. It improves the speed slowly. It integrates the advantages of electric hoist and hand hoist, and uses disc brake motor to do the work. So if the group of electric hoists deformed, for example, a depression, what should we do?
首先我们需要搭建检修平台，检查群吊电动葫芦的损坏情况，其中的一些部件是否需要更换，然后根据一些具体的数据，调整现场，高强度构件在修理现场一般选择丝杠比较方便将丝杠放置于卷筒和外壳凹陷处间距的边缘，点动群吊电动葫芦控制手柄按钮，使卷筒逆时针转动，并逐渐送进丝杠，在卷筒的力矩作用下挤压丝杠，丝杠压迫外壳凹陷处，迫使凹陷处复原，待全部复原后，卷筒顺时针转动，退出丝杠。然后就测试是否运转正常，就可以工作，群吊电动葫芦产品“可退换说明”用户在购买群吊电动葫芦时会签订一份具有法律效力的购销合同，基本事宜参照合同处理，如遇群吊电动葫芦产品不合预期的情况下，我们提供一定的退换货服务。
First, we need to build a maintenance platform, check for damage hoisting electric hoist, whether some of these components need to be replaced, and then adjust the scene according to some concrete data, and the high strength components in the repair site will generally choose more convenient screw screw placed in the reel and the housing recess spacing the edge point hoisting electric hoist control handle button, the reel rotates counterclockwise, and gradually to the screw extrusion screw in torque drum, screw compression shell depression, depression forced restoration, all to be restored, the reel rotates clockwise, screw exit. Then test whether the normal operation, it can work, hoisting electric hoist product "return" the user will enter into a legally binding contract of purchase and sale in the purchase of electric hoist crane group, the basic issues with the contract processing, such as the case of hoisting electric hoist products are not up to expectations, we provide a return cargo service.
