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？ 　　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。 For group of crane electric hoist we are not strange, it is a kind of low speed chain electric hoist, a small light lifting machinery, it is lifting slowly, the body weight, high hardness, wear small features. Group of crane electric hoist to keep his hand chain hoist and convenient features, and improve the hand chain hoist manual operation, lack of speed is slow, it combines the advantages of electric hoist and chain with a suit, the disc brake motor work. So if the group of crane electric hoist deformation, such as: depression, what should we do? First of all we need to establish the platform maintenance, inspection group of crane electric hoist damage, whether some of these parts need to be replaced, and then according to some concrete data, adjust the scene and high strength components at the scene of the repair generally choose the screw is more convenient to screw placed on the edge of the drum and the shell cavity spacing, point DongQun crane electric hoist control handle button, make the drum counterclockwise rotation, and gradually to the screw, the roll torque under the action of extrusion screw, screw compression shell cavity, forcing cavity recovery, after being full recovery, drum clockwise rotation, from the screw. Then test whether working properly, it can be work, group of crane electric hoist products "can return instructions" users when they pinpointed crane electric hoist and sign a legally binding contract, basic issues with reference to the contract processing, in case of crane electric hoist products under the condition of not expected, we provide a certain amount of return service.
