The steel plate handling clamps include two structures: horizontal and vertical. When using horizontal tongs, if the thickness of the hoisting area exceeds the applicable range of the horizontal tongs, the horizontal tongs should be replaced in time and should not be overloaded. In actual use, there should be a gap between the steel plate and the ground, and the gap should be slightly larger than the thickness of the bottom of the clamp.
When installing, the staff can manually remove the tongs of the transverse tongs steel handling pliers until the maximum opening, and the transverse tongs are stuck on the steel plate, with the side of the steel plate contacting the inner side of the transverse tongs. Note that it should be checked before lifting, the center of gravity of the steel plate should be located at the center of the polygons of the two sets of tongs. After lifting the steel plate, the steel plate should be horizontal. When the angle between the steel plate and the horizontal plane is greater than 7°, the horizontal clamp position should be re-adjusted. Pay particular attention to the situation where there is no beam. At this time, the angle between the steel plate and the horizontal plane should not exceed 5°, otherwise it must be reinstalled.
Keep in mind that when using steel plate handling clamps, it is important to pay attention to safety. Only one steel plate can be lifted in one lifting, and two steel plates should not be lifted at the same time or other objects placed on the steel plate.
