The steel plate lifting pliers are divided into horizontal pliers and vertical pliers, the safe working load of the horizontal pliers refers to the load of a pair of horizontal pliers, the lifting plate thickness refers to the thickness range of the steel plate lifting pliers, the actual opening degree of the steel plate lifting pliers should be greater than the thickness of the steel plate. The use and safety rules of steel plate lifters are as follows:

　　1. When the thickness of the lifting place exceeds the scope of application of the pliers, the steel plate lifting pliers should be replaced, and overload is strictly prohibited.

　　2, in actual use, there should be a gap between the steel plate and the ground, and the size of the gap should be slightly greater than the bottom thickness of the steel plate hoist. Manually move the tongue of the steel plate pliers to the large opening and clamp the transverse pliers on the steel plate when one side of the steel plate touches the inner side of the steel plate pliers. Before lifting, check that the center of gravity of the steel plate should be located on the center of the polygon formed by the two groups of lifting pliers. 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 position of the steel plate lifting pliers should be re-adjusted. Pay particular attention to the absence of beams, at this time the Angle between the steel plate and the horizontal plane shall not be greater than 5 reads, otherwise it must be re-installed.

　　3. Only one steel plate is allowed to be lifted at a time, and two layers of steel plates are not allowed to be lifted at the same time and other objects are placed on the steel plate.

　　4. During lifting operations, the steel plate pliers must be inserted to the end until the steel plate contacts the inner wall of the steel plate pliers.

　　5, during the lifting process, it is strictly prohibited to lift the steel plate by collision and impact.

　　6, the lifting process should be as smooth as possible, and it is strictly prohibited to stand or pass on the items below.

　　7, each time before and after use should be checked for abnormal conditions in each part, such as cracks in the welding seam of the clamp body, hole or shaft deformation and scratches on the rotating part, rust and tooth damage.

　　8. After the loss of the logo, it should be made up in time to avoid wrong use.

　　9. The storage place should prevent rust and damage to the paint surface of the steel plate hoist.

　　10. When not used for a long time, grease should be applied to each active part and paint the rest.
