Transverse steel plate lifting tongs are more common, and most of the lifting operations of large steel plates will use transverse steel plate lifting tongs, and a single steel plate lifting tongs can not play an effective role, more is to use four steel plate lifting tongs for lifting operations.

　　Four steel catchers will encounter a fixed pinch distribution problem when lifting steel plates, we all know that the main sling of the steel plate should be suspended as far as possible in the vertical position above the center of the steel plate, and then connected with the multi-limb chain rigging, and the steel catchers at the end of each chain rigging are fixed on one side of the steel plate.

　　However, for a slightly larger steel plate this way does not seem to work, the larger the steel plate, the greater the average distance of the steel plate pliers, the greater the distance naturally cannot guarantee the separation Angle of the chain rigging, which is easy to cause the risk of slipping, for this situation will generally choose a more secure way a beam auxiliary.

　　The connecting point of the main sling is the middle of the hanging beam, and there are hanging rings on both sides below the hanging beam, at this time, the chain rigging is grouped, and the two groups are fixed on the hanging ring of the hanging beam. Then the steel plate lifting pliers are fixed on both sides of the steel plate, through the assistance of the lifting beam, the length of the chain rigging is shortened, the Angle between them is also reduced, and the stability of the operation is increased.
