In the structural design, the tong body part of the vertical plate lifting clamps is usually made of low-alloy high-strength structural steel Q345B, and the hollow structure is implemented, which makes the finished product light and meets the strength requirements. Secondly, under the premise of ensuring the lightness, the relationship between the arm and the force arm of the tongs is reasonably distributed, and a suitable tooth shape is designed at the contact portion between the tongs and the support table.
Moreover, in the process of use, the jaws and the support table of the vertical plate lifting clamps can be as close as possible to the contact surface of the steel plate, so as to achieve the purpose of increasing the frictional force without damaging the steel plate. Finally, proper heat treatment of the jaws and the support table teeth greatly increases the service life of the jaws.
In actual operation, before the steel plate is inserted, the lifting plate needs to be pulled first, so that the vertical steel plate lifting clamps are opened and the two lifting hooks are respectively inserted and moved to the lifting steel plate, close to the two sides of the straight line through the center of gravity. Bottom surface. Pull the lifting plate through the lifting wire rope, and press the lifting plate tightly on the lifting hook to lift.
