The round steel lifting clamp is mainly used to lift the round steel. Due to its unique characteristics, the steel plate can be clamped to complete the lifting. In the course of use, the relative means of the hinges connecting the claws, the support plates, the tie rods and the small tie rods in the round steel lifting clamp are determined after the test and comparison by coordinate drawing. The relative position determines the direction of the force of the jaws and the stroke of the jaws.
When the object to be grasped is placed behind, the jaws should be disengaged from the heavy objects, so that the clamps are clamped when they are lifted. When the thin plate is lifted, the angle of rotation of the tie rod is large, the horizontal component force applied by the heavy arm is also large, and the grip of the claw is strong. When lifting the thick plate, although the angle of rotation of the tie rod is small, the horizontal component force applied by the heavy arm is small, but due to the leverage of the claw itself, a strong grip force is still generated for the heavy object.
In addition to lifting heavy objects, round steel lifting clamps can also be used for drawing work, such as pulling steel bars stuck in iron shells. Other angles, I-beams, etc. that are pulled out of the construction site are also applicable. In short, as long as the tongs can do what they can, it is very convenient.
The small hook on the tongs of the tongs can be used when the weight is not grasped and the jaws are in the open state. When the heavy objects are caught in the jaws, the small hooks are opened and the hoisting is performed upwards, that is, the work is carried out, after the lifting is completed, Hang the hook and the crane can lift the tongs without the need for manpower. When the heavy objects are placed behind the lifting, there is no squatting impact, and the tongs are in contact with the supporting surface with the heavy objects, and are gradually released and released gradually.
When the round steel lifting clamp is lifted, it can be lifted from horizontal to vertical, and the jaws are fully engaged. From the horizontal position to the vertical position, the claws gradually grasp the steel plate. When the round steel is in the vertical position, there is no danger of falling down, because the clamp will be grasped as long as it is over the center of gravity.
