The horizontal lifting steel lifting clamp is light in weight and is made of low-alloy high-strength structural steel and heat-treated; the test load is 2 times the ultimate working load, and the breaking load is 4 times the ultimate working load; but the horizontal lifting steel lifting clamp is only suitable for Horizontal lifting of steel plates.
When the thickness of the hoisting station exceeds the applicable range of the horizontal lifting steel lifting clamp, the horizontal steel plate clamp shall be replaced, and overloading is strictly prohibited. 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. Manually remove the tongs of the transverse tongs to the maximum opening; clamp the transverse tongs on the steel plate, with the side of the steel plate contacting the inner side of the transverse tongs.
Before lifting, check that the center of gravity of the steel plate should be 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.
The horizontal lifting steel lifting clamp is used for 1-15 days, and you need to refuel it once. Make it energetic. To add oil lubrication to the rotating part of the bolt and the bearing and the threaded part of the pressure nut, then wipe the spherical chuck and the thread of the clamping bolt. When encountering debris that cannot be removed, replace the spherical chuck and clamping bolts in time to extend the service life.
