• Lifting steel for level of usage method and attention

1. The level of steel was being lifted, and to measure supporting the use the following plans to connect.
2.When the steel plate being lifted onto a short, only HORIZONTAL LIFTING CLAMP take four legs hoisting rigging = 45 º ½ of working load ; b = 30 º, 3/4 of working load.

Picture
3. Choosing the clamps must according to the weight of the steel and tickness, dtrictly forbidden using in overloading.
4. Actualy use, it should have a gap between steel plate and ground, the size of gap should be larger than the bttom thickness of the clamp.
5.The correctly lifting ways are(see the picture).
5.1. Lifting one steel plate once
Picture
5.2. The edge of the steel plate near the bottom of the clamp
5.3. Single or couple lifting clamp use one sling.
5.4. The steel plate should be horizotally during be lifting.

Operation instruction for vertical lifting:
1.Clamps in the form of vertical hoisting se figure:
2. Choosing the clamps must according to the weight of the steel and thickness,
is not even in the tongue clamp restrictions under the arm in the largest openings.
strictly forbidden using in overloading.
Promotion of vertical clamp so that the plate inserted into the vertical clamp shut up
3. Vertical clamp the handdle of the move to make even push pull arm lock, which
until the bottom, and then moved bakc to clamp the handle so that the vertical clamp
the bottom of the plate.

5. the right way of using Vertical clamps.

6. In the process of lifting, ste plate is strtctly prohibited of collision and impact.
7. Station is prohibited under load.
8. The surface on the steel plate dose not allow with any oil.
Oil drums clamps:
1.The right way using oil drum clamps:

Picture
2. Choosing the clamps must according to the weight of the oil drum, strictly prohibit using overloading.
3. During the process of lifting, oil drums is strictly prohibited of collision and impact.
4. The process of being lifted should be  as smooth as posibile, the following is strctly prohibited items in the  station or through the .
Rejected standards for clamp:
1. The jaw’s deformation achieve the opening of the original 5%.
2. The abrasion of the jaw up to 10% of the original size.
3. Clamp shaft bending capacity of the original lenght of 0.25%.
4. Clamp body was found  crack.
5. Clamp-severe was rustily, non-rotating flexibile.
