10 essential common sense for crane operations. Today we will take a look at the first five:
1. Find a safe position
It is not safe to work or walk directly under hanging objects because the objects may fall on you. In hoisting operations, it is very dangerous to stand under the boom, under the hanging object, in the area before the hoisted object is lifted, in the triangular area of the guide pulley steel rope, around the fast rope, standing on the inclined hook or the direction of the guide pulley force. parts. Therefore, the position of the staff is very important. Not only should they pay attention to it at all times, but they also need to remind each other and check and implement to prevent accidents.
2. Correctly understand the safety factor of lifting rigging
During hoisting operations, workers do not have a correct understanding of the safety factors of slings and often use them as a basis, resulting in overweight operations always being in a dangerous state.
3. Demolition operations must be foreseeable for various situations encountered
Appraisal of the weight of objects, thoroughness of cutting, increased load due to extrusion of dismantled parts, forcible lifting of connecting parts without inspection, etc.
4. Eliminate erroneous operations
Hoisting operations are different from many construction projects. They involve a large area and often use different units and different types of cranes. Factors such as differences in daily operating habits, performance, and command signals can easily lead to misoperation, so be particularly cautious.
5. Tie the lifted objects firmly
During high-altitude hoisting and dismantling, “lock” rather than “pocket” should be used for the hoisted objects; “pad” measures should be taken for the sharp edges and corners of the hoisted objects.
