Common knowledge about the use of grab cranes? In the usual construction process, in order to improve work efficiency and save manpower and material resources, different types of grab cranes are often used, among which bridge cranes are more commonly used. Let's analyze this in detail.
As a type of bridge crane, it is widely used in factories, warehouses, docks, and open storage yards. To ensure the safety of operators and equipment, there are some matters that need special attention.
1. Regular safety technical inspections should be conducted, and problems should be resolved in a timely manner. Relevant technical personnel are required to be proficient in equipment maintenance knowledge, operate carefully, and should not use one crane to push another crane, nor should two pieces of equipment collide with each other.
2. Under certain special circumstances, grab cranes are not allowed to lift, such as poor signals, people on the lifted object, insecure binding, overloaded components, flammable or explosive materials, overflowing liquid items, and wire ropes that do not meet safety usage requirements, etc.
3. It has two mechanisms: the main hook and the auxiliary hook. However, it should be noted that they cannot rise or fall simultaneously unless there are special circumstances. For lifting objects less than 50% of the rated lifting capacity, both mechanisms are allowed to operate simultaneously; for objects greater than 50%, only one mechanism can operate.
4. When there are problems with the lifting brake of the equipment, heavy objects cannot be lifted. Additionally, the limit switch and interlock protection device should be checked regularly. If working with live electricity, safety protection measures must be in place, and a dedicated person should supervise.
