1.Overview of major hoisting machinery accidents
The crane has a large operating height and a wide coverage area, and can hoist various types of construction heavy objects. However, during actual operation, safety accidents are prone to occur. Safety accidents during the hoisting process will not only cause huge economic losses to the construction unit, but also cause irreparable damage to the lives and property of the construction workers. Accidents mainly include accidents involving damage to mechanical equipment; accidents involving short heavy ropes, decoupling of heavy objects, broken hooks, and broken booms; accidents involving the impact of external factors on the environment, etc.
2.Danger area analysis
a.Under high voltage wires
Crane work often needs to be carried out under high-voltage power lines, which is also one of the areas most prone to electric shock accidents. High-voltage wires have a long induction range. If the crane approaches this area, an electric shock accident may occur due to excessive induced current.
b.There is a safety hazard in the wire rope of the crane itself. During use, there was a slight breakage problem, and the hook was obviously deformed and loose. Heavy objects falling from high places may cause casualties and other problems.
c.Overload in actual hoisting operations. It is the lifting machinery operator's lack of safety awareness and lack of in-depth understanding of the weight of the sling or the object to be transferred before the transfer operation. Overloading can damage the sling, causing the sling to loosen or fall, causing heavy objects to fall from high places and causing casualties.
3.Meassure
a.Regularly check the electrical equipment of the crane to ensure that wires, plugs, etc. are in good contact, and to prevent aging and damage of wires.
b.Set up safety isolation fences or signs around the bridge or gantry crane, and strictly prohibit unauthorized personnel from approaching.
c.The construction contracting unit must strictly formulate a complete construction environment supervision and management mechanism, and conduct quality and safety management of the environment and lifting machinery based on the requirements of construction drawings;
d.Complete hoisting machinery maintenance mechanism. Since hoisting machinery is generally constructed in an open-air operating environment, it is prone to mechanical wear, low operating speed, short service life and many other problems. For this reason, it is necessary to carry out regular maintenance on the lifting machinery and improve the maintenance mechanism of the lifting machinery.
4.Summarize
In summary, Dingya Crane reminds you that during engineering construction, you must pay attention to the safety of the use of lifting machinery, take measures to prevent accidents, guide workers to gradually develop safety awareness, regularly organize workers to conduct safety knowledge and skills training, and effectively strengthen the safety awareness of workers. Safety supervision of heavy machinery and scientific and rational use of machinery and equipment.
The crane type should be selected taking into consideration the following points:
(1) The span, height, component weight and hoisting volume of the structure, etc.;
(2) Construction site conditions;
(3) The status of the existing lifting equipment of the enterprise and the region;
(4) Construction period requirements;
(5) Construction cost requirements.
The main reasons are as follows:
1.Cranes have a wide range of uses and many models. It is important to choose the appropriate bridge crane model according to different uses. Generally speaking, cranes can be basically divided into gantry cranes and bridge cranes. Generally speaking, gantry cranes are mostly used outdoors, and bridge cranes are mostly used indoors where walls are used as supports. For small lifting objects, you can choose a single-girder bridge (gantry) crane, and for heavy lifting objects, you can choose a double-girder bridge (gantry) crane.
2.Secondly, determine the crane model and tonnage: Each type of crane is divided into different models according to different lifting tonnage, functions, and grabbing heavy objects. For example, electric single-girder crane, single-girder gantry crane, beam bridge crane, etc.
3.In addition, you must determine the tonnage of goods that the crane you purchase will be able to lift. The tonnage cannot be too small, otherwise the crane will be easily overloaded, and if it is too large, it will easily increase the cost of purchasing the crane.
4.Determine the parameters of the crane again: The main parameters that need to be determined are: the span of the crane, which is the distance between the two outriggers; the lifting height of the crane, which is how high the heavy object needs to be lifted; the lifting capacity of the crane; the operating method of the crane, Generally, there are three operating methods for gantry cranes and bridge cranes: operating room operation, ground operation, remote control operation, etc.
The selection of cranes is not only related to the life of the crane, but also to equipment and personal safety, to the improvement of productivity, to energy conservation and emission reduction. Reasonable selection of cranes is very important. There are many crane manufacturers across the country, and their production levels vary from good to bad. Choosing a good crane manufacturer not only has good crane quality and low failure rate, but more importantly, it is less likely to cause safety accidents.
When you choose Dingya Crane, we will give you a specific plan for your specific project, saving the maximum cost while making more reasonable and efficient use of the crane!
