Common 10 Ton Overhead Crane Accidents
Lifting accidents refer to heavy objects (including spreaders, hoisting weights or booms) falling, pinching, object hitting, crane tipping, etc. , electric shock and other accidents.
Serious injury accidents can cause heavy casualties or property damage.
According to incomplete statistics, in special types of work where accidents occur frequently, the number of lifting accidents is high, the consequences of the accidents are serious, and the proportion of serious injuries and deaths is large, which has attracted great attention from relevant parties.
From a safety point of view, unlike the fixed operation method of one person and one machine in a small range, the function of the crane is to lift heavy objects into the space for loading and unloading.
In order to meet the needs of the operation, the hoisting machinery needs to have a special structural form, so that there are many dangerous factors in the crane and the hoisting operation method itself. In summary, lifting operations have the following characteristics:
1. Hanging objects have high potential energy
The materials to be transported are large in weight (generally weighing up to one ton), various in variety, and in various shapes (including pieces, bulk materials, liquids, solid-liquid mixtures, etc.), and the process of lifting and transporting heavy objects in high altitude Suspension exercise.
2. Lifting is a combination of multiple movements
The four major mechanisms form a multi-dimensional movement, the overall movement of tall metal structures, a large number of complex structures, different shapes, and different movements. The movable parts with variable speed form the characteristics of many and scattered dangerous points of the lifting machinery, which increases the difficulty of safety protection.
3. Wide range of work
The metal structure spans the workshop or work site, and is higher than other equipment, facilities and construction crowds. The crane can move partly or as a whole within a large range, which increases the scope of danger.
4. Multi-person group work
During the lifting operation of the 10 ton bridge crane, the procedure is that the cableman on the ground binds the hanging objects and hooks; the lifting driver manipulates the crane to lift the materials, runs through the space according to the command of the ground, and puts the hanging objects at the designated position to unhook them. , Unloading. Every lifting cycle must be completed by the cooperation of multiple people. No matter which link goes wrong, accidents may happen.
5. The working conditions are complex and changeable
In the workshop, there are many ground equipment and concentrated personnel; outdoors, it is affected by climate, meteorological conditions and site restrictions, especially mobile cranes are also affected by multiple factors such as terrain and surrounding environment.
In short, the lifting of heavy objects in space, the multi-mechanism combined movement of the 10 ton overhead crane, the mobility of the huge metal structure, and the large-scale and multi-link group operation make the safety of lifting operations particularly prominent.
