The above costs accounted for about 30% electromagnetic overhead crane of the overall cost. Metal structure according to its structure can be divided into the solid-web (the box structure made of steel plate, also known as) and lattice (generally made of steel, electric wire rope hoist manufacturer common root and lattice column), composed of the basic mechanical components of crane metal structure

Wrap rate mechanism, when the 2-for-4 magnification switching magnification is not in place, crane spare part did not pay attention to check, or no increase insurance sales, in lifting the pulley activity will suddenly drop, causing a major accident.The twisted rope play rope serious disorder, electric wire rope hoist manufacturers not immediately removed, forced to use.

The weight of the metal structure

single girder overhead crane Metal structure is a metal rolling steel (e.g., Angle steel, channel steel, i-steel, steel pipe, etc.) and steel plate as a basic building block, wall mount jib crane through the methods of welding, riveting, bolt connection, according to certain rules of connection, under gravity and load of the crane steel structure. The weight of the metal structure about accounts for 40% ~ 40% of the weight, heavy crane can reach

due to the inertia of the system could not produce coasting fall

Do not pay attention to maintenance from the weight of limiter does not regulate the limiter from the weight on the use of, electromagnetic overhead crane or even deliberately do not, or increase the limit value, so that from the weight of limiter should not restrict the protective effect.The lifting mechanism brake not adjusted too loose. When overweight high speed decentralization, over head cranes due to the inertia of the system could not produce coasting fall.

With the rapid development of China's urbanization

With the rapid development of China's urbanization, the single girder bridge cranes  with its strong scalability, large capacity characteristics, in terms of construction, cargo handling and other playing an increasingly large role. However, due to the risks involved in the field of mechanical and electrical construction cranes and aerial work operation, etc., crane supplier it also became a construction safety Each crane driver must pay attention to the matter
