Dongguan crane rental talk about the characteristics of mobile crane? According to the statistics, about 40% of the accidents caused by cranes renting mobile cranes in Dongguan caused overturned cranes to work, resulting in overturning. About 30% of the accidents were caused by the lack of strength of the crane boom, and 20% of accidents were caused by accidents. The damage caused by wire ropes and the rest are accidents caused by other factors. The hoisting capacity of the mobile cranes in Dongguan cranes is usually given in two forms: one is the lifting characteristic curve and the other is the lifting performance table. In the control room of the crane rental crane in Dongguan, the characteristic curve and lifting capacity table are given on the metal nameplate. The hoisting performance of the mobile crane crane in Dongguan is characterized by lifting torque. The lifting weight is limited by the boom amplitude, the amplitude is changed, and the rated lifting weight is changed accordingly. When the amplitude is small, the weight is large. When the amplitude is large, the charging amount is small. It's good to have an accident. Theoretically speaking, at a large range, the strength of the lifting boom is determined, overloading may cause the boom to be broken, and a strength curve of the boom is drawn according to the relationship between the strength and the amplitude of the boom. At a small amplitude, the lifting operation is performed. The main danger is that loss of stability causes the entire machine to overturn and the lifting weight is determined by the stability of the crane. According to the relationship between the stability and the amplitude of the crane, the crane rental in Dongguan depicts a crane stability curve. The envelope of the two curves is the lifting characteristic curve, which stipulates the large lifting weight of a safe lifting under a certain range. The characteristic curve of the crane rental crane in Dongguan is the operation basis for the lifting operation. According to the boom size of the crane, the lifting load is strictly controlled in the safety zone where the characteristic curve is limited, and the characteristic curve is also an important reference for lifting accident analysis. Based on the analysis of the accident, it is also necessary to comprehensively consider the inertia force caused by wind force, improper operation speed, changes in the supporting base of the leg, the elastic downward flexion at the arm end when the boom is too long, and the like. The actual overload effect brought by the small crane can be analyzed with the help of characteristic curves. Therefore, when the crane crane rental in Dongguan determines the working amplitude, arm length and lifting weight corresponding to the lifting weight characteristic curve of the crane, it is called the lifting capacity table. The performance table is more intuitive and convenient to use. The disadvantage is that the crane is The stepless performance value becomes a graded value, and it is difficult to accurately grasp the lifting characteristics. To ensure normal use during work, it is necessary to understand the hoisting characteristics of the crane and ensure its service life. Resources: Dongguan crane rental Runda crane rental
