Operation Guide For Hydraulic Winch Made In China

The hydraulic winch chassis adopts a box structure, and not all welds are welded continuously. The length and height of each chassis weld are different, and there are large individual differences in chassis rigidity. Some produce resonance effect, and the machine will be amplified if there is a little vibration noise; The chassis is welded by steel plates and does not have the function of shock absorption and noise elimination. If its natural frequency is close to the gear meshing frequency, it may cause a large common vibration of individual machines due to the weak vibration of gears, 

causing the noise value to rise. We have conducted tests for the above possibilities, but through three experiments, we found that the noise level is weakly related to chassis structure, stiffness, frequency and other factors, and the noise level is strongly related to moving parts. Therefore, the chassis design structure and manufacturing quality are not the reasons for the noise exceeding the standard.
