Electric hoist way to promote and noise fault solutions

Electric  lift hoist  so that our country in this field and construction mechanization level of civilization has a greatly improved. From the early promotion of do not know, do not understand, do not use to this day in the cities of the construction industry has become an indispensable prerequisite equipment for the industry thought and understanding is a great improvement; domestic hoist manufacturing and leasing industry mushrooming development of the country's manufacturing enterprises no less than dozens of gourd, annual production had over 10,000, in the world, can also be called gourd production big country. Moreover, in the  wire rope hoist  structure, technology, technology has been greatly improved and enhanced. Meanwhile reach cantilever beam structure is the way, the stability of its force far less now widely used zipper-style lightweight and stable. Nevertheless, China's manufacturing industry in the technology gourd, structure, process and even the materials are to improve and enhance the space. Abnormal noise occurs in the control loop, making noises, typically contactor fails to deal with fault contactor maintenance, overhaul can not be replaced, treatment, self-noise elimination.hoist equipment Motor makes any abnormal noise, immediately stop, single-phase operation, the entire issue of regular motor suddenly strong suddenly weak hum; while bearing damage when near the bearing and shaft couplings errors, or when the motor slightly sweep chamber, when not accompanied by shrill voice. In short, the difference should be based on the noise, to find fault, for itemized repair and restore normal performance of the motor when the motor fault untreated,load chain prohibit the use of gourds. First determine reducer gearbox or bearing on whether to raise the oil prior to use, whether to use periodic replacement of oil, but also excessive wear or damage to the gears and bearings.
