The single and double beam gantry crane is strictly prohibited to work under overload, inclined pulling and heavy objects. Adjust the upper and lower limit stop blocks before lifting objects. Please confirm whether the brake condition is reliable before using the single and double beam gantry crane.
Due to the influence of new machine parts processing, assembly and adjustment, the friction surface is rough, the contact area of the mating surface is small, and the pressure bearing condition of the surface is uneven. During the operation of the machine, the concave and convex parts of the part surface are inlaid with each other for friction, and the worn metal debris, as an abrasive, continues to participate in friction, which further accelerates the wear of the fitting surface of the part. Therefore, during the running in period, it is easy to cause the wear of parts (especially the mating surface), and the wear rate is fast. At this time, if the operation is overloaded, it may lead to damage and early failure.
In a word, the requirements for the use and maintenance of cranes during the running in period can be summarized as: strengthening training, reducing load, paying attention to inspection, and strengthening lubrication. As long as we pay attention to and implement the maintenance and repair of the crane during the running in period as required, we will reduce the occurrence of early failures, extend the service life, improve the operating efficiency, and make the machine bring you more benefits.
