How to extend the life of gantry crane

       Girder  bridge gantry crane  rails on the ground through the support of two rigid legs or rigid - flexible leg, forming a yard across the railroad tracks or door frame, outside the main beam extends outside leg cantilever portion can be expanded operating area, gantry crane is sometimes made into single-leg semi-gantry cranes, loading bridges is designed for loading and unloading gantry cranes, supply stations, ports and other sectors of granular materials stacker reclaimer, which features a car speed large span (usually above), high productivity (up to 500-1000t / h) or higher container gantry survey was developed in the 1980s, the aircraft, is designed to carry container pile stack and loading and unloading  overhead gantry crane , such as unloading the container gantry crane.
    1, first make sure that the door cranes spend the run-in period, which is the basis for long life, whether it is new or overhauled small crane engine must be run according to the rules;
    2: gantry crane engine main fuel purity, such as diesel and gasoline purity is not good, make precise fit body wear, with the gap increasing, causing oil spill, drip, fuel pressure is reduced, the gap becomes larger, even cause oil blockage, cranes cavitation axle bush-burning and other serious fault;
    3, ground inspection work: that regular checks fastening positions due to diesel and gasoline engines the course of the shock and vibration loads uneven impact, bolts, nuts easy to loose. There are various parts of the adjustment bolts should be checked in order to avoid damage due to loose body's accident;
    4, commonly used and check regularly do when gantry crane engine maintenance work to make small  hoist gantry crane  operation is always maintained in good condition. To ground observation, ground inspection, found fault, and remove.
