The biggest advantage of mobile gantry is available full mobility, quick removal installation, small footprint, using a micro-car can be moved to another venue installation. Reasonable steel structure designed to withstand 500 ~ 5000KG weight, span up to 10 meters. Especially for the installation of workshop equipment, handling, debugging; handling, large engines and other auto repair shop lifting on the automobile goods. Small gantry crane with brake bearing caster can be moved on the ground, with the electric hoist or chain hoists and monorail support, Yichun gantry crane, lifting mechanization, can reduce manpower, reduce production operating costs, improve work efficiency. After the run-in period of use and maintenance crane factory, the general provisions of 60 hours of run-in period (some called a walk-in period), which is based on the technical characteristics of the early use of the crane and regulations. Run-in period is to ensure the normal operation of the crane, reducing the failure rate and prolong an important part of their life. First, the run-in period is characterized by: 1, wear faster because of the new machine parts processing, assembly and adjustment and other factors, the friction surface roughness, the smaller the area of ??contact with the surface, uneven surface pressure situation. The machine during operation, the concave and convex portions fit together parts of the surface friction, wear down to the metal debris, and as an abrasive, friction continued participation, yard gantry crane, but also accelerated the wear part mating surfaces. Therefore, likely to cause gantry crane hoists, run-in period parts (especially mating surface) of wear, wear speed. In this case, if the overload operation, it may lead damage, resulting in premature failure. 2, poor lubrication due to the small gap with the new assembly of parts, and due to assembly and other reasons, it is difficult to ensure uniformity with the gap, dock gantry crane, oil (fat) in the friction surface is not easy to form a uniform film, to prevent wear. Thereby reducing lubrication performance, resulting in the early parts of abnormal wear. It will cause serious friction with precision surface scratches or bite phenomenon, leading to failure.
