132HC Mast SectionAfter the New Year, the tower crane opened to pay attention to
1. Whether there is water in the structure or frost heaving deformation, after the winter, more or less some snow, and the structure of the tower crane is not completely sealed, so some standard sections, components, cracks and other places will have some water. It is important to pay attention to these areas during inspection and clean them up as soon as they are found, because the water will not only corrode the metal itself, but also cause more damage when it expands or contracts, as the seasons change and temperatures rise It's GonNa be exponentially more corrosive.

2, the lubricating oil, after a longer period of time, before the start of the inspection must be on the reducer in the lubricating oil carefully check, observe whether there is water and dust and other sundry. Not only to check the oil quality and oil quantity, but also to confirm the oil label, the need for seasonal replacement must be replaced in time to avoid the normal use of imaging equipment. 3. Steel wire rope, steel wire rope plays an irreplaceable important role in tower crane, must strictly implement the steel wire rope scrap standard, for reaching scrap condition steel wire rope must immediately scrap and replace. As a result of a period of downtime, must pay attention to wire rope has no corrosion, surface impurities, etc. . In the inspection also pay attention to the wire rope associated with the components, such as drum, rope, pulley, rope card anti-off slot device. In addition, pay attention to the lubrication of wire rope, only good lubrication to ensure the life of wire rope and safe use. 4. Electrical system, before restarting the wire rope must ensure the independence of its power supply, and ensure that a machine, a brake, a leak, for can not be used. During the inspection of the electrical system, we should focus on checking whether there is water, dust, sundries, etc. in the distribution box, whether there is any cable, damage and insulation, sealing of the motor itself and the junction box, protection circuit, major parts, etc. Make sure it's sensitive, reliable, safe and effective. 5. Safety Devices, wire rope safety devices are particularly important for safe production, and all safety devices must be opened and inspected before being restarted to ensure that they are free of water and dust and can function properly All safety devices must be tested and verified before they can be put into use.
