How to Replace the Parts of Cranes?
Some operators think that the replacement of parts of gantry crane is very easy, only need to replace the damaged parts. As a matter of fact, if assembly is not suitable, the power can decrease, the fuel consumption increase, and start hardly. And maybe the machine is damaged. So replacements of parts have rules. ZZHZ give their advice.
1. When buy new parts, you must pay attention to the quality, and identify inferior parts. Checking the parts carefully to make sure the parts are rusty, crackled and deformed or not, and the size of surface meets the requirement or not.
2. The rust preventive coating of new parts should be cleared completely before using. Especially the precise couple for fear of making accidents
3. The transmutative products are not in common use because some diesel engine can produce the same type transmutative products, but they are not in common use.
4. Some parts should be replaced in pairs. Such as gear wheels, double sleeve roller chain in wheel box and cylinder sleeve.
5. The same model of standard parts and increased parts are not in common use. The manufacturer often produces the increased parts, therefore, when you buy the parts, you must identify the standard parts and the increased parts.
6. The model of the new parts and the old parts should be the same. Some operators replace the oil nozzles, they don’t pay attention to the model of it, and so they often buy the wrong valve couplings. Finally start hardly and the oil nozzle is stuck.
7. Pay attention to the directionality. Some parts have directionality. If you make a mistake, the start will become difficult and maybe the parts will be damaged.
