What’re the use and maintenance of crane in run-in period(Part II)?
(2). crane use and maintenance in run-in period
1. because the gantry crane is of special vehicles, operators with certain operating and maintenance experience can operate the machine after receiving trainning, guide from 
manufacturers. product use and maintenance instruction is necessary materials for operators, related operating and maintenance should be in accordance with instruction
2. operating load in run-in period should be not more than 80% of rated load, arrange proper working load, avoid overheating in long time continuous work.
3. often observe instructions from instrument, if it is abnormal, stop the crane to clear the trouble immediately, before confirming the reason and clearing the trouble, stop working.
4. often check oil (water) level and quality of lubricating oil, hydraulic oil, cooling liquid, braking fluid and fuel oil and check the tightness of the machine. If the oil/water is short or too much, analyse the reason, meanwhile strengthen lubricating on each lubricating point, it is suggested to add lubricating grease on lubricating point per shift.
5. keep machine clean, adjust and tighten loosen spear parts in time, so that wearing parts seriously or loss of spear parts caused by loosen parts will not happen.
6. after the run-in period, make a mandatory service on the machine, pay more attention to check and adjustment, change oil or liquid.
to sum up, the demand on crane use and maintenance in run-in period should be: enhancing trainning, lightening load, paying attention to check and strengthening lubricating. Only we attach more importance to crane use and maintenance in run-in period and put it into practice, the failure rate in early time will be decreased, the crane will have a long service life, improve working efficiency , thus benefit users more.
