1, axial wear measurement of tower body slewing bearing

• Turn the crane to position A and use a plug gauge to measure the gap between point 1 and point 2;

• Turn the crane to position B and use a plug gauge to measure the gap between point 1 and point 2;

• Turn the crane to position C and use a plug gauge to measure the gap between point 1 and point 2;

•Fill in each measurement data into the table.

2, platform slewing bearing axial wear measurement

• Turn the crane to position A and use a plug gauge to measure the gap between point 1 and point 2;

• Turn the crane to position B and use a plug gauge to measure the gap between point 1 and point 2;

• Turn the crane to position C and use a plug gauge to measure the gap between point 1 and point 2;

• Turn the crane to position D and use a plug gauge to measure the gap between point 1 and point 2;

•Fill in each measurement data into the table.

3, slewing bearing raceway lubrication

Although the slewing bearing is lubricated during assembly, it cannot provide a sufficient amount of grease, so it must be re-lubricated while rotating before debugging. Re-grease the bearing rollers every 3 months.

4, slewing ring gear lubrication

The ring gear must always be adequately greased.

5, detecting slewing ring gear

After running for a long time, the gears will wear out. The allowable amount of gear wear depends on the use.

According to experience, the allowable wear amount of the slewing ring gear is the 0.1 module.

6, check sealing system

•Check all sealing systems

•Remove all contamination and dirt

•If the seal is damaged, it must be replaced or consult TTS-SCM's service department.

7, check connecting bolts

•The bolts have been pre-tightened with a hydraulic torque wrench or cylinder tensioner before use;

•During use, it is necessary to ensure that the bolts have sufficient pre-tightening force.
