How to remove and install crane wheel sets

Wheel set is one of the important crane accessories, due to the crane trolley running all the time on the crane wheel set wear, so in the use of frequent places, crane wheel set internal bearing damage, wheel set edge wear flat phenomenon are normal. Wheel set problems must be replaced in a timely manner, if not replaced in a timely manner, it is likely that accidents will occur in the process of use. Crane wheel set disassembly and installation of the sequence of step-by-step methods, for your reference.

A crane wheel set disassembly step-by-step method:

What should I pay attention to when dismantling the wheel set? What is the main order of replacement? The crane wheel set disassembly steps:

1、Remove the connecting bolt of the coupling at the end of the wheel shaft.

2. Remove the fastening bolts connecting the wheel set's angular bearing box to the end beam.

3、Use the crane lifting screw or jack to jack up the crane bridge, so that the wheel tread is about 10mm from the top surface of the track, pry the wheel set and pull it out along the track surface in order to remove and replace it.

4. Lift the pre-assembled, new active wheel set with the axle end gear coupling halves onto the crane track.

5、Push in the wheel set close to the mounting position, adjust the jack to lower the car slowly, thread in the fastening bolts and screw on the nuts to ensure safety.

6、Tighten the horizontal bolts appropriately and then tighten the vertical bolts accordingly, alternately. Tighten the wheels at the same time and check whether the wheels are flexible in rotation and check the horizontal and vertical deflection of the wheel installation.

7、Align the wheel end gear coupling half with the reducer driven shaft coupling half of the screw hole, put in the connecting bolt and tighten.

8、After everything is normal, drop the car body down.

Second, the crane wheel set installation steps and methods: 

Know the step-by-step method of wheel set disassembly, those how to install the new wheel set? Crane wheel set installation steps:

a, wheel set installation needs to be based on the keyway on the active shaft for fittings;

b, wheel set placed on the table pad, the active shaft needs to be vertically aligned with the car hole and keyway, and the mating surface for lubrication;;

c. The upper end of the active shaft is padded with a pressure block and aligned, and after opening the hydraulic press for test pressure, it is found that no problems will arise, and then gradually pressurised to the installation position prevails;

d, both ends of the shaft need to be fitted with bushings and a barrel cover with bolts needs to be fitted;

e. The inner ring of the bearing is heated by boiling oil and then fitted into the wheel shaft while it is still hot, and the angular bearing with the outer ring and spacer ring is fitted onto the shaft;

f, the inner ring of the fitted bearing needs to be snapped into a washer and fastened with a nut;

g. The two ends are fitted with a bored cover and a through cover respectively, and are reinforced and fastened.
