Maintenance Technology of Pivot Bearing on Portal Crane Boom

The position of pivot bearing on portal crane boom is relatively high,which makes it difficult to replace after damage,and the cost of renting large equipment is high and the maintenance time is long.In order to solve the problem,the method of replacing the pivot bearing on boom by making full use of existing conditions is introduced,and the causes of failure are analyzed.The progressive intelligent lubrication system is adopted by this method,which can solve the problem of over-lubrication and under-lubrication of lubrication points and reduce the damage rate of bearings.
