What is the reason for the occurrence of oil leakage during the deceleration of the gantry crane? Below is a detailed introduction from the manufacturer of Shandong gantry cranes.

Due to the unreasonable design of the manufacturer, design defects such as the lack of specialized ventilation holes or too small ventilation holes during the design process can cause uneven pressure inside and outside the gearbox, resulting in leakage faults and ultimately leading to the leakage of lubricating oil from the gearbox. Due to improper maintenance by gantry crane operators or maintenance personnel during daily use, multiple internal blockages and higher internal pressure than external pressure may occur. At the same time, excessive oil volume and loose fasteners can also cause oil leakage between the two boxes due to loose joint surfaces.

It is also possible that the leakage is caused by poor sealing of the connection surface of the reducer during long-term use. The limited level of processing technology results in insufficient accuracy of the contact surface of the box, leading to poor sealing performance and oil leakage.

In order to effectively prevent oil leakage in the gearbox, manufacturers should improve their technological level and optimize their design plans: a ventilation device can be added to the oil filling hole cover to ensure smooth and balanced internal and external pressure. At the same time, the accuracy of the process between the joint surfaces of the two boxes should be improved during the design process to prevent oil leakage faults caused by loose contact surfaces. At the same time, maintenance and upkeep should be carried out during daily use, regularly checking whether the ventilation holes, oil levels, casing, fasteners, etc. are in normal condition.
