The MJ-01 lubrication system is intended for lubrication of the traveling wheels and rail tracks of overhead cranes. The system works on the principle of applying a lubricant mixture to the contact surfaces of the crane wheels and rails using compressed air. The mixture of lubricant and air is created in the mixer behind the lubricator, then it is distributed through a divider and nozzles without other mechanically moving parts to the designated place. The lubrication system is equipped with the function of cleaning the circuit with draft for long-term shutdown of the crane. It works completely automatically, while the lubrication cycle takes place exclusively during two-way movement (driving) of the crane according to the set mode.
