・Without requiring electric or air source, flange is lubricated with a infinitesimal quantity of oil that is discharged only when the crane is in operation.
With decreased friction resistance, it reduces flange wear and extends the wheel replacement interval (by 4-5 times for wheels or 2-3 times for rails).

・The oil feed can be automated in the crane maintenance operation.

・It leads to a reduction of abnormal noise.

・It facilitates inching motion of the crane to improve workability.

・It saves power consumption.

・With a body smaller than the F-type, this lubricator can be installed in a smaller space.
