・The oil is transferred from the lubricated rail-side to the flange portion, protecting both rails and flange from friction.

・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. It reduces flange wear and extends the wheel replacement interval (by 4-5 times for wheels or 2-3 times for rails).

・A built-in FUJIMATIC PUMP enables a stable, tiny amount of oil discharge.

・As it lubricates both sides of the rail simultaneously, fewer points of installation are necessary, making maintenance easier.

・Since the lubricating wheels are designed to swing horizontally, they don't miss the lubricating points even the crane sways from side to side while in operation.
