An automatic lubrication system for lubricating an object is provided, which includes a lubricant container configured to contain a lubricant and including a rotatable shaft with a piston to dispense the lubricant from an output of the lubricant container, a housing with a coupling section coupled with the lubricant container, an electric motor configured to drive the rotatable shaft of the lubricant container during at least one lubrication action, such that at least a part of the lubricant is dispensable from the lubricant container during the at least one lubrication action, at least one capacitive sensor including at least one electrode, wherein the at least one capacitive sensor is arranged at a wall of the lubricant container and configured to provide at least one sensor signal indicative of a capacitance in a vicinity of the at least one electrode, and a control circuitry configured to determine, based on the at least one sensor signal of the at least one capacitive sensor, at least one lubrication parameter indicative of the at least one lubrication action.

An automatic lubricator for lubricating an object is provided. The lubricator includes a housing with a coupling section configured to couple with a lubricant container containing a lubricant, wherein the lubricant container comprises a rotatable shaft with a piston to dispense the lubricant from an output of the lubricant container. The lubricator further comprises an electric motor configured to drive the rotatable shaft of the lubricant container, such that at least a part of the lubricant is dispensable from the lubricant container, at least one sensor configured to provide a sensor signal indicative of at least one of a force exerted by the electric motor onto the rotatable shaft and a force exerted by the lubricant onto the container, and a control circuitry configured to determine a blockage of the output of the lubricant container based on the sensor signal of the at least one sensor.

An arrangement includes a shaft, a bearing, and a structure fixed to a housing. The shaft is rotatably mounted in the structure fixed to the housing by the bearing, and a first gap extends between the shaft and the structure fixed to the housing. The bearing and the first gap are connected to each other in a lubricant-conducting manner via a cavity. The structure fixed to the housing forms a first sump for lubricant, and the first sump is configured to collect lubricant dripping from the first gap.

An oil application device includes an oil supply member capable of selectively supplying oil to a first lateral surface and a second lateral surface of a flat wire. The oil supply member includes a first side surface and a second side surface. A part of the first side surface is a first application surface that is in contact with a part of the first lateral surface. Another part of the first side surface is a first non-application surface spaced apart from the first lateral surface. A part of the second side surface is a second application surface that is in contact with a part of the second lateral surface. Another part of the second side surface is a second non-application surface spaced apart from the second lateral surface.

A shovel includes an undercarriage, an upper swing structure swingably attached to the undercarriage, and an automatic greaser mounted on the upper swing structure. The automatic greaser is configured to individually change the amount of grease fed to a first greasing point among multiple greasing points and the amount of grease fed to a second greasing point among the multiple greasing points based on information on the multiple greasing points.
