Shovel

A shovel comprising:

• an undercarriage;
• an upper swing structure swingably attached to the undercarriage;
• an automatic greater mounted on the upper swing structure, the automatic greater including
• a lubricant pump;
• a plurality of distributors configured to distribute a lubricant discharged by the lubricant pump to a plurality of greasing points, the lubricant being a grease;
• and
• a selector valve placed between the lubricant pump and the plurality of distributors, the selector valve being configured to selectively connect one of the plurality of distributors to the lubricant pump;
• and
• a hardware processor configured to control the automatic greaser,
• wherein the hardware processor alternately achieves a non-greasing state that continues for a first set time and a greasing state that continues for a second set time whose length is fixed,
• the hardware processor determines a distribution ratio according to which the second set time is divided into a plurality of greasing times for feeding the grease to the plurality of distributors in the greasing state, based on a work load on each of the plurality of greasing points or an operation frequency of each of the plurality of greasing points, and selectively feeds the grease to the plurality of distributors according to respective greasing times allotted to the plurality of distributors within the second set time in the greasing state, the greasing times being allotted to the plurality of distributors according to the determined distribution ratio, and
• the hardware processor distributes the grease to the plurality of greasing points according to the greasing times allotted to the plurality of distributors according to the distribution ratio that is initially set in the greasing state, in response to determining that a value representing the work load or the operation frequency is less than a predetermined value in the non-greasing state immediately before the greasing state, and changes the distribution ratio and distributes the grease to the plurality of greasing points according to the greasing times allotted to the plurality of distributors according to the changed distribution ratio without changing the length of the second set time to increase an amount of grease fed to a greasing point among the plurality of greasing points in the greasing state, in response to determining that the value representing the work load on or the operation frequency of the greasing point is more than or equal to the predetermined value in the non-greasing state immediately before the greasing state.
