Refers to the consumption standard of materials other than maintenance costs, energy and lubricating materials for port machinery during unit time. Such as tires, batteries, wire ropes, etc. Because the consumption time is relatively long, it is generally not suitable for monthly calculations, but the cost is relatively large, so the accumulation and statistics of this consumption cannot be ignored in daily management. (2) Unit of measurement 1 Electric machinery measures energy consumption in kilowatt-hours per thousand operating tons.
2 The internal combustion engine measures energy consumption in kilograms per thousand operating tons.
2. Maintenance Hours Fixed Maintenance Hours Quota refers to the number of standard hours required to complete the maintenance of a single piece of equipment.
3. Maintenance Cost The fixed maintenance cost quota refers to the consumption standard of low-value consumables, cleaning oils and some lubricating oils (greases) specified in the maintenance work of the equipment.
4. The operating consumption quota refers to the material consumption standard of the port machinery except the maintenance cost, energy and lubricating materials in the unit time period operation. Such as tires, batteries, wire ropes, etc. Because the consumption time is relatively long, it is generally not suitable for monthly calculations, but the cost is relatively large, so the accumulation and statistics of this consumption cannot be ignored in daily management.
5. Lubricating material consumption quota refers to the amount of lubricating oil consumed by the port machinery and equipment during the unit running time (excluding grease). Including the oil change and the amount of oil to be replenished, the equipment management department of each unit shall formulate the lubrication card as the data basis for the establishment of the quota by consulting the equipment manual and actual measurement.
(1) Calculate the formula for the annual oil change of a port machinery equipment:

The third chapter of the introduction of port crane transportation machinery and equipment management page change Q = ∑
n
i=1
Cimi
Where: n—the number of tanks;
i———a fuel tank (from 1 to n);
Ci——-the number of oil changes in the i-th tank all year round;
Mi———The oil quantity of the i-th tank.
