Take a semi-automatic spreader as an example, which requires daily maintenance and lubrication.
At present, most of the lubrication methods used in container spreaders are manual lubrication methods. The manual lubrication method has at least the following disadvantages: (1) The spreader needs to be put down during manual lubrication, which affects the operation of the spreader; (2) When manual lubrication, the grease is easy to drip and pollute the environment; (3) Because the container spreader has a compact space , Manual operation is inconvenient; (4) There are many and scattered lubrication points on the container, resulting in long working hours and high labor intensity; (5) The manual refueling method is contrary to the current development direction of unmanned automated terminals.
For manual lubrication, the benefits of automatic lubrication are obvious. Extends the maintenance cycle of the spreader; reduces unnecessary downtime, and reduces the cost of spreader replacement and downtime. Due to the precise timing and quantitative lubrication, the wear of the parts is reduced, and the maintenance cost is correspondingly reduced.
The lubrication cycle starts from the oil pumping stage. The lubricating oil is pumped out from the oil storage tank, passes through the main lubrication line, reaches the distributor, and then ends when the pressure at the pressure switch reaches the preset value. In the oil pumping stage, the quantitative lubricator delivers a quantitative amount of lubricating oil to the lubrication point through the secondary lubrication line.
In order to ensure that the lubrication points of the spreader are adequately lubricated regularly and quantitatively, the complete automatic lubrication system is very complicated. In addition to the above-mentioned pumps, distributors, and oil injectors, it also includes a series of components such as control units, pressure switches, and signal lights. Let’s take a look at a few physical installation drawings of the on-site spreader.
