Under the epidemic situation, construction site construction has been postponed repeatedly, from February 10th to February 17th, and the latest part of the area stipulates that construction must not start earlier than March 16th, and the usual work tools are instantly rectified by the repeatedly delayed resumption time. The piles of iron goblet can grieve the owner and operator.
I want to say, do n’t worry if we are in the construction machinery industry, the epidemic situation will always pass, and the start of the project will start sooner or later. Even if we ca n’t start making money for a while, we ca n’t rest at home during this time, and we will learn the practical skills of excavator maintenance under the epidemic with the editors. After the start of work, how to disinfect the excavator, how to get the excavator into working state quickly after a long stoppage, how to protect the health of the operator, etc., we invite Shandong Lingong service experts to give you guidance. .
Site Construction
Bring your own tableware, keep a distance of 2 meters, disinfection & masks are indispensable
Human safety and health are always the most important. Many users are worried that the site staff is complicated, that they have collective meals, and collective accommodation. In this case, what methods are used to ensure that they are not infected by the virus? In addition, what should be paid attention to on-site construction? In this regard, Shandong Lingong, a service expert, gave opinions:
The equipment should be disinfected before entering the site, and all personnel entering the construction site should be registered, wear masks, and take body temperature.
When the site construction staff needs to communicate, try to use mobile devices, such as mobile phones or walkie-talkies, to communicate. When it is really necessary to communicate face to face, try to maintain a safe distance of more than 2 meters.
Drivers must be disinfected when changing shifts. The interior and exterior handles, handles, armrests, switches, grease guns, etc. of the driver's cab must be disinfected before operation.
Construction workers at the site should wear safety helmets, protective shoes, work clothes, gloves, and reflective workers at night. Wear a mask during the entire construction process. When you eat, it is recommended to bring your own meals, prohibit table meals. When you really need to eat in the cafeteria, you should stagger the meal time, avoid gathering meals, and stagger the dining positions, more than 2 meters apart.
Excavator Disinfection
84 Disinfection, ventilation and air conditioning
After talking about the things that the operator and service engineer need to pay attention to, let's talk about the device itself. Robots and service engineers deal with the most on the construction site is the excavator, do a good job of equipment disinfection, is also an important measure to ensure the safety and health of workers.
As with site construction, drivers should wear protective equipment such as masks and gloves. Disinfect key parts. The disinfection method is to wipe with 84 disinfectant solution at a ratio of 1: 100, and then wipe it with water again, and disinfect it once a day. Special reminder, alcohol is corrosive to the interior of the cab, it is recommended to use 84 disinfectant.
In addition to disinfection, the cab should be ventilated frequently. So be sure to open windows and air conditioners. If you are working indoors or in a dusty place, it is recommended to close the window to enable the internal circulation function. If you are working in an open site, it is recommended to open the window or use the external circulation function.
After-sales service articles
High standard + comprehensive protection
In addition to on-site construction personnel need to take protective measures, there is also a category of people who must also be vigilant. They are service engineers at the manufacturer, commonly known as after-sales. In order to ensure the progress of the construction and ensure that the equipment does not fall off the chain, the service engineer must be on call 24 hours a day and play the role of a firefighter at any time. They shuttle between the construction site and the site. They are highly mobile and belong to a group with a higher risk. For these service engineers, how do they protect themselves and provide services to users safely? Experts also mentioned the measures taken by Temporary Labor :
First of all, as a temporary labor service staff, you should have received temporary labor training on safe operation and maintenance, and passed the assessment before you can start work. Secondly, according to the requirements of service standardization, you must wear labor protection shoes and reflective vests, hard hats and goggles when you arrive at the customer's site to protect yourself. At the same time, the process of getting on and off the bus and maintenance should be carried out in accordance with the safety training instructions. Furthermore, when providing services to users, temporary service personnel should implement protective measures such as vehicle parking methods, parking locations, suspension maintenance signs, and dismantling of oil cylinders in accordance with service standardization requirements to avoid equipment injuries.
Finally, it is also a key reminder under the epidemic situation that service personnel will strictly follow personal safety protection, wear masks, timely disinfection, etc. In addition, entering and leaving the site will strictly follow the relevant requirements of Article 1 to provide technical support to customers.
Downtime maintenance articles
Stare at the indicator before, after, and after starting
Many users also have a confusion. After a long shutdown of the equipment, it is inevitable to thoroughly overhaul it before starting work to ensure that the equipment enters the best working state at the fastest speed.
Comprehensive inspection of the whole machine before startup
The overall appearance inspection ensures that all parts cannot be missing and the overall appearance is intact. Make sure that working equipment, chassis components, electrical systems, covers, etc. are not bumped and damaged. Ensure the integrity of all connections, fittings, and connectors without abnormal wear.
2. Vehicle-wide oil inspection
Check 5 oils and 2 liquids (engine oil, diesel, hydraulic oil, transmission oil, gear oil, brake fluid, antifreeze), and check three filters (air filter, machine filter, diesel filter). Dirty or water must be replaced before starting the vehicle. Check each lubricating point, and start up after quantitatively filling with new lubricant.
3.Check the hydraulic system
Check the tightness of each part, and check whether the appearance is worn or leaked. Check the specific cause or replace it if necessary. Check the connecting pipeline between each component for leaks and wear. Tighten or replace according to the situation. Check the appearance of all the cylinders, and whether the coating of the piston rod has fallen off, and maintain or replace it according to the situation.
4. Electrical inspection
Check the battery, observe the color of the electric eye, and measure the voltage with a multimeter. The color of the electric eye changes to white and the battery needs to be replaced. After the black is charged, it can be started again. Inspect all electrical appliances, relays, insurances, wiring, etc. for missing or worn out, and replace and repair as necessary.
5. Inspection of engine and chassis parts
Check the engine oil level and observe the color and smell of the engine oil. Check the diesel filter, drain the filter, and drain the diesel tank. Check the air filter. If it is dirty, blow high-pressure gas (inside and outside, no need to blow). If it is dirty or polluted, replace it.
In addition, the service expert also mentioned some precautions during startup, mainly judging abnormalities and indicators.
Start to start the device. At this time, you should observe two alarm symbols displayed on the dashboard, one is "oil pressure indicator light" and the other is "battery charge indicator light". Both alarm symbols are displayed in red alarm status, and the device key switch After reaching the "ON" position until before starting, the two alarm symbols are both on and off after starting the car. The above is the logical relationship between the two alarm lights. The principle is the sensor signal for detecting oil pressure and the detection. The battery status signal of the ECU pin whether the battery is charged is fed back to the computer version of the display.
If the outdoor temperature is lower than "0 degrees Celsius" (take Weichai engine as an example), there is another yellow "preheating" alarm symbol displayed before starting. This symbol is in the shape of a preheating wire and will continue to be displayed after the vehicle is started. After a while, the display time changes according to the outdoor temperature. The colder the outdoor temperature, the longer the warm-up time. The principle is the minimum value of both the water temperature sensor and the oil temperature sensor. If it is lower than the preheating opening temperature, the engine control computer will preheat the equipment.
