The 4 "life saving skills" of the excavator in winter

[BONOVO]

Point one: Start

In winter, excavatorand other equipment often encounter trouble when starting, and it is easy to fail to catch fire. The following points can be effectively avoided:

1. Choose a battery with a large cold start current, and try to keep the battery fully charged.

2. Choose the right diesel, such as -35 diesel in the environment of more than ten degrees below zero, otherwise diesel will wax and lose fluidity. The same is true for the choice of oil, and the oil should be replaced in time according to the actual temperature.

3. In extremely cold environments (below minus 30 degrees Celsius), it is necessary to install cold start auxiliary devices in advance, such as the optional device of John Deere excavator"burning diesel coolant heater", which can effectively solve the difficult problem of starting at ultra-low temperatures.

There are two actions to avoid when booting is difficult:

Generate an open fire to heat the engine block. Not even at a distance. Because there are many exposed pipelines on the excavator, there will inevitably be leakage of oil on the pipeline, and the high temperature open flame may cause fire and burn down the equipment.

Let the coolant out and heat it up before pouring it back in. In this case, if the temperature of the cooling liquid after heating is too high and the machine temperature is too low, the huge temperature difference may cause local cracking of the cylinder block, and this damage is difficult to repair. If you have to do this, be sure to control the temperature.

Point two: Warm up

Not only do people need to warm up before exercise, so do excavator. After starting, there should be a preheating stage, that is, before the engine water temperature and hydraulic oil temperature rise to 50 degrees, idle for a period of time, and then slow and slight operation, so that the equipment smoothly "into the state", and then start normal operation.

In addition, the construction site is prone to snow and ice in winter, so try to avoid excessive movement during operation, so as to avoid the danger of slipping.

Point three: Maintenance

excavatormaintenance, the most common is to change the oil. In winter, the engine oil must be preheated before changing, otherwise the oil in the cooling state will be very sticky, not clean, and the bottom of the tank precipitated iron filings and other dirt is not easy to be brought out.

Point four: Storage

In winter, if the excavatoris not used for a long time, it is necessary to do a good job of cold protection. If conditions permit, the engine cover can be covered with thermal insulation curtains or thermal insulation sleeves and other cold "clothing", if necessary, the equipment should be parked in the garage, and in front of the radiator with cardboard to block the cold wind, to protect the equipment.

To check the freezing point of the coolant used, empty the coolant in the engine when necessary to prevent freezing and freezing in the body, the body swelling and cracking, resulting in equipment damage.

If the battery is not used for a long time, it should be disassembled and stored indoors.
