With the increase of infrastructure and municipal construction worldwide, winter construction has become an inevitable problem. How to ensure that excavators and other equipment can be better used in winter, the following are some precautions for the use of excavators in winter;

Precautions to avoid wear

After starting the equipment, run slowly for 3-5 minutes. After the end of use, it should also be operated at a slow speed for 3-5 minutes before turning off the flame, otherwise it will cause local high temperature and damage the parts. The lubricating oil has high viscosity and poor fluidity. In winter, the oil has poor flexibility and cannot spread across the friction surfaces in a short time. If the lubricating oil does not flow sufficiently, the machine runs at high speed, which will cause the shaft diameter of the turbocharger, crankshaft, and camshaft to wear. Intensified, it may even cause serious mechanical accidents such as cylinder pulling, tile burning, shaft holding, etc.

Equipment needs to "warmed up" in advance

The temperature in the cylinder is too low, the mixed gas cannot be formed in time, the piston and cylinder liner cannot reach the working condition, and the cylinder temperature is too low to reach the ignition point of the fuel; the viscosity of the lubricating oil increases the starting resistance, which will affect the start of the engine. Preheating can effectively improve the engine's low temperature starting performance.
