How to maintain the truck crane in winter

Recently, a large area of the country suffered from rain and snow attacks, cold climate easily lead to crane start difficult, so we need to strengthen the crane maintenance, to ensure the safety and normal use of equipment.

1. pay attention to maintain the cooling system of crane internal combustion engine

(1) add antifreeze. When the temperature is too low, but also meet the conditions, antifreeze can be used. Before the use of the cooling system should be thoroughly cleaned, and the selection of good quality and low corrosion antifreeze, can avoid the antifreeze liquid quality and corrosion of parts.

(2) insulation work of internal combustion engine should be done well. Generally speaking we can in front of the water tank with internal combustion engine cover cloth, water tank, reduce heat loss, keep the engine temperature, prevent the temperature too low.

(3) remove the scale in the water jacket and check the water drain switch. To clean the water jacket of internal combustion engine, remove the internal scale, prevent the accumulation of excessive scale, affect the cooling of the internal combustion engine, make the engine temperature too high, and also maintain the water drain switch.

(4) check the working condition of water cooled internal combustion engine thermostat. In order to ensure the rapid warming of the internal combustion engine in winter, the method of removing the thermostat is adopted, but it must be installed again before summer comes.

2. pay attention to replacing all kinds of oil in the crane

(1) replace hydraulic or hydraulic transmission oil. Before the cold wave comes, the hydraulic and hydraulic transmission oil should be replaced by hydraulic and hydraulic transmission in the hydraulic system and hydraulic transmission system of the working equipment of the equipment, so that the hydraulic system and the transmission system of the working device will not work well in winter due to the large viscosity of the oil.

(2) replace fuel oil. The fuel low freezing point, good low temperature flow, selection of the general principle is: the fuel to 6 degrees lower than the freezing point temperature.

(3) change gear oil and grease.

(4) change the oil. Low viscosity diesel engine oil

3. pay attention to the maintenance of the electrical equipment of cranes

(1) maintenance starter. Keep all parts of starter clean and dry, especially the brush and commutator should be in good contact.

(2) check and adjust the electrolyte density, pay attention to the insulation of the battery. May be appropriate to increase the density of the electrolyte, the electrolyte density is too low to avoid, and the battery casing cracking accident. In general, the electrolyte density of the battery can be raised to 1.28 in winter.
