The crane maintenance knowledge in winter

1. Pay attention to maintenance of internal combustion engine cooling system

• Filling antifreeze. When the temperature is too low, can use antifreeze. Thoroughly clean the cooling system before use, And should select good quality, low corrosion of antifreeze, to avoid the antifreeze fluid quality and corrosion.
• Make internal combustion engine heat preservation work. Generally speaking in front of the water tank with internal combustion engine block cloth, water tank, reduce heat loss, to avoid engine temperature, temperature is too low.
• Root out the incrustation in the water jacket and inspect the maintenance drain switch. Clean the water jacket of internal combustion engine, clean out inner scale and avoid excessive accumulation of scale, Affect the cooling of the internal combustion engine, so that the machine temperature is too high, together with maintenance water switch.
• Look into the status of thermostat for water-cooled internal combustion engines. In order to ensure the rapid warming of the internal combustion engine in winter, you can take away the thermostat, but before the summer comes, you must install it from the top.

2. Pay attention to replacing all kinds of fluids

• Replace hydraulic or hydraulic transmission oil. Before the cold spell comes, Hydraulic and hydraulic transmission oils shall be replaced with hydraulic and hydraulic transmission systems for equipment operating equipment. To avoid winter oil viscosity increased, resulting in operating equipment, hydraulic systems and transmission system operation is not good.
• Replacement fuel. With low pour point, low temperature oil with good fluidity, usually the selection principle is: 6 DEG C to fuel pour point lower than the ambient temperature.
• Replace gear oil and grease.
• Replace engine oil. Use low viscosity internal combustion engine oil

3. Pay attention to maintenance of electrical equipment

• Maintain the starter. Keep all the parts of the starter clean and dry, In particular, the brush and commutator should be touched.
• Check the electrolyte density and pay attention to the heat preservation of the battery. May be appropriate to increase the density of electrolyte, Avoid electrolyte density too low, Attack shell crack battery trouble. Generally speaking, in winter, the electrolyte density of the battery can be raised to 1.28.
