KB spider cranes are widely used in lifting work in narrow spaces such as factory workshops, commercial buildings, rooftops, railways, power stations, etc. Due to its wide range of uses, high quality and low price, spider cranes are used all over the country.
The maintenance and care of crawler spider cranes can promote the good performance of the equipment and extend the service life of the equipment, thereby reducing unexpected accidents during operation and increasing work efficiency. With the arrival of winter, the temperature drops and the air becomes cold, and the small cranes should also be kept warm to ensure the normal and stable operation of the cranes in winter. KB crane summarizes the following points for winter crane use precautions.
1. Engine:
To prevent the crane from freezing during use, delaying time, causing risks and economic losses, the following diesel grades should be selected according to the temperature in winter:
When the temperature is ≥8℃, it is best to use 5# diesel;
When the temperature is between 4℃ and 8℃, it is best to use 0# diesel;
When the temperature is between -5℃ and 4℃, it is best to use -10# diesel;
When the temperature is between -14℃ and -5℃, it is best to use -20# diesel;
When the temperature is between -29℃ and -14℃, it is best to use -35# diesel;
When the temperature is between -44℃ and -29℃, it is best to use -50# diesel.
2. Hydraulic oil:
Hydraulic oil is a hydraulic medium used in hydraulic systems that utilize liquid pressure energy. It plays a role in energy transfer, anti-wear, system lubrication, anti-corrosion, anti-rust, cooling, etc. in hydraulic systems.
The low temperature in winter affects the viscosity of the hydraulic oil. You can replace the antifreeze hydraulic oil before the weather cools down. The temperature of the hydraulic system hydraulic oil during operation mainly puts forward requirements for the viscosity-temperature and thermal stability of the hydraulic oil. It is recommended to use low-temperature resistant hydraulic oil with a label of HS-46 for small cranes in winter.
3. Engine oil:
The temperature is low in winter, and the engine oil will become thicker at low temperatures, which will not only affect the vehicle start-up, but also increase the wear of the parts, and the damage to the engine is obvious. In winter, it is recommended to choose 5W-30 engine oil for crane engine oil.
4. Install a cold start auxiliary device:
The device adds a cylinder heater to the crane engine. Its working method is to first release the original coolant, then add a special coolant for winter, and then heat it. After heating, there is no need to remove the cylinder heater.
5. Coolant selection:
The temperature is low in winter, and the solidification of coolant will cause the engine cylinder to bulge and crack, thus causing damage to the crane. To prevent the coolant from solidifying due to the temperature, you can choose the coolant labeled HEC'-Ⅱ-45 and use it when the temperature is ≥-20℃.
The above are the precautions for the use of spider cranes in winter. Winter vehicle maintenance cannot be ignored, and small cranes must be maintained.
