The overall maintenance principles for the lifting platform should be followed according to the platform's manual. Different models of lifting platforms with varying scope and production processes will have different manuals and maintenance instructions. In addition, we must pay attention to the specific maintenance measures and precautions required for the lifting platform due to weather changes.
Winter and summer maintenance principles and methods differ, primarily due to the material of the hydraulic lift platform and the choice of hydraulic oil.
When selecting materials, it's crucial to consider the following: For hydraulic lifting platforms designed for cold weather conditions, it's important to increase the steel's hardness appropriately and avoid excessive changes in expansion coefficients. This is a primary concern before choosing the materials for manufacturing the lifting platform. In northern regions, where hydraulic lifting platforms are used, temperatures can drop to around -30 degrees Celsius during the cold season and rise to around 30 degrees Celsius in the summer, resulting in a temperature difference of 60 degrees. Such drastic temperature fluctuations can pose serious safety issues if the wrong materials are chosen for the platform.
Next, we must timely replace hydraulic oil based on seasonal changes. Different seasons require different hydraulic oils, which is a fundamental principle for any equipment. We must not unnecessarily add to the obstacles of usage and maintenance. Summer hydraulic oil does not contain antifreeze, while winter hydraulic oil must include it. This is basic knowledge in hydraulic oil usage. Depending on the location, there may be more stringent requirements for the hydraulic oil, as well as specific material requirements.
We must regularly clean the hydraulic cylinders, particularly checking for oil leaks and ensuring all connecting parts are functioning properly. These aspects should not be overlooked during use, and they are common issues and considerations we frequently pay attention to when operating hydraulic lifting platforms.
