Five Key Points for Winter Maintenance of Used Excavators: Reduce Failures and Ensure Production

Shanghai Fanzeng Engineering Machinery Co., Ltd. – With the arrival of winter, the significant drop in ambient temperature presents unique challenges to the operation and maintenance of used excavators. Low-temperature environments are prone to triggering various equipment malfunctions, including hydraulic system jamming, engine startup failures, and accelerated wear of core components, all of which directly disrupt normal production schedules and increase subsequent maintenance costs. To assist global users in effectively addressing winter maintenance challenges, ensuring stable equipment operation, and minimizing production losses, Shanghai Fanzeng Machinery has compiled key winter maintenance points for used excavators, all of which are simple to implement and do not require professional technical qualifications.

Shanghai Fanzeng Machinery emphasizes that scientific winter maintenance is crucial to minimizing equipment failure rates and extending service life under low-temperature conditions. The practical and operable key points for winter maintenance are detailed as follows: One) Replace with minus fifteen degrees Celsius low-temperature special hydraulic oil. Low temperatures will increase the viscosity of conventional hydraulic oil, which may lead to hydraulic system jamming, oil leakage, and even irreversible damage to components. The application of minus fifteen degrees Celsius low-temperature special hydraulic oil can ensure the stable fluidity of the hydraulic system, thereby effectively preventing the occurrence of jamming and leakage faults.

Two) Preheat the engine for five to eight minutes prior to operation. Under low-temperature conditions, the lubrication performance of engine oil is significantly reduced. Sufficient preheating enables full circulation of engine oil, forming an effective lubricating film on the surface of core components, which can significantly reduce the wear of engines, transmission systems, and other key parts during startup. Three) Conduct regular charging and thermal insulation of the storage battery. Low temperatures will drastically reduce the storage capacity and discharge efficiency of the storage battery, often resulting in failure to start due to insufficient power supply. It is recommended that the storage battery be charged every fifteen days; when the equipment is not in use, the battery should be stored in a warm environment or equipped with a battery insulation cover to maintain its normal performance.

Four) Inspect the antifreeze concentration on a daily basis. Antifreeze plays a critical role in preventing water tank cracking under low-temperature conditions. Daily inspection of the antifreeze concentration is required to ensure that its freezing point is below minus twenty-five degrees Celsius, which can effectively avoid freezing and cracking of the water tank caused by extremely low temperatures. Five) Implement moisture-proof, dust-proof, and anti-rust protection measures for long-term inactivity. When a used excavator is out of service for an extended period in winter, it should be covered with a professional moisture-proof and dust-proof cover, and the surface of the equipment should be regularly wiped to remove dust and moisture, thereby reducing the risk of rust on the equipment body and core components.

Strict adherence to the above key points for winter maintenance can effectively reduce the failure rate of used excavators in winter by sixty percent and extend the service life of the equipment by more than thirty percent, while ensuring the stability of production progress and reducing unnecessary maintenance costs for users. To further address the concerns of global users regarding winter equipment maintenance, Shanghai Fanzeng Machinery has launched a comprehensive technical support and after-sales service system tailored for winter operation.

The company provides twenty-four hours a day, seven days a week multi-language remote technical guidance services. Regardless of the user’s country or region and the specific time, the professional technical team of the company can promptly respond to users’ questions about winter maintenance and needs for fault handling through remote methods such as telephone and video, providing accurate and operable solutions. For on-site maintenance needs that cannot be resolved through remote guidance, the company implements a global forty-eight hours response mechanism, dispatching professional maintenance technicians to the site for fault disposal.

In addition, the company has established regional spare parts warehouses around the world to ensure the rapid delivery of required spare parts for winter maintenance, minimizing the downtime of equipment. Headquartered in Xuzhou, the core hub of China’s construction machinery industry, Shanghai Fanzeng Engineering Machinery Co., Ltd. has been deeply engaged in the sales, export, and after-sales service of used construction machinery since its establishment in two thousand and ten.

Based on years of industry experience and professional technical strength, the company has built a comprehensive service system covering equipment supply, maintenance guidance, technical support, and spare parts supply, focusing on providing high-quality and cost-effective used construction machinery and worry-free after-sales services for global customers. The company’s product range includes core construction machinery such as used excavators, motor graders, and bulldozers, as well as a full range of used road machinery and general construction machinery, which can fully meet the diverse procurement and operational needs of different industries and projects.

Over the past thirteen years, the company has consistently adhered to the service philosophy of “customer-centric, quality-driven,” relying on strict equipment quality control standards, a professional technical team, and an efficient after-sales service system. It has successfully exported more than eight thousand units of equipment to over eighty countries and regions around the world, winning widespread recognition and trust from global customers. Each used excavator provided by the company comes from legitimate sources with clear usage records, and undergoes a rigorous one hundred and eighty plus point professional inspection and targeted renovation before delivery, ensuring stable performance in various environments, including winter low temperatures. In the future, the company will continue to optimize its technical support and after-sales service system, share more practical seasonal equipment maintenance skills, and provide global users with more comprehensive and reliable procurement and operation solutions for used construction machinery.
