Let small excavator hydraulic breaker not fear the cold winter

1. Comprehensive physical examination before winter

For the hydraulic breaker equipped with small excavators, a comprehensive physical examination before winter is the first key step to ensure its smooth "wintering". Before preparing to store the breaker, it is necessary to carry out a detailed safety inspection of its various parts. Carefully check whether there are hidden dangers of failure, such as the degree of wear of key parts, whether the connection parts are stable, and whether there are signs of looseness. At the same time, all parts of the breaker must be cleaned thoroughly, just like a deep cleaning SPA for the right-hand man of the small excavator, so that it can welcome the arrival of winter in a refreshing state.

2. Replace the oil seal in advance

The oil seal plays a vital role in the protection of the hydraulic system. It is like a solid line of defense to prevent impurities from invading and polluting the hydraulic system of the small excavator. The time nodes for replacing the oil seal are different for breaker hammers of different specifications. The oil seal of a small breaker needs to be replaced in time when the working time reaches about 500 hours; while the large breaker needs to be replaced after about 300-400 hours of working. When replacing the oil seal, you must pay special attention to the cleanliness of the oil seal. Any impurities may enter and cause serious pollution to the hydraulic system. Once the oil seal is broken, the most intuitive manifestation is that the breaker of the small excavator will leak oil, and the internal leakage will cause insufficient operating pressure of the breaker, affecting the overall working efficiency of the small excavator. Therefore, in this special period of winter, special attention should be paid to the replacement of hydraulic oil seals to ensure the efficient operation of the small excavator.

3. Placement environment requirements

As a precise "partner" of the small excavator, the hydraulic breaker has very strict requirements on the dryness of the storage environment. It must not be placed in a humid, saline or dusty harsh environment for a long time. In order to avoid the ground water entering the breaker and causing rust, corrosion and other problems, it is recommended to use a special bracket to raise the breaker for storage, just like creating a dedicated "safe nest" for it. In addition, before placing it, it is necessary to exhaust all the nitrogen in the breaker, and use the drill rod to carefully push the piston into the middle cylinder body to take all-round protective measures for this important component of the small excavator.

4. Daily maintenance
The working environment of the breaker hammer of a small excavator is often very harsh, so daily maintenance is essential. Every time you remove the drill rod, you should frequently check the wear of the vulnerable parts in the lower cylinder, and also carefully check the piston, the drill rod striking surface, the drill rod, and the inner and outer sleeves and other key parts. Only by doing a good job of daily maintenance can the breaker hammer always maintain a good condition during the work of the small excavator and successfully survive the cold winter.
