发布时间：

Outriggers are the key components to ensure balance during operation. If the outriggers of the small crane have some faults, it will directly affect whether the normal and safe operation can be performed. The outriggers are essential components on the crane. It is inevitable that the middle outrigger will fail, so we must pay great attention to the maintenance of the [small crane outrigger].

Generally, the outriggers used by small cranes are hydraulic structures. After long-term use, the hydraulic system in the outriggers of small cranes will always have some problems of one kind or another, and these faults will affect the balance to some extent. Here we will give you the details. Introduce the fault phenomenon of small crane outrigger and its maintenance method.

1. The phenomenon that the left front and left rear vertical support legs of the small crane will automatically sink during lifting operations. At this time, we need to overhaul the hydraulic cylinder of the outrigger and replace the sealing ring in the outrigger.

2. The leakage caused by the internal damage of the hydraulic control check valve of the vertical outrigger of the small crane or the surface damage of the vertical outrigger cylinder, and the damage of the sealing ring causes the internal leakage.

Check the left rear vertical cylinder of the outrigger of the small crane, replace the inner sealing ring, remove the hydraulic control check valve, check whether the surface of the hydraulic control check valve seat is damaged or a small amount of sticky dust, and keep the sealing surface of the hydraulic control check valve seat. clean. Then check whether the automatic sinking of the left front vertical outrigger is eliminated.
