During and immediately after the operation, the temperature of the hydraulic oil is still high. Therefore, be careful when inspecting and maintaining the hydraulic system of the pile-driving arm excavator.
In the process of using the long reach boom excavator, if the hydraulic oil is overheated, its viscosity will be greatly reduced, and its lubricity will be deteriorated, which will increase the wear of the excavator equipment itself. The operating efficiency and performance of the equipment will have a negative impact.
There are two common forms of flameout of long reach front excavator. 1. The long reach front excavator will automatically turn off the flame during work and automatically turn off the flame. 2. The long reach front excavator stalled under heavy load and stalled.
No action is one of the more common failure phenomena during the operation of the long reach front excavator. It is manifested as: sudden no action of the excavator, no action after starting the operation, no action of the whole vehicle, no action of left and right rotation, no response of action, no action of handle , Hydraulic pressure does not work, etc.
The long reach front excavator slowing down seems to be a minor problem, but if it cannot be dealt with in time, it may cause major failures such as the excavator holding the car.
Ripper boom excavator oil temperature is high, also known as "high temperature of excavator, high temperature of hydraulic oil of excavator", it means that the hydraulic oil temperature of excavator exceeds 70℃ during operation, there will be high oil temperature or even alarm.
With the continuous development of technology, the excavator stump ripper arm has been continuously improved, so there is a new type of integrated rock arm. Compared with the traditional type, the integrated rock arm eliminates the bucket cylinder, and directly connects the forearm and the ripper into an integrated rock arm.
The material of the excavator stump ripper boom is generally Q345, also called 16 manganese. 16 Meng has a certain degree of metal extensibility.
The bucket cylinder of the old rock arm is more of a support. The integrated excavator ripper arms eliminates the bucket cylinder, and connects the tubing of the bucket cylinder to the stick cylinder, which greatly improves the strength and speed of the stick cylinder.
If you are an excavator driver, don't miss this article, how to use the heavy duty excavator bucket correctly? Huitong Machinery will tell you below.
The main structure of the excavator ripper boom is the huge forearm like the eagle beak, so it is also called the eagle beak arm. Compared with ordinary excavators, the boom has been thickened and heavier to cope with stronger impact.
