How to use small excavators safely at high temperatures

In the hot summer, due to the influence of environmental temperature, it will bring many difficulties to the use of small excavators. For example, the "heart" part of the whole machine, the diesel engine, due to the increase in temperature, the oil viscosity decreases, and the lubrication effect decreases at the same time, which makes the power weak. , The internal parts are also prone to wear, which is a relatively common failure. Therefore, in summer, when doing a good job of maintenance of small excavators, it is necessary to carefully maintain the diesel engine, so that the small excavator can be used safely under the high temperature in summer and it is of great significance to extend the service life of the whole machine.

Why is the excavator handle laborious?

The total components of the excavator operating handle are two parts.The upper part is the operating lever,and the lower part is the operating pilot valve.If you open the outer shield of the handle,you can see that there are four plungers covered at the top,and the middle is a ten thousand.There are six hydraulic pipes connected to the bottom of the joint,which are 1 oil inlet pipe,1 oil return pipe and 4 pilot oil pipes.Generally,a small filter screen is installed at the joint of the oil inlet pipe.We need to clean it regularly to prevent oil from entering.The oil circuit is blocked.

What should be paid attention to when purchasing a second-hand excavator?

Excavators are not always used as an excavating machine,and builders sometimes use them to drive piles or use them to lay pipelines.Therefore,users need to pay attention to the condition of the bucket to ensure that there are no problems with the piling,crushing and walking devices.Another important part is the connecting pin and bushing of the bucket cylinder.The tightness of these places must be checked.Many problems are caused by negligence in maintenance and inspection.Another key point is to carefully check the connection between the rear arm and the excavator.If the connection under the rear arm is worn excessively,the value of the entire equipment may be lost.

How to deal with excavator accidents and its safe operation

When the hydraulic excavator is working normally,the hydraulic oil temperature should be between 50 degrees and 80 degrees.Before the machine is used,if it is lower than 20 degrees,it should be preheated;when it reaches or exceeds 80 degrees,it should be shut down to dissipate heat.
