Always be vigilant and pay attention to the safety of excavators

When we all enjoy the high profits and high returns brought by excavators,we often overlook an important issue that is-safety.Safety includes many aspects.Today we will first understand what needs to be paid attention to in the operating environment.

How to repair and maintain the four-wheel area of the excavator

I often hear from friends about the problems such as oil leakage of excavator support wheels, broken sprocket wheels, and inconsistent tightness of the walking tracks, and these are all problems related to the four wheels of the excavator. The four-wheel area is directly related to the working performance and walking performance of the excavator. If the excavator is to travel and fast, maintenance is the key. The following are the maintenance methods related to the four-wheel area:

Talking about the inspection method of excavator winding machine in detail

It is understood that 43%of excavator failures are caused by improper daily maintenance,which shows how important daily inspection and maintenance are to excavators.

The hydraulic oil replacement method that makes the excavator reborn

The traditional method of replacing the hydraulic oil of an excavator is nothing more than drawing out the hydraulic oil in the hydraulic oil tank, replacing the hydraulic oil filter element, and refilling the new hydraulic oil. This method can only replace 48% of the hydraulic oil in the system. When 52% of the dirty oil remaining in the system is mixed with the new hydraulic oil, the service life of the hydraulic pump and other components is greatly reduced.

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.
