Why some excavators don't see roller: "Looking at the turret from afar is frightening to death, and looking at five pairs of load wheels near" is a kind of stem that military fans all know. For crawler construction machinery, there is no similar stem, because the "four wheel area" of construction machinery is quite different from military vehicles. For construction machinery, such as excavators, the roller is usually small, not only that, but also often wrapped. Although it can be counted several pairs in recent years, the number is the axle of the supporting load, and the roller is almost invisible. Of course, most excavators can see the roller directly, only one branch heavy wheel is wrapped. Several pairs of rollers can be counted, but the rollers cannot be seen.

Maintenance of important parts of excavator: Maintenance of important parts of excavator. 1、 Roller In the operation, it is necessary to prevent the supporting wheel from soaking in the coal slime water for a long time. After the completion of daily operation, one side of the track should be propped up to drive the walking motor to throw away the coal, soil, gravel and other debris on the track.

Did you know that the rollers can also be butter: Most of the heavy wheels of the excavators have been polished, and the wheel never needs to be replaced. Although it is almost impossible to repair after oil leakage, the roller can also be buttered! It can be used for 2000 hours after butter is finished and no oil leakage.

Common damage analysis and preventive measures of Crawler Bulldozer: 1、 Characteristics of crawler bulldozer walking device The driving system of crawler bulldozer includes frame (or frame), walking device and suspension. The frame is the framework of the whole vehicle, which is used to install all the assemblies and components to make the whole vehicle a whole. The walking device is used to support the body, which transforms the driving torque and rotary motion transmitted by the power device to the driving wheel into the driving force and speed required by vehicle operation and driving. Suspension is a connecting device between the frame and the walking device to transmit force to each other.

How to choose crawler of excavator: Crawler is an important part of excavator walking device, which is often divided into two categories: rubber track and steel track. Rubber track is often used in small and micro excavators, while steel track is used in medium and large excavators. These two kinds of tracks have their own advantages and can play a greater role in different working environment.

Be sure to pay attention to three reasons that will cause the excavator to deviate: Excavator's crawler track deviates, which means that the track has deviated from the track composed of guide wheels, rollers, drive wheels and carrier sprockets, commonly known as "dropping the chain", which is unwilling to be seen by the excavator driver and the owner Scene. On the one hand, to avoid track derailment, the driver needs to pay more attention when driving an excavator to turn. If he finds signs of initial track derailment, he should lift the track to idle. On the other hand, the frequent derailment of the track also indicates that the chassis itself has a problem and needs to be repaired.

What should I do if the excavator often "drops the chain"?: Excavator off-chain, commonly known as chain-off, refers to the track being separated from the track formed by the drive wheels, rollers, guide wheels, and carrier chain wheels. Because excavators often work in some harsh environments, and the crawler is a component that directly contacts the ground, when the operating ground is harsh and the operation is improper, it often leads to off-chain. Below we will list a few common reasons, and analyze how to avoid chains.

Why some excavators do not see rollers: "Looking at the turret to scare people away, looking at five pairs of heavy-duty wheels at close range" is a stalk that military fans know. For crawler-type construction machinery, there is no similar stalk, because the "four wheels and one belt" of construction machinery and military vehicles have Largely different. Construction machinery such as excavators and rollers are usually relatively small. Not only that, but they are often wrapped up. Although a few pairs can be counted up close, the roller shafts are counted and the rollers are almost invisible. Of course, most excavators can still directly see the rollers, only part of the rollers are wrapped.

The tightness of the track cannot be adjusted randomly! Keep this standard in mind!: The tightness of the excavator track is like the size of the shoes people wear. Only when it is adjusted to the right state can it go forward. Excavator often causes the change of track tightness in walking operation, and the tightness of track also determines the wear degree of chain to its contact parts.

The reason and repair of chain looseness of excavator: There are many reasons for the excavator to be out of chain. In addition to the impurities such as crawler soil or stones, there are also faults in the walking ring gear, carrier chain wheel, chain protector and other places that will cause the excavator to be out of chain. In addition, improper operation will also lead to the disconnection of the excavator.

One pipe burst after another? These points certainly did not do!: The high temperature in summer brings numerous troubles to excavators. The common problems such as the high temperature of hydraulic oil and the high water temperature of the engine have caught everyone by surprise, not to mention the thorny problems such as the oil pipe explosion from time to time.

How does excavator burn oil to deal with?: Digging friends are worried about the excavator and excavator parts fault, and burning oil is one of the more serious problems in the excavator engine fault, the phenomenon of burning oil is, the oil consumption of the excavator increases unusually, the engine in the operation with blue black smoke phenomenon, burning oil is the oil into combustion.
