Transfer of second hand mining excavator

1. Zx240-3 is suitable for demolition, reconstruction, water conservancy, river cleaning, quarries, cement plants. If you go to a mine, you can install a crushing hammer to crush materials. Except for mining and large-scale projects, you can do it, but be careful. You are an EFI truck. You must pay attention to the fuel. It's easy to cause nozzle blockage. It's 30000 yuan to replace a set of nozzle and high-pressure pump, If you don't know anything about the excavator instry, I advise you to transfer it. Hitachi's EFI car is not suitable for the actual situation of the Chinese market. It's extremely expensive for you to use the original procts for maintenance, Hitachi has now switched back to direct injection proction, and Hitachi EFI vehicles are failed procts in China. You see.

Excavators are different from family cars, and do not need to transfer ownership. Excavators have a certificate. As long as the seller provides the certificate and original invoice, the transaction of excavator purchase can be completed

excavator, also known as excavating machine, also known as excavator, is an earth moving machine that excavates materials higher or lower than the bearing surface with bucket, and loads them into transport vehicles or unloads them to the stockyard

the materials excavated by excavators are mainly soil, coal, silt and soil and rock after pre loosening. From the development of construction machinery in recent years, the development of excavator is relatively fast, excavator has become one of the most important construction machinery in engineering construction. The three most important parameters of excavator are operating weight (mass), engine power and bucket capacity

According to the scale, excavators can be divided into large excavators, medium excavators and small excavators

According to different transmission modes, excavators can be divided into hydraulic excavators and mechanical excavators. Mechanical excavators are mainly used in some large mines

According to the usage, excavators can be divided into general excavators, mining excavators, marine excavators, special excavators, etc.

5. According to the bucket, excavators can be divided into front shovel excavators, backhoe excavators, dragline excavators and grab excavators. The front shovel excavator is mostly used to excavate the materials above the surface, and the backhoe excavator is mostly used to excavate the materials below the surface.

(1) backhoe excavator backhoe type is the most common one we have seen, backward downward, forced cutting. It can be used for the excavation below the stop working face. The basic operation modes are: Ditch end excavation, ditch side excavation, straight line excavation, curve excavation, keeping a certain angle excavation, ultra deep ditch excavation and ditch slope excavation

(2) shovel action form of shovel. It is characterized by "advance upward, forced soil cutting". The front shovel has large excavation force and can excavate the soil above the parking surface. It is suitable to excavate the dry foundation pit with a height of more than 2m, but the up and down ramps must be set

(3) dragline excavator

dragline excavator is also called cable shovel excavator. Its excavation features are: "backward downward, self weight cutting". It is suitable for excavation of class I and II soil below the parking surface. When working, use inertia force to throw the bucket out, dig far, dig radius and dig depth is larger, but not as flexible and accurate as backhoe. It is especially suitable for excavation of large and deep foundation pit or underwater excavation

(4) grab excavator

grab excavator is also called grab excavator. Its digging characteristics are "straight up and down, self weight cutting". It is suitable for excavating class I and II soil below the parking surface, and is often used for excavating foundation pit and caisson in soft soil area. It is especially suitable for digging deep and narrow foundation pits, dredging old channels, digging silt in water, or loading loose materials such as gravel and slag. There are two excavation methods: ditch side excavation and positioning excavation

common faults

1; Jump & quot; (1) the transmission mechanism of w4-60 excavator is a mechanical shift transmission mechanism, which relies on the sliding gear sleeve to move axially on the fixed gear sleeve and mesh with the driven gear of each gear. In the process of frequent shifting, the tooth end face of the above meshing gears is easy to be ground into a cone, resulting in the rection of meshing performance and leading to & quot; Jump & quot

(2) the performance of the self-locking mechanism is to prevent the transmission from deteriorating; Jump gear;, This type of excavator is equipped with self-locking steel balls and springs in the box cover holes above the shift fork shafts of gears II, III, IV and V and in the shift fork shafts of gears I and V

when the spring which plays the role of positioning and self-locking weakens or breaks, the self-locking performance of the self-locking mechanism will decline until it disappears, resulting in transmission failure; Jump & quot;. At the same time, if the groove on the positioning steel ball or shift fork shaft is worn, it can also cause transmission & quot; Jump & quot

(3) the gearshift device is not adjusted properly. The transmission of this excavator adopts mechanical manual gearshift. If the gearshift lever, longitudinal axis, transverse axis and vertical fixing screws are loose, the transmission will be damaged; Jump & quot

(4) the sudden change of the external load will also lead to the change of the transmission e to the working nature of the excavator and the design of the excavator itself; Jump & quot;. When the road surface is uneven, the machine is driving downhill or the driving route is improper and the external load suddenly changes,

this sudden change of load will act on the gear meshing gear of the transmission through the wheel and transmission shaft, causing the gear meshing gear to be disengaged e to the axial thrust, causing the transmission & quot; Jump & quot

(5) improper operation of the excavator on the slope (especially downhill driving), if the operation is improper, it will also lead to transmission & quot; Jump & quot

(1) operate in strict accordance with the operating proceres and driving essentials, and try to avoid shifting; Tapping & quot;, In order to rece the wear of gear pair

(2) strictly implement the maintenance system and strengthen the maintenance of the shift device. When the linkage of the gear shifting device is not connected, it should be adjusted in time to ensure the good performance of the gear shifting device

(3) pay attention to the repair and maintenance of the self-locking mechanism, and timely repair or replace the positioning steel ball, spring and fork shaft whose positioning function is reced or lost, so that the self-locking performance of the self-locking mechanism is in a good state

(4) when assembling the transmission, the operation should be carried out in strict accordance with the operating proceres to ensure that all parts of the transmission are adjusted correctly and tightened properly. In case of large downhill road, the driver shall operate in strict accordance with the action essentials of downhill, and must not violate the rules

3. If you send this online, you are not afraid of being cheated.
if you want to transfer it, you can go to the second-hand excavator market on the spot to investigate, and they can also sell it. For example, Shanghai jueyue, Kunshan Xinwo, Guangdong second-hand excavator market and other regular venues, you can inquire about the price, and you can have a bottom first, and then negotiate

4. This will not, the agreement has been written, the sale has been completed, the excavator is yours, hope to adopt.

5. Hey, hey, you can't ask for samples from the Internet when you transfer your ownership locally

6. 1. Purchase of second-hand excavator does not need to transfer ownership
2. The seller only needs to provide the certificate of excavator, purchase the original invoice and sign a transfer agreement. Like a normal second-hand transaction, but in the process of transaction, we must sign a purchase contract ·!!! Get the certificate, purchase invoice and other materials<

the ownership transfer of excavator is different from that of automobile business, generally, it is not necessary to transfer the ownership.
only the seller needs to provide the certificate of excavator, purchase the original invoice and sign a transfer agreement,

the ownership transfer is also OK, go to the vehicle management office where the excavator license is located, and the proceres are very simple

7. Just sell the machine to the company, the sales contract (sign the purchase contract with your company), or transfer the gift, and write down the rights and responsibilities clearly. If not, it should not be too expensive to ask the law firm to write.

8. It's better to write a transfer agreement for personal purchase and sale of excavator. Huwang second hand excavator market reminds you
