Buying a escavadeira usada is a very important decision, and the biggest risk is buying an accident vehicle. The fuselage structure of a vehicle that has been in a major accident will be severely deformed, and even after repair, there may still be many hidden injuries, and the probability of failure during future work is very high. Therefore, the editor would like to remind you that when purchasing a used excavator, buyers need to pay attention to the following aspects.
Check the cab
For stone smashing and rollover accidents, the cab is the first to be affected. If the paint on the top and side of the cab is severely peeled off or repainted, it is suspected of being an accident vehicle. The original cab stamping parts have more arcs and a more complex structure. The later sheet metal repair is more difficult. The repaired cab can be seen by looking at the top a few more times.
If the cab is severely damaged, the four-sided glass and the driving interior must also be damaged and replaced. When the four-sided glass of the cab is inconsistent with the production date of the whole vehicle or the difference between the new and old interiors is particularly obvious, you need to pay attention to judgment.
Check the big and small arms and the frame
When the excavator rolls over or rolls over, the external frame and big and small arms and other parts are easily seriously damaged and deformed under the action of external forces. After adjusting the excavator, you can stand at the main control valve to see whether the big and small arms have tilt angles.
In severe rollovers, the frame and hydraulic system engine and other parts are deformed, dislocated, and damaged. At this time, it is necessary to focus on checking whether the exterior parts such as the X-frame, big and small arms, cab, side doors, etc. have traces of paint spraying and whether the gaps between the connections of various parts are too large or uneven.
Check the anti-collision beam and side beam
The anti-collision beam and side beam are the outermost protective devices of the excavator. When an accident occurs, the anti-collision beam and side beam are the most vulnerable parts. If the anti-collision beam and side beam are "injured", the car must be an accident car.
How to check whether the anti-collision beam and side beam have been damaged? Simply put: one is to look from a distance and the other is to look closely.
Observe from a distance: When inspecting a second-hand excavator, first observe whether the anti-collision beam and side beam are smooth from 10 meters away, and observe whether the reflectivity of the paint surface has changed. If the side beam has been repaired after a collision, the smoothness and reflectivity can reveal traces.
Look closely: For popular excavators, there are brand new side beams and anti-collision beam aftermarket parts for sale on the market, which requires close observation. First, look at the gaps between the side beams and the upper body cover. The gaps of vehicles that have not experienced accidents must be uniform, and there will be no obvious changes in width. Secondly, check whether there are welds on the inside of the side beams. The repaired side beams are generally only surface treated on the outside. The cost and difficulty of the inside treatment are too high, and general maintenance personnel will not do this. This is also a path left for us to check.
Check the X frame
If an excavator has a serious rollover accident, then the X frame of this vehicle is likely to have been deformed. The cost of repairing and replacing the X frame is very high, and the traces after timely repair are also more obvious.
If the deformation of the X-frame does not affect its use, the refurbisher will generally use "mud paste" or spray paint to cover it. This requires cleaning the mud before inspection.
If the deformation is serious but the equipment has a certain repair value, the refurbisher will generally correct it. The appearance of the X-frame after correction will be more obvious, and wavy correction marks are likely to appear on the edges of some deformed parts of the X-frame.
Check the hatch
The hatch of the excavator is a vulnerable part. It will be bumped and bumped accidentally during daily construction. It is normal to repair or replace the sheet metal for beauty. Therefore, this cannot be used as a direct basis for judging whether an excavator is an accident vehicle, but it can be used as indirect "evidence".
When you suspect that this is an accident vehicle through other means, you can use the location of the hatch to assist in the judgment. For example, if you find that the glass on one side of the cab has been replaced and the side beam has signs of repair, and at the same time verify that the hatch on the same side has been repaired, it can be basically determined that an accident has occurred.
