Huashan media: Volvo, Hitachi, Doosan excavator competition

As an experienced excavator, many kinds of excavators may be opened. The following is a machine hand determined by driving different brands make use of experience summed up the machine, everyone to see if he is right?

Volvo EC55B

Volvo EC55B, the engine throttle to more than half the fuel consumption at about 20, big, if I'm not mistaken is 80 wide bucket, fast speed, good strength, for the mountain to dig a tree of operation is very good, with the oil pump, the oil leak with screen. The operating lever is very light, and the driving feeling is good.

The cab is simple, shortcomings, does not reflect Volvo's luxury, engine in 2000 hours the foot screw loose, often need tight, high quality requirements of oil, such as oil and petrochemical, at 1500 hours, there will be insufficient fuel hold car flameout phenomenon (perhaps is the reason oil dirty). The battery may need to be replaced in about 1500 hours. The air conditioner is not cool.

Hitachi 60

Hitachi dug a small work very fast, every day will work a little more than any other brand machines, this is not the case in stone. Oil saving, the engine 1500 turns e mode under the case of oil consumption of about twenty per hour.

In addition, it has to be said that the driving comfort is very good, the cab is big enough, the seat can be put down, and you can take a nap. The love is the same level of air conditioning, dug a small little air conditioning is very cold, the weather can be 35 degrees above the cab glass blowing water after the hot weather temperature down as long as the second line, the front air inlet 360 rotating, bright spot is placed below the mineral water with air blowing up. Have a cold storage effect, behind a cold storage box, can store water and food. The quality of the machine is not said, at least 10 thousand hours within the basic need not to repair, only need to change the vulnerable parts, daily maintenance.

Let me tell you personally feel that this type of defect, the first is no place to put the yellow oil, some people may say that can be placed on the rotary motor, motor rotation but then there will be a risk of explosion pressure tubing, the second disadvantage is too big ass (for Dasan operations, will have third disadvantages, ass) there is big arm detours come loose, this is a flawed, rarely see 7000 hours without welding small Hitachi. Finally, if there is a pump oil machine, this machine is perfect, the above shortcomings do not affect the use of it, it will only be covered by its other advantages.

Dou Shan 60-7

Next is Doosan 60-7, Yanmar engine, fuel consumption is around 30, operation lever is light, elastic seat is not bad, equipped with electronic pump oil, oil well pump, power is good, speed is slow.

Disadvantages of dozer lift is not high, low chassis, met Lan Tian was unlucky, the new air conditioner will suck, give people the feeling of electric fan, cab equipped, sound insulation effect is not good, a man have tinnitus, thin door, when the branches touch on digging Chashan deformation by broken glass. The diesel oil filter is too brittle, and it is broken a little when it is maintained. There is a high temperature in about 1500 hours, and it is better to remove the thermostat.

The split arm appeared in 3000 hours. The middle arm and butter nozzle opened the steel thin arm of the arm, and it was also about 3000 swing.

summary

Doosan 60-7 is not suitable for wetland, this is not the Hitachi 60 chassis, because without it, dozer nor it is high, it is prone to be chassis frame, we need to pay attention to this, three sets of small dig contrast, Doosan machine strength is also good, Hitachi power point, Volvo. Good. In terms of speed, Volvo and Hitachi over Doosan, the operation view and say, side arm machine vision, which can best reflect the change in agricultural farming road ditch digging machine, the day will lead more comfortable than cervical arm.

Maintenance, accessories Volvo is certainly more expensive, Hitachi, Dou mountain to buy accessories, Doosan cheaper, if it is the Hitachi explosion tubing is good for oil distributor Doosan in the cab for the soles of the feet, tubing is very inconvenient, often need to wear this dress that sometimes, wrenches have not changed.

In a word, these machines have both advantages and disadvantages, and of course they all have their own advantages.

I hope this article is helpful to everyone's work.
