Selection and usage of backhoe
It is possible to use it also for agriculture though the backhoe (drag shovel) is special construction machineries. It has over tens of times power compared with human strength. The selection method and the usage when using it for agriculture were devised.
Method of selecting backhoe (drag shovel)
The too big one is not necessary if it uses it for agriculture excluding a special usage. I think that I often choose less than three tons in the body weight when thinking about the easiness of the relation and the movement of the license to do. Please note that the machine weight might exceed three tons even by less than three tons in the body weight.
In this case, because the machine weight might become even about two tons in the body weight it three tons near, it is not possible to transport it by two-ton car. It might often be seen to be portable as the backhoe of about three tons is piled up in two-ton car.
Size and driving qualification of backhoe
There is no car inspection about the one classified into the small sized special vehicle by the backhoe. The light vehicle tax hangs if it owns and it registers to the municipality.
It becomes a car of corresponding large-scale, specially or small and specially in the Road Traffic Law. It is large-scale, special or it is necessary to license small special if running in the public road. Then, the numberplate is also necessary. Registration to the municipality is needed. The compulsory automobile liability insurance is also necessary.
The one like the driving license in the site of the backhoe is "Vehicle system construction machinery driving skill training end certificate. " in Occupational Health and Safety Law. To use it for a personal usage on my site, I do not think the qualification for the necessity to exist though it is said that do not drive if this is not.
After the course is received, it is necessary to use it because there is not knowledge because it is a special machine and either it is dangerous when using it. It is necessary qualifications by all means if it undertakes a contract on business and for myself in the construction company.
The vehicle system construction machinery driving skill training has two kinds of qualifications from 3 tons in the body weight to less than 3 tons (small size) in the body weight. I received a special education of the compact car both faction construction machinery driving skill in around 1996 because owned backhoes were less than three tons in the body weight. This course ended in a day. It was necessary to prove though there was no field test of having done the spot skill training in the shop etc.
What is the body weight?
It is said the vehicle dry mass by mass that doesn't include the fuel, the hydraulic fluid, the lubricant, and cooling water, etc. detaching the working device (If it is a backhoe, boom, arm, and bucket, etc.) from a vehicle system construction machinery. It writes to the body.
What is the machine weight?
The working device (boom, arm, and bucket, etc.) necessary for work is installed in a vehicle system construction machinery and the fuel, the hydraulic fluid, the lubricant, and cooling water, etc. This is displayed in the body.
Example of ratings of backhoe (standard)
It is an example of Mitsubishi MM20CR standard issue that I am using.
|Weight of body||1,600kg|
|Total weight of machine||2,120kg|
|The maximum in bucket load||120kg|
|Rated power||17PS (12.4kW)|
|The highest running speed||4.1km/h|
|Mean contact pressure||0.3kgf/cm2 (29kPa)|
How to choose used backhoe
- Because the backhoe of the mini-is popular compared with the large-scale one, the price is expensive.
- Whether it is possible to load it into the car used to size that is appropriate for the work that I want to do or to move is an important factor. Loads that are a little larger than total weight of the machine are necessary.
- A method that the manner of operation is JIS method or special is confirmed.
- The squid of a rugged leakage of the oil leakage and other oil in the oil pressure part is often seen and chosen.
- Whether the oil pressure hose hurts is checked.
- Whether the oil pressure cylinder is transformed is seen.
- The one with a little decrease, damage, and transformation of Caterpillar is chosen.
- The bucket can be done and the one with few decreases is chosen.
- Abnormality often sees whether the condition and the sound of the engine.
- It is seen whether there is leakage of cooling water.
Usage to agriculture of backhoe
This photograph is used for burdock digging. In the burdock, the root is long and it is possible to dig up the soil easily by digging beforehand deeply near the burdock because of being deeply.
The backhoe can be used for not only the construction industry but also the labour for farming. It finds it useful very much in the part between Nakayama to whom the field is not so maintained. Generally, the above-mentioned work is done for adult ten.
I buy in the Middle Ages of 1996 when the house was built in the country and am using this. It has used it for the movement of the soil around the house, the stone wall volume, the well digging, and construction, the root cellar digging, and the culvert digging etc. of the warehouse of the iron frame. There seems to be a place variously still maintained because it originally built the house in the place with only the field. Not doing uses one's initiative and because it is possible to do by thinking to like it for myself better than asking the trader, it is possible to make it from the trader usual. Next, the usage of the backhoe was itemized.
- When the transportation car where the carrier moves by the oil pressure like the dump truck is used to move the soil with the backhoe, it is very convenient.
- It is convenient to move the big stone that cannot be moved by the hand when the stone wall is piled up.
- It digs and it is possible to dig up the well shallowly up to about 3-4m in depth. It digs in making known a little, the main body of the backhoe is put in the hole, and it digs when becoming deep by not reaching in the boom and the arm. (The vehicle exhaust emission is noted. )
- When the iron frame warehouse is constructed, the iron frame is lifted up, a heavy shutter is installed, and it is convenient.
- Work to dig up the root cellar that stores the sweet potato and the aroid, etc. is work in which backhoes are skillful most.
- It is possible to dig up the culvert and ditch easily.
- It is possible to use it conveniently also for widening the road that the car cannot go into it because the road where it goes to the field is narrow.
- It is convenient for burdock digging if it uses it for the labour for farming. Isn't it the best if digging up a long burdock so as not to break?I also have used it.
- It is necessary to dig up the soil deeply to bury compost under the soil deeply before asparagus is planted and it puts it. The backhoe is the best for such a usage.
- A big rock and the stone can be easily dug out in the bottom in the rice field.
Method of starting diesel engine
- The fuel, oil, cooling water, and meters are checked before the engine starts.
- To operate each operation lever, the safety lock lever is made the position of the lock.
- The accelerator lever is pulled from the lowest velocity a little.
- The engine key is adjusted to the position in which the plug is preheated, and it maintains it as it is.
- When the preheating lamp goes off, the engine key is turned to the position of the start.
- When the engine starts, the hand is separated from the engine key.
- When the engine starts, it is warm-up at the lowest velocity for 2-3 minutes.
- Meanwhile, grease improves to each part with a grease pump.
Storage of backhoe and maintenance in daily life
- After the backhoe is used, the bucket is lowered on ground. The blade is lowered.
- The safety lock lever is adjusted to the position of the lock.
- Grease is regularly injected with the grease pump because there are a lot of parts where grease is injected. Especially, the turn in the bucket often used improves grease every time.
- Dirt and the amount of lubrication oil and the operation oil are checked, and it replenishes it when it is few.
- The amount of the cooling water of the water-cooled engine (anti-freeze) is checked, and it replenishes it when it is few.
- The fuel in the diesel fuel tank is always made full. Otherwise, might do the be dewy of moisture in air in the fuel tank in the temperature change and water collect.
- The specific gravity and the amount of the liquid of the battery are sometimes checked. It sometimes compensates and [mitsuru] is done when not using it so much.
- Each part is sometimes checked in addition, and a wrong place is repaired.
