Select a bucket with right capacity for your excavator

Large-sized hydraulic excavators are frequently used for the unloading work in the quarry project. Actually, this machine is of great significance for the whole pace of the project. Choosing the right bucket and teeth at the end of the stick will not only be helpful to reduce the operation costs, but also improve the productivity, probably more than you think.

Capacity is the main factors in bucket selection. To have a right capacity bucket, you need consider beforehand the machine lifting and breakout capabilities, material density and also the truck match. Machine capacity means how much lifting force the machine has for the bucket and payload at a given reach. Material density tells you the weight of a bucket load at ideal 100-percent fill conditions. The rock and stone fill is an exception, and usually, we estimate a 90 percent fill factors or less for shot rock.

At last, but not least, is the truck match, which actually is a prerequisite factor to think about in deciding the size of the bucket. Generally speaking, four or five passes is a perfect match for a large excavator in the 75-100 ton size. But if you need faster loading speed, you need think again the size and configuration of the bucket. It’s worth mentioning that a bigger bucket doesn’t always reduce loading time, since it may lead to less flexibility in digging and the resulting less production gain.

Excavator Maintenance in Plateau

The excavator working in Plateau may go wrong because of the extreme environment. Only knowing the reasons can we solve the problem to reduce the machine downtime and make the maximum productivity. With high altitude and low air pressure, the boiling point of the coolant decreases about 10℃ when the altitude increases 1000 meters, the boiling point decreases to 90℃ when the altitude is over 4000 meters. The decline of the coolant boiling point will cause the engine “boiling” and block the fuel pipe, making the engine be short of fuel supply and power declining. The oxygen is rare in the plateau, which is 90% of the plain. And the oxygen declines 10% as the altitude increases per 1000 meters. The declining oxygen results in heavy air mixture which can’t be sufficiently burned and makes engine produce dark smoke and reduce the power.

The roads in the plateau is rugged and steep, so the excavator needs to frequently change the driving power and speed to adapt to satisfy the complicated road conditions, which will lead to clutch separation and increase abrasion. The long and steep slopes increase the tractive resistance and make the clutch bearing overload, which may damage the clutch. And driving in the plateau needs super operating skills, otherwise, accidents may happen. Frequent braking will increase abrasion and cause damage to the machine.

In order to achieve excellent performance, the hydraulic excavator needs to be maintained regularly. The fuel oil should be used as specified. The parts should be checked to make sure the engine power is set as specified. Pay more attentions to brake and rotate system, which bears more loads to keep safe and reliable.

Excavator Sales Continues to Increase in 2017

Excavator sales volume continues to increase in January 2017, following the increasing trend of 2016. It is reported that China digger sales increases by 50% in January 2017, and Sany digger sales increases by 70%. In December 2016, China digger sales increase 75%, 15% exceeding the expectation. In the whole year of 2016, the industry sold 70320 units of digger, 11354 units more than 2015, which shows the symbol that the industry turns up from the downturn. Sany Heavy Industry, the leading construction machinery manufacturer, ranked No.1 in heavy excavator sales in 2016 and was the only enterprise that sold more than 10,000 units of excavators in China. 

In the year of 2016, Sany exports 2823 units of diggers, ranking No.1 in the industry. The reasons that Sany achieving such achievement lie in product structure adjustment and technology upgrade. The advanced technology plays an important role in Sany product manufacturing and development, which reaches world-class level. There are some reasons that make the whole digger industry rising.

With the demand for house building increasing, the need for construction excavator increases too. The new model replacing the old one is also one reason for the sales volume increasing. Generally, the service life for the construction machines is 8-10 years, so the machine bought in the year of 2008 and 2009 reached the time to be replaced. According to the market investigation, most of the used diggers have been running more than 10,000 hours, also should be updated. And some major infrastructure constructions like railway construction, city traffic construction, airport construction and new energy development increase the demand for the digging machines and promote the whole industry develop rapidly.

Excavator Examination before Working

Chinese Spring Festival comes to an end, people starts to return to work. Some people may have a body examination before working in order to keep a good physical and mental condition to make an excellent performance in a new year. That is the same rule for the excavator, which needs to be carefully checked after being idle for a long time in order to create the maximum productivity. Generally, there are three steps to go for a careful examination.

First, examination should be made before starting the machine. Check the fuel oil level and discharge the waste and water from the fuel tank. Check the engine oil level and quality. Check the hydraulic oil level and quality. Check the reduction gears and coolant to avoid any cracks and leakage. Check the lubrication conditions of the joint parts, add the lubricant if necessary. Keep the crawler belt and bolts in joint parts tight. Ensure the meters show accurate data. Second, examination during operation, preheat the hydraulic excavator with the temperature below 3℃ for several minutes. Set the machine in idle running for 5 to 10 minutes with no load to make the hydraulic oil temperature reach 40℃. In the cold days, rotate the upper body of the machine to 90°, then hold up the crawler belt to make it rotate for several circles to cast off the dirt.

Finally, check the ambient. Safety signs should be set in the entrance and surrounding of the machine parking place to avoid any dangers. The parking ground should be hard, flat and spacious enough for evacuation under emergency circumstance. The comprehensive examination can inject power to the excavator to make it create the maximum productivity and reduce the construction risk to the minimum at the same time.

How to Choose Used Excavator?

Plans should be made in advance when buying used excavator. The machine model should be chosen according to the project scale, there are small digger, medium excavator and large excavator in the digger market. We can tell the machine’s approximate service life from the machine’s appearance which can give you a first impression. Generally, the color will be relatively bright for an excavator working in the plain within 5 years

Careful check should be made during the choosing process since the second-hand excavator may have some problems. Different with the new machine, the used one works with lower speed when it bears full load. The engine stops before the joystick turning back to the original position. The electromagnetic system is in abnormal condition and the working device stops working. The used excavator may produce big noise or make poor performance in micro movement. The bucket moves slowly and the working device are stagnant. These problems should be recorded, which is very important for choosing the second-hand machine. What is more, check the hydraulic system to see whether it can work normally and examine the engine through its rotary sound and emission to tell whether it is capable enough to bear the required work load.

The second-hand machine may have a lower price but also may have some problems in performance. Therefore, more attentions should be paid when choosing the used machine to avoid paying more maintenance cost. Anyway, you can get the best used hydraulic excavator as long as you make comprehensive plan in advance and pay enough effort for it.

Compact excavator Maintenance Techniques

Compact excavator is widely used in engineer construction, where accidents may happen if notices are not paid enough. When the digger is working, none of the people should climb the machine or pass any items. Maintenance should not be done when the machine is working, which may cause unnecessary accidents. The hydraulic system, electric control system should not be adjusted casually and the operation should be done as specified. When discharging, the digger should start to work after the dump truck stopped stably. The digger should not collide with any parts of the dump truck when discharging and the bucket should not pass over the cab of the dump truck. The bucket should not be used to crush big and hard objects, which should be removed first.

The fuel oil should be chosen according to the ambient temperature, different bands and specifications should be matched with different working conditions, which is very important to keep the compact excavator in highly efficient. The fuel oil should not mix with any impurities, dust or water, all of which may cause serious abrasion to the fuel pump. The fuel tank should be fully filled to avoid any water producing in the interior of the tank.

Lubricant can reduce abrasion to the machine surface. It is very important to keep the lubricant clean and purified, otherwise, the lubrication will not work. Dust, sand, water and other impurities should not mix with lubricant. The filter can prevent the impurities entering fuel oil or other parts, thus it is very necessary to change the filter regularly and keep it clean. All of the above guidelines are very important and effective to keep the compact excavator in a good condition and make the maximum profits for the customers. If you want to maintain your machine well, just follow these guidelines.

How does Excavator Build the Mountain Road?

As the best digging tool of trenching and grading, excavator is widely used in road building. When building the mountain road, some guidelines should be kept in mind in order to guarantee smooth work and safety. The road should be wide and compacted as much as possible to avoid cave-in. Avoid working in rainy days, where the wet road and blurred sight will cause accident. Sharp turns should be avoided to guarantee the driver have a clear sight of the front road condition. The ramp angle should be considered according to the soil nature and avoid long and steep slope. Emergency lane should be set in the open space of the ramp. Avoid hard stones and creeks. Clear the barriers in the road and make sure that road surface can bear the traffic load.

Cautions and patience should be paid in the process of hydraulic excavator building road on the mountain. The digger should be parked stably, which is very important and also the precondition of the follow-up work. Using the bucket to remove the barriers like boughs and stones and then dig towards the specified direction. If the earth excavated from the mountain is not enough for the road building, branches and stones can be used in padding the road.

The excavator should walk with low speed in the road building process. Pay attention to the turning radius to avoid collisions. Of course the maintenance should not be neglected at any time, the malfunction should be solved in time before it affecting the working schedule.

Hydraulic Excavator Operating Techniques

Nowadays, more and more drivers have a good skill in operating hydraulic excavator. Safety comes first, only the excavator operator has a good knowledge of safe operating guidelines can he guarantee the safety of the machine and himself.

Check the ambient to make sure no barriers or rough terrains will impede the excavator to make a rotation. The crawler belts should be touched with the ground completely to improve the stability of the whole machine, which will prevent rollover and collision. The digging capacity can reach the maximum when the angle between the bucket cylinder and the rod, the arm cylinder and the bucket rod becomes 90°, the cutting resistance becomes the minimum when the angle between the bucket teeth and the ground is 30°. The digging efficiency can be improved when the boom and the bucket are used simultaneously. As we all know that hydraulic excavator can be used in various constructions, so different operating techniques should be used in different operating environments.

The excavator bucket should be prevented to dig rocks as much as possible since the hard rocks will make damage to the bucket. But when there is no choice, the operator should adjust the machine’s body and make the bucket cut the rock according to its cracks. Put the bucket teeth into the cracks of the rock and use the power of the rod. The complete rocks should be cracked before digging by bucket. Keep the machine stable and balanced when doing leveling work, it is very important to make a good coordination between the arm and the bucket for leveling. When the industry excavator is used to lift heavy-duty loads, the bucket should be put in an accurate position and no person should be close to the lifting loads, which will cause accident.

Small Excavator, the Warrior in the Mine Construction

With population increasing, the demand for energy grows rapidly. The mineral resource is one of the most practical energy resources in the earth. Small excavator is often used in the mineral construction with its high reliability and flexibility. There are vast territory and abundant resources in China. Huili county, located in Sichuan province of China, possesses abundant mineral resources, more than 60 kinds of mineral has been found till now. However, labor is the main force in the mineral construction since the infrastructure in the county is too weak. Underground mineral exploiting is always dangerous and many accidents happened in these years, therefore, how to improve safety and enhance working efficiency at the same time becomes the main issue for the mineral exploiting enterprises.

Considering the above issues, many mineral enterprises start to use small digger to instead of labor force since the small digger is more competent to do the mineral work. Being compact and flexible, the little machine can easily move around in the narrow space of the mine. The strengthened cab can protect the operator from the falling rubble, improving safety. The compact excavator can exploit about 15 tons mineral per hour, which equals to the workload of 5 people, improving working efficiency. What is more, the cost is much lower than employing labor force.

From the above, we can see that the small excavator is more suitable than labor force in the mine construction, which not only improves working efficiency but also guarantees safety and greatly reduces the probability of causing accidents. Therefore, the small digger is called the warrior in the mine, small body with strong power.

Excavator Cleaning Ways

Excavator is important construction equipment in many engineering constructions. It is critical to keep the excavator clean, otherwise, the slush may cause damage to the excavator. Then, how to clean the digger excavator in a better way becomes a critical issue.

First, we should prepare some necessary tools before cleaning. The tools include scraper knife, screw driver, watering can, diesel, detergent, duster cloth, rubber gloves, steel wire ball. When the tools are prepared, we can start cleaning the hydraulic excavator. What should be noticed is that the cleaning should be done in steps.

1.       Put the diesel into the watering can and pour to the stain. Scrape and wash the stain again after 10-30 minutes. The steel wire ball can be used to scrape the stain at the second time.

2.       When the diesel is used up, the detergent to clean heavy oil should be used, the detergent of heavy oil has strong power to remove the stain, so test should be made in case of leading the paint falling off. Also, this detergent has strong corrosion, which is bad for skin and nail, so rubber gloves and glasses should be wear.

3.       When the stain is cleaned, washing powder with clean water should be used to wash the excavator surface.

The above steps can be used repetitively until the excavator is completely clean.

Hydraulic Excavator for Construction Applications

The hydraulic excavators are designed for various operation uses, such as excavating, leveling, digging, loading and demolishing. Commonly used in construction, road building, mining, and civil engineering projects, the hydraulic excavators are applicable for various operations. Backhoe operation of hydraulic excavators is suitable for digging an area which is lower than the excavator. When the hydraulic excavator’s boom cylinder is at 90-degree angle while the arm cylinder stays vertically, maximum digging force can be obtained through the thrusting force of each hydraulic cylinder. Make use of this angle effectively to help you achieve the maximum working efficiency of the excavator. The digging range of the hydraulic excavator’s arm is from 30 to 45°. The angle may vary according to digging depth, but it is better to keep it within the above range if possible. Do not operate the hydraulic cylinders to their full.

You can use the hydraulic excavator to dig a trench efficiently by installing a bucket suitable for this job and adjust your excavator tracks to parallel the to-be-dug trench line. When digging a wider trench, excavate first both sides of the trench and then remove the middle part. In excavating operation, the excavator track should be adjusted vertical to road shoulder or cliff, with sprockets behind the excavator cab, so that the hydraulic excavator can retreat easily in case of an emergency. For excavator loading operation in a place where the swinging angle is small, working efficiency can be improved by parking the dump truck at where the excavator operator could see easily. It is more convenient for the compact excavator to load more material if the dump truck is loaded from rear rather than from its sides.

Excavator operator need know dangerous conditions in jobsites

Excavator operators usually work out in the field or construction sites; therefore, cautious investigation on the worksites is crucial to the safety of the excavator operator and to the safe operation. First of all, the operator should check the terrain and ground condition and use the safest operating method, try to avoid traveling or operating the excavator in areas with risk of landslide or falling stones, near cliffs, road shoulders or trenches, because the soft and loosen ground in these areas may not bear the excavator’s weight and vibration, as a result, the machine might sink or tumble down. The ground may become softer after heavy rain, explosion or earthquake. If the excavator has to work on a dam or near a ditch, vibration and machine weight may trigger a landslide, thus protective measures have to be taken prior to operation in order to prevent the excavator from tumbling down or falling over. For instance, to solidify the ground, keep a safe distance away from the ditch and assign a signal man when necessary.

If there are underground water mains, gas lines, cables or high voltage electric wires on the worksite, the large excavator operator must inform and ask related utilities providers to mark the area, and be careful not to cut any lines while digging the ground. When necessary, in order to prevent any unauthorized personnel from entering the construction site, it’s necessary to assign a signal man for the excavator operator and build a fence when operating on a highway. In addition, the operator must be extremely alert when operating on frozen ground as the excavator operation will cause the ambient temperature increase, which may result in soft and slippery ground. When traveling or operating the excavator in shallow water or soft ground, the operator has to check the type and condition of rock bed as well as the depth and water flow in advance.
