Important! 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 excavators 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.  excavator for sale.

Hydraulic Roller VS Mechanical Roller, which is the King of Road Machinery?

Road roller can be divided into hydraulic type and mechanical type. Discussions have been generated about the comparison of the two types in different aspects. The comparison mainly focuses on efficiency, safety, environmental protection, maintenance, price, reliability and comfort.

The mechanical roller has no front wheel drive and its working speed is fixed. The hydraulic one adopts full-wheel drive, which allocates more power to the vibrating drum, improving the compactness and reducing the compacting times, having more advantages in improving efficiency. And the hydraulic type needs no stop in the travelling process, improving 10% in efficiency than the traditional mechanical one. For safety, braking is an important factor that decides whether the machine can be stopped immediately once emergency happened. The brake of the hydraulic one combines with the joystick and can be locked when emergency happened. The brake and joystick of the mechanical one is separated, which may cost more time for the operator to stop the machine under urgent situation. Thus, the hydraulic roller has higher safety than the mechanical one, especially in mountainous area and dam construction. Also, the hydraulic type does a better job in heat dissipation than the mechanical one. The hydraulic type can be used in extreme temperature ranging from -40℃ to 60℃. And the hydraulic type is easier to be maintained.



Hydraulic roller always need work with motor grader, paving machine and other earth moving equipment. Although the hydraulic roller has higher price than the mechanical one, its advantages in high efficiency, high reliability, environmental protection, safety and ease of maintenance are obvious. All of the industry experts, representatives and media believe that the hydraulic type has huge market potential in the future.

The Secret to Reduce Excavator Fuel Consumption

As we all know that the fuel oil cost accounts for a large part of the excavator maintenance cost, it is very important to reduce your digger’s fuel consumption for lowering the maintenance budget. Actually, it is not so hard to reach that target, just pay more attentions to the details when operating your machine. 

Locate the machine in a higher position than the truck when it is loading to save engine power, which can improve 40% working efficiency. The cylinders can be put to the best use when the angle of the bucket cylinder and rod cylinder is 90°. The excavator rod can bear the maximum capacity when it is vertical to the ground. When trenching, the digger should dig the sides of the trench first then the center of the trench, which can save much power. The digger should work with low speed and reduce the rotation radius as much as possible.

What is more, the hydraulic excavator fuel oil should be maintained as well to reduce the fuel consumption. Always use recommended type of fuel oil which shall also be applicable even under extreme ambient temperatures. The fuel oil must be changed even if it is not dirty within the specified change interval. Malfunction of the machine are mostly caused by impurities, pay special attention to the prevention of any impurities when storing or filling the fuel oil. Fill the amount of fuel oil as specified, failure to do so could result in abnormality. Do not mix fuel oil of different grades or brands together.

Small Excavator Challenges the Impossible

On December 25th, when many people celebrated Christmas, Sany small excavator once again attended the famous China show “Challenge the Impossible” and performed another stunt that surprised everyone. Memory was revoked to November 13th, which is the first time that Sany excavator appeared in this TV show and performed tightrope walking in the height of 5.4 meters high from the ground. At that time, Mr Liu Renwei, Sany excavator engineer, perfectly showed his consummate operating skill and successfully completed the challenge. With the courage of the success in the first time, Mr Zhang Xiaocheng, the challenger of this time, created another miracle on the Christmas day.



Different with the challenge of the first time, Sany compact excavator turned into spider-man this time and climbed the tower with the height of 18 meters. The tower was divided into six parts and the light would be turned on when the excavator reached that part. The rule for the final success was that the when the excavator reached the top, its jib would be fixed with the groove in the bottom and the machine body hung in the air for 5 seconds. Full of difficulties and risks, this challenge became the focus of this show.



With strengthened parts and excellent bearing capacity, the 13.5-ton compact excavator perfectly cooperated with Mr Zhang Xiaocheng and successfully completed the challenge. Both the audiences in the site and watching TV applauded for this excellent performance. And for SANY, this was the best Christmas gift.

Guidelines for Truck Crane Lubricant

Truck crane is easily abraded during working, which will cause damages to the crane and even result in stopping working. Therefore, good lubrication is very important to keep the crane working smoothly. Generally, the parts and attachments should be checked every 2-3 months to make sure the lubricant is working, and the checking period depends on the machine’s working frequency and the ambient environment.



Different lubricants should be used for different parts, which will yield twice the result with half the effort. The parts that need to be lubricated include truck crane decelerator, wire rope, bolts, bearings, gears and impeller of hydraulic brake. There are some matters that need attention when lubricating. The lubricant in different models and brands should not be mixed, the lubricant should be kept clean, the pipeline should be washed frequently, the lubricant amount for the decelerator should not exceed the limit, otherwise, oil leak will happen.



There are some standards to examine good lubricant. The lubricant in high quality would not deteriorate in wet days and will form a layer of protective film to keep water and moisture away from the metal surface. Good lubricant would not be affected by temperature or cause chemical reaction with acid and soda. And lubricant in high quality has strong oxidation resistance to resist erosion of the salt. So much more attentions should be paid to choose the right lubricant for your truck crane, which will not only reduce downtime but also extend machine’s service life.

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 hydraulic 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.
