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 Memory was revoked to November 13th, which is the first time that Sany excavator appeared in this TV show and performed tightrope walking in the height of 5.4 meters high from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.
