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 Memory was revoked to November 13th, which is the first time that Sany excavator appeared in this TV show and performed tightrope walking in the height of 5.4 meters high from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

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.

Excavator and the Miss World

Excavator stands for strong power while the Miss World represents beauty and elegance, people have never imagined that the two totally different things could have connections with each other.

On September 28^th, the Miss World came to Sany and had a close interaction with Sany excavator.

The 20 beauties wearing Sany uniform made a fashion show in the stage, perfectly combining their elegance with Sany uniform.

The combination of Sany excavator and the Miss World has great significance for Sany going global. Started in the year of 1951, the world beauty contest has covered more than 150 countries and become the most influential contest in the world which has the longest history and the most supporters. As a leading construction equipment manufacturer, Sany has established four R&D manufacturing bases in India, America, Germany and Brazil and put 5%-7% of annual sales into innovation research in order to keep dynamic in the world market. In the year of 2012, Sany acquired Putzmeister as the international headquarter of concrete machinery. As the co-sponsor of the Miss World in Laoning district of China, Sany shows strong determination to go global and bear corresponded responsibility. The same mission to these beautiful and young girls, as the Miss World, good looking is just one aspect, what is more important is that they should bear the responsibility to advocate beauty, health and peace to the world.

It is a beautiful picture that the Miss World poses in front of the excavator. The beauty contest doesn’t come to an end, the beautiful girls have to work harder to be standout in the finals, so does Sany. Only by continuous innovation and harder work can they walk further on the way to the world.

What are Excavator Precautions?

Tipping-over may occur if the excavator is on uneven ground or on a slope. To avoid such accidents, the following instructions should be taken when the excavator is operated on uneven ground or on a slope. Firstly, keep the excavator engine running at a low speed. Secondly, choose the low-speed travel mode. Thirdly, operate slowly and observe the motion of the excavator. Finally, never attempt to travel on a slope with the bucket loaded or with a load lifted.

In detail, we should never attempt to travel up/down a slope with a grade greater than 30° and never attempt to cross a slope with a grade greater than 15°. The seat belt needs to keep fastened. The bucket should be pointed towards the traveling direction and 20~30cm off the ground, and be released immediately once the excavators slips or lose balance. The direction change is forbidden on a slope, or the machine may slip and tip over. We should avoid crossing a slope as possible as condition allows, because slipping or overturn may result.

We should also remember that the upper structure of the excavator could never be swung on a slope or to the downhill direction; otherwise, the excavator may tip over. If such operation is necessary, swing the upper structure and the boom with great care. In the event that the engine stalls on a slope, lower the bucket to the ground immediately and neutralize all control levers and restart the engine. Sany Global.

Before traveling up a steep slope, allow the Sany excavator to warm up sufficiently so that the machine can perform well. When traveling uphill, keep the track in the straight forward direction. When traveling downhill, keep the bucket in the traveling direction and 20~30cm off the ground.

Park Your Excavator Safely in Rainy Season

In rainy days, the heavy rain may cause some geological disasters such as landslide or debris flow. Therefore, we should park the excavator in correct way to protect your safety and property.

Sometimes, the construction work has to suspend due to the heavy rain. Then don’t park your excavator on the jobsite. Transfer the excavator to a safe place. Generally speaking, the excavator needs to work in a place for several days or even longer. As for the most common earthwork, operators excavate the soil from a mountain. It is a very dangerous act to park the excavator on the mountain, since the hillside has been loose and the formal stress structure has been destroyed that is prone to collapse. Especially after the erosion of water, the probability of collapsing has greatly increased. Park the excavator under the tree is not a good choice, since it might be struck by lightning or gale. Then where is a safe place? Choose a solid and firm road to park, such as cement or pitch road. 

The posture of placing an excavator also has a knack. After consulting many experienced operators, the best posture is to stretch the boom and let the bucket grovel on the ground. This posture can best protect the hydraulic cylinder’s core pulling from rains or artificial damage. It is also the best posture to change the hydraulic oil, which can recollect the hydraulic oil to the hydraulic oil tank as much as possible. 

Before you leave the heavy excavator, cut the whole machine’s power supply to avoid the electric leakage. Even though, we can’t avoid some natural disaster, but we can try to avoid the loss through our good habits.
