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.

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.

Hydraulic Excavator is in Short Supply in the Golden September

Recently, the China Construction Equipment Industry Association issued hydraulic excavator sales data of September, which showed the dynamic of China excavator market. The good situation in the excavator market makes solid foundation for the recovery of the construction equipment industry. With excellent performance, Sany excavator is in short supply and achieves the market leadership.

It is reported that Sany sold 1114 units of hydraulic excavator in this September, achieving 99% year-on-year growth and ranking No.1 in the industry. In the first three quarters, Sany excavator is in the first place with the sales volume of 9934 units. Sany also ranks NO.1 in excavator exporting with the amount of 2053 units. Barring unanticipated circumstance, Sany will become the double-champion in domestic excavator sales and export sales of China.

In September, the China excavator market is very lively. 2792 Units of small excavator weighing less than 13 tons are sold, accounting for 51.17%, the sales amount of medium excavator (13 ton-30 ton) is 2015, accounting for 36.93%, the sales amount of large excavator（more than 30 tons）is 649, accounting for 11.90% of the total excavator sales. Comparing with the sales amount of 2015, the sales volume of hydraulic excavator has achieved 60% year-on-year growth, especially the large excavator has achieved double growth. Under this hot selling background, Sany small excavator and medium excavator rank NO.1 with the sales amount of 672 and 403, Sany large excavator ranks NO.2 with the sales volume of 84 units.
