Applications of Compact Excavator

With the demand for infrastructure construction increasing and the manufacturing techniques improving, compact excavator has wider applications and becomes a common sight in the construction site. The small digger can be widely used in house building, railway construction, port application, mine exploring and other engineer constructions for digging, trenching, grading and more.

As the world-leading construction machinery manufacturer, Sany produces advanced products with top quality, ease of operation, high flexibility, low fuel consumption and considerate service delivery. Sany compact excavator is reliable enough to handle various constructions in different climate, terrains and working conditions, its powerful working capability wins high recognition from the customers all over the world.

With the demand for houses building increasing, the need for construction machines will also increase, especially the digger. Being compact and flexible, the compact excavator can be used in narrow space where the large machine could not reach. Maintenance should not be neglected, which is very important to keep the machine in a good condition to reduce downtime and catch the working schedule no matter in what kind of constructions. Lubrication is a key step in the digger maintenance since the lubricant can reduce abrasion to the machine. The lubricant should be kept clean to avoid mixing with dust, sand, water and other impurities. Proper lubrication can extend your machine’s service life and reduce maintenance cost, which plays an important role in the digger applications.

Excavator Road Building Techniques

Excavator is widely used in road building. Mastering some techniques can not only improve working efficiency but also reduce damage to the machine. When digging, the angle between the boom and jib should be 90°to 110°and the angle between the bucket’s bottom and the ground should depend on the quality of the earth, 60°for soft earth and 30°for hard earth. The boom will cooperate with the bucket movement under the driving power of the cylinders on the jib. The bucket should be taken back when it is filled with three quarters by lifting the boom.

Leveling is a step that integrates with varied movements in digger road building, which includes digging, sweeping and positioning. The earth in the high place should be moved to the low place, the earth in the surface should be taken first then the subsoil followed. To dig a trench, the two sides should be excavated before the middle place. The digger should be kept stable and the crawler belt should travel straight line, which is very important for digging a straight trench. The trench should be dug gradually by making perfect and accurate work in each section, which will ensure the finished trench does not require remedial work to make it usable. 

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. Don’t make sharp turns at high speed, which is very dangerous. The compact excavator should be maintained regularly to avoid break down to the minimum and guarantee the work finished on schedule.

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.
