Excavator used in Land and Water

As the world leading construction machine manufacturer, Sany produces excavator with advanced technology and super design, which can be used in the toughest working environment. Sany digger adopts Dynamic Optimized Matching Control System, short for DOMCS, which injects new technology into power system, control system, hydraulic system and structural parts. The new technology makes great breakthrough in improving working efficiency, reliability and reducing fuel consumption, thus making the machine possess the features of high durability, high efficiency, long service life and strong adaptability.

Generally, excavators are used in the land, but with excellent research and development ability, Sany manufactured one that also can be used in the water. Refitted from the crawler digger, the amphibian excavator can be used in land, shallow waters and deep waters, which expands digger’s working range to aerostation and dredging. This refitted digger uses crawler belt with double-boat form buoyancy tank structure and sealed crawler board in box shape, ensuring stability and safety working in water. The strengthened working devices and swift rotary structure improves working quality and efficiency. The spacious cab with humanized and practical interior accessories provides the operator a safe and comfortable operating experience. 

The amphibian excavator can be used in resource development and environment renovation like improvement in rivers, lakes and seas, which not only save human labor but also improve working efficiency. Committing to making more contributions to social development and creating the maximum benefits for customers, SANY will manufacture more innovative products in the future.

Excavator Operating Techniques

When operating excavator, we should pay attentions to the around environment like the barriers and terrains. Pay attentions to the crawler belt to avoid collision or tipping over. Make both of the crawler belts completely touch with the ground to improve stability. The digging power is the maximum when the angle between the bucket cylinder and the rod is 90°. The cutting power is the best when the angle between the bucket teeth and the ground is 30°. The bucket rod working angle should be kept between 45°in the front and 30°in the back. And it can improve the digging efficiency when use the arm and the bucket at the same time. excavator for sale.

The large and hard rocks will damage the bucket, so some techniques should be mastered when digging in the complicated terrains. The machine body should be positioned towards the cracks of the rocks and make sure that the bucket teeth can easily insert the cracks. Only when the rocks are crashed can the excavator starts to dig. When leveling the slope, the excavators should be positioned stable and balanced. And the arm movement should be accordance with the rod movement, which is very important for the slope leveling.

When it refers to loading and unloading, good cooperation between the truck and the digger is very important, which means that the two machines should make consistent action. Both of the machines should be kept stable, otherwise, it will be hard to control the rotation and extend the working time. The hydraulic excavator should keep proper distance with the truck to avoid any collisions during the working process. Generally, the truck should be positioned lower than the digger, which can shorten the arm lifting time and provide a good vision for the operator. According to the loading experience, the sand and rubbles should be loaded before loading the big rocks, which can effectively reduce the collision to the carriage.
