Hydraulic Excavator for Construction Applications

The hydraulic excavators are designed for various operation uses, such as excavating, leveling, digging, loading and demolishing. Commonly used in construction, road building, mining, and civil engineering projects, the hydraulic excavators are applicable for various operations. Backhoe operation of hydraulic excavators is suitable for digging an area which is lower than the excavator. When the hydraulic excavator’s boom cylinder is at 90-degree angle while the arm cylinder stays vertically, maximum digging force can be obtained through the thrusting force of each hydraulic cylinder. Make use of this angle effectively to help you achieve the maximum working efficiency of the excavator. The digging range of the hydraulic excavator’s arm is from 30 to 45°. The angle may vary according to digging depth, but it is better to keep it within the above range if possible. Do not operate the hydraulic cylinders to their full.

You can use the hydraulic excavator to dig a trench efficiently by installing a bucket suitable for this job and adjust your excavator tracks to parallel the to-be-dug trench line. When digging a wider trench, excavate first both sides of the trench and then remove the middle part. In excavating operation, the excavator track should be adjusted vertical to road shoulder or cliff, with sprockets behind the excavator cab, so that the hydraulic excavator can retreat easily in case of an emergency. For excavator loading operation in a place where the swinging angle is small, working efficiency can be improved by parking the dump truck at where the excavator operator could see easily. It is more convenient for the compact excavator to load more material if the dump truck is loaded from rear rather than from its sides.
