Economical and practical construction method

1. The bucket should be filled with loads

At the beginning, use the power of the bucket to dig, then make the bucket teeth face the digging direction, control the operating lever to dig shallowly with full stroke, and the bucket can be filled cleanly. At the end of digging, quickly convert the action of retracting the bucket arm to extending the bucket arm. At this time, the sand and soil gathered at the bucket teeth will fall on the inside of the bucket, which will have the effect of leveling the sand and soil, so that the sand and soil can be prevented from falling out through the "shaking operation".

2. Choose the digging angle according to the soil conditions

Choose the digging angle of the bucket according to the hardness of the soil. For soft soil, increase the digging angle, dig deeply, and end the digging in a short distance. For hard soil, reduce the digging angle to reduce the digging resistance. However, for hard soil that is difficult for the bucket teeth to bite into, if the digging angle is increased, digging will become very easy.

3. Effective use of digging force

Generally speaking, it is the most effective method to dig within a range of 65° between 50° forward and 15° inward with the bucket arm perpendicular to the ground as the reference to make the bucket reach a full shovel.

4. Postures that require strong digging

The digging force mainly utilizes the traction force of the bucket arm and the digging force of the bucket. The maximum digging force is exerted when the bucket arm pin and the bucket arm cylinder are at 90°.
