The knowledge of hammer hammers is known to excavators

For the excavator hand, the excavator hammer is the most commonly used device to remove the excavator bucket. But how much do you know about this device? Here's the little book, and I'll tell you about the hammer.

First, different conditions using different steel

1, flat steel is suitable for medium hardness: broken stones or rupture of small stones, the last step is smaller.

2, a steel prefix: suitable for all kinds of soft and neutral stratification digging, trenching work.

3, cross head steel: suitable for fine and neutral concrete and soft non layered rock.

Second, how to replace steel

1, remove the retaining pin and 330mm long steel pin, re installation of the drill rod is placed after the insertion of the drill rod pin;

2, re install steel, to remove the reverse order, should first check whether all parts of the wear and tear.

Such as steel deformation, should be polished after the repair, the steel pin and steel moving parts coated with oil, then the installation of steel;

If the steel pin deformation is serious, will bring difficulties to the replacement of steel, so every 100-150 hours of operation, should be checked!

Third, how to properly use steel work

The drill rod and the small arm direction should be consistent, and the surface of rock drill rod should be vertical. If the surface of steel and rock is not vertical, during operation, the drill rod may slip. When broken, the drill rod fully adjusted, in a stable condition, click Select rock impact work.

Four, remember the precautions

1, the use of appropriate downward force can improve the efficiency of broken hammer.

2, before leaving the equipment, to reduce the arm, to confirm whether the equipment is in a safe state.

3, don't use steel as a lever.

4, crushing shall not continue in the same position as a lasting work in the same position, will make the steel temperature rise, lower hardness, the steel is rolled up, thereby reducing the work efficiency.

5, in the water device, prohibit the operation of water:

No part of the hydraulic breaker shall submerge into the water prior to the operation of the equipment in the unallocated water;

When using hammer in water, we need to equip with water equipment and air compressor which can produce 6000LPM/150PSL;

(Note: in the absence of water equipment and air compressor in the case of water operation may cause damage to the hammer inside

6, adjust the hammer position - crushing hammer operation can not crush the rock, should be moved to a new job location.

Five, when the replacement of the new steel.

The use of steel long time will cause lower roll deformation, if the drill rod end is worn, steel is easy to slip, the drill rod to end grinding sharp, after repeated grinding will reduce the hardness of steel. If the distance between drill rod and the guide sleeve is too large, the piston cannot accurately strike drill rod damage. If the distance is more than 9mm it should replace the drill rod and the guide sleeve.

Some users never maintain and maintain the broken hammer, which is a wrong way, of course, except for money and self willed. A good maintenance of the broken hammer will also help your machine life.

The above is about excavator hammer related knowledge, hope to help everyone's work.
