What is blank hit ? And advantages and disadvantages of the design to prevent blank hits.

In addition, kraft paper material also has aesthetic appeal. Although it may appear simple on the surface, kraft paper can present exquisite patterns and text through printing, hot stamping, and other techniques, enhancing the overall quality of the product. At the same time, the natural and rustic color of kraft paper gives people a sense of familiarity and is more easily loved by consumers.
In summary, the use of kraft paper for nut packaging bags has multiple advantages such as environmental friendliness, strong durability, high aesthetics, and low cost, making it an excellent packaging material.What is a blank hit?
The chisel does not have enough downward pressure on the crushed object when the BREAKER is started.
The piston cannot fully hit the chisel or does not hit it at all, causing the piston to directly hit the front body.

1.The main reason for the blank hit?
→ The driver is not paying attention and lacks experience
→ Poor working conditions
The excavator is working under unstable conditions
The crushed object shakes,causing the chisel unstable (when hitting small objects)
The operator cannot see the crushed object (underwater operation)
The chisel cannot fully press the work under the chisel state. (Floor, tunnel operation)
When the BREAKER cannot operate vertically (side tilt strike...)

2. Breaker failure caused by blank hit
→ Through bolt breaks
→ Rod pin breaks
→ Chisel breaks at the pin
→ BRACKET breaker parts are damaged

3. Blank hit
Empty strike is the cause of fatal equipment failure, so our company has used blank hit prevention technology on HMB1400 breaker.
In order to prevent the operator from continuous blank hit, a system is specially designed to shut down after one blank hit.
That is, the design that the chisel cannot hit when there is no object to be broken can prevent multiple consecutive blank hits.

4. Advantages and disadvantages of the design to prevent blank hits
1) Advantages of the empty hit prevention performance
Prevent the phenomenon that causes fatal failure of the equipment, reduce the damage rate of components,and extend the service life of the equipment.
2) Disadvantages of the empty hit prevention performance
(1) In general, the incidence of blank hits caused by pressing down on objects to break is high,
Continuous blank hits are relatively rare.
(2) When the blank hit occurs during operation, it becomes very difficult to introduce the blank when preparing for the next hit,that is, a very large downward force is required to make the chisel enter.
(3) In places with very poor working conditions (conditions where the excavator cannot be operated stably or the breaker cannot operate vertically),the phenomenon of being unable to perform the initial hit occurs.
(4) In a low-temperature working environment below 0°C (when the oil temperature is extremely low), it is not possible to fully test run the machine, and it becomes very difficult to introduce the chisel.

Customers can choose whether the breaker has a anti-blank hit function based on their own working environment.
