1、 Overview of this device:

The drop testing machine is specifically designed to test the damage of product packaging caused by falling, and evaluate the impact strength during transportation and handling. It uses a brake motor and chain transmission to drive the drop arm to extend and lower. The drop height is used in a digital height gauge, with precise drop height, intuitive display, simple operation, smooth lifting of the drop arm, and small drop angle error. This machine is suitable for various manufacturers and quality inspection departments.

2、 Design applicable standards:

ISO 2248 JIS Z0202-87 GB/T4857.5 GB/T3873-1983 GB/T2423.5 and other standards

3、 Experimental principle:

Lift the test sample to the predetermined height, then let it fall freely in the predetermined state and collide with the impact table.

4、 Main technical parameters:

1. Power supply: AC380V 50HZ

2. Power: 1.85KWA

3. Drop height mm: 300-1500 (height can be set arbitrarily)

4. Measure maximum weight kg: 80Kg;

5. Bottom plate thickness: 10mm

5. Maximum size of specimen mm: 1000 (length) * 1000 (width) * 2000 (height)

6. Impact panel size mm: 1700 (length) x 1200 (width) x 10 (height)

7. Drop height error: ± 10mm

8. Test bench dimensions mm: approximately 2000 x 1200 x 2315

9. Net weight kg: approximately 300kg;

10. Test method: drop from all directions of face, angle, and edge

11. Control mode: pneumatic drop mode, electric reset.

12. Falling height error: 1%

13. Parallel error of the striking panel: ≤ 1 degree

14. Error in angle between the falling surface of the specimen and the horizontal during the falling process: ≤ 1 degree

5、 Precautions and maintenance

1. The shell of the testing machine must be reliably grounded, otherwise there is a risk of electric shock;

2. The power input terminal should be connected with air switches and contactors with leakage protection of the same capacity or higher, so as to immediately cut off the power supply in case of emergency;

3. When the machine is running, do not touch parts other than the control panel with your hands to prevent scratches or squeezing;

4. If you need to move the machine, be sure to cut off the power and let it cool for 5 minutes before operating.

5. After the installation of the new machine at the factory is completed, it is necessary to add appropriate low concentration engine oil at the sliding rod. It is strictly prohibited to add rust proof oil or high concentration engine oil, as well as accumulated corrosive oils.

6. If there is too much dust at the oiling area for a long time, please lower the machine to the lower part, wipe off the previous oil, and then re oil it; Regularly add lubricating oil to the transmission components of the machine;

7. The drop machine belongs to mechanical equipment with impact force. When a new machine is used more than 500 times, all screws must be tightened once to avoid failure.
