Pendulum impact test instrument
I. Product Overview:
The device conforms to the requirements of GB2423.55-2006, GBT20138-2006, IEC61439-1:2009, IEC62262-2002 Article 6 and IEC60068-2-75 and other standards for test equipment, and is suitable for the mechanical impact strength grade test of electrical equipment shell to the outside world. The device adopts stainless steel frame welding forming, compact and durable structure, adjustable up and down mounting bracket, adjustable impact Angle 0-90°, easy to operate.
Mainly used for JP cabinet, low-voltage switch cabinet, cable branch box, meter box, lamp type shell and other products mechanical crash test, through the replacement of different types of hammer head to achieve a variety of energy crash test. The device has the advantages of simple operation, convenient use, quick installation and so on.

7, the installation of intelligent anti-secondary impact device: the use of solenoid valve control, automatic release of the pendulum rod, when the hammer hit the sample, in the hammer back, the infrared automatic sensor will issue instructions to fix the hammer head, so as to avoid the hammer head on the sample of the secondary impact.
8, remote control: This device is equipped with remote control equipment, lifting, releasing pendulum rod can be remote control, the operation is quite convenient, more secure for life safety.
