HRG-815B safety helmet chin strap strength lateral rigidity tester(Electric)

purpose

According to GB/T 2811-2007 and GB/T 2812-2006The development and production of safety helmet standards are used for testing the lateral pressure resistance (lateral rigidity) performance of safety helmets and the strength of chin straps. One device can achieve two testing functions.

HRG-815B safety helmet chin strap strength lateral rigidity testerfeature

Test procedure	The experimental process is electrically operated, with stable force application and adjustable speed ★ (better than manual force application, making the experiment more accurate and easier)
host	★ Host: Adopting a control box and operation platform upper and lower structure design, it effectively solves the problems of displacement rod not being in a straight line, inaccurate distance display, and jamming caused by the lever principle when the lever rotates in similar instruments on the market (most of which use left and right structures of control boxes and operation platforms). ★
Function switching	Switching between chin strap strength testing and lateral rigidity testing functions can be completed without switching test fixtures, making it easy to operate (eliminating the need to replace test fixtures) ★
Sample clip	Sample clamp: made of 45HRC material stainless steel metal sample clamp
test system	Testing system: capable of displaying real-time testing force values; Automatically save power values
head model	Head mold: equipped with 1 # and 2 # head molds, connected to high-precision force sensors
Displacement distance	Displacement distance: high-precision ranging device is used to display the distance between two plates in real time, with a resolution of 0.1mm
Limit function	Limit function: equipped with upper and lower limit warning devices to avoid damaging the distance measuring device when reaching the upper and lower limits ★
timer function	Timing function: using domestic brand time relays to record test time with a display accuracy of 0.1s
