Safety Helmets Lateral Rigidity Tester
The Safety Helmet Lateral Rigidity Tester is designed to evaluate the lateral deformation and resistance to sideways loading of safety helmet shells. It applies a controlled lateral force to a helmet and measures the resulting displacement, providing quantitative data for helmet performance evaluation and quality control.
The instrument features an electromechanical loading system with a maximum force capacity of 1,000 N and a displacement measurement resolution of 0.1 mm. Its adjustable clamping system accommodates different helmet sizes, while real-time force and displacement displays support convenient monitoring during testing.
The system includes automatic data recording, peak-force display, and software-based result export. Safety functions include emergency stopping, overload protection, and a clamping interlock. It is suitable for helmet manufacturers, testing laboratories, and product development facilities.
Application
(1) Industrial safety helmets.
(2) Helmet shell lateral deformation testing.
(3) Safety helmet design and material development.
(4) Incoming inspection and production quality control of safety helmets.
(5) Laboratory evaluation of helmet resistance to lateral loading.
