Seat Belt Webbing Tensile Strength Testing Machine

Floor-standing tensile machine with wedge or capstan grips for breaking strength and elongation of vehicle seat belt webbing. Used by belt weavers, automotive restraint suppliers and homologation test labs.

Specification

This machine pulls seat belt webbing to rupture and records breaking load and elongation on a digital controller. Capstan grips prevent slippage and jaw breaks on high-strength polyester webbing, giving repeatable results for incoming inspection and type approval work.

Features

• Capstan or wedge grips for slip-free gripping of woven webbing
• Servo-driven crosshead with stepless speed control
• Load cell with 0.5 percent accuracy over 10 to 100 percent of range
• Peak load, elongation and breaking strength printed per specimen
• Rigid dual-column frame with limit switches and overload cut-off
