The Agr International Vertical Load Tester 3 (Model: VLT3) is 100% designed, engineered, and manufactured in the United States by Agr International, Inc. – the internationally recognized global benchmark in container inspection, dimensional metrology, and physical strength testing instrumentation. Representing the latest evolution in Agr’s storied lineage of advanced force testing equipment, the VLT3 delivers an advanced laboratory and at-the-line testing platform engineered to assess the axial compressive strength of commercial glass packaging.

At the technological heart of the VLT3 is a high-precision industrial hydraulic loading system capable of applying vertical compressive loads up to an impressive 2,070 kg (5,900 lbs / approx. 20.3 kN) with smooth, linear force ramp-rates. The instrument accommodates two standardized industrial testing methodologies:
1. Pass/Fail Proof Test: Applies vertical force to a pre-selected threshold and dwells to verify structural container integrity without inducing failure, simulating the acute mechanical loads applied by high-speed crown corking mechanisms or ROPP capper spindles.
2. Test to Destruction: Continuously increases axial force until total structural collapse occurs, automatically capturing peak crushing force data to establish catastrophic failure envelopes.

A defining operational advantage of the Agr VLT3 is its native compatibility with Agr’s Ramp Pressure Tester 3 (RPT3): all vertical load test data, recipes, and statistical parameters can be centralized, managed, and displayed directly on the RPT3 color touchscreen user interface. Operators can initiate test routines either via local pushbuttons on the VLT3 chassis or remotely through the primary RPT3 control console, with full user-selectable force units (lbf, kgf, Newtons). Constructed from heavy-duty, corrosion-resistant stainless steel and outfitted with an electromechanically interlocked safety access door, the VLT3 guarantees total operator containment during explosive glass fracture events. The Agr VLT3 serves as an indispensable physical strength evaluation standard for commercial glass container manufacturing plants, major brewing and beverage packaging facilities, and container lightweighting research suites worldwide.
