Dead Weight Direct Residual Shear

Shear unit utilizes dead weight loading system with 10:1 vertical load beam. Digital readout measures shear forces. The vertical and shear displacement is measured with dial indicators 0.5 in x 0.0001 inch resolution and 1.0 x 0.001 inch resolution(12.7 x .00254mm and 25.4 x .0254mm). Optional four channel readout (Model LA-3732-01). Maximum vertical load and horizontal shear force is 1,500 lb (680kg) each.

Maximum shear displacement is 0.8 in (20.3mm). Travel is set with limit switches. Motor drive controls strain rate within 1%, set with digital thumb wheels. Each digit represents 0.0001 in/min (.00254mm/min) strain rate and can be controlled from 0.0001 in to 0.3 in/min (.00254 x 7.62mm/min). Loading and shear box assembly are mounted on a sturdy steel cabinet. Upright rods are made from stainless steel and cabinet has enamel finish. Shear rings and water chamber are aluminum with anodized/ teflon finish for corrosion resistance. Overall height is 54 in (137cm). Cabinet height is 9 in (228.6mm). Length is 36 in (91.4cm). Depth is 14.5 in (36.8cm). Electrical requirements are 110V, 60Hz, 1ph.

Unit includes RS232 serial output cable for sending data to computer; 2.5 in (63.5mm) diameter shear rings, porous stones, drainage plates and water chamber.
