Zhuozhou Tianpeng Imp. and Exp. Trade Co., Ltd. is one of the leading manufacturers and suppliers of direct shear apparatus in China. With abundant experience, we warmly welcome you to buy customized direct shear apparatus made in China here from our factory. Quality products and reasonable price are available.
Description of Product
This stand-alone model features microprocessor control and a high-resolution stepper motor with epicyclical reduction gear for reduced backlash. A pneumatic closed-loop system with high-performance pressure regulator automatically applies axial pressure, removing the need for manual dead weight loading. The shear box carriage is constructed from high-quality technopolymeric material, providing excellent resistance to corrosion, wear and chemicals. It is lightweight and easy to clean.

Features
● 3600r/min for efficient solvent extraction.
● Microprocessor-based "Automax" control unit with scratchproof polycarbon front panel and graphic display.
● Comes with bi-directional load cells (5KN, ±0.15% accuracy) and high-resolution displacement transducers (0.001mm resolution).
● Automatically applies unlimited preset consolidation steps and manages test progression until failure.
Eliminates need for heavy dead weights and balance lever arm, with vertical force applied directly without friction.
● Supports multiple shear speeds and reverse travel for residual shear tests.
● Axial force can be applied instantaneously or via linear ramp over preset time.
● Independent data recording modes for consolidation and failure stages.
● RS232 serial port for data downloading.
● Brass shear box assemblies with rigid walled square or round hole, includes loading pad, retaining plate and porous stones.
● Software modules include acquisition, consolidation, standard shear, quick shear, with optional repeated shear and post-processing.
Accessories
All shear box assemblies are constructed of brass and are designed to contain water that surrounds the specimen. They consist of a square box with a rigid walled round or square hole complete with adapter loading pad, retaining plate, 2 porous stones.
