Robust Floor-Mounted DesignWith a stable, floor-mounted structure, the apparatus minimizes movement and vibration, ensuring highly repeatable results. The blue finish adds visual clarity and protection, making it easier to maintain in busy test areas. This design is suitable for long-term use in both academic and commercial facilities.
FAQs of Direct Shear Apparatus Hand Operated:
Q: How is the Direct Shear Apparatus Hand Operated used in laboratory and industrial settings?
A: The apparatus is employed to determine the shear strength parameters of soil by manually applying controlled shear force to a sample. This process is essential for geotechnical analysis in laboratories and industrial quality control environments.
Q: What materials are used in the construction of this Direct Shear Apparatus?
A: This apparatus is constructed from high-quality mild steel, ensuring durability and resistance to wear during repeated manual operations in demanding laboratory or industrial settings.
Q: When should this hand-operated apparatus be chosen over an automatic model?
A: A hand-operated model is preferable in situations where electricity is unavailable or when users seek greater control over the shearing process. It is ideal for remote field labs, teaching environments, or facilities with strict manual testing protocols.
Q: Where is the apparatus typically installed, and why is floor mounting beneficial?
A: The apparatus is designed for floor mounting, providing extra stability during tests. This installation method is preferred in laboratories and industrial sites to prevent movement and ensure consistent, accurate measurements.
Q: What is the process for conducting a direct shear test using this manual apparatus?
A: Operators secure a soil specimen in the shear box, apply a normal load, and manually advance the upper half of the box to induce shear along a predetermined plane. The force and displacement are recorded to evaluate soil shear strength characteristics.
Q: How does manual operation benefit the testing process?
A: Manual operation allows precise control over the shearing rate, reducing test variability and accommodating customized protocols, which is particularly useful for research, teaching, and some commercial applications.
Q: Who can acquire this apparatus in India and what roles do dealers play?
A: Dealers, distributors, exporters, fabricators, manufacturers, producers, retailers, suppliers, traders, and wholesalers across India can acquire and supply this equipment, catering to the needs of laboratories, research institutes, and industrial facilities that require reliable soil testing solutions.
