Hand Vane Shear Apparatus

The Hand Vane Shear Apparatus is used for rapid in-situ determination of the undrained shear strength of cohesive soils. This portable device is essential for geotechnical engineers conducting field investigations, particularly in shallow excavations and boreholes.
The apparatus operates by inserting a vane into the soil and applying torque until shear failure occurs. The resistance to rotation is measured, providing a direct assessment of the soil’s shear strength without the need for sample extraction.
Equipped with interchangeable vane adaptors, the device accommodates a range of soil strengths, from very soft to stiff clays. This versatility ensures accurate measurements across diverse site conditions.
The compact and lightweight design facilitates ease of transport and operation, making it suitable for both field and laboratory settings. Its straightforward mechanism allows for quick deployment and reliable results.
When used in conjunction with other soil classification tests, the Hand Vane Shear Apparatus contributes to a comprehensive understanding of soil behavior, informing design decisions for foundations, slopes, and earthworks
