We are one of the leading manufacturers and exporters of laboratory vane shear that is widely used for finding the shear strength of a given soil specimen. This electrically operated equipment has a rotating speed of 1/60 r.p.m. With the assistance of this equipment, the measurement of shear strength of cohesive soils can be easily done. This is useful for soils of low shear strength (less than 0.3 kg/cm2) for which triaxial or unconfined tests cannot be performed. The test gives the undrained strength of the soil. The undisturbed and remolded strength obtained are useful for evaluating the sensitivity of soil.

Specifications:

• The Load Frame consists of a cabinet which houses the gear system and motor with sturdy angle iron frame

• The loading is done through the bottom loading platen, which is carried on a lead screw, which advances upwards. The top load bracket, which slides over two upright pillars, can be positioned at any desired height and locked. It carries a screw adapter for standard proving rings

• The loading part of the unit is detachable from the main unit for ease of transport and to avoid damage to the tension rods

• Rates of strain: 30, (between 6 mm / min and 0.00048 mm/min.) By interchanging the drive and driven gears, another set of 24 rates of strain can be obtained

• Suitable for operation on 230 V, 50Hz, single phase
