Static Cone Penetrometer Hand Operated

The drive is by means of a rack and pinion manually through a gearing arrangement. The gear box and pinion are fixed on two handles, sprockets and chain arrangement. The movement of the rack is guided by a bracket ( attached to the rack) and two pillars. The penetration resistance i.e. the pressure is indicated on hydraulic gauges through a hydraulic measuring head. Two pressure gauges of 15cm dia dial and 2 capacities 0-160kg/cm are provided. An automatic cut-off valve, to protect the low capacity gauge from being overloaded is provided. The 2 valve can be adjusted and locked at desirable values between 20 to 60cm . A provision is made to anchor the unit to the ground (with the help of four anchors supplied with the unit) and there is a provision for lateral 2 movement of the unit so that subsequent tests could be performed without shifting the entire anchorage. A 10cm penetration cone with friction jacket is provided along with fifteen mantle tubes (non-uniform having an effective length of 1 m each with sounding rods for finding out the cone (point) resistance or jacket friction.
