The gearbox rack and pinion are fixed on two upright pillars and the movement of the rack is guided by a bracket and two pillars. The loading is done hydraulically. Two pressure gauges 15cm dia. One of Low capacity o-60kg/sq.cm.in 0.5kg/cm/sq. divisions and other 0-160kg/cm.sq are provided to indicate the penetration resistance. Isolation valve is provided to automatically isolate the lower range gauge when it reaches the maximum capacity. The valve can be adjusted and locked at desired values between 20 to 60kg/cm.sq. Provision is made to anchor the unit at site and there is provision for lateral shifting so that subsequent tests could be performed without having to shift the entire anchorage system.
