About This Product
In the field the jack drives the 50 mm penetration piston into the soil, with the extension rods acting as spacers between proving ring and piston and the surcharge weights placed around it. Penetration is read on a dial gauge whose support clamps anywhere along the 2 m bridge, while the chosen proving ring shows the load.
Frequently Asked Questions
Which proving rings come with the Field CBR Equipment?
Proving rings of 10 kN, 28 kN and 50 kN capacity are listed, along with a penetration dial indicator.
What are the extension rods for?
Machined from steel tubing in lengths of 5, 10, 30, 50 and 100 cm, they act as spacers between the proving ring and the penetration piston.
Is a dial gauge included?
A 0.01 mm x 25 mm dial gauge is listed as an accessory, used with the dial gauge support on the bridge.
