Rugged Crocs are designed to anchor cables in the ground. The combined mechanical resistance of the cable and the Croc system makes it virtually impossible for the cable to be pulled from the ground. The secret lies in the combined resistance of each individual Croc over the length of the cable.
Taking soil type into consideration, the average resistance one Croc will deliver is estimated at 1 ton per Croc. When 10 metres of cable is fitted with 10 Cable Crocs (1 Croc per metre) the combined resistance needed to pull the cable from the ground is 10 tons. If this figure is extrapolated over the length of a 100 m cable it results in 100 tonnes of resistance.
The installation of Rugged Crocs is fast, simple and requires no specialised skills. The correct size unit (25 mm; 50 mm; 95 mm) is simply strapped to the cable by using four industrial strength cable ties at one metre intervals. The fitted cable is then placed in the prepared trench, covered with soil, and compacted.
