A system for holding down underground storage tanks, such as fuel tanks at petrol stations, wherein the tank is tied down to anchors buried with the tank using straps. In order to tension and clamp the ends of the straps a clamping axle is used atop the tank which, when rotated, tightens the strap. The clamping axle is then locked into position and buried with the tank. Apparatus are provided to facilitate tightening of the clamping axle and to lock it into place once the strap reaches an appropriate tension. |
