Sure Grip Belt Clamps

Sure Grip belt clamp Patent No. PP0029

The Sure Grip® belt clamp can apply positive pressure in excess of 6 tonnes directly to the surface of any belt width while having a pulling ability in excess of 10 tonnes and when linked in tandem can exceed 16 tonnes. With a checker plate finish applied to the gripping faces of the beams together with the screw jacks applying in excess of 6 tonnes, maximum grip is assured.

Generally, bolts, nuts and washers on conventional clamps get lost or damaged. The Sure Grip® belt clamp is more robust and the bolt is not removed from the clamp, thus minimising damage and/or loss.

The clamps have been extensively tested on a tensile test bed capable of 200 tonnes line pull. Our test results have proved that a Sure Grip® belt clamp on a 1m wide 1000kN belt will handle 5 tonnes line pull comfortably while a conventional belt clamp will start showing slippage with a 2 tonnes line pull. Engineers reports and observations are available on request. Safe working loads for the belt clamps have been calculated from results.

Our larger models are fitted withratchet winches at both ends to enable easy raising of the lower beam even when the belt is in a trough position.

Calculation on belt clamp requirements can be obtained on submission of clients belt details. We can also supply made to measure wire, nylon or chain slings and with double lug for linking in tandem.
