Our concrete pump clamps are entirely manufactured in Italy, within our own production facilities, using high-quality forged steel to ensure outstanding mechanical performance.
To guarantee maximum safety and efficiency, we carefully select the type of steel according to the required operating pressure. When needed, we apply specific heat treatments to further enhance the mechanical strength of the coupling. Production is carried out using state-of-the-art CNC machinery, allowing us to manufacture clamps compatible with all major connection systems on the market: SK/metric, HD, conical, ZX, and M/F.
We offer a complete range of solutions to meet any operational requirement, including fixed lever couplings, adjustable lever types, one-bolt, two-bolt, four-bolt, and wedge types. Each clamp is treated with cold galvanizing in compliance with ISO 2081 standards to ensure effective protection against oxidation.
Fixed-lever couplings and adjustable-lever couplings are basically interchangeable with each other, their use is the same, the only difference is that one has a fixed and unchangeable clamping (fixed coupling) and the other, having a ‘screw’ inside it, has an adjustable clamping (adjustable coupling). Concrete pump arms normally have fixed lever clamps so that the operator does not have the option of loosening them.
Safety pins are applied in the coupling closure to prevent accidental opening and comply with the CE standard EN 12001, which makes their application mandatory.
All of our couplings have internal testing. Testing is carried out at a certain frequency, which is specified by our ISO 9001: 2015 quality management system. We define the breaking point by doing sample tests where the joint is initially brought to a pressure of 85 bar and after 10 seconds, we gradually increase the pressure (by 10 bar every 10 seconds) until we reach the breaking point. Example of one of our test and inspection certificate.
