Crosby clamps designed to avoid wind component damage

11 June 2021

Oklahoma, USA-headquartered rigging, lifting, and load securement hardware specialist The Crosby Group (Crosby) manufactures a range of lifting clamps designed for applications in the wind industry.

The company said that a common problem when handling steel plates with lifting clamps is that the clamping camsegment and pivot can leave an indentation in the material surface, known as marring. These indents then have to be ground away from the surface costing time and money. 

How Crosby’s lifting clamps avoid damaging wind components

According to Crosby its CrosbyIP-branded standard and custom vertical and horizontal lifting clamps are designed to avoid this by reducing the height of the teeth of the camsegment and pivot. This means that the pitch between the teeth can be decreased and more teeth can be in contact with the material surface, reducing the depth of the indentations, Crosby explained.

CrosbyIP vertical lifting clamps have been made with welded alloy steel bodies to minimize size but increase strength and alloy components are forged, where required, the company said. The clamps have a lock open, lock close function with a latch for pretension and release of material. Each product has its own serial number and proof load test (to two times working load limit), date stamped on the body, and a user manual with test certificate included with each clamp. Its clamps are ISO 9001 certified, and RFID equipped.
