SKL-TX weighing devices consist in Crosby Standard complying Shackles including radio transmission circuits, batteries and antenna. Extremely rugged, they have been specifically designed for hard environment use and avoid any wire connection for load measurement transmission. SKL-TX Shackles are user friendly for immediate use on lifting machines like knuckle boom cranes, over-head cranes, etc., providing excellent accuracy. The sensing element replaces the standard pin of the shackle in order to get a direct reading of the load weight. A tight box is connected to the Load pin, where easy to replace alkaline battery is fitted. This load measuring device can be radio connected with 3B6 LMI's or to SKL-RX portable receivers.
