Break-away coupling improves safety during tanker loading
Emco Wheaton
The TODO TTMA 4-in. Aluminum Break-Away Coupling (photo) is designed to reduce the potential for damage and spillage and product loss during the loading and unloading of road tankers. The device has been adapted for bottom-loading-arm applications, and it can be used on new loading arms, or retrofitted into existing ones that currently use the same type of TTMA flange in their construction. It consists of two identical halves joined together by a series of 3-mm break pins allowing the device to be configured to separate at a defined load. Should an excessive load be placed on the loading arms, the pins automatically close the internal valves, to protect the driver and the environment. The device can then be reset onsite. — Emco Wheaton USA, Houston
