The Loading Arm Luffing Switch permits loading only when the arm is in the correct downward position, that is, at 10° below horizontal. It therefore prevents loading operations unless the loading arm is in the working position. By changing the switch position, it is possible to get the signal to operate when the arm in the upper/parking position.
It can be used on both top or bottom loading arms.
We can offer loading arms equipped with electrical components to signal many different positions or conditions. Signals can be given with the use of either electro-mechanical microswitches or proximity switches. Both types of switches have ATEX certification.
