One person can operate the whole handling system. No need to walk back to open a sliding gate.
This guillotine-style tail gate is operated from anywhere along the side of the Squeeze Crush by pulling a rope. Lay it on top of the beast’s tail head as she passes through and it drops, locking out the beast behind. It can be locked in the raised position if desired. The advantage of this system, as opposed to a sliding gate, is that one person can operate the tail gate, head gate and squeeze mechanism without leaving the front of the Squeeze Crush. The aluminium tail gate is to high tensile aerospace specification, which is 35% of the weight of steel.
