Hi, 

This is Simon again.

Here is a short introduce of double lane tripod turnstile.

Then he looked behind him and saw that no land was visible.

Double lane design, for in&out people counter.

Manual push arm to pass lane.

Inner mechanism with hydraulic buffer, tripod arm with a hydraulic pressure locked in middle status after people pass the gate.

Advantage of hydraulic buffer mechanism, quietly, runing smooth.

the old man thought that a gaff and a harpoon were needless temptations to leave in a boat.

If there any projects, welcome to contact with me any time.

There were other boats from the other beaches go ing out to sea and the old man heard the dip

Best regards.

Simon
