Movable tunnels

Kopron movable tunnels can be fixed, retractable, extendable and spiral sliding.

Fixed tunnels are anchored to the ground using anchor bolts or foundations, or by less invasive methods such as ballasts.

The structure of the movable tunnel can be retractable or extendable: forged steel wheels are added to the beams that rest on derailment rails. Kopron retractable covers are designed to wrap around themselves, making the underlying space completely open or closed, as needed. With simplicity, you can move the steel shed both manually and with the help of automatisms such as powerful motors. The entire retractable tunnel, once packed, occupies only 1/3 of the total length, optimizing the available space.

A movable tunnel can become sliding thanks to installed motorization. The entire structure can be operated and run horizontally on rails, without altering in any way the activities that take place underneath.

Movable spiral tunnels are characterized by a structure that opens and closes like normal retractable tunnels and a part that rotates like a spiral to follow irregular curves or trends. This particular type of steel shed is mainly used in logistics and freight loading areas to isolate and protect loading and unloading. The tunnel is covered by a PVC sheet and consists of a load-bearing structure made of hot-dip galvanized steel arches with wheels that rest on the ground. The arches are connected by scissor bars that allow rotation at 30/45/60/90 degrees to the right or left, to allow the loading/unloading of vehicles.
