Mobile Tunnels Mobile Tunnels are the ideal solution to cover and protect goods and people. Composed of galvanized structural steel modules, the tunnels can be used to cover large surface areas in little time. Being mobile, they can often be installed without the need for a building permit. Available in a wide range of solutions and geometries, they ensure a highly agile response to most customer needs. A minimum of construction work, and your industrial shed is ready!

Mobile Tunnels The combination of a sturdy material like steel and an equally sturdy flexible cover allows the design of highly customized structures that can be completed in very short times and cover extensive surface areas. What you have in mind can often be built with unthinkably low amounts of time and cost using a mobile tunnel.

Mobile Tunnels The mobile tunnel framework is made of strong galvanized rectangular sections joined by bolts with the aid of appropriate ribbed steel plates. A tight trestle forms a sturdy framework around which the cover will be then securely attached. Over 90% of the tunnel is bolt-assembled; this method provides a number of advantages compared to traditional welding, including certainty of resistant sections, modularity in transport, and interchangeability of damaged pieces. Nearly all models and types in the catalogue are equipped with heavy duty wheels for manual or motorized movement:...

Mobile Tunnels The framework is covered with a heavy duty PVC-coated polyester fabric with self-extinguishing properties (class 2 or optionally class 1). Colours and silk-screen printed designs according to customer specifications. The cover surface can be standard, insulated for condensate resistance, with a double sheet applied below the tie beam, or made of rigid insulated panels. For every need the right solution

Customized cover

Mobile Tunnels Cut-to-measure sizes From small tunnels to large mobile sheds. Custom width, height and depth sizes available on request. Standard width

Mobile Tunnels Installation details and accessories Floor mounted guide The HFR and HLT models require a floor mounted guide, which can be installed directly flush with the floor (A) or on a raised guide base (B). Pillar with anchor bolts HLT, HTT and HPN models required the floor mounting of anchor bolts on which the pillars will then be based

Sliding curtain detail The sliding curtain is an optional element to close the open sides of the tunnel Condensate resistant sheet detail An optional solution applied below the tie beam to prevent the dripping caused by the formation of condensate, in particular environmental conditions

Mobile Tunnels Side opening with safety exit door. A safety exit door can be installed on the long side of the tunnel (depth) Internal lining On request, the tunnel can be insulated with polyurethane insulated sandwich panels

Entrance end closed with RAPIDOOR On request, the tunnel’s end sides can be closed with folding or roll-up high speed doors Side opening with door An opening can be created in the long side of the tunnel (depth), of a size according to customer specifications, to be closed with a RAPIDOOR or SECTIONAL door

HFR Front tunnel detached on four sides or with one end leaning against the building The most widely used solution. The tunnel can have four detached side or the front end leaning against the building. The sides with the pantographs are always closed with sheets down to the ground. The ends are closed with optional curtains or other types of closing devices. The installation requires construction works consisting of continuous foundations for mounting the floor guides. Standard lengths up to 22,000 mm, depth according to customer specifications. Other versions of the HFR model are the fixed...

The HFR Model’s design allows the tunnel to be significantly reduced in length, up to 40%. Basically, a 100 m deep HFR tunnel can be shortened to approximately 40 m. Static dimensional layout L = maximum usable length 22,000 mm HSC = maximum usable height below the tie beam 6,500 mm P = depth according to request S = sliding direction C = compression percentage up to 40% of total depth % = the standard roof slope is 15%

Main “plan view” installation systems Front configuration, detached on four sides with possibility of access from sides 1 and 3 Front configuration with one side leaning against the building. Possibility of access from sides 1 and 3 Front configuration with two sides leaning against the building. Serves as connecting tunnel; may have access from both buildings All solutions may include pedestrian or vehicle openings on sides 2 and 4. Sides 1 and 2 may be closed by a curtain or high speed doors or other closing devices

The tunnel may also be motorized for additional convenience.

Based on the HFR model; structure and size designed for use in goods loading and unloading operations, both in equipped loading docks and on the ground. The solution can be customized according to customer needs.
