Big Door 1 - Hi Res

BIGDoor© automated entry systems are custom designed and have many advantages over other door types such as sliding or rolling doors.

There are no ground tracks needed, and the entry system can be custom designed to suit the size of the openings or the style of the buildings.

The entry system construction is of aluminium and steel profiles providing it with the optimum combination of stability and weight. A high tensile PVC shell covers both sides.

The control system consists of a fully integrated PLC control system which can be fully integrated with a Building Management System (BMS).

Operations of the BIGDoor© automated entry system are controlled by a programmable login security system. Full program diagnostics and data login capabilities are available.

BIGDoor© automated entry systems are structurally certified to AS/NZS 1170.2:2011 Structural Design Actions – Wind Actions to suit Australian conditions.

These highly specialised entry systems are specifically designed to be installed in very large buildings: for mining; industrial; aviation (including airline hangars); the energy sector; shipbuilding, marine and ports; and maintenance facilities and mega warehouses generally.

iPilot Australia has established itself as an important and emerging supplier of these "BIG" scale entry systems - with design and build technologies that put it among the world leaders in these products and services categories.

BIGDoor Design

The door’s construction is made from aluminium and steel profiles. These materials provide the door with the optimum combination of stability and weight. A high tensile PVC Shell covers both sides of the door.

Bottom Truss

Hoisting Mechanism (Sheaves, Winch and Wire Rope)

The sheaves are located at the ends of the top truss. The winch is located in the middle of the top truss. Wire ropes are wound around the winch drums, through the sheaves, and attached to the bottom truss.

Bottom Truss

The bottom frame of the door is a welded steel truss. The truss is capable of supporting the weight of all the cross members when the door is in its fully opened position.

A rubber seal is attached onto the bottom of the truss to ensure that dust is contained inside the building.

Cross Members

Cross members are made from high grade aluminum alloy for its lightweight, stiffness and strength.

Roller bearings are attached onto the ends of each cross member to ensure that they are in contact with the guide rails and are able to move freely. Wind load on the door shall be transferred to the guide rails via the cross members.

Guide Rails

Steel guide rails are fixed onto the building columns. The guide rails guide the vertical movement of the roller bearings on the bottom frame and cross members.

High Tensile PVC Shell

The PVC fabric covers both sides of the door and is secured to the aluminum cross members by aluminum fixing straps.

The PVC fabric has the following properties:

  • Corrosion resistance
  • Flame resistance – self extinguishing
  • Lightweight
  • Resistance to mould, rotting and UV rays

Control System

The control system consists of a fully integrated PLC control system which can be fully integrated with a Building Management System (BMS).

Operations of the door are controlled by a programmable login security system.

Full program diagnostics and data login capabilities are available.
