BridgeXpress^© parapet track

BridgeXpress^© is the principle of a monorail parapet track based on the concept of suspended scaffolding and falsework that can be moved and that complies with DIN EN 12811.

Application

The individual track (BX-MonoRail) is secured underneath the decking with the help of moving roller bearings. Depending on the bridge geometry, specific number of gondolas is mounted on the rail; these gondolas are then coupled with each other. This means that BridgeXpress^© possesses a modular design and may be easily and rapidly moved with the help of BX Flexi-Rolls. Using the attached hydraulic cylinders (BX Hydro-Lift technology), the formwork is moved quickly to the concreting position and may be removed once the concrete has set.

Benefits

• Rapid cycle times
• Safe handling
• Universal application
• Unachieved versatility
• Cost reduction

The four-phase process: Creating parapets with BridgeXpress^©

Phase 1: Positioning

• Securing BridgeXpress^©
• Extending the hydraulic cylinders and raising the structure
• Anchoring with  threaded rods
• Relieving the weight on the hydraulic cylinders

Phase 2: Concreting

• Relieving the weight on the stabilising wheels by folding out the pressure props
• Preparing for concreting
  (Creating the formwork, reinforcement, built-in parts)
• Concreting

Phase 3: Striking the formwork

• Hydraulic lowering of the structure
• Removal of the anchors (B15)
• Folding away and releasing the pressure props

Phase 4: Moving

• Moving the BridgeXpress^© into the new concreting position, e.g. with cable and gripping hoist

Mounting trolley, front carriage

• Installing the fastening elements to the defined BX anchors (Kobold® B15)
• Rail installation

Mounting trolley, rear carriage

• Removal of the rail and its fastening elements
• Proper closing of the anchoring openings
