The plates provide a surface with a low coefficient of friction which can be attached to a supporting structure. This combination provides support while simultaneously allowing an object to move (slide) freely along the supporting surface. [1] The plate may be of polytetrafluoroethylene (PTFE),TEF-MET, [2] Lubrite [3] or steel according to the ...
The DRDO Sarvatra (lit. ' Everywhere ') [1] also known as Sarvatra Multi-span Mobile Bridge System is a truck-mounted, multi-span, mobile bridging system developed by Armament and Combat Engineering Systems (ACE) and Research and Development Establishment (R&DE) Engineers of Defence Research and Development Organisation (DRDO) [2] for the Indian army.
Plate girder bridges are suitable for short to medium spans and may support railroads, highways, or other traffic. Plate girders are usually prefabricated and the length limit is frequently set by the mode of transportation used to move the girder from the bridge shop to the bridge site. [3] Anatomy of a plate girder.
BR-90 GSB The BR-90 GSB is the primary general support bridge. It uses the same modular components as the Close Support Bridges. A standard bridge set is carried, launched and recovered from 3 specialist vehicles (1 x Automotive Bridge Launching Equipment (ABLE) and 2 x Bridging Vehicles (BV).
A bridge management system (BMS) is a set of methodologies and procedures for managing information about bridges. Such system is capable of document and process data along the entire life cycle of the structure steps: project design , construction , monitoring, maintenance and end of operation.
Dock levelers (and indeed dock plates and dock boards) are used where a building has a truck-level door, i.e. a door with a floor level roughly at the same height as the floor of the truck's trailer. Some buildings only have drive-in doors, i.e. doors at the same level as the ground outside of the building, suitable for driving directly into ...

The first section of the launch, the launching nose, is not made of concrete, but is a stiffened steel plate girder and is around 60% of the length of a bridge span, and reduces the cantilever moment. [3] The sections of bridge deck slide over sliding bearings, which are concrete blocks covered with stainless steel and reinforced elastomeric pads.
