A mobile gantry is said to be externally braced when the runway is given rigidity by a diagonal bracing member positioned from the support to the runway on the outside of the goalpost arrangement.
A mobile gantry is a free standing structure compromising a runway beam and two supports assembled in a goalpost-like configuration, The supports are usually mounted on wheels or castors to enable the structure to be relocated by man power only; they may however be mounted on free standing feet requiring the structure to be dismantled for transportation.
Bracing is used to give support, rigidity and longitudinal stability to the runway. There are four common methods of bracing
A mobile gantry is said to be externally braced when the runway is given rigidity by a diagonal bracing member positioned from the support to the runway on the outside of the goalpost arrangement.
A mobile gantry is said to be internally braced when the runway is given rigidity by a diagonal bracing member from the support to the runway on the inside of the goalpost structure.
A mobile gantry is said to be box braced when the runway is given rigidity by the box-like design of the supports.
A mobile gantry is said to be rigid or splice braced when the runway is given rigidity by the design of the joint or splice between the supporting member and the runway .
The height of a mobile gantry is normally measured from the floor to the under side of the runway beam. The overall height is measured from the floor to the top of the highest point of the structure.
The span of a mobile gantry is normally measured between the wheel centres along the line of the runway (longitudinally).
The clear span is the clear distance between any internal structural members and represents the maximum width of any item over which the gantry may be positioned or passed.
The effective length of a gantry is the distance the lifting appliance and trolley may travel along the runway between the end (travel) stops.
Overall length is the distance between the extremities of the structure measured along the line of the runway (longitudinally) and represents the minimum width which the gantry may pass when an allowance is added for clearance.
The width of a gantry is measured across the bases member of the support.
