3.6 maximum crossing width

maximum horizontal distance (L1) from the outermost edge of the working side of the vehicle to the inner side of the vertical boom when the bridge inspection vehicle is working, as shown in Table A.1 of Annex A

3.7 maximum crossing height

maximum vertical distance (H1) from the highest point on the lower side of the main boom to the bearing surface when the bridge inspection vehicle is operating, as shown in Table A.3 of Annex A

3.8 maximum working height

maximum vertical distance (H2) from the bearing surface of the work platform to the bearing surface of the bridge inspection vehicle when the work platform is above the bearing surface of the bridge inspection vehicle, as shown in Table A.4 of Annex A

3.9 slewing center I

overall slewing center of the bridge inspection equipment

3.10 slewing center II

slewing center of the work platform

3.11 rated load

normal operating load designed for the work platform, consisting of loads of the workers and working equipment acting vertically on the work platform

Note: a work platform can have multiple rated loads.
