C" SUSPENDED dock leveller, pre-mounted on a frame leveller to be welded to the rods cast into the cement all around the pit rim. The pit can have the bottom reservation for tail lift, like the shown case (picture A), that requires the heavy reinforcements for sustaining the overhangs.
There is a risk of fractures into the pavement all around the pit, because of the different dilatation of the parts.
The "C" SUSPENDED dock leveller is to be installed before the pavement casting, with all risks of dirtying it with aggressive.
With the "C" frame the construction comes in four times: building as per drawing, leveller installation and levelling, welding of the leveller, final pavement laying. In the picture A, the inside, before pavement is laid.
"L" SUSPENDED dock leveller. It has an upside-down "L" frame (picture B) that requires a special counter-frame anchored into the pit-rim-construction, as per drawing, onto which the "L" is laid and fixed by welding that remain at sight with doubtful aesthetic. This system had been designed for avoiding the fractures into the pavement that often occur with the "C" Suspended levellers.
With the "L" Suspended leveller the construction comes in three times: building as per drawing with special frame fixed into the pit-rim, final pavement laying, leveller installation with welding.
The "L" SUSPENDED frame is to be installed at the end of all wet-trades, by welding (that remain at sight) to the counter-frame.
The bumpers shall be installed separately, on the building walls at the outside sides of the leveller pit.
