The traditional building system with rims reinforced by angle profiles and strong head and pit base profiles, on which the dock leveller is to be welded, is still used. The pit may be simple, elongated at ground level or have lower clearance for tail lifts: the dock leveller has no influence on the depth of the pit. Poor dimensions and squaring often cause expensive redundant re-makes before being able to install the dock leveller. The bumpers are directly installed on the concrete, at side of the pit.
simple traditional pit
the three perimetrical armoured walls of the pit are built, with bracketed angle profiles cast into the rims and strengthened head and base of pit profiles.
similar to the above construction, with a pit of the same height as the dock, that allows for a step on the internal side of the pit and a profile on the external one, on which the dock leveller is put. The three perimetrical armoured walls of the pit are built, on the rims of which are cast bracketed angle profiles,and stronger head and base of pit profiles. The dock leveller lays on a reinforced step on the inside wall and a front profile.
