Abstract (en)
[origin: EP0163180A2] A lifting gate (1) is described which can be completely sunk in to a ground opening (4). The lifting gate (1) is accommodated in a container whose base wall (5) and side walls (6,7,8,9) serve as formwork when the container has been inserted in the ground opening (4). The top wall (3) of the container is at the same level as the ground (2) and has a slotted opening (10) which opens the way for the upward or downward travel of the lifting gate (1). A cylinder/piston means (13), which is subjected to the pressure means from a drive unit (14), acts on the lifting gate (1). The lifting gate (1) is guided on both sides on fixed vertical guide rails (18) which are preferably formed from two corner posts of the container frame and extend only to the group (2) or to the top wall (3), i.e. do not project beyond the latter. <IMAGE>
