A sliding-gate installation (100) serves to close a gate opening (1). Fitted at the two ends of the gate (10) are supporting wheels (20) which are suitable for running on the road and do not require a running rail which is provided as a foundation in the ground. In order to compensate for the inaccuracies, which occur as a result of this free displaceability of the gate (10), in the positioning at the posts (2, 3), the invention provides guidance devices (30, 31) which open in the form of a funnel towards the oncoming supporting wheel (20) and move said supporting wheel (20) into the correct position. <IMAGE> |
