摘要

the structure described here is a refinement of the structure improvement (as described in patent 1039810. the structure is designed so that the effect can be affected by winter conditions, and not have to be a wisselverwarming warms, unlike the in-service switches (crossings.is equipped with two movable tongues not horizontally and vertically adjustable surface at an angle, but that move, and distinction of many structures in the rotation prevention or patented. is equipped with a mechanical seal device.provides construction technical advantages compared to existing structures described in the patent literature and existing in-service switches and crossings. the motion mechanism is designed that forces caused by the weight of the railvoertuig is not transferred to the actuators. is highly desirable during winter conditions.the construction is such that in any situation, and during a single hollow closed spaces contains or late emergence. this water, ice, snow and sand a chance to penetrate the structure and the mechanical force to hinder.
