Wheel-Blocking Guide Carriage Layout for Rear Beam Clearance

The guide housing is divided into two separate housing parts (first and second housing parts) that can be positioned at different heights. This segmentation allows the system to accommodate both low-positioned truck bodywork and maintain structural stability, resolving the contradiction between stability and adaptability.

The patent introduces a vertical dimension differentiation by positioning housing parts at different heights. The first housing part is positioned at a first height and the second at a second height, creating a multi-level structure that accommodates varying truck configurations while maintaining overall system stability.

The carriage is designed to be movable along the guide, allowing dynamic adjustment of its position. This mobility enables the carriage to adapt to different truck positions and avoid conflicts with rear beams while maintaining proper load distribution through the guide structure.

The separation of carriage and guide as distinct components allows the carriage to move independently along the guide. This segmentation provides the flexibility needed to avoid conflicts with truck rear beams while the guide maintains the load distribution function.

The guide housing is segmented into multiple parts positioned at different heights, creating spaces between them. These spaces allow rainwater to drain through while the carriage maintains efficient movement contact with the guide surfaces.

By positioning housing parts at different vertical heights, the patent creates vertical drainage pathways that allow rainwater to pass through the structure. This dimensional arrangement enables both snug carriage fitting for efficient movement and adequate drainage capability.
