Crane rail for propeller of handling system, has bar provided with narrow rounded areas on both sides for formation of plate chambers, where ratio of head width to breadth of rail base amounts between specific value based on rail height

摘要

The rail (1) has a bar (4) of thickness (D) arranged between a rail head (2) and a rail base (3). The bar is provided with narrow rounded areas (5) on both sides for formation of plate chambers. A ratio of a head width (b) to a breadth (B) of rail base amounts between 0.7 and 1.2 based on a rail height (H). A transition area runs from the bar to the rail base under a radius (R) between 3 and 6 millimeters. A ratio of a head breadth to the bar thickness lies between 1.6 and 2.0 based on the rail height.
