【発明の名称】走行クレーンのずれを矯正する装置と方法
Document Type and Number:
Japanese Patent JPH0631155
Kind Code:
B2
Abstract:
A skew correction apparatus for a crane traveling on generally parallel spaced apart rails and having a drive wheel on each rail rotatably driven at the same speed. The drive wheels each have center cylindrical portions riding on a rail head and inside and outside flanges facing the sides of the rail head and having a larger diameter than the diameter of the center portion. The clearance distance between the inside flange of each drive wheel and the rail side it faces is smaller than the clearance distance between the outside flange and the rail side the outside flange faces. Thus, if the drive wheels and thereby the crane become skewed, only the inside drive wheel flanges will engage the rail sides. The lagging wheel of the skewed wheels will rotate against the rail side on the larger flange diameter of the wheel and tend to ride up on the rail side. Rotating on the larger flange diameter will increase the linear speed of the lagging wheel, since it continues to rotate at the same rotating speed as the leading wheel, so that it will catch up with the leading wheel and thereby correct the skew.
