Title:
TRAVELLING DEVICES FOR WORKING VEHICLE
Document Type and Number:
Japanese Patent JP2633423
Kind Code:
B2
Abstract:
PURPOSE: To increase the strength of travelling devices by inserting the base parts of mounting frames of right and left travelling devices with the same cross-sectional area as that of the inner hole of a supporting pipe closely into the supporting pipe, and mounting the top end with a cross-sectional area half that of the base parts projectedly from the base parts so that they are overlapped in the supporting pipes in radial direction.
CONSTITUTION: Mounting frames 12 of the same construction are installed on right and left travelling devices SR and SL. The mounting frame 12 is composed of a base part 12a with a cross-sectional area equal roughly to that of the hole of a supporting pipe 13 and a top end part 12b with a cross-sectional area half that of the base part 12a. Then the mounting frames 12 of the right and left travelling devices SR and SL are installed by inserting the base parts 12a closely into the supporting pipes 13, respectively, so that they can move freely in axial direction. In this case, the top end parts 12b and 12b are positioned so that they are overlapped in radial direction of the supporting pipe 13 and set in parallel.
