Abstract
A ROPS frame for a work vehicle includes: a first pipe having an end; a second pipe having an end facing the end of the first pipe; a plate-shaped first joint coupled to the end of the first pipe and oriented orthogonally to a longitudinal direction of the pipes; a plate-shaped second joint coupled to the end of the second pipe and oriented orthogonally to the longitudinal direction of the pipes, the second joint being placed on the first joint; and a bolt extending through the first and second joints and fastening the first and second joints to each other.
Claims8
A roll-over protective structure (ROPS) frame for a work vehicle, comprising:
- a plurality of pipes comprising:
- a first pipe having a rear end;
- and
- a second pipe having a front end facing the rear end of the first pipe, the rear end and the front end being disposed in an upper portion of the ROPS frame;
- a plate-shaped first joint coupled to the rear end of the first pipe and oriented orthogonally to a longitudinal direction of the pipes;
- a plate-shaped second joint coupled to the front end of the second pipe and oriented orthogonally to the longitudinal direction of the pipes, the second joint placed on the first joint;
- and
- a pair of bolts each extending through the first and second joints and fastening the first and second joints to each other,
- the first pipe and the second pipe each have a pair of recesses which are recessed toward an axial area of the pipe, the pair of recesses arranged opposite to each other across the axial area, as viewed in the longitudinal direction,
- the pair of recesses includes a first recess positioned upward relative to the axial area and laterally inward relative to the axial area, and a second recess positioned downward relative to the axial area and laterally outward relative to the axial area, and
- the pair of bolts includes a first bolt adjacent to the first recess, and a second bolt adjacent to the second recess.
