Work vehicle

Abstract

Provided is a work vehicle in which a positioning antenna can be installed above a roof plate of a cab at an accurate position and in a proper attitude while preventing a positioning accuracy from being decreased by vibrations. The work vehicle includes a first mount member, a second mount member and a positioning antenna. The first mount member includes a left-side member fixed on the roof beam at the left side and a right-side member fixed on the roof beam at the right side. The second mount member is disposed above the roof plate across the left-side member and the right-side member. The positioning antenna is mounted on the second mount member.

1 . A work vehicle comprising:
 a work implement;   a cab to be boarded with an operator to operate said work implement,   said cab including a lateral pair of roof beams disposed respectively on the top of both side surfaces of said cab and a roof plate supported respectively by said pair of roof beams;   a first mount member including a left-side member fixed on said roof beam at the left side and a right-side member fixed on said roof beam at the right side;   a second mount member disposed above said roof plate across said left-side member and said right-side member; and   a positioning antenna mounted on said second mount member.   
     
     
         2 . The work vehicle according to  claim 1 , wherein said roof plate is convexly curved upward. 
     
     
         3 . The work vehicle according to  claim 1 , wherein a gap is formed between said second mount member and said roof plate. 
     
     
         4 . The work vehicle according to  claim 3 , further comprising an antenna cable connected to said positioning antenna, wherein a part of said antenna cable is disposed inside said gap. 
     
     
         5 . The work vehicle according to  claim 1 , wherein said left-side member and said right-side member are welded on upper surfaces of said roof beams. 
     
     
         6 . The work vehicle according to  claim 1 , wherein
 said cab further includes a width-direction roof beam disposed on the top of said cab and extending in the width direction of said work vehicle,   said first mount member further includes a width-direction member fixed on said width-direction roof beam, and   said second member is supported by said width-direction member.   
     
     
         7 . The work vehicle according to  claim 1 , wherein
 said second mount member has an antenna installation surface, and said positioning antenna is mounted on said antenna installation surface, and   said antenna installation surface has a planar shape.
