Abstract

PROBLEM TO BE SOLVED: To easily load an aboveground cargo, and prevent falling of the cargo by integrally forming on a mast a guide groove for lifting a loading space in a forward/upward attitude and a forward/downward guide groove for changing the loading space in a forward/downward attitude in the most lowered position of the loading space. SOLUTION: The lower end of a mast 2 and a forward/downward guide body 30 are fastened/fixed to a carriage frame by a bolt 24, and a forward/ downward guide groove 31 having the lower end side formed of an inclined face inclined backward is arranged in a forward/downward guide body 30. The upper end of the forward/ downward guide groove 31 is connected to the lower end of a guide groove 12 of the mast 2, and when a loading space 1 is lowered most, a guide roller 11 is moved to the forward/downward guide groove 31 so that the loading space is supported forward/downward by a specific angle in the most lowered position. The loading space 1 is constituted so as to be supported forward/upward by a specific angle by moving the lower guide roller 11 to the guide groove 12 by raising the loading space 1. Thus, cargo loading/unloading workability is improved, a cargo is stably supported, and falling of the cargo can be prevented.
