OPERATION STAND DEVICE FOR CONSTRUCTION MACHINE

PURPOSE:To improve operability by reducing a sense of incompatibility given to an operator when a height of an operation lever is changed in an operation stand device for a construction machine. CONSTITUTION:An operation stand device has a support mechanism 7 to support the rear end of a console 2 rotatably to a floor surface 6 and a support mechanism 8 to support the front end of the console 2 so as to be adjustable in the height direction. The support mechanism 8 has a support member 8a, an installing member 11 and a height adjusting plate 12 to connect these to each other, and the height adjusting plate 12 is fixed to the installing member 11, and three bolt holes 13 are bored therein, and it is fixed to the support member 8a when a bolt 14 is inserted in one of them. Since the rotational center 9 of the support mechanism 7 is situated in the rearward of a seating position, an angle of an operation lever 4 and a change in a longitudinal moving distance when a height is changed are small. Since the whole console moves vertically according to the operation lever 4, a position of the console to an operator is changed, so that operability is not spoiled.
