Cab of small swing radius excavator

Abstract

A cab of a small swing radius excavator is disclosed, which makes it possible to reliably prevent any collisions with a neighboring object in the course of a swing work while achieving a driver's better forward vision, by positioning a handrail in a front left side piller of a cab within a swing radius range of construction equipment, so the handrail can be more conveniently used when a driver enters or leaves a cab. In a cab of a small swing radius excavator which is equipped with a door for opening and closing its entrance, and a handrail installed outside the cab, a cab of construction equipment comprises an improved handrail which includes a lower handrail fixed at a lower outer side of a front left side piller of the cab and positioned within a swing radius range of construction equipment and an upper handrail asymmetrically extended on the lower handrail for being positioned within a swing radius range of construction equipment and fixed at an outer upper side of a front piller.

1 . In a cab of a small swing radius excavator which is equipped with a door for opening and closing its entrance, and a handrail installed outside the cab, a cab of construction equipment, comprising:
 an improved handrail which includes a lower handrail fixed at a lower outer side of a front left side piller of the cab and positioned within a swing radius range of construction equipment and an upper handrail asymmetrically extended on the lower handrail for being positioned within a swing radius range of construction equipment and fixed at an outer upper side of a front piller,   wherein one of said upper handrail and said lower handrail is equipped with a rod shaped straight section, and the other of said upper handrail and said lower handrail is equipped with an arc shaped curved section, and   wherein said upper handrail is fixed while being positioned closer to an entrance of the cab, and the lower handrail is fixed closer to an outer side surface of the front piller while not being positioned in front of a front window, escaping from the front piller of the cab.
