A locking device includes a lock body that includes an engagement groove with or from which the closing-side and opening-side lock receivers are engaged or disengaged, the lock body being variable between a neutral posture in which the closing-side and opening-side lock receivers are allowed to be engaged with or disengaged from the engagement groove; a closing-side locking posture in which the closing-side lock receiver that is engaged with the engagement groove is regulated so as not to be disengaged from the engagement groove; or an opening-side locking posture in which the opening-side lock receiver that is engaged with the engagement groove is regulated so as not to be disengaged from the engagement groove; a holding member and a release operation lever.

Cab front window locking device

A cab in a construction machine, the cab including frame members including a hollow first frame member connected to a second frame member in order to form a corner portion, the first frame member including a pass-through portion formed at a first side surface portion of the first frame member; a reinforcing member that is installed at the corner portion, wherein at least one of two sides of the reinforcing member passes through the pass-through portion and abuts against an inner surface of a second side surface portion of the first frame member that is at an opposite side of the first side surface portion; and a reinforcing plate that abuts against an outer surface of the second side surface portion, wherein the at least one of two sides of the reinforcing member is supported and reinforced by the reinforcing plate.

Reinforcement for cab in construction machine

To facilitate the production of a cab in the form of a box by joining side, rear and roof panels to pillars, and to improve the productivity. Pillars forming the cab () include composite pillars () obtained by juxtaposing and joining together the pairs of pillar members (), and panel assemblies () adjacent to the pillar members () are joined to the pillar members () of the composite pillars ().

Cab structure of construction equipment

A vehicle includes a cab; a front window that is capable of moving between a closed position where a window opening at a front surface of the cab is closed and an open position where the front window is housed in a ceiling portion of the cab and the window opening is open; and a guide structure for the front window that guides the front window between the closed position and the open position.

Guide-rail structure of front window in working vehicle

A shutter type guard apparatus composed of a movable guard member which can be opened and closed for covering the window portion of the cab of a piece of machinery. The guard member is structured so that it can be closed to an intermediately opened position where it is easily operated. An auxiliary closing device includes a cable winding device for winding the first cable, a travelling unit coupled between the first cable and a second cable, an auxiliary guide rail in which the travelling unit and the first and second cables are guided for movement, and a pull handle coupled to the second cable. The auxiliary guide member is at one of a pair of left and right guide rails, for guiding the movable guard member. The pull handle is disposed at an intermediate position, in the vertical direction of the guide rail, and by pulling the pull handle downward, the guard member is forcibly closed to an intermediately opened/closed position where it can be easily reached and further closed by hand by an operator.
