Abstract: The invention relates to a system for creating a sealable tank partition from wooden panels (1). Said system includes a rigid structure that consists of: a lower girdle (2) and an upper girdle (3) which are formed by profile elements (21) assembled with each other. Posts (4a, 4b) are placed between said upper and lower girdles (2, 3). This rigid connection is provided by a device consisting of: a post (4a, 4b), having two ends, at least one tenon (62a, 62b) being located at each of the ends; at least one profile (21), having two ends (23), at least one mortise (61a, 61b) being located at each of said ends (23), the mortises (61a, 61b) of two adjacent profiles (21) being stacked on top of one another, and the tenons (62a, 62b) being inserted into the stacked mortises (61a, 61b).

Abstract: The invention concerns an arrangement for the securing of an implement to a lifting arm, particularly to a front loader, where the implement and the lifting arm can be fastened to each other by a movable locking bar, which can be moved between a locking position and an unlocking position, and can be brought from the locking position into the unlocking position by a remotely actuated hydraulic cylinder. It is proposed that the locking bar can be arrested automatically in the unlocking position, with it then being possible for the hydraulic cylinder to be deactivated. The locking bar is located such that it can be brought into the locking position from its arrested position by moving the implement by another remotely actuated hydraulic cylinder such that the locking bar engages the lifting arm and is moved to a non-arrested position from where it is automatically biased back into its locking position.

Abstract: The invention pertains to a device for attaching an implement to a lifting unit, in particular, to a front-end loader, wherein the implement and the lifting unit can be connected to one another by a movable bar that can be displaced from a locking position into an unlocking position by an externally activated actuator. The actuator is coupled to the bar by a coupling device designed such that a driving connection between the actuator and the bar is only produced when the actuator is activated. This makes it possible to displace the bar manually, as well as in an actuator-operated fashion.

Abstract: A tractor-mounted front end loader includes lift boom having a tool, disclosed as a bucket, pivotally mounted to one end of the boom for selected movement by one or more hydraulic adjustment cylinders. A safety valve is associated with one of the pressure chambers of each adjustment cylinder to prevent unintended lowering of the tool in the event a supply-return hose extending between a direction control valve and the adjustment cylinder should rupture. Also connected to this pressure chamber of each adjustment cylinder is an accumulator for providing a damping action. The connection between the pressure chamber and the accumulator is made by rigid tubing, and in one disclosed embodiment, includes a remotely operable on/off valve for selectively coupling the accumulator to the pressure chamber.

Abstract: A hydraulic control arrangement for a mobile work machine includes at least one hydraulic cylinder by means of which an operating tool can be moved. A direction control valve is provided for controlling the path of pressurized fluid between a pressure chamber of the cylinder, a pump, and a tank, as well as a safety valve inserted between the directional control valve and the pressure chamber of the cylinder to which pressure is applied during the lifting of the operating tool. The safety valve opens automatically when presssure is applied to the cylinder and is closed when no pressure is applied to the cylinder. The safety valve further operates so that it opens, automatically and independently of the pressure in the pressure chamber, during the lowering of the operating tool and/or during a float operating mode, selected by an operator.
