A method and apparatus for transporting loads includes a gripper pliers including a pair of pivotable gripper arms, each of which has a gripper claw. A positioning element is operatively coupled to the pair of gripper arms for pivoting the gripper arms in a pivoting plane and displacing the gripper arms in a gripping direction transversely of the pivoting plane into a position so that the gripper claws can engage connecting regions of the load. At least one of the gripper arms includes a transverse guide for fixing it against further pivoting and back-pivoting within the pivoting plane after the gripper arm has pivoted into an operating position for being displaced in the gripping direction.

The invention relates to a transloading apparatus for transcontainers such as freight containers, interchangeable containers and semi-trailers including a crane trolley adapted to travel on a crane or portal, to which, by way of a lifting means, a load receiving means is fitted in a manner for raising and lowering. In order to enable the load receiving means to be guided and aligned more accurately in relation to the transcontainer, provision is made to connect to the load receiving apparatus two horizontally movable columns or lifting structures at a distance from one another which is fixed or can be adjusted in a defined manner and to reader these vertically displaceable. Preferably each of the columns or each of the two lifting structures can be connected by way of a pendulum suspension to the load receiving means.

摘要:
A lifting and transport apparatus for containers has a fixed rigid horizontal beam on the lower flange of which two wheeled carriages are displaceable either together or separately to allow, in the latter case, a change in the distance between the carriages and, in the former case, displacement of the container. A cross beam on each of the carriages can carry at its ends fixed columns which guide respective lifting elements having claws at their ends engageable with the container. The entire assembly is free from cables or the like which can introduce sway.

The present invention relates to a device for generatively manufacturing a three-dimensional object (3), comprising: a frame (1) defining a building field (6) at an upper portion (2) thereof; a plate (12) which connects the frame (1) with a housing (100) of the device; a support (5) which is arranged in the frame (1) and vertically movable by a lift mechanics (4) at least below the building field (6); a radiation device (7) which generates an energetic beam (8, 8′) which is focused by a deflection means (9) to arbitrary points in the building field (6), so as to selectively sinter or melt a powdery material (11) which is present in the building field (6); a coater (10) for applying a layer of powdery material (11) onto the support (5) or a previously applied layer of the powdery material (11). A thermal insulation (13) is arranged between the frame (1) and the plate.

Method and apparatus for detecting tank leaks, in which a gas pressure acts on a fluid which is situated in a tank, and in which the gas pressure in the tank or tank system is changed, wherein a tank leak is detected by evaluation of a temporal profile of a sum pressure of the fluid which is situated in the tank.
摘要:
A procedure to diagnose a fuel tank ventilation system of a motor vehicle and a device to implement the procedure are proposed. The fuel tank ventilation system contains at least one first ventilation pathway discharging into the air intake area of the internal combustion engine downstream behind a supercharger as well as at least one second ventilation pathway discharging into the air intake area upstream in front of the supercharger. Provision is made for a diagnosis with at least two partial diagnoses, whereby the first partial diagnosis pertaining to the first ventilation pathway is implemented, if the intake manifold pressure in the discharge area of the first ventilation pathway is smaller than the fuel tank system pressure; and the second partial diagnosis pertaining to the second ventilation pathway is implemented, if the intake manifold pressure in the discharge area of the first ventilation pathway is greater than the fuel tank system pressure. An error signal is provided, if at least one of the partial diagnoses generates a partial error signal.
摘要:
An internal combustion engine includes multiple combustion chambers. The supply of fuel into at least one subset of the combustion chambers can temporarily be interrupted. It is provided that the fuel be injected into the combustion chambers directly and during a switchover phase for interrupting or resuming fuel injection into the subset of combustion chambers, at least temporarily via multiple injections.
摘要:
In a method for determining the rotational speed of the crankshaft of an internal combustion engine having a sensor disk which is connected to a crankshaft of the internal combustion engine, the sensor disk having a marking via a system of alternating teeth and tooth spaces, and a first sensor assigned to the sensor disk generating an electrical signal which is able to assume at least two signal levels, one of the signal levels being assigned to a tooth and the other being assigned to a tooth space, the accuracy of the rotational speed determination is increased in that the rotational speed of the crankshaft is determined by the control unit from the angle between two markings divided by the time elapsed between the two markings; additional markings may be situated between the two markings and the number of markings which are situated between the two markings is a function of the rotational speed.
