The crane girder includes an adapter on at least one of the two opposite ends, which adapter can be fastened to the upper run and the lower run in such a way that the adapter can be oriented relative to the upper run and the lower run and then the adapter can be welded onto the upper run and the lower run in a desired position.

Abstract: The invention relates to a crane, in particular an overhead crane or gantry crane, having at least one crane girder that extends horizontally in a longitudinal direction. The crane is designed as a trussed girder and comprises struts which connect an upper run and a lower run together. The upper run and lower run of the trussed girder are designed in a laminar manner, on which a crane trolley having a lifting gear can be moved. The at least one crane girder is advantageously improved by virtue of the fact that the struts are designed in a laminar manner, each strut has a main surface that extends transversely with respect to the longitudinal direction of the crane girder. The first or second strut end of each strut has at least one aperture on the main surface that lies against the lower run or the upper run.

The crane is designed as trussed girders and each girder includes an upper run with a moveable crane trolley and lifting gear. Each crane girders is composed of two upper run profiles that are connected together via a running rail for the crane trolley. By way of such a design, particularly simple assembly of the crane girders or of the crane can be achieved. Therefore, commercially available, conventional structural steel can be used for the upper run, from which the upper run is produced in a simple manner in terms of manufacturing technology by simple connection to a corresponding running rail.

Abstract: A control method for a balancing lifting gear which includes a lifting motor that can be actuated by a controller and uses a control handle with a force sensor to lift and lower a load-supporting device. In a “Balance” operating mode, the load-supporting device, with or without a picked-up load, is raised or lowered by the controller in response to a force applied by an operator. In order to ensure disturbance-free handling of a load when removing or attaching a load, a “Pick-up” operating mode or an “Assemble” operating mode is selected, in which the load-supporting device is moved independently without the influence of the force of the operator by the controller in the lifting or lowering direction in dependence upon the signals determined by the force sensor. A balancing lifting gear which operates in accordance with the aforementioned control method is also disclosed.

Abstract: A method and control assembly are provided for operating at least two lifting devices, such as cranes, in group and normal operation modes. Each lifting device has a control system connected to a control switch, and the lifting devices are controlled through a common bus. In group operation, the lifting devices are jointly controlled through the bus by one switch. To operate at least two lifting devices in parallel, one of the switches is active in the group operation and the remaining switch or switches are passive. To prepare for group operation, normal operation is deselected by all but one of the control switches to release a remaining switch for log-in to the active state for group operation. To prepare for normal operation, group operation is deselected and normal operation is selected at the active switch before the other switch or switches are released for logging into normal operation.

Abstract: The invention relates to an arrangement comprising a travelling mechanism girder and a running wheel block fastened detachably thereto, wherein the running wheel block is comprised of a housing with at least one connection surface and a running wheel which is mounted in the housing and protrudes out of the housing. To facilitate the exchange of running wheel blocks, alignment of the running wheel block with respect to the travelling mechanism girder is secured through the use of a machined groove, in which a machined plate is held in a form-fitting manner, arranged on the connection surface of the running wheel block. After the running wheel block has been properly aligned, the plate is fixedly connected to the travelling mechanism girder, maintaining the alignment. The invention also relates to a method for the installation of an arrangement consisting of a travelling mechanism girder and a running wheel block.
