摘要: A crane risk logic apparatus and system and method for use of the same are disclosed. In one embodiment of the crane risk logic apparatus, the crane risk logic apparatus is integral with a crane, such as a crawler crane or a tower crane, and located in communication with a load moment indicator. The crane risk logic apparatus receives crane data from the load moment indicator and determines lift cycle data therefrom. The crane risk logic apparatus determines an area of interest based on locationing data received from a global positioning system (GPS) unit incorporated therewith and receives weather data for this area of interest. The crane risk logic apparatus causes an alert notification at the crane to occur in response to presence of weather issues.

摘要: The invention relates to a crane, in particular a rotary tower crane, comprising a lifting cable configured to run out from a crane boom and comprises a load receiving component, drive devices configured to move multiple crane elements and displace the load receiving component, a controller configured to control the drive devices such that the load receiving apparatus is displaced along a movement path, and a pendulum damping device configured to dampen pendulum movements of the load receiving apparatus and/or of the lifting cable. The pendulum damping device comprises a pendulum sensor system configured to detect pendulum movements of at least one of the lifting cable and the load receiving component and a regulator module comprising a closed control loop configured to influence the actuation of the drive devices depending on a pendulum sensor system signal returned to the control loop.

摘要: A limited rotation slewing ring crane may include a pedestal, a column rotatively coupled, about a first rotation axis, to the pedestal by a slewing ring rotative coupling, and stops for limiting the relative rotation of the column with respect to the pedestal. The crane may also include a rotative sensor adapted to measure a rotation angle of the column with respect to the pedestal. The rotation sensor may include a tubular body axially extending from the base of the column, a stationary body connected to the pedestal and a wheel. A second rotation axis of the wheel may be offset with respect to a first rotation axis of the column with respect to the pedestal.

摘要: This defining method comprises the steps of: —simulating a crane comprising: i) a boom made up of elements and ii) a lifting member that is able to move along the boom, —selecting several elements to be tested, maximum stresses, and several ranges along the boom, and —carrying out the following analysis steps of: •choosing a theoretical load, •calculating stresses brought about by the theoretical load in each element to be tested, •comparing these stresses with maximum stresses, •increasing or decreasing the theoretical load depending on whether stresses are less than or greater than the maximum stresses, •repeating the calculating step and the comparison step and the step of increasing or decreasing until the maximum theoretical load is found, and •recording i) the range and ii) the maximum theoretical load.

摘要: The invention relates to a hoist mechanism (20) intended primarily, but not exclusively, for moving a motor driven wheelchair or scooter into and/or out of the load carrying space of a vehicle. The hoist mechanism (20) comprises a lifting arm having, at least in part, a generally U-shaped cross section, and an actuator (28). A mounting point (56) for the actuator (28) is provided within the generally U-shaped cross section. The invention also relates to a stepless adjustment system suitable for use in such a hoist mechanism (20). The adjustment system comprises an inner section (34) received within an outer section (24) in a telescoping arrangement. The outer section (24) comprises first and second body portions (44A, 44B) provided with features for engaging corresponding features (48A, 48B) provided on the inner section (34).

摘要: The present invention relates to a crane, in particular in the form of a revolving tower crane, having a jib (3) and a counter-jib (4), which are articulated on a jib articulation piece (8), wherein the jib (3) comprises an outer jib part (3a), which is articulated on an inner jib part (3i) in a hinged manner and is held by a guy (10). According to the invention, the inner jib part (3i) is in the form of a cantilever, which is fastened to the jib articulation piece (8) in a flexurally rigid manner and held, wherein the outer jib part (3a) is articulated on the cantilever in a hinged manner and is held by the guy (10).

摘要: A tower crane includes a tower on which is pivotally mounted a boom displaceable between a lowered position and a raised position. The crane is configurable between a service configuration in which the boom is controlled in rotation and a weather vane configuration in which the boom is in the raised position and is released in rotation on the tower to allow orientation in the direction of the wind. A wind load system is mounted on the boom and is adjustable between a retracted shape in the service configuration providing a reduced surface exposed to the wind, and a deployed shape in the weather vane configuration providing an extended surface exposed to the wind. The wind load system is configured to move from the retracted shape to the deployed shape under the effect of its own weight alone (i.e., under gravity) when the boom is raised.
