摘要： An electric motorization system includes a motorized unit equipped with a motor provided with a rotor and stator assembly including several coils, and a frequency converter which is electrically powered by a power supply. The frequency converter is controlled by a monitoring/control unit for turning on the motor in a variable speed operating mode, or for turning off the motor. The electric motorization also includes a measurement system suitable for measuring at least one condensation parameter which is representative of a condensation of the water contained in an ambient air, and the monitoring/control unit is configured to, depending on said condensation parameter, control the frequency converter during the turning off of the motor so that a preheating electric current flows through the coils to activate a preheating of the motor when it is turned off.

摘要： A clamp assembly comprising a pair of clamps may couple to an assembly body. The clamps may pivot to receive material beneath the assembly body. The clamps may include opposing surfaces that define a scoop space beneath the assembly body. Each of the clamps may include a cutting plate. The cutting plate may include a perforating edge configured to extend into the scoop space relative to a corresponding one of the opposing surfaces. The clamp may further include a retention plate. The retention plate may include an inner surface that faces the cutting plate. The cutting plate and the retention plate further define the scoop space between the clamps. The clamp assembly may couple to a lift assembly. The lift assembly may include a hydraulic actuator configured to raise and lower the clamp assembly.

摘要： The invention relates to a brake assembly (1) for securing a conveyor device, in particular a crane system (100), comprising a first brake device (7) which acts on a first drive element (3), a second brake device (8) which acts on a second drive element (5), a transmission device (4), in particular a gearbox, acting between the first and second drive element, a load sensor (13, 13′) which detects a load signal and passes same on to a controller (9), and the controller (9) is designed in such a way that, based on a load signal that exceeds an overload threshold, it initiates an emergency brake status and actuates the first and the second brake device (7, 8) in such a way that they act on the first and second drive element (3, 5) simultaneously within a first brake acting time, wherein one of the first and second brake devices is designed such that it acts on the first and/or the second drive element within a second brake acting time in a normal brake status, and the first brake acting time is shorter than the second brake acting time.

摘要： The present disclosure presents systems and methods for assisting a crane operator. An imaging system automatically images each building material object contained within a shakeout field on a construction site and processes the images to determine each object's identifying indicium and its geometric properties. These values are compared with a construction site database to ensure that all necessary building materials are present. A positioning device tracks, in real time, the location of the imaging system, the location of structural members within the shakeout field, and/or other important features of the job site, such as obstacles that the crane operator will need to avoid while lifting a structural member from its initial location to its destination location. Real-time images of the construction site, including indications of the next building material object to be hoisted and/or a path between the object's initial and final locations, can be generated to guarantee that the crane operator hoists the expected object to the expected location.

摘要： A rope hoist, which comprises a rope drum for a hoisting rope to be winded thereon and a rope drum cover for partially surrounding the rope drum. Visually observable or readable means for detecting winding/unwinding positions of the hoisting rope on the rope drum are arranged on the rope drum cover, and to indicate lifting height of a load attached to the hoisting rope.

摘要： For optimizing an anti-sway algorithm for the transport of a load by a hoisting appliance spanning a hoisting area and comprising a trolley, a reeving system and a tool handling the load, a control device is able to:
create a first table giving angle offsets of the trolley, depending on physical characteristics of the load and on mechanical parameters related to the trolley, the angle offsets being determined by measurements of inclination angles of the trolley,
create a second table giving probabilities of a secondary sway of the load depending on physical characteristics of the load, on mechanical parameters related to the reeving system and on measurements of acceleration and angular position of the tool, and
transport the load in the hoisting area by using an anti-sway algorithm taking into account the first table and the second table, wherein anti-sway algorithm takes as inputs dynamic parameters of hoisting appliance comprising the current position of the trolley, the load and the current angle of the load with respect to the trolley.-

摘要： A zero-gravity hoist system including a chain fall, a motor coupled to the chain fall and configured to drive the chain fall in one or more directions, a power supply configured to provide power to the motor, and a controller having one or more electronic processors. The one or more electronic processors are configured to measure a first force of a load in response to receiving an input, store the measured first force in a memory of the controller, measure a second force of the load, determine a difference between the second measured force and the first measured force, and adjust a height of the load based on determining that the second force differs from the first force by a predetermined threshold.
