摘要： Disclosed are various embodiments for stabilizing a hoisted object. A hoisted object such as a litter can have a tendency spin while being retrieved on a lift line. A device may be connected to the hoisted object to reduce a spin or other angular velocity of the hoisted object. The device may monitor stability of the hoisted object and determine that the hoisted object is unstable. The device may be configured to rotate at least one flywheel to apply torque to an enclosure of the device.

摘要： A crane hook rotation-limiting device includes a mounting base and a plunger extending through a hole formed in the mounting base so as to be movable with respect to the mounting base. A spring first bearing portion is connected to the plunger so as to be movable with the plunger. A spring second bearing portion is positioned opposite the spring first bearing portion so as to be fixed with respect to the plunger during movement of the plunger. A spring member extends between the spring first bearing portion and the spring second bearing portion. A pair of crane hook rotation-limiting devices as described herein may be mounted to a crane hook assembly to control rotation of the crane hook during movement of the hook when the hook supports a sling spreader or a sling spreader and a die (or other item of tooling).

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 hydraulic system (600) and method for reducing boom dynamics of a boom (30), while providing counter-balance valve protection, includes a hydraulic cylinder (110), first and second counter-balance valves (300, 400), and first and second control valves (700, 800). A net load (90) is supported by a first chamber (116, 118) of the hydraulic cylinder, and a second chamber (118, 116) of the hydraulic cylinder may receive fluctuating hydraulic fluid flow from the second control valve to produce a vibratory response (950) that counters environmental vibrations (960) on the boom. The first control valve may apply a holding pressure and thereby hold the first counter-balance valve closed and the second counter-balance valve open.

摘要： Disclosed are systems, apparatuses, and methods to deploy and stow a deployable equipment to and from a hoist, to control a load on a suspension without transfer of torque to the suspension cable, for the deployable equipment to obtain data and electrical services from a dock of a carrier, and for the deployable equipment to control the hoist, such as a reel of a hoist, to control a z-axis of a terminal end of the suspension cable. Control of the z-axis may be, for example, to control an elevation of a load, such as relative to carrier, ground, or an objective or target, to control a tension on or of suspension cable. Control of the z-axis may be, for example, to control a rate of ascent or descent of a terminal end of suspension cable.

摘要： Heave balance device (1) can balance a lifted or supported load (8). The load can be lifted by a hoisting device (10) or it can be supported. The heave balance device comprises a first frame (2) and a connection unit (22) that can be suspended, e.g. to a hoisting device. Further a moveable carrying unit (32) allows for carrying (suspending or supporting) a load. The device comprises a transmission that couples the connection unit and carrying unit, wherein said transmission is arranged to guide the connection unit and the carrying unit to move along a guideline with respect to each other, the transmission having a spring force balancing arrangement (4) with one or more leverage units, such as one or more pivoting arms (50, 51), and with one or more configurable (gas- or) hydropneumatic springs. A method comprises suspending the load via a (heave) balance device. Further a kit of parts for hoisting devices is provided to allow load decoupling.
