A device designed for the removal, storage, and installation of convertible hardtops from sport utility vehicles. The device is floor level and mounted on casters for portability. The device utilizes a platform and ratcheted gear apparatus to assist provide leverage and assist a single operator to remove or install a convertible hardtop form an SUV. The device also utilizes a tilting assembly to allow the operator to reduce the footprint of the device with the hardtop loaded, making it simpler to maneuver and store.

A vehicle top lift and storage system is disclosed herein. The vehicle top lift and storage system includes a lift mechanism configured to attach to a vehicle top and to suspend the vehicle top. The left mechanism may include various configurations of straps, hooks, or pulleys, as described herein, to aid in removal of the vehicle top from a vehicle.

The present invention has an objective to provide a dolly for handling a landing gear of an aircraft that enables, while being downsized, work of positioning the landing gear with respect to an attachment portion of an airframe of the aircraft to be performed efficiently, and a method for attaching or detaching a landing gear using the dolly. A dolly (10) for handling a landing gear (20) of an aircraft includes a base (11), an expandable boom (12) that rises from the base (11) and is expandable and contractible, a hoisting boom (13) that is interconnected to the expandable boom (12) in a raisable and lowerable manner, and a holding portion (15) that is suspended on the hoisting boom (13) and retains the landing gear (20).

A control system for a lifting device and a lifting device comprising the same are disclosed. The control system includes a control unit comprising a processor with a memory communicatively coupled to the processor and having computer readable and executable instructions. A battery is electrically coupled to the control unit in addition to at least one indicator. The processor executes the computer readable and executable instructions to: determine an operating characteristic of the lifting device and an operating time of the lifting device as the lifting device is actuated; determine an accumulated load-time parameter for the lifting device based on the operating characteristic and the operating time; store the accumulated load-time parameter in the memory of the lift control system; compare the accumulated load-time parameter to a service constant; and provide an indication the indicator that a lift structural component requires service based on the comparison.

The invention is an apparatus that can handle a bulky and/or heavy object such as construction materials including lifting, transporting, and setting down the object. The apparatus includes a weighed base platform with a mast erected at the front. A cable-based hoisting mechanism is built over the platform such that the cable travels over the top of the mast to the front for securing and hoisting the object. The apparatus includes further stability features.

A portable lifting machine is provided including a rollable base, a base post extending upward from the rollable base, a mast pivotally attached to the base post at a pivot point, and a load lifting assembly attached to the mast and selectively operable to lift a load. The rollable base may include a plurality of legs selectively rotatable about the base between an inward orientation and an outward orientation. The pivoting of the mast on the base post and the rotatability of the plurality of legs on the base can allow the portable lifting machine to move to an orientation where it can be rolled through doorways or other confined spaces.

A method for moving a lifting device includes: in a presetting phase, presetting at least one target position for the lifting device; in a measuring phase, detecting an instantaneous geometry of the arm system; in a selection phase, selecting a target position specified in the presetting phase; in a comparison phase, determining a geometrical deviation between the geometry of the target position selected in the selection phase and the instantaneous geometry detected in the measuring phase; in a generation phase, generating at least one control command on the basis of the geometrical deviation determined in the comparison phase; and in a control phase, performing at least partial movement of the lifting device into the selected target position by actuating the actuators of the arm system with the at least one control command generated in the generation phase.
