A stock supply assembly for a dunnage conversion machine includes a stock material support having a support structure, such as a shelf for a stack of fan-folded sheet stock material. The shelf is movable between a relatively lower loading position and a relatively higher operating position vertically displaced relative to the loading position. In the process, the support structure maintains a consistent orientation as the support structure moves between the loading position and the operating position.

A lifting apparatus, including a support carriage movable along a track, a lifting element for holding a load, a lifting device for raising and lowering the lifting element vertically relative to the support carriage. The lifting device includes at least two tension elements, wherein each tension element can be wound onto the supporting carriage by a winding apparatus. A first drive is provided for driving a first winding apparatus and a second drive is provided for driving a second winding apparatus. The first drive has a drive motor which drives a shaft by a conical gear mechanism, the shaft drives a roller of the first winding apparatus by a gear mechanism element and the second drive has a drive motor which drives a roller of the second winding apparatus by a spur gear, parallel-shaft gear or planetary gear mechanism.

A hoisting device includes a first part movably connected to a running rail above it, and a second part suspended under the first part, and a hoist arranged between the first part and second part to lift and lower the second part. In addition, a scissors mechanism is arranged between the first part and second part to prevent the horizontal movement and twisting movement of the second part in relation to the first part. Such a hoisting device is advantageous, because the second part of the hoisting device may be lifted and lowered at the same time as the first part is moved without any notable swinging exerted on the second part.

A drop table can provide optimized lifting operations by employing motor feedback to generate and adapt a lifting strategy that controls lifting parameters. A lifting module may be connected to a first motor and consist of a lifting controller. The first motor can be mechanically coupled to a first lifting column by a first transmission and to a second lifting column by a second transmission. A service component can be lowered with the first and second lifting columns by activating the first motor that provides motor feedback. A lifting strategy can be generated in response to the motor feedback and subsequently executed to move the service component to a servicing position.

An inverted carrier lift and method is disclosed. The inverted carrier lift includes a trolley movable along an overhead conveyor and a carrier for supporting a workpiece to undergo an assembly or manufacturing process. The carrier is movable relative to the trolley from a raised position to a lowered position by a motor engaged with a lifting mechanism on the trolley. On rotation of the motor, the carrier and supported workpiece is lowered or raised to position the workpiece in the workstation for processing. The workpiece may be disengaged by the carrier for support of the workpiece by one of many different fixtures depending on the processing. Following processing, the workpiece is re-engaged by the carrier, moved to a raised position and the trolley is transferred to a subsequent workstation.

The invention relates to a handling apparatus (1), having a drive carriage (2), which is movable relative to a carrier (3), wherein a scissor lift (7) having a plurality of scissor lift members (8) is arranged on the first end of the drive carriage (2), wherein a carrier plate (11), which is movable by means of the scissor lift (7) relative to the drive carriage (2), is arranged on the second end of the scissor lift (7), wherein a gripping tool is arranged on the carrier plate (11), wherein the gripping tool has at least two guide rods (13) mounted on the carrier plate (11), wherein a gripping element (14) is arranged on the end region of each guide rod (13), wherein the distance between the gripping elements (14) can be modified in a controlled manner by means of a drive (15), and wherein the gripping elements (14) are each interchangeably arranged and fixed via a coupling element (40) to the associated guide rod (13) thereof.

Gantry crane vehicle for performing one or more tasks in a photovoltaic array and method thereof. The gantry crane vehicle includes one or more base plates, and one or more tracks above the one or more base plates. Additionally, the vehicle includes one or more gantry assemblies configured to slide along the one or more tracks, and one or more first support trusses configured to support the one or more tracks above the one or more base plates. Moreover, the vehicle includes one or more second support trusses connected to at least some of the one or more first support trusses, and one or more storage cabinets located on the one or more base plates. The one or more storage cabinets include one or more top surfaces and one or more side surfaces, and the one or more top surfaces are located below the one or more tracks.

The invention relates to a handling device (1) comprising a drive carriage (2) that can be moved in relation to a beam (3), a scissor lift (7) comprising a plurality of scissor lift members (8) being arranged on the drive carriage (2) with the first end thereof, and a beam plate (11) that can move in relation to the drive carriage (2) by means of the scissor lift (7) being arranged on the second end of the scissor lift (7). A grip tool is arranged on the beam plate (11), and a drive (18) for actuating the scissor lift (7) is arranged on the drive carriage (2), as well as at least one guide bar (22), the guide bar (22) being coupled to the scissor lift (7) in a coupling point (K) for the guiding thereof, when the scissor lift (7) is moved.

A portable lifting apparatus is provided. The apparatus has a modular frame comprising a first frame member and a second frame member, which in combination support a load-bearing beam having a lifting device secured thereto above a lifting surface. The first frame member, the second frame member, and the lifting device are each removably secured to the beam such that the apparatus may be disassembled into constituent components for transport or storage. Each frame member may be configured to disassemble into constituent components comprising a base and two or more support rails. The apparatus may further comprise a counterbalance. The counterbalance may serve to balance load distribution when the apparatus in use and act as a storage receptacle for the first and second frame members, the beam, and the lifting device when the apparatus is disassembled.

An inverted carrier lift and method is disclosed. The inverted carrier lift includes a trolley movable along an overhead conveyor and a carrier for supporting a workpiece to undergo an assembly or manufacturing process. The carrier is movable relative to the trolley from a raised position to a lowered position by a motor engaged with a lifting mechanism on the trolley. On rotation of the motor, the carrier and supported workpiece is lowered or raised to position the workpiece in the workstation for processing. The workpiece may be disengaged by the carrier for support of the workpiece by one of many different fixtures depending on the processing. Following processing, the workpiece is re-engaged by the carrier, moved to a raised position and the trolley is transferred to a subsequent workstation.
