A cable stacker (20) having a first belt conveyor (21) for conveying the cable along a conveying direction X, the first belt conveyor (21) being designed to receive a belt, and the first belt conveyor (21) having a conveyor path with an input path portion and an output path portion. A main frame (23) is provided on which the first belt conveyor (21) is arranged, a counter barrier (40a) being provided for guiding the cable. In the region of the input path portion, the first belt conveyor (21) has a first drop barrier (31a) for preventing uncontrolled slipping of the cable from the conveyor path (22), the first drop barrier (31a) being movable relative to the counter barrier (40a) at least into an active position.

An apparatus for transferring and/or stacking products, the apparatus including a frame, a bar conveyor associated with the frame, the bar conveyor having a plurality of flight bars that are independently driven by a plurality of independent drivetrains, a lifting device having a lifting plate, the lifting device being located within the bar conveyor, and at least one pusher.

A method for transferring and/or stacking products, the method including providing a first plurality of products as a first unit, pushing the first unit onto a lifting plate, lowering the plate, providing a second plurality of products as a second unit, pushing the second unit onto the top of the first unit to create a stack.

A separator placer assembly is used with a lumber stacker, which creates a stack of lumber, includes a frame, a separator transfer assembly, and a plurality of transfer arm assemblies. The separator transfer assembly includes a continuous loop chain, preferably a plurality of continuous loop chains, with upper and lower reaches mounted to the frame. Separators are transferred to lugs on the chain at a first position along the lower reach. The plurality of transfer arm assemblies, each with first and second arms, is mounted to the frame beneath the lower reach at a transfer position downstream of the first position. A separator supported by the lugs is removed from the lugs by the arms and released onto the stack of lumber.

A system and a method are described for the intermediate storage of differently cut boards for a wooden structure, in particular a truss, with several compartments arranged laterally adjacent to one another. The compartments are each configured for receiving a set of boards for such a wooden structure, wherein a set is to be understood as the entirety of cut boards which are required for such a wooden structure. A feeding device fills the cut boards into the individual compartments and stacks them over one another therein. The compartments can be opened respectively at their underside, in order to remove the set of boards. A discharge device transports away the set of boards removed from the respective compartment.

The invention relates to a lifting system (1-5) for lifting elongated objects, comprising a sensor device (1) arranged to identify position and location of an elongated object, a lifting and rotating device (3), and a control unit (2) for controlling the movement of said lifting and rotating device (3) in response to signals from the sensor device (1) which indicate the position and location of the object. In order to lift elongated objects regardless of object's material, profile or position, said lifting and rotating device (3) is provided with an elongated gripping device (4) including a first gripping arm (4-1), and said control unit (2) is configured to control the lifting and rotating device (3) to insert a part of the first gripping arm into the object from one end of said object in order to lift and rotate the object with the inserted part.

A stacking system including an inverting arm arranged above the stacking system for selectively overturning a first elongated metal member into a second elongated metal member or not overturning the first elongated metal member into the second elongated metal member.

A stacking system including an inverting arm arranged above the stacking system for selectively overturning a first elongated metal member into a second elongated metal member or not overturning the first elongated metal member into the second elongated metal member.

A stacking machine for stacking elongated members in a stack comprises a frame and a pair of cooperating stackers mounted thereto distant from each other. Each of the stackers comprises a driven master wheel, a slave wheel mounted eccentrically from the master wheel, a stacking arm assembly concurrently mounted to the master wheel and the slave wheel causing the master wheel to drive the slave wheel and a stacking arm assembly mounted to the stacking arm assembly, the stacking arm assembly comprising a stacking blade extending substantially parallel to the master wheel and defining a stacking face. The stacking faces of the cooperative stackers define a stacking plane supporting a layer of elongated members to be stacked, whereby the layers are moved one at a time on a stack.
