A wheel roller for a chain conveyor of an automated carwash has a more robust configuration due to a direction connection of the wheels to the carrier link. The wheel roller contains a carrier link forging having a main body with a carrier link formed as an unitary component, pins secured to the main body in a fixed, non-pivotable manner, and wheels attached to the pins.

A method involves conveying tissue logs in a saw conveyor. The conveyor has independent lane control cutting and variable conveyor flight length. In one aspect of the method a first tissue log is received in a lane of a conveyor. With a first log advancement member, the first tissue log is advanced in the lane of the conveyor for cutting with a tissue log saw. A second tissue log is received in the lane of the conveyor when the first tissue log has advanced sufficiently in the lane to accommodate the second tissue log in the lane. With a second log advancement member, the second tissue log is advanced in the lane of the conveyor for cutting with the tissue log saw independently of the step of advancing the first tissue log in the lane. The conveyor may also have multiple lanes.

A conveyor system for translating objects is disclosed, each object with vertical protrusions extending upward and/or downward from one or more sides of the object. The conveyor system can accommodate structural members such as roof truss members, on which connector plates are affixed and from which the connector plates protrude vertically up, down, or both. The conveyor system may have a slide or some other support for the objects. The slide or other support may be narrow. The slide or other support can be tall, relative to an object. The conveyor system may have an engagement tool driven by an overhead carriage to translate the objects along the slide or other support. The engagement tool may be narrow. The engagement tool can be tall, relative to an object.

A firewood handling device for firewood pieces comprises a conveyor including one or more rotating, endless chains, wherein the conveyor extends from an input end to an output end. The conveyor chains are provided with carriers which project outwards from the outer sides of the chains and extend across and on a distance from each other in relation to the longitudinal extension of the conveyor such that spaces are formed between the carriers into which firewood pieces can be positioned. The carriers are formed with at least two, not cut through slots or recesses from below as well as from above which overlap each other. The conveyor in its output end is provided with at least two inner guiding members as well as with at least two outer guiding members.

A conveyor system for advancing tissue logs has a first log advancement member that conveys a lead tissue log toward a discharge end of a lane via a first drive, and a second log advancement member that conveys a successive tissue log after the lead tissue log toward the discharge end of the lane via a second drive. A controller is coupled to the first and second drives. The controller is adapted and configured to control: the first drive to move the first log advancement member between a start and finish position, the second drive to move the second log advancement member between the start and finish position, and the first drive independently of the second drive. A plurality of like lanes may be provided and the controller may also control the first and second drives of one lane independently of the first and second drives of another lane.

A dollie assembly for a vehicle wash includes a center link configured for attachment to a drive mechanism of the vehicle wash and having a throughhole with a first bushing extending therethrough along an axis between opposite ends with cylindrical bearing surfaces on opposite sides of the center link. A tire pushing roller is disposed on each of the bearing surfaces for rotation about the axis. A pair of track rollers are supported for rotation about the axis. The track rollers are disposed on an opposite side of the pair of tire pushing rollers from one another such that the pair of tire pushing rollers are between the pair of track rollers. The pair of track rollers are rotatable about the axis independently from pair of tire pushing rollers.

An article transport device includes a transport mechanism which is configured to support, from below, a container being transported and to transport the container along a transporting path, and a housing which forms an accommodating space in which at least a part of the transport mechanism is housed. The housing has one or more support plates, a plurality of brackets, and a housing panel. Each of the one or more support plates is a plate-shaped member extending along the transporting path and is configured to support the transport mechanism from below. A lower end portion of each of the plurality of brackets is attached to a corresponding one of the one or more support plates such that the plurality of the brackets are spaced apart from one another along a direction along the transporting path, outside the accommodating space along the lateral width direction. When the housing panel is not attached to the at least one of the plurality of brackets, the housing is provided with a communicating opening for allowing communication between a space inside and a space outside the accommodating space. The vertical dimension of the communicating opening is set to be a dimension that corresponds to a vertical dimension of the at least one of the plurality of brackets.
