The assembly of the disclosure includes two inclined side rollers and two central rollers, each one of the rollers being mounted around a respective shaft. The shaft of each side roller has an upper end hinged to a respective support portion arranged on one side of the conveyor belt, the shaft of each central roller having ends mounted on opposite sides of a rocker frame. Each one of the opposite sides of the frame has a median portion hinged, in an suspended way, at the lower end of the shaft of a respective side roller.

A transport unit, a material transfer structure and a material transfer unit for a mobile haulage arrangement are arranged for continuously conveying fragmented material in a conveying direction. A mobile haulage arrangement and a method for continuously conveying fragmented material in a conveying direction is also disclosed. The transport unit includes two ground transportation structures and a support frame suitable for fitting a belt of an enclosed belt conveyor thereunder. The ground transportation structures has at least one height adjustment device, wherein the support frame comprises at least one connector, which is arranged for connecting a support structure thereto. The height adjustment devices are arranged to vary the position of at least a portion of the support frame in relation to the ground transportation structures.

A fitting for attaching to a threaded connection of a pipe, in particular a water pipe, includes a basic body, a threaded portion, and a sealing body arranged on the threaded portion. The basic body has a pressing surface on the side situated opposite to the threaded portion. Also disclosed is a method for attaching a fitting to a threaded connection of a pipe.

The disclosure relates to a support structure for supporting a belt of an enclosed belt conveyor between two transport units and a corresponding method. The support structure between two transport units includes a first end element having a main extension in a longitudinal direction, a width extension in a width direction orthogonal to the longitudinal direction, and a height extension in a height direction orthogonal to the longitudinal and the width direction. At least one guide assembly is arranged to engage opposite longitudinal edges of the belt. A first telescopic element is connected to the first end element, wherein an outer end of the first end element has a first end connector arranged to form a connection with a first transport unit.

A trough-belt conveyor with adjustable bearing support wings and methods for operating the conveyor to sort or destack articles. The conveyor includes a flexible conveyor belt supported in a series of support beds. Adjustable support beds have a base bearing member flanked by a pair of bearing wings. One or both of the wings are adjustable to raise or lower the sides of the belt above and below the plane of the center of the belt supported atop the base member.

An idler support assembly is configured to support a conveyor belt thereon. The idler support assembly includes a frame having a first end and a second end, and a first idler roller coupled to the frame between the first and second ends. The first idler roller is configured to rotate about a first roller axis. The idler support assembly also includes a second idler roller coupled to the frame between the first and second ends. The second idler roller is configured to rotate about a second roller axis. The idler support assembly further includes a first base pivotably coupled to the first end of the frame about a first pivot axis, and an adjustable support selectively coupled to the second end of the frame in a plurality of positions. Each of the plurality of positions defines an angle in which the frame extends relative to the first base.

A lateral guiding device includes a support and an idle guide roller which is able to be mounted in a removable manner on the support between a first part making it possible, in an operational position, to support one end of the axle of the roller at an upper point, and a second part making it possible to support the other end of the axle of the roller at a lower point. The first part of the support is movable between the operational position and a retracted position. The support includes a retaining element which, when the first part is in the retracted position and does not support the roller, has the function of vertically retaining the roller in a removal position in which the second end of the axle of the roller is supported at the lower point by the second part.
