Various embodiments illustrated herein disclose a container unloader device. The container unloader device comprises a platform to receive a container, wherein the container comprises a package. The container unloader device also comprises a front panel configured to move between a raised orientation and a lowered orientation, wherein when the front panel being is in the raised orientation, the front panel is orthogonal with respect to the platform, and when the front panel is in the lowered orientation, the front panel and the platform form a continuous surface. The platform can be pivoted from a first angle to a second angle, that is greater than the first angle. The package leans against the front panel the front panel is in the raised orientation. The package is released on a surface of a conveyor when the front panel is in the lowered orientation.

A conveyor device, comprising a) a plurality of rack elements arranged in a first row to define a first conveyor track. The conveyor device also comprises b) a plurality of rack elements arranged in a second row to define a second conveyor track. The conveyor device includes c) a robot unit with a traction device and a driving device, wherein said traction device is adapted to move said robot unit along said first or said second conveying direction and said driving device is adapted to engage said coupling interface of said movable carrier device to drive said movable carrier device. The conveyor device also includes d) a cross traverse rack element adapted to take up said robot unit, wherein said cross traverse rack element comprises a traverse movable load carrying device having an upper traverse load surface adapted to take up an object and a traverse coupling interface.

A road barrier transfer machine includes an improved capstan control system that reduces unwanted migration of road barrier spans without requiring inaccurate visual observations and reliance on outdated scripts. The barrier transfer machine includes a moveable chassis, an entry snout, an exit snout, a conveyor system, a capstan system, and the capstan control system. The capstan control system automatically operates the capstan system or provides instructions to an operator of the machine to maintain the tension and compression of a road barrier span within desired ranges to reduce unwanted migration of the span.

A roller conveyor system for conveying material may include a frame and roller conveyors arranged on the frame. The roller conveyor system is configurable in an operating state and in a maintenance state. At least one of the roller conveyors is arranged in an operating position in the operating state and in a maintenance position that is different from the operating position in the maintenance state. In the maintenance position, a region is then advantageously freed up, which can be used to perform maintenance. In addition, a method for transferring such a roller conveyor system from an operating state into a maintenance state may involve transferring one of the roller conveyors from the operating position into a maintenance position different from the operating position.

The invention relates to a method for assembling a roller conveyor having rollers for products, each having a cylindrical roller body and a first and second support element on opposite ends of the roller body, the second support element having pulley means; providing a frame having a first and second frame part for mounting therebetween the rollers; and, for the purpose of mounting a roller to the frame: mounting the first support element to a first mounting provision of the first frame part; passing a drive element and a further drive element over the pulley means of the roller; tensioning the drive element by exerting a force on the roller by means of a tensioning device; mounting the second support element of the roller to a second mounting provision of the second frame part while keeping the drive element tensioned; and removing the tensioning device from the roller.
