A tire unloader includes a mobile support structure, a robotic device supported by the mobile support structure, and a drive system. The drive system maneuvers the robotic device. The robotic device includes an engagement mechanism. The mobile support structure positions the robotic device to allow for engagement, lifting, and unloading stacks of tires. A remote user optionally controls the movement of the mobile support structure and the operational actions of the robotic device. A material conveyer optionally receives the unloaded material. A second robotic device located near the second end of the material conveyer optionally engages the unloaded tires on the conveyer and transfers the unloaded tires onto the transporting cart, which transports the unloaded material to a predetermined location.

An apparatus (600) for use in unpacking or packing shipping containers (700) includes at least one barrier part which provides a barrier to wheeled powered material handling equipment (1105). The barrier part can be positioned substantially transversely across an interior of a shipping container (700) at a desired position along the length of the interior of the shipping container, to provide a working area (1120) within the shipping container in which personnel may work on foot, and substantially impede or prevent entry of wheeled powered material handling equipment into the working area. The apparatus may be provided with an arrangement to substantially maintain its location in the desired position against forces resulting from impact by the powered material handling equipment operating within the shipping container.

A ramp assembly for unloading goods from an elevated platform that includes a platform and a ramp that can be rotated or orbited around a perimeter of a platform without rotating the platform. The ramp assembly uses an orbiting assembly that includes a rail and a rider in order to permit easy placement of a lower end of a ramp relative to the platform.

Methods, devices, systems, and non-transitory process-readable storage media for a computing device of a robotic carton unloader to identify items to be unloaded from an unloading area within imagery.

A power pack is located within a housing on the platform of a wind turbine generator tower. The power pack is supplied from a fuel tank. With the door of the housing open, the power pack may be removed for servicing and repair by using a U-shaped support structure to which an electric motor is mounted. Two support rails permanently located within the housing support the housed power pack. A chain attached to the power pack is driven by the motor to remove the power pack from the housing by sliding the power pack along the support structure. A pulley arrangement reduces the necessary torque. After removing the power pack from the housing, a crane is used to lift the power pack from the platform and to lower it down to a sea vessel. The crane may also be used in the refilling of the fuel tank by hauling a fuel line from a sea vessel up to the platform and connecting it to the fuel tank.

A trailer includes a load-bearing carrier frame which is guided on an undercarriage and includes a lateral longitudinal member and two cross members protruding at right angles from either end thereof. Between these, a central member is secured to the longitudinal member, parallel to the cross members, and a loading opening is formed opposite said longitudinal member. A lifting device is arranged, for mutual height adjustment purposes, between the carrier frame and the undercarriage. A load-clasping gripping unit may be arranged on the central member and may be displaced in the transverse direction between the longitudinal member and the loading opening.
