In one example, a mother cart is provided that is suitable for transporting a daughter cart. The mother cart includes a base frame having a group of wheels configured to allow the mother cart to be moved. The base frame, in turn, includes a loading bay for receiving the daughter cart, and a support surface for supporting the daughter cart. Finally, the base frame includes a primary restraint mechanism for engaging and securing the daughter cart in the loading bay.

A tugger cart includes a tugger frame having a first side member, a second side member, and a locking member disposed in between the first side member and the second side member. A first roller assembly is coupled to an inner surface of the first side member and a second roller assembly coupled to an inner surface of the second side member. Each of the first roller assembly and the second roller assembly include a roller assembly frame and a plurality of wheels rotatably coupled to the roller assembly frame. The roller assembly frame supports the plurality of wheels at a slant that declines from a rear of the tugger frame to a front of the tugger frame. An actuator is configured to raise and lower the first roller assembly and the second roller assembly relative to the first side member and the second side member respectively.

The present invention relates to a vehicle, which is used in particular for transporting objects, in particular workpieces. Here, preferably one or more receiving elements for receiving one or more objects are provided.

The present disclosure discloses an unmanned movable platform that includes one or more unmanned moveable vehicles that are capable of operating different modes. Under the following mode, the unmanned movable vehicles use their vision sensors to follow the operator while using other sensors to collect environmental information to smartly avoid obstacles. Under the autonomous navigation mode, the unmanned movable vehicles may autonomously navigate along a pre-stored route to complete a predefined task, such as loading or discharging an inventory.

A conveyor system, comprising a conveying section and at least one conveyor carriage that carries a drive of its own, and with the drive is movable along the conveying section, wherein the drive includes a drive motor and a separation device, by means of which the power flow between the drive motor and the conveying section can be separated. In order to move a left-behind conveyor carriage out of a difficult-to-reach segment of the conveying section, the separation device is configured to be activated by a separating carriage that follows the conveyor carriage along the conveying section and/or precedes the conveyor carriage along the conveying section in order to separate the power flow between the drive motor of the at least one conveyor carriage and the conveying section.

A tugger cart includes a tugger frame having a first side member, a second side member, and a clasping member. A plurality of wheels are coupled to a bottom of the tugger frame. Each of the first side member and the second side member include a plurality of roller wheels rotatably coupled to an inner side and rotatable about a horizontal axis. The plurality of roller wheels align along an angled plane that declines from a rear of the tugger frame to a front of the tugger frame. The clasping member includes at least one fixed arm, at least one telescoping arm, an actuator, and a grab arm extendable and retractable from the at least one telescoping arm. The actuator converts the telescoping arm between an extended position and a retracted position.

A slide-out undercarriage mounted on an underside of a first trailer pulled by a highway tractor. The slide-out undercarriage is adapted for attaching a rear of the first trailer to a front of a second trailer. The slide-out undercarriage includes a fixed undercarriage frame mounted on an underside of a first trailer. A front axle with front wheels is mounted on a front axle frame and a rear axle with rear wheels is mounted on a rear axle frame. The rear axle frame includes a fifth wheel adapted for engaging a king pin on the front of the second trailer. A pair of first slide out tubes are attached to the front axle frame. A pair of second slide out tubes are attached to the rear axle frame. The first and second slide out tubes provide for allowing an operator of the first trailer to adjust the front and rear axles in various load positions under the first trailer when pulling the second trailer.

According to some embodiments, an improved tugger and rider cart assembly system is presented. The system comprising a tugger cart with a central space to receive a rider cart; the tugger cart having both front side and rear side pluralities of transport wheels approximately parallel to, but not touching, ground; a front side and a rear side loading wheel positioned closer to the ground than the transport wheels; a rider cart having a first wing and a second wing, both wings having a curved portion; and wherein the loading wheels and wing curved portions can be operatively connected to allow a user to move the rider cart onto the tugger cart thereby allowing the tugger cart to transport the rider cart.

A conveyor system has a conveyor section, at least one first moving trolley which carries along a dedicated drive and is movable with the latter along the conveyor section and which has a first trolley parameter, and a controller which, taking into consideration the first trolley parameter triggers various actions with the aid of waypoints along the conveyor section. For more flexible use of the conveyor system, at least one second moving trolley having a second trolley parameter differing from the first trolley parameter is provided, and the controller is designed to place at least one waypoint along the conveyor section, at which waypoint a certain action is triggered, for the second moving trolley at a different position along the conveyor section than for the first moving trolley.
