According to one embodiment, an object to be transported by an automatic guided transportation vehicle includes: a housing having an entry route through which the automatic guided transportation vehicle enters; a marker that can be recognized by a sensor provided in the automatic guided transportation vehicle; and a marker holder configured to hold the marker retractably at an initial position where the marker contacts with the automatic guided transportation vehicle in the entry route.

Some aspects of the present disclosure provide a modular vehicle frame for a material handling vehicle. In some configurations, the modular vehicle frame includes a battery compartment, a handle configured to control a speed and direction of a traction wheel, and a mounting assembly configured to selectively quick-connect to a material handling attachment. In some configurations, the mounting assembly includes a mounting plate having a first side and a second side, at least one pivot block extending from the first side of the mounting plate and configured to provide a pivotal interface with the material handling attachment, and at least one locking latch attached to the second side of the mounting plate and configured to provide a selective locking interface with the material handling attachment.

A pallet sled includes a lower frame and an upper frame. A plurality of pivot arms pivotably connect the upper frame to the lower frame. The upper frame is movable between a lowered position and raised position. The upper frame is spaced further from the lower frame in the raised position than in the lowered position. The upper frame is rotated slightly relative to the lower frame when moved from the lowered position to the raised position. In the example embodiment, the upper frame is rotated approximately 1.5 degrees to approximately 2.0 degrees toward the upright handle of the pallet sled.

Lifting device for pallet goods for loading and unloading of a transport pallet such as a standard pallet, for example a euro pallet. The lifting device comprises a support frame, a tine assembly liftable mounted to the support frame of at least two, preferably four, tines having a parallel direction of extension for lifting and receiving the transport goods from the transport pallet and/or for depositing the transport goods onto the transport pallet. A tine spacing of two tines is adapted to a gap spacing of two longitudinal gaps and at least two tines are form-fitted with regard to the at least two longitudinal gaps such that they can access the longitudinal gaps in the longitudinal direction.

The present disclosure provides a conveyance system and the like capable of preferably conveying a conveyed object in accordance with a state of the conveyed object. The conveyance system includes a conveyance robot, a drive controller, which is a controller, an image data acquisition unit, and a setting unit. The conveyance robot conveys the conveyed object. The drive controller controls an operation of the conveyance robot. The image data acquisition unit acquires image data obtained by capturing images of the conveyed object. The setting unit sets an operation parameter of the conveyance robot in the drive controller based on the acquired image data.

A conveyance system and the like capable of preferably conveying a conveyed object is provided. The conveyance system includes a conveyance robot, which is a conveyance apparatus, a drive controller, which is a controller, an information accepting unit, and a setting unit. The conveyance robot conveys the conveyed object. The drive controller controls an operation of the conveyance robot. The information accepting unit accepts an input from a user regarding information indicating stability of the conveyed object in a conveyance state. The setting unit sets an operation parameter of the conveyance apparatus in the drive controller based on the accepted information.

A power-assisted steering mechanism of an electric pallet truck includes an operating mechanism, a power assistor assembly, a driving mechanism and a mounting bracket. A handle and a handle seat of the operating mechanism are connected. The power assistor assembly includes a power assist mechanism and a controller. The power assist mechanism is electrically connected to the controller. An input shaft at an upper end of the power assist mechanism is drivably connected to a lower end of the handle seat. The mounting bracket includes a mounting plate and a mounting seat. An outer casing of the power assist mechanism is fixedly connected to the mounting plate. The driving mechanism includes a drive connecting shaft, a reduction gearbox, a driving wheel and a driving motor.

A pallet jack includes a base and a pair of tines extending from the base. The pair of tines including a first tine and a second tine. A load wheel supports an outer end of each of the pair of tines. Each load wheel is configured to move toward and away from the respective tine to raise the tine off a floor on which the load wheel is supported. The first tine including a support surface configured to selectively be a lowermost surface of the tine to facilitate lateral displacement of the first tine.

A pallet sled includes a base and a pair of tines extending from the base. A load wheel supports outer ends of each of the tines. A wheel supports the base. At least one motor is configured to drive the base wheel or at least one of the load wheels for driving the pallet sled. The motor may be a hub motor inside the base wheel or the load wheel.

A pallet sled includes a lower frame and an upper frame. A plurality of pivot arms pivotably connect the upper frame to the lower frame. The upper frame is movable between a lowered position and raised position. The upper frame is spaced further from the lower frame in the raised position than in the lowered position. The upper frame is rotated slightly relative to the lower frame when moved from the lowered position to the raised position. In the example embodiment, the upper frame is rotated approximately 1.5 degrees to approximately 2.0 degrees toward the upright handle of the pallet sled.
