A hand truck includes a base that is able to roll along the ground underlying the base and a push handle coupled to the base. A pivotable toe plate is coupled to a lower end of the base.

A lifter device includes: a pole; a lifting member configured to be guided by the pole; a motor configured to generate power used for ascending and descending of the lifting member; a transmission mechanism configured to transmit the power of the motor to the lifting member; and a preventing member configured to prevent the descending of the lifting member when the power is not transmitted.

A lifter device includes a pole, a lifting member guided by the pole, a motor that generates power used for ascending and descending of the lifting member, a controller that controls the motor, a case that is fixed to at least a portion of the pole and accommodates the motor and the controller, a transmission mechanism that transmits the power of the motor to the lifting member, and a battery mounting portion that is provided on the case and to which a battery pack is mouted to supply power to the motor.

A transportation device configured to detachably engage with units, such as modular units, is provided. The transportation device is configured to actuate between an open position and a closed position. In the open position the transportation device is configured to couple to and help move one or more units, such as modular units. In the closed position, the transportation device is configured to engage with units, such as modular units, for easier movement of the transportation device.

The embodiments described herein are directed to a cart and related methods. The cart includes a base, a plurality of wheels connected to the base, a lower platform mounted to the base, a back panel mounted to the base, a set of lateral panels, an opening side of the cart, and a linking mechanism. The set of lateral panels defines an interior space of the cart. At least one of the set of lateral panels includes a shelf. The shelf is pivotally mounted to a rectangular frame of the at least one of the set of lateral panels. The opening side of the cart is open to provide access to the interior space of the cart. The linking mechanism is configured and arranged to connect the cart to another cart.

A cart assembly includes a base with wheels, a shelf support structure orthogonally arranged with respect to the base, one or more shelves supported by the support structure, and a swivel mechanism. The swivel mechanism is coupled to the base and the shelf support structure to provide an axis of rotation, such that the shelf support structure and the shelf or shelves are selectively rotatable with respect to the axis. The swivel mechanism may include a race that defines a socket on a circumference of the race. A pin is selectively engageable with the socket to prevent rotation of the race and the support structure. The shelf may include a thermoformed plastic tray, or three shelves arranged at three different levels of the shelf support structure. Some of the shelves may fold against and secure to the shelf support structure.

A cart includes: a side frame portion extending across a width of the cart; a first end portion pivotally mounted on a first end of the side frame portion; a second end portion pivotally mounted on a second end of the side frame portion; a shelf movably mounted on one of the side frame portion, first end portion, and second end portion. In an unfolded configuration, the first end portion and the second end portion are unfolded relative to the side frame portion and the shelf is substantially horizontal for locating items thereon. In a folded configuration, one or both of the first end portion and the second end portion is folded against the side frame portion.

A transport cart 40, which consists of a U-shaped bow, between the vertical struts of which horizontal struts in the form of round pipes are arranged one over another in levels. These transverse struts have multiple upwardly protruding holding elements, for example, in the form of inclined pins or journals, on which carrying bags are fastenable using the handles thereof.

A collapsible cart having a frame that extends from a handle to an opposing wheel housing is provided. The wheel housing may provide a plurality of wheel, each wheel independently movable between a folded condition nested therein and an extended condition operably protruding from the wheel housing so that a user manipulating the handle steers the collapsible cart along a supporting surface. A plurality of collapsible brackets and crates may be provided along the frame so as to be movable between an operable configuration for transporting objects and a collapsed configuration for storage of the collapsible cart.

A stocking cart includes a base structure having an opening configured to receive forks of a forklift; a plurality of wheels connected to the base structure; a back panel mounted to the base structure and extending opposite from the plurality of wheels; first and second lateral panels mounted to the base structure, the first and second lateral panels and the back panel defining an interior space of the cart; and at least one strap provided on an open side of the cart to provide access to the interior space of the cart, the at least one strap being configured to hold one or more items inside the cart. The cart also includes a linking mechanism configured to connect the cart to another cart.
