The object carrier for carrying objects is provided, wherein the engaging portions of the shelf member are engaged with the engaged portions of the frame member from top to bottom in the vertical direction to constitute the engagement state between the shelf member and the frame member, the connection line between the engaged portions constitutes an engagement direction, and the shelf member moves in an engagement releasing direction perpendicular to the engagement direction on a horizontal plane to release the engagement state with the frame member. The lift for removing objects from the object carrier is provided, wherein the bearing portion moves in the vertical direction through the lifting portion and bears the shelf member on which the object is placed under the object carrier, and the bearing portion moves in the horizontal direction through the sliding portion, so as to remove the shelf member and the object altogether.

The present invention discloses a flatbed trolley with casters capable of not folding when a handle rotates, which comprises a bearing frame (1), a handle (2), rotary frames (3), wheel carriers (4), and casters (5). The handle (2) is fixed at an upper portion of the bearing frame (1) via a connecting structure. The connecting structure comprises a left joint (14), a right joint (15), a left gear seat (12), a right gear seat (13), and a handle locking mechanism. The handle locking mechanism comprises a cross bar (7), locking blocks (8), connecting bars (9), switches (10), and a spring (11). The cross bar (7) is a hollow tube with an end being supported on the left gear seat (12) and the other end being supported on the right gear seat (13). An end of the cross bar (7) is provided with the locking block (8), wherein the locking block (8) is slidable along an extension direction of the cross bar (7). An end of the locking block (8) is connected to an end of the connecting bar (9), and the other end of the locking block is capable of inserting into the left joint (14) and the left gear seat (12) to lock them. The connecting bar (9) is installed within a hollow part of the cross bar (7), and the other end of the connecting bar is connected to the switch (10). Similarly, the other end of the cross bar (7) has a same structure. The spring (11) is provided between two switches (10), which thereby enables the casters be capable of not folding when the handle rotates.

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 modular cart includes a cart frame with a top and a bottom. A platform is secured to the top of the cart frame. Wheels are secured to the bottom of the cart frame. Receiver assemblies are secured to the cart frame. A cart module includes at least one handle with a lower end and an upper end. A shank is located at the lower end. The shank is removably secured within a receiver assembly secured to the cart frame.

A transport structure, such as a cart or dolly having a handle moveable from a first position to a second position is disclosed. In the first position, the handle extends outward from an edge of the cart or dolly and can be used for pushing or pulling the cart or dolly. In the second position, the handle is moved to extend generally parallel to an upper surface of the cart or dolly so that it can be stored or transported with the cart or dolly.

A transport structure, such as a cart or dolly having a handle structure that can be inserted laterally into an opening in the transport structure is provided. The handle structure includes a first connection hook portion and a second connection hook portion moveable from a first spaced position to a second spaced position greater than the first spaced position. The handle structure includes a hinged beam that enables the hook portions to contract and expand from the first position to the second position.

A method of making a shopping cart includes forming a frame capable of supporting a plurality of basket assembly types, selecting from the plurality of basket assembly types a first basket assembly defining a first basket assembly type; and connecting the first basket assembly to the frame.

A connectable dolly having a platform with an upper surface, a peripheral edge and a bottom surface, a plurality of caster wheels extends from the bottom surface and are attached thereto, and a connector element is mounted to the platform proximal the peripheral edge and is moveable from a stored position to a deployed position, the connector element having a proximal end and a distal end, the distal end having an engaging member dimensioned for removably connecting the connectable dolly to a second dolly.

A stackable cart for transport large panels is configured to be stackable. The stackable cart has a base frame having an open quadrilateral shape with a short side and two lateral sides coupled to the short side. The stackable cart further includes a load frame for supporting sides of the panels, and a support frame for supporting the load frame, with the load frame and the support frame coupled to the base frame. The stackable cart further includes a platform for supporting edges of the panels, with the platform including a rotatable platform, a tilt platform, or a flat platform configured to enable the stacking of the stackable cart.
