The carts may include drive motors and the pallets may be nestably stackable.

A hand truck that includes a carriage, and an elongated frame that connects to a front side of the carriage and is configured to pivot in relation to the carriage. The hand truck also includes a stabilizer plate configured to extend outward from the front side of the carriage to stabilize the hand truck as the elongated frame pivots in relation to the carriage, and to retract inward toward the front side of the carriage.

A seal head assembly includes a plurality of heat seal plates defining a corresponding plurality of heating areas, each heat seal plate including a heating element to independently control the temperature of the corresponding heating area.

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 disclosure described herein relates to compact lift-and-steer wheel assemblies. An assembly includes a housing, a rotational assembly, a linkage, and at least one wheel. The wheel is pivotably coupled to a bracket of the rotational assembly via a wheel mount and a pivoting member. The linkage is coupled to the pivoting member of the rotational assembly via a steering member. The assembly is configured to rotate the wheel through an opening of the housing from a first position to a second position based on the linkage translating a first distance within the housing. The assembly is configured to pivot the wheel about the rotation assembly from the second position to a third position based on the linkage translating a second distance within the housing. An adjustable cantilever wheel system is configured to suspend the assembly above ground level to allow insertion at a raised height.

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.

The disclosure described herein relates to compact lift-and-steer wheel assemblies. An assembly includes a housing, a rotational assembly, a linkage, and at least one wheel. The wheel is pivotably coupled to a bracket of the rotational assembly via a wheel mount and a pivoting member. The linkage is coupled to the pivoting member of the rotational assembly via a steering member. The assembly is configured to rotate the wheel through an opening of the housing from a first position to a second position based on the linkage translating a first distance within the housing. The assembly is configured to pivot the wheel about the rotation assembly from the second position to a third position based on the linkage translating a second distance within the housing. An adjustable cantilever wheel system is configured to suspend the assembly above ground level to allow insertion at a raised height.

A pallet sled includes a lower frame and a plurality of wheels supporting the lower frame. An upper frame is configured to support a pallet thereon. A ratchet is configured to lift the upper frame relative to the lower frame. A handle is configured to operate the ratchet to lift the upper frame relative to the lower frame. The handle may be pivotable relative to the lower frame. The ratchet may include a gear and a pawl. The ratchet may also be configured to selectively lower the upper frame. As another option, one or more of the handle, the upper frame or the plurality of wheels are reconfigurable between an extended position and a retracted position.

Luggage that may be mechanically integrated with a platform, including a piece of luggage including a slit through which the piece of luggage is integrated with a platform for the piece of luggage, a handle fastened to the piece of luggage, for pushing or pulling the piece of luggage, luggage wheels fastened to a first outer surface of the piece of luggage, for rolling the piece of luggage, and a release mechanism extending from the luggage unit to the platform, through the slit, for unlocking the platform, wherein the platform locks and unlocks such that the platform is free to be raised and lowered when it is unlocked, and is not free to be raised and lowered when it is locked.

A scissor lift for raising and lowering a heavy object, including an upper platform for supporting a heavy object, including a release mechanism, and guided rollers mounted on axles, a lower frame including guided rollers mounted on axles, a scissor lift mechanism fastened to the axles of the upper platform guided rollers and to the axles of the lower frame guided rollers, that raises and lowers the upper platform, a locking mechanism including protrusions protruding outward of the upper frame, each protrusion corresponding to a different height of the scissor lift mechanism, wherein at least one guided roller within the upper platform includes a spring-loaded pin for engagement in the protrusions, thereby locking the scissor lift mechanism into place at a height corresponding to the protrusion into which the spring-loaded pin is engaged, and a release mechanism that unlocks the scissor lift mechanism.
