Abstract: A handcart may include: a support frame; a container; a lock member configured to move between a locking position at which the lock member restricts rotation of the container relative to the support frame and an unlocked position at which the lock member allows the rotation of the container relative to the support frame; and a retainer member configured to move between a retaining position at which the retainer member restricts a movement of the lock member from the unlocked position to the locking position and a non-retaining position at which the retainer member allows the movement of the lock member from the unlocked position to the locking position. The lock member may be configured to move from the locking position to the unlocked position and be maintained in the unlocked position by a movement of the retainer member from the non-retaining position to the retaining position.

Abstract: A handcart may include a frame; a drive wheel rotatably supported by the frame about a rotation axis extending in a right-left direction; a prime mover configured to rotate the drive wheel; a bracket pivotably supported by the frame about a pivot axis extending in an up-down direction; and a non-drive wheel supported by the bracket about a rotation axis extending in a direction perpendicular to the up-down direction. The non-drive wheel may include a first non-drive wheel and a second non-drive wheel, and the first non-drive wheel and the second non-drive wheel may be configured to be rotatable independent of each other.

Abstract: A handcart may include: a front wheel; a rear wheel; a support frame supporting the front wheel and the rear wheel; a receptacle pivotable relative to the support frame; a load sensor configured to detect a load applied to the rear wheel; and a control unit. When the load detected by the load sensor is less than or equal to a predetermined load, the control unit may be configured to determine that the rear wheel is predicted to lift from a ground.

Abstract: A handcart may include a support frame, an actuator, a rotating frame configured to be rotated relative to the support frame by the actuator and a container configured to be rotated relative to the support frame. The container may be configured to be rotated with the rotating frame relative to the support frame when the rotating frame is rotated relative to the support frame by the actuator. The rotating frame may be rotatable up to a position at which an angle between the support frame and the rotating frame becomes a first rotation angle. The container may be rotatable up to a position at which an angle between the support frame and the container becomes a second rotation angle, the second rotation angle being greater than the first rotation angle.

Abstract: A handcart may include a chassis unit and a container unit configured to be detachably attached to the chassis unit. The chassis unit may include a front wheel unit rotatably supporting a front wheel; a rear wheel unit rotatably supporting a rear wheel; a chassis frame extending in a front-rear direction and supporting the front and rear wheel units; and a prime mover configured to rotate at least one of the front wheel and the rear Wheel as a drive wheel. The container unit may be selected from a group including at least a first container unit and a second container unit. The first container unit may include a first container and a first container frame extending in the front-rear direction and supporting the first container, The second container unit may include a second container and a second container frame extending in the front-rear direction and supporting the second container.
