Abstract: Disclosed is a disengageable gearbox for an electric pallet truck, including a box body and a box cover assembled with the box body. The box body and the box cover are assembled to form a mounting chamber. A gear set is mounted in the box body. A disengagement mechanism is provided in the gear set. The disengagement mechanism achieves engagement or disengagement of the gear set, so that the gear set transmits or terminates torque output. The disengagement mechanism includes a key sleeve. An inner key is engaged with a key shaft. An outer key is engaged with a keyway in a transmitting gear. The key sleeve is movable on the key shaft along an axial direction. When the outer key of the key sleeve is disengaged from the keyway in the transmitting gear, torque is not transmitted between the transmission gear and the key sleeve.

Abstract: Disclosed is a dual-purpose handling truck, which can be electrically controlled to walk or manually pushed and pulled to walk, and has two walking modes. A dual-purpose handling truck includes a front frame; a driving assembly and a lifting assembly are connected below and above the rear frame plate, respectively; the driving assembly includes a walking mechanism and a power mechanism for driving same; the walking mechanism includes a driving frame, on which a driving wheel is installed; the power mechanism controls a gear box to drive the driving wheel to rotate, so that the handling truck is electrically controlled to walk; the gear box is provided with a separation mechanism, which makes gears lose transfer torque and enables the driving wheel to rotate freely, so that the handling truck is manually pushed and pulled to walk; and the lifting assembly realizes the lifting of the handling truck.

Abstract: A walking-type electric carrier, comprising a handlebar, a driving mechanism, and a carrier frame that is connected to the driving mechanism; the handle bar comprises an armrest cross-bar, a vertical post that is vertically connected to the armrest cross-bar; the vertical post is connected to the driving mechanism; the vertical post is provided with a lifting handle, and the armrest cross-bar is provided with a detachable handle component; the handle component comprises a handle base and a handle body; the handle base and the handle body are detachably connected; the driving mechanism is controlled by the handle body to propel the carrier to move.
