A portable vehicle lift and methods of using the same are provided. The portable vehicle lift comprises a carriage, a head saddle, and a lift driver. The head saddle is movably connected to the carriage so that it is shiftable between a lowered position and a raised position. The lift driver supported on the carriage and configured to lift the head saddle.

A vehicle lift includes a mechanical lift including a platform and at least one extension being movable relative to the platform. Systems, devices and methods are disclosed.

A modular robot system which may be configured to accommodate packages of varying sizes is provided. The modular robot may include a base having omni-directional wheels and cameras and sensors, one or more modular containers, and a lid, which may be releasably linked together to form a small, medium or larger units. The base may include a lifting mechanism to vertically raise the robot to a desired height in alignment with a delivery vehicle. Moreover, retractable loading arms of the vehicle may be extended from the vehicle to engage with the robot to facilitate self-loading of the robot into the delivery vehicle.

A cooking appliance includes a cabinet that defines a vertical direction and an inner shell positioned within the cabinet. The inner shell defines a cooking chamber therein. The cooking appliance also includes an upper heating module positioned at or proximate to an upper wall of the inner shell. The cooking appliance further includes a movable platform mounted to the inner shell within the cabinet. The movable platform is configured to move along the vertical direction between a bottom position wherein the movable platform is at least partially flush with a bottom wall of the inner shell and an elevated position wherein the movable platform is positioned above the bottom wall of the inner shell.

A motorized cart assembly for use in gardening and other outdoor chores includes a first motor that is operationally coupled to a rear axle of a rolling chassis. The first motor is configured to selectively rotate the rear axle to locomote the rolling chassis. A lift module that is coupled to the rolling chassis is configured to selectively raise and lower an item that is positioned upon an upper plate of the lift module. A handle, which is coupled to at least one of the rolling chassis and the upper plate, is configured to be grasped in at least one hand of a user to steer the rolling chassis.

A movable battery replacing platform includes a travel-driving portion used for driving the movable battery replacing platform to move on the ground; a lifting portion mounted on the travel-driving portion, for lifting a battery during the replacement of the battery; and a battery mounting portion mounted on the top of the lifting portion, for placing a battery to be replaced or a replaced battery. The battery mounting porting is provided with a battery replacing device. The device can use an unlocking device to unlock a battery locked on the bottom of an electric vehicle, automatically aligning an unlocking point of a battery locking mechanism and realizing automatic unlocking in the movement. The angle of an upper board relative to the battery unlocking position can be adjusted by a movement actuating device, so that the unlocking point of the battery can automatically fit where the movable battery replacing platform remains still.

The present invention has a lifting table, comprising an upper platform, a lower platform, and at least one group of lifting component positioned between the upper and lower platforms and used for adjusting the height of the upper platform relative to the lower platform; the lifting table further comprises elastic elements and sliding components sliding fit on the upper or lower platform; the sliding components are connected with the elastic elements for sliding on the upper or lower platform under the effect of elastic forces from the elastic elements; each sliding component has a push part, the lifting component exerts an acting force to the push part so that the sliding component overcomes the elastic force of the elastic element to slide along the upper or lower platform, and is simple and labor-saving in operation and good in user experience.

The invention provides a mechanically unlocked automobile lifter includes a power device, oil cylinders and lifting platform devices. The lifting platform devices include two lifting platform devices having a same structure. Each lifting platform device includes an upper table and a lower plate having a scissor-type support arm disposed therebetween. The scissor-type support arm includes first and second support arms, ends of the first support arm are respectively slidably connected with the upper table and fixedly connected with the lower plate, ends of the second support arm are respectively fixedly connected with the upper table and slidably connected with the lower plate. The lower plates have first and second beams disposed therebetween. The oil cylinders are disposed on the scissor-type support arms of the two lifting platform devices, and the power device is connected with the oil cylinders. Each lower plate is disposed with a mechanical safe locking device.
