The present invention provides electric pullet truck in the technical field of land transportation equipment. The electric pullet truck comprises a frame including two forks; a steering drive assembly including i) a drive wheel component disposed behind the frame; ii) an oil cylinder component to drive the forks up, which includes an cylinder body and a plunger which could telescopically move within the cylinder body, wherein the cylinder body is fixedly connected with the drive wheel component; iii) a supporting seat component including an annular sleeve and two support arms extending from both sides of the annular sleeve, wherein the annular sleeve is covered outside of a lower portion of the oil cylinder body; and iv) a handle seat component fixedly connected with an upper portion of the cylinder body. The electric pullet truck of the invention has advantages like a high degree of integration and smooth steering.

Included is a stabilizer wheel assembly that may assist in stabilizing a medical device during a medical procedure. A medical device may comprise a body; and a plurality of stabilizer wheel assemblies coupled to the body, wherein the stabilizer wheel assemblies each comprise a motor assembly and a stabilization leg, wherein the motor assembly is configured to drive the stabilization leg onto a contact surface to stabilize the body.

A portable powered roller assembly configured to impart a motive force to a wheeled vehicle or structure consists of a roller mounted in a rolling support structure. The roller is rotationally driven by a battery-powered drive unit coupled through a torque multiplying transmission, and is configured for engagement with the circumferential surface of a vehicle wheel. Rotational movement of the roller in engagement with the circumferential surface of the vehicle wheel draws the powered roller assembly towards, and under, the curved circumferential surface of the vehicle wheel, imparting a force to the vehicle wheel which include both a lifting force perpendicular to the supporting surface on which the powered roller is resting, and a motive force parallel to the surface.

A powered pallet truck is provided having a base support portion and a load lift portion. The powered pallet truck has a lift cylinder device connected at a lower portion to a forward extending lift cylinder device seat on the base frame and pivotally connected at an upper portion within a recessed channel in the load lift frame.

This invention presents a high-tech shopping cart designed to revolutionize the retail shopping experience. The cart has four independently controlled wheels, multiple storage compartments, and a controller managing item selection and pricing. Equipped with sensors for obstacle detection, a user-friendly interface, and wireless communication capabilities, the cart offers real-time budget tracking and eliminates the need for traditional checkout queues. Shoppers can interact with the cart via a mobile app, making shopping more convenient and efficient. With autonomous movement and advanced features, this high-tech shopping cart enhances shopping and checkout processes within stores or retail establishments.

A transport device has a carriage and at least three wheels mounted at a minimum of two axles. One of the axles is a driven axle which carries only a single, centrally mounted, electrically driven wheel. A support unit is configured to accommodate an elongated load, such as a golf bag. A guide component on a control side has a handle area. When the cart is in the operational position, the drive axle at the carriage is on hand at the control side, and the support unit substantially protrudes in the direction of the control side laterally across the drive axle.

A patient support apparatus includes a base having a length and including a plurality of caster wheels enabling movement of the patient support apparatus across a floor surface. An auxiliary wheel support structure is secured to the base and rotatably supports at least one non-castered auxiliary wheel about a rotational axis transverse to the length of the base for engagement with the floor surface. The auxiliary wheel support structure may be configured to support the auxiliary wheel and to enable movement of the auxiliary wheel out of engagement with the floor surface to a non-engaged position wherein the at least one auxiliary wheel is out of engagement with the floor surface. A control apparatus is in communication with and moves the at least one auxiliary wheel between at least one deployed position and a non-engaged position.

An electric golf trolley Includes an electric actuator includes a motor controller, two planetary gear reduction motors connected to the motor controller and mounted on two rear wheel modules in a one-to-one correspondence manner, and a power supply connected to the motor controller. A connecting-rod link mechanism is disposed between an upper frame module, a lower frame module and the two rear wheel modules. When folded towards the lower frame module, the upper frame module drives the rear wheel modules through the connecting-rod link mechanism to be folded synchronously. The motor controller is mounted on the upper or lower frame module. The power supply is mounted on the upper or lower frame module. The rear wheel modules are separately driven by the planetary gear reduction motors, so a spindle rotating synchronously along with the rear wheel modules does not need to be additionally disposed between the rear wheel modules.

A weight-bearing device includes a single wheel, a frame attached to the wheel, and an electric motor attached to the frame. The electric motor is configured to rotate a first gear, connected to a second gear with a chain. The second gear is connected to the wheel. The second gear and the first gear may have a gear ratio of greater than 8:1.

A truck includes a body, left and right wheels provided on the body, left and right drive units driving the wheels, a handle provided on the body, a sensor, and a control device. The sensor detects a front-rear load and a moment about a vertical axis applied to the handle. The control device sets a target front-rear velocity of the body based on the front-rear load, and sets a target angular velocity of the body about a vertical axis based on the moment about the vertical axis. In a case where a product of the target front-rear velocity and the target angular velocity is greater than a predetermined threshold, the control device performs correction processing on the target front-rear velocity so that the product is equal to or less than the threshold, and controls the drive units based on the corrected target front-rear velocity and the target angular velocity.
