A material transport cart includes a cart body, a material support body coupled to the cart body, a wheel coupled to the cart body, a motor operable to drive the wheel, and a powered lift assembly. The powered lift assembly is coupled to the cart body and to the material support body. The powered lift assembly is operable to lift the material support body relative to the cart body. A removable battery is electrically coupled to and operable to supply power to both the motor and the powered lift assembly.

The system can include: a container 110, a set of sensors 120, and a controller 130. The system can optionally include a robot 140. However, the system 100 can additionally or alternatively include any other suitable set of components. The system functions to monitor and/or maintain a fullness level of a container. The system can additionally or alternatively function to enable robotic picking out of the container (e.g., in a pick-and-place setting). The system can additionally function to maintain candidate objects within reach of the robot's end effector to increase robot uptime while minimizing the extent of the robot's required motion (e.g., in the z-axis).

A hydraulic control system for linear actuation that includes an electric motor connected to a hydraulic pump and a hydraulic cylinder connected to the pump by a first flow line. A pressure transducer, a pressure control valve, and a check valve are connected to the first flow line between the pump and the cylinder and a tank is connected to the pump by a second flow line and the cylinder by a return line. A control valve is connected between the first flow line and the return line.

Embodiments of the inventive subject matter are directed to vertically stabilized platforms. These platforms have a top portion that moves only along a single axis (e.g., vertically up and down), and a bottom portion that remains stationary relative to a reference frame. The top portion is coupled with the bottom portion by scissor linkages that are all configured to slide on one end to allow the top portion to move up and down without any perturbations or movements along any other axes. Stabilization in some embodiments is accomplished by incorporating struts that couple with both the bottom portion (either directly or indirectly) and two of the scissor linkages. Struts can include both a damper and a spring and can be selected based on anticipated load to be stabilized. Embodiments can be mounted on, e.g., truck beds, ships, or other surfaces that can move, giving rise to a need for a stabilized platform.

A device for lifting and stabilizing loads includes a frame and a cross-beam arranged below the frame, wherein the device receives the load and, via lifting structure fastened to the cross-beam, is adjustable for height and can be stabilized via two crossing telescopic struts, where one internal tube and one external tube are interconnected, connection of the telescopic struts is established via three form-fitting traction parts, one first form-fitting traction part in the internal tube of a telescopic strut is mounted at both ends via respective inner and outer disks, a third form-fitting traction part is mounted on two rotatable disks, the disks of the respective first and third traction parts situated on one side are interconnected such that rotational movements between both disks are transmittable, and where the respective first form-fitting traction part is fastened on the inner wall of the two external tubes.

The present disclosure provides an end-to-end cargo handling system. The end-to-end cargo handling system comprises a transportation unit comprising a first sensing agent, a lift unit comprising a second sensing agent, and a control module in communication with the transportation unit and the lift unit via a network, wherein the transportation unit and the lift unit are configured to move a cargo unit from a first location to a second location autonomously.

A pantograph-type lifting system comprises a base; a platform connected to the base by a pair of levers each comprising a first lever and a second lever mutually hinged in a fulcrum, the first lever having a lower end hinged to the base, and an upper end sliding connected to the platform, the second lever having a lower end sliding connected to the base, and an upper end hinged to the platform in a fixed spot; a chain-type actuating system of the levers comprising one chain meshed with a first toothed pulley and with a second toothed pulley rotatable connected to the respective levers, the chain-type actuating system being configured to transfer the motion from motor means to the levers through the toothed pulleys in order to approach or move away the ends of the levers with a scissors-like movement to lift or lower the platform.

Each scissor frame of the patient positioning table has a first and a second scissor arm connected in an X-shaped arrangement to pivot about a common pivot axis via a lifting facility for vertically moving the positioning table. The lifting facility includes a roller arrangement configured to be moved by a traction device. The roller arrangement is arranged between, and guides, arm segments of the scissor frames. The arm segments open in a V-shape, wherein the traction device is fixed in position by at least one end and is led via a roller unit having deflecting rollers, one located upstream of the roller arrangement and one located downstream of the roller arrangement. The position of the roller arrangement between the arm segments is variable with the aid of a drive facility, which interacts with the traction device.

A vehicle lift system includes a vehicle lift operable to lift a vehicle to be serviced by a technician. The vehicle lift includes lifting components for engaging and lifting the vehicle at liftable structures of the vehicle. Electrodes are positioned on the lifting components of the vehicle lift. The electrodes are operable to make electrical contact with the liftable structures of the vehicle when the lifting components engage the liftable structures. A voltage detector system is in electrical communication with the electrodes. The voltage detector system is operable to detect voltages at the electrodes capable of harming the technician. The voltage detector system is also operable to send a warning signal to the technician indicating that a harmful voltage has been detected on the electrodes when the electrodes make electrical contact with the liftable structures of the vehicle.

A lift for elevating an object having a base including two legs, lifting apparatus associated with each leg, vertically telescoping guard elements extending along each leg, the lifting apparatus being arranged to lift an object disposed above a plane between said legs, the guard elements telescoping vertically when the lifting apparatus is deployed to exclude a person's limb from a space above said planes.
