A portable power source is moveable over a support surface. The portable power source has a power supply, a frame at least partially surrounding the power supply, at least one wheel, handle having a user engagement member a and a clamping mechanism. The clamping mechanism moves from a first position to a second position. The clamping mechanism stops the wheel in the first position and allows the rotation of the wheel in the second position.

A mobile storage device that includes one or more coupling mechanisms. The mobile storage device includes one or more wheels coupled to one or more housings. The mobile storage device can be used on construction sites to help workers move and hold tools, equipment, and other material. The one or more coupling mechanisms are configured to engage with storage units, such as storage units within a modular system.

A galley cart assembly that includes a cart and a wheel assembly attached to the cart. The wheel assembly includes a plurality of wheels and a drive assembly configured to drive one or more of the plurality of wheels to propel the cart. The wheel assembly also includes a primary brake assembly to lock one or more of the plurality of wheels to prevent movement of the cart. Furthermore, the galley cart assembly includes a controller coupled to the cart and including a processor and a memory. The controller includes a turbulence monitoring system configured to detect a turbulence event. The controller is in communication with the wheel assembly, and is configured to automatically operate the primary brake assembly to lock the cart in position when the turbulence monitoring system detects the turbulence event. In certain configurations, an aircraft includes the galley cart assembly.

A vehicle mitigation system a barrier hauler and at least one barrier. The barrier hauler includes a stem, a handle positioned at one end of the stem, and at least one wheel positioned near an opposite end of the stem, the wheel capable of rotating relative to the stem. The barrier hauler further includes a lift arm having an engagement pin, the lift arm rigidly fixed relative to the stem and disposed at a first angle to the stem. The barrier includes at least one wheel positioned at a first end of the barrier to act in cooperation with the at least one wheel of the barrier hauler when the barrier hauler is engaged with the barrier.

In this moving body, a walking assist device (1) is provided with: a plurality of drive wheels (50) capable of rotating about a plurality of rotational axes (51) disposed on a circumference centered on the same axis line (C); and a huh case (60) for supporting the plurality of rotational axes (51) so as to be able to revolve around the axis line (C). A first motor (10) is connected to the plurality of drive wheels (50) in a power transmissible manner so as to allow the plurality of drive wheels (50) to rotate, and a second motor (20) is connected to the huh case (60) in a power transmissible manner so as to allow the plurality of drive wheels (50) to revolve.
