An improved auto-chocking enabled cargo dolly that is towable by ground support equipment. The dolly has a frame, wheels attached to the frame that support the frame and rotate to allow movement of the frame, a tow bar, a linkage in communication with the tow bar and that actuates when the tow bar is raised, and a wheel engagement chocking system fixed to the dolly frame and disposed to selectively engage at least one of the wheels attached to the dolly frame. The wheel engagement system is responsive to a position of the linkage, where the wheel engagement chocking system applies pressure directly to at least one of the wheels to hold the wheel(s) in place when the linkage is actuated by the tow bar.

The trailer-mounted three-way adjustable wheel locking device disclosed herein may be reversibly mounted on a trailer deck, and may allow for the quick securing of a lawn mower, all-terrain vehicle, or other similar vehicle to the deck. The device may comprise two chocks into which one wheel of the vehicle may be driven or pushed, and a locking arm that secures the wheel of the vehicle between the two chocks. The locking arm itself may be reversibly locked for safety and security. The trailer-mounted three-way adjustable wheel locking device may further comprise a height, width, and length adjustment mechanism that allows for tires of different heights, widths, and diameters to be secured.

An automated order fulfillment facility including one or more rows of storage locations for storing totes or other containers, mobile robots configured to move along and/or between rails to transfer the totes or other containers to and from the storage locations, and an energy absorbing mechanical guard mounted at a point along the rails to block or stop a runaway mobile robot. The energy absorbing mechanical guard may be configured to stop mobile robots traveling at a maximum rate of speed for the mobile robots, without damaging the mobile robots.

An integrated vehicle jacking assembly includes a plurality of jacks that is each coupled to a bottom side of a vehicle. Each of the jacks is actuatable into an extended position for lifting a respective driver's side or passenger's side of the vehicle upwardly thereby facilitating tires on the respective driver's side or passenger's side of the vehicle to be removed and replaced. A control unit is positioned within the vehicle and the control unit is operationally coupled to each of the jacks. The control unit actuates one or both of the jacks between the extended position and the retracted position. A plurality of wheel chocks is provided for inhibiting the vehicle from rolling when the vehicle is lifted.
