The invention provides a portable trailer stand, comprising an upper ledge having a longitudinal length extending between a first end and a second end of the upper ledge, an extendable leg coupled to the upper ledge, the leg to selectively extend away from or retract towards the upper ledge, the leg closer to a center of the upper ledge than the leg is to either one of the first or second ends of the upper ledge; and a wheel coupled to the upper ledge, the wheel to remain at a substantially fixed distance from the upper ledge as the leg moves between extended and retracted positions relative to the upper ledge.

A dock shelter or dock seal comprises at least one light fixture (138, 150) disposed along a peripheral edge of the dock seal to help guide a driver in backing a vehicle into the loading dock area, the light fixture (138, 150) includes a generally linearly extending member for conveying and dispersing a light beam; and a light source (144) operatively coupled to the at least one light fixture (138, 150) to project a light beam through the generally linearly extending member.

A retractable bollard system for installation in a support surface that includes pavement includes a shell that when installed in the support surface extends below an upper surface of the pavement. The bollard system includes a post to be telescopically coupled to the shell. The post is axially movable relative to the shell selectively to an upper area and a lower area. The post extends farther above the shell when the post is in the upper area than when the post is in the lower area. The bollard system further includes a shock absorber to encircle the shell. The shock absorber is made of a polymeric material.

Dynamically configurable traffic controllers and methods of using the same are disclosed. An example apparatus includes a first sensor to monitor traffic in a first area; a second sensor to monitor traffic in a second area; a first display panel to: face toward the first area; generate a first signal in response to feedback from the first and second sensors indicating traffic is detected in the second area concurrently with traffic detected in the first area; and generate a second signal in response to the feedback indicating traffic is detected in the second area concurrently with traffic not being detected in the first area; and a second display panel to: face toward the second area; generate the first signal in response to the feedback indicating traffic is detected in the first area concurrently with traffic detected in the second area; and generate the second signal in response to the feedback indicating traffic is detected in the first area concurrently with traffic not being detected in the second area..

Motion sensing dock lighting systems are disclosed. An example lighting system for use at a loading dock where a material handling device is used to load or unload a vehicle parked at the loading dock includes a motion sensing system to be spaced apart from the material handling device. The motion sensing system is to provide an operation signal in response to the material handling device undergoing a change in travel direction within the vehicle. The example lighting system also includes a lamp to be operatively connected in signal communication with the motion sensing system so as to receive the operation signal from the motion sensing system. The lamp is to have a first illuminating mode and a second illuminating mode, and the lamp is to switch between the first illuminating mode and the second illuminating mode in response to the operation signal.
