Maneuverable ergonomic trailer stands are disclosed. An example portable trailer stand includes: a frame having an upper ledge, a post, and a lower subframe, the lower subframe connected to the upper ledge via the post; an extendible leg coupled to the post independent of the lower subframe, the upper ledge being vertically movable based on movement of the extendible leg relative to the upper ledge, the post, and the lower subframe of the frame; and a wheel connected to the frame via the lower subframe such that the wheel is to move with the upper ledge as the upper ledge is vertically moved.

A method to adjust the height of a display is provided. One terminal of the telescopic trolley is connected to a first surface of the display and is separated from the lower edge of the display by a first distance. The lower edge of the display is away from the ground by a second distance. The method includes: obtaining a first height value indicating a user's height, an eye height or a shoulder height, searching for a second height value corresponding to the first height value in the look-up table according to the first height value, calculating the sum of the first distance and the second distance, comparing the sum with the second height value to obtain a comparison result, and adjusting the length of the telescopic trolley according to the comparison result, so that the sum is equal to the second height value.

A wheel/foot assembly for a sign display stand or other object includes a cradle partially enclosing an optional wheel. The assembly is releasably attachable to a leg for a sign display stand, protects the leg and can be easily replaced if worn. The assembly protects wear on the stand and permits the sign display stand to be wheeled, rather than dragged or carried. Because the assembly is releasably attached, it can be replaced easily if damaged or worn.

A cart for medical equipment includes a column supporting a platform for mounting a piece of medical equipment to the cart. A base including one or more wheels that support the column, and a handgrip at least partially encircling the platform. The handgrip includes an upper surface substantially devoid of openings and an opposite lower surface including one or more elongated accessory slots opening downwardly toward the one or more wheels. The one or more elongated accessory slots are configured to receive a portion of an accessory mount such that the accessory mount is slidingly adjustable along a length of the one or more accessory slots.

Disclosed herein is a rotational roller apparatus for use with a pipeline unit. The pipeline unit is received in a pipeline for welding and/or inspection. The rotational roller is attached to and is able to support at least a portion of the weight of the pipeline unit. The rotational roller unit also includes an extension member and a reduced friction base. The reduced friction base is attached to an end of the extension member so that the rotational roller has a retracted and an extended configuration. In the extended configuration, the reduced friction base contacts an interior of the pipeline and supports at least a portion of the weight of the pipeline unit and thereby allows the unit to be rotated about a longitudinal axis within the pipeline.

Sign display stands include legs. A leg for a sign display stand includes: a first side; a second side; a base; an inner surface defined by the first side, the second side and the base; an outer surface defined by the first side, the second side and the base, the outer surface opposite the inner surface; a channel defined at or about at least one of the first side and second side on the inner surface, the channel configured to receive a sign panel; and at least one protuberance positioned on the inner surface and substantially along a longitudinal axis of the leg.

An apparatus and method transfer a shipping container from a first dockside unloaded position to a second transporting position. A horse-and-saddle assembly is mounted on a pair of transversely spaced rails, and includes a horse member with roller mechanisms cooperating with the rails. A saddle member includes a mounting frame capable of moving transversely upon the horse member. The saddle member is configured to carry the shipping container mounted thereon. A carrier suspended from an overhead monorail is movable along a track extending from the monorail. Once deposited in the saddle member mounting frame, the shipping container in the mounting frame is urged to a position from which lifting devices mounted onto the saddle frame raises the shipping container from the mounting frame. The shipping container is carried while suspended from the overhead monorail carrier to a desired transfer or storage location.
