The safety tripod includes a tripod, a flight driving machine mounted on the tripod to enable the tripod to fly, a landing base for seating the tripod on the ground when the tripod lands, and a standing guide mounted on the tripod to enable the tripod to stand up.

The warning flag stand is the only product of its kind that stands at a high height on the road and comes in a set of six to fully define the area of an emergency setting. The warning flag stand is uniquely designed with indestructible and durable materials to ensure long-term sustainability. Moreover, the warning flag stand is carefully crafted with a double-sided reflective foldable triangle and mesh supporting system to guarantee the sign is visible from far distances, angles and terrains.

A collapsible user customizable sign having a frame on a first end of a pole where the frame is moveable between a collapsed position to a deployed position. The frame has a plurality of removably engageable flexible panels having indicia thereon connected to distal ends of aligned horizontal members of the frame. The flexible panels may be changed to change the indicia and or the color of the flexible panels to provide a user a customizable portable sign.

There is provided a structure support arrangement for supporting a structure, the structure support arrangement comprising: a body member; a nesting formation defined on the body member and configured to prevent lateral movement of the structure support arrangement in at least one transverse direction when the structure support arrangement is nested with a further structure support arrangement; and a post receiving formation defined on the body member and configured for receiving a support post to support the structure.

A barrier system is used to direct and block a travel path of pedestrians and vehicles. The barriers may be shaped substantially as a truncated pyramid with a base surface and planar sides extending from the edges of the base surface to a top portion, where the cross-sectional area of the base surface is larger than the cross-sectional area of the top portion. The angles of inclination between the planar sides and the interior of the base surface are acute angles. The bollard can be cast from heavy dense materials. The bollard includes at least two overhanging lips on the planar sides of the barrier between the base surface and the top portion. The configurations of the bollards provide improved placement, such as with cranes, hand carts, and other devices. Molds to cast the barriers and hand carts to move the barriers are also disclosed.
