A base for a guardrail includes a base body including a receptacle for receiving and securing a part of a railing and one or more wheels coupled to the base body. The one or more wheels are configured for transportation of the base.

A warning structure includes a bracket and a warning member mounted on the bracket. The bracket includes a main body, rollers rotationally mounted to the main body, and a stopping assembly including a support member, a mounting member, and a resilient member. The support member is coupled to the main body. The mounting member is movably mounted to the support member. The rollers are mounted to the mounting member and the main body. The resilient member elastically resists the support member and the mounting member to bias the mounting member. When the support member is subjected to a downward force, the support member abuts against a ground to keep the bracket stationary.

Disclosed is a concrete block, preferably made of fiber-reinforced concrete, including a body and anchor intended for lifting the block. The anchor is secured to the body and arranged in blind cavities without protruding out of these cavities, particularly arranged at the level of one of the faces of the body of the block such as the upper face of the block when the block is in the installed position on the ground. The body includes reservations and/or attachment/association components, the reservations and the attachment/association component being intended for attaching, preferably removably, or associating, technical equipment that is to be associated with the block. The concrete block is intended to constitute an access-denial bollard and, as a secondary function, a block for supporting and to which to fix technical equipment.

A weighted unit is provided. The weighted unit includes an enclosed shape, the shape having horizontal channels running along the entire base of the unit from one side to an opposing side, such that the horizontal channel is open to each opposing side, the weighted unit being placed over a horizontal and/or vertical member of an object to be held down with the channel engaging the horizontal member to hold the object in place. Protrusions or other features are integrally formed in the weighted unit to allow the weighted unit to hang from the object to be weighed down without the weighted unit touching the ground. The weighted unit may be placed directly over the top of a horizontal member of the object to be weighed down without also engaging, or being placed around, a vertical component of the same object.

Temporary barrier fencing has at least one fence panel having a bracing post at one end which engages a support foot and which comprises a brace which braces an adjacent post and a locking post at an opposite end which keys the foot depending on the orientation of the panel with respect to the foot thereby being intrinsically secure against forced entry.

An apparatus for dispensing cones onto a surface and for retrieving cones from the surface includes a cone transfer device having a tower with a platform moveable to and from a lower transfer position for dispensing cones onto the surface and for retrieving cones from the surface. The platform is movable in a vertical direction between the lower transfer position and an upper transfer position for receiving a stack of cones from a storage area and for returning a stack of cones to the storage area. The tower includes a device for holding one or more cones in an elevated position and for releasing cones onto and receiving cones from the platform in the elevated position. The apparatus may include a lamp transfer device for attaching a lamp unit to a cone when the cone is dispensed and for removing the lamp unit from the cone when the cone is retrieved. The apparatus may include a cone washing device for washing a cone when the cone is retrieved and/or when the cone is dispensed.
