A mobile, stationary and/or temporary barrier (9) having mobile obstacles for the protection of crowds. The temporary barrier (9) includes a plurality of mobile obstacles (1). The mobile obstacles (1) are self-propelled and each include an extendible carriage and a drive. Connection elements are provided for connecting the mobile obstacles (1) to one another, and the connection elements (5) are elastic in order to absorb kinetic energy.

An anchorless crash cushion apparatus comprises a number of crash cushion elements and a number of hinge plate assemblies. The crash cushion elements are configured to be connected end-to-end. Each hinge plate assembly comprises a forward structure, a rearward structure, and a wedge incline. The forward structure supports the front end of one of the crash cushion elements. The rearward structure supports the rear end of the crash cushion element. The wedge incline extends diagonally upward toward the forward structure and is configured to drive a subsequent one of the crash cushion elements upward when the forward structure is driven toward the subsequent one of the crash cushion elements.

A crash impact attenuator is adapted for deployment on a vehicle, and includes a cartridge portion having at least one energy absorbing module, as well as a backup system having a backup frame, which is adapted to attach the cartridge portion to the vehicle. The backup system includes an actuator configured to pivot the cartridge portion between a deployed orientation and a stored orientation about a pivot axis disposed on a lower half of the backup system. The backup system further includes a lockout frame member having a contact surface on one end thereof, the lockout frame member being actuatable between a deployed orientation wherein the contact surface engages a portion of the backup frame to support the backup frame against vehicular impact forces and a stowed orientation wherein the contact surface is not engaged with the backup frame.

A towable crash-attenuating vehicle is shown having a frame; at least two axles coupled to the frame, each of the axles having wheels attached thereto; a ballast coupled to the frame; deflection shields coupled to the right and left sides of the frame, wherein the deflection shields cover the frame and a majority of the wheels on each side of the vehicle; a tow connection coupled to the front of the frame; an impact attenuator coupled to the rear of the frame; wherein the vehicle is provided with a brake system, and wherein the vehicle is provided with an mechanism for locking and unlocking the brake system.

An anchoring apparatus for an irrigation system is disclosed. The anchoring apparatus includes a support base for securing to an axle of a support tower of the irrigation system. A threaded sleeve is secured to the support base and holds a shaft. The shaft has a threaded portion and an anchor portion. A motor secured to the support base is configured to rotate the shaft in a first direction about a longitudinal axis of the shaft to move the shaft along the longitudinal axis towards an anchoring position to secure and protect the system against wind and severe weather. The motor is also configured to rotate the shaft in a second direction about the longitudinal axis of the shaft to move the shaft along the longitudinal axis towards a disengaging position to lift the anchor portion of the shaft off of the ground.

A mobile barrier is shown having first and second platforms, at least one of the first and second platforms engaged with an axle and a set of wheels; a safety wall assembly, having a mechanism for translation of the safety wall from one side of the platforms to another, the safety wall further having telescoping first and second portions allowing the safety wall assembly to expand and retract in length along the longitudinal axis of the mobile barrier; a plurality of variable length braces connected to the platforms and the safety wall, which expand and retract as the safety wall moves from one side of the platforms to the other.

An impact-attenuating device includes a first energy-absorbing part having at least one first elongate body and at least one corresponding first energy converter to deform the first elongate body in the case of relative movement. A second energy-absorbing part has at least one second elongate body and at least one corresponding second energy converter configured to deform the second elongate body in the case of relative movement. A bumper is coupled to the first energy-absorbing part. The first and second energy-absorbing parts are positionable one behind the other. The first and second energy-absorbing part are mutually coupled such that the at least first and second elongate bodies are deformed at least partially simultaneously by respectively the at least one corresponding first energy converter and the at least one corresponding second energy converter when a vehicle crashes into the bumper.

The present invention is directed to differing embodiments of safety trailers, which have first and second platforms and a safety wall positioned therebetween. The platforms and safety wall define an area protected from vehicular incursions.

An impact attenuator including an impact head, coupled to a first end of an energy absorption body, which energy absorption body is arranged for fixation to an external structure at a second end opposing the first end of the energy absorption body, configured to at least partly absorb or dissipate energy from a collision of an object with the impact head, and including a first part and a second part extending substantially lengthwise behind each other, wherein the first and second part are mutually moveable and including a first and a second cutting edge, wherein, the first cutting edge is arranged for splitting the first part of the energy absorption body upon impact of an object colliding with the impact head, and the second cutting edge is arranged for consecutively splitting the second part of the energy absorption body upon impact of an object colliding with the impact head.

A safety system is shown including a vehicle, first and second platforms, a barrier positioned between and connected to the first and second platforms defining a protected work area on a side of the trailer; a detachable caboose and wherein the vehicle and caboose are engaged with the first and second platforms, and the vehicle and caboose have braking systems that operate independently.
