A shaped barrier comprises a substantially horizontal portion, a ramp portion, a substantially vertical portion, and at least one connector. The substantially horizontal portion is configured to increase the stabilizing force between the shaped barrier and the ground in an effective amount to prevent substantial movement of the shaped barrier by distributing at least a portion of a groundward force of a rolling vehicle on a receiving side of the shaped barrier. The ramp portion is configured to receive the rolling vehicle onto the horizontal portion. The substantially vertical portion is configured to impede the movement of the rolling vehicle. The at least one connector is configured to connect the shaped barrier with at least one other shaped barrier.

A shallow mount safety bollard assembly includes a bottom plate having a front edge, an aft edge, and a longitudinal axis extending in a front-to-aft direction and a lateral axis perpendicular to the longitudinal axis, a pair of side bars, having front ends and aft ends, attached to a top plate surface of the bottom plate and extending generally parallel to the longitudinal axis, a sleeve having a bottom end attached to the top plate surface between the pair of side bars, an internal bore, and a top opening, a bollard having a lower section located in the internal bore, and a latch moveable from a lock position fixedly securing the bollard to the sleeve and an unlock position allowing the bollard to be removed from the sleeve.

The present subject matter provides a gate for controlling passage of vehicles including: at least one first blocking element configured to swivel about a first pivot axis; and at least one second blocking element configured to swivel about a second pivot axis, wherein the first blocking element and the second blocking element are configured to swivel one opposite the other in a manner that a gap is formed between the first blocking element and the second blocking element, wherein the gap is set to allow or block passage of vehicles through the gap. Additional embodiments of the gate are disclosed herein.

A damper device comprises a cylinder, a piston bearing on one side of the cylinder, a piston rod displaceably received by the piston bearing, and a bottom unit on another side of the cylinder. The cylinder, the piston bearing and the bottom unit form a closed chamber that is filled with a compressible liquid. The piston rod subdivides the chamber into first and second chamber halves between which the liquid can be displaced if the piston rod is displaced relative to the cylinder. Furthermore, the closed chamber provides for a variable volume so as to compensate temperature-induced pressure fluctuations inside the closed chamber.

A barrier system including an elastic net coupled to a cable, an energy absorption member coupled between the cable and an anchoring assembly, and an actuation assembly coupled to the net and configured to rotate the net about an axis of rotation between a closed position restricting vehicle access through the barrier system, and an open position allowing vehicle access through the barrier system.

A multiple direction railroad gate release mechanism which is attached between the mount arms of a railroad gate actuator and a crossing arm to prevent breakage of the crossing arm due to impingement in either a frontal or rearward direction by a vehicle or other outside force. A primary pivot arm assembly allows a released movement of the crossing arm in reaction to frontal impingement and returns the crossing arm to the original and detent position subsequent to an impingement in order to maintain grade crossing protection. Spring assemblies, a shock absorber and a spring centering assembly act to return the primary pivot arm assembly and attached crossing arm to a normal detent position. A secondary pivot arm assembly is secured to the primary pivot arm assembly whereby the secondary pivot arm assembly can act independently of the primary pivot arm assembly to allow released movement and return of the crossing arm in reaction to rear impingement.

A barrier includes recycled rubber portions molded around a core infrastructure. The core infrastructure may itself include recycled rubber in a containment body. The containment body may include baled recycled or other waste material. The barriers may be stacked or connected to form a barrier structure useful in environmental control and other applications. The method for making the barriers includes molding rubber portions and a binder around a core infrastructure.

In one embodiment, a bollard system includes multiple support beams adapted to be embedded in concrete, multiple bollards, each bollard being attached to a support beam a point near a center of the beam, and a reinforcing bar that is woven between the support beams to provide reinforcement to the system.

A pedestrian barrier system includes first and second barriers each having first and second sides, first and second ends, and an upper hand guide positioned along the first side. The first end of the first barrier is pivotally connected to the second end of the second barrier, wherein the first and second barriers are pivotable between at least a linear configuration wherein the first sides of the first and second barriers are co-planar and an orthogonal configuration wherein the first sides of the first and second barriers are perpendicular, and wherein the upper hand guide of the first and second barriers are continuous when the first and second barriers are in the linear and orthogonal configurations.
