A bollard assembly includes a bottom plate with a forward edge and an aft edge, an elongated member mounted on the bottom plate and extending from a forward end to an aft end in a direction from the forward edge toward the aft edge, a bollard secured to the bottom plate with a bollard section of the elongated member disposed inside of the bollard, bars mounted on the bottom plate on opposite sides of the elongated member, and a top plate having a smaller perimeter than the bottom plate mounted on the elongated member and the bars with the bollard extending above the top plate.

A bollard system includes a post extension to extend upward from a floor, a first collar to encircle the post extension, a first connector to encircle the post extension adjacent to the first collar, and a first handrail to be connected to the first connector. The bollard system includes a second connector to encircle the post extension adjacent to the first connector, a second handrail to be connected to the second connector, and a second collar to encircle the post extension adjacent to the second connector. The first collar is invertible selectively to a first lock position and a first release position, the first connector having greater freedom to rotate relative to the first collar when the first collar is in the first release position than when the first collar is in the first lock position.

A bollard apparatus for use as a vehicle barrier includes: a plurality of bollard members; a plurality of separate foot members adapted for ground engagement by placement upon or embedment within a surface, one or more of which is attached to at least one bollard member upstanding therefrom, wherein at least one foot member includes: a front edge; a rear edge; at least one lateral edge which opposes a corresponding lateral edge of a neighbouring foot member, wherein at least one lateral edge extends between the front and rear edges and is non-planar so as to include: a first edge part; and, a second edge part that is laterally offset from the first edge part, wherein the bollard apparatus further includes a coupling assembly which couples the foot member to the neighbouring foot member, wherein the coupling assembly is attached to the lateral edge.

A bollard assembly includes a bollard post, a ground sleeve configured to receive the bollard post, and a stress control device positioned adjacent to the ground sleeve. The stress control device has a face plate and a plurality of support plates secured to a back surface of the face plate. The support plates are angularly space from one another at equal angles and extend radially inward from the back surface towards the ground sleeve such that the ground sleeve fits between the plurality of support plates.

A road barrier transfer machine includes an improved capstan control system that reduces unwanted migration of road barrier spans without requiring inaccurate visual observations and reliance on outdated scripts. The barrier transfer machine includes a moveable chassis, an entry snout, an exit snout, a conveyor system, a capstan system, and the capstan control system. The capstan control system automatically operates the capstan system or provides instructions to an operator of the machine to maintain the tension and compression of a road barrier span within desired ranges to reduce unwanted migration of the span.

A safety trailer is shown including first and second platforms, at least one of said first and second platforms having an axle and wheels attached thereto; a plurality of interconnected wall sections positioned between and connected to the first and second platforms, the plurality of wall sections defining a protected work area on a side of the trailer; and wherein the trailer supports a ballast member, the ballast member being positioned near a first side of the trailer and the wall sections near a second, opposing side of the trailer, the ballast member offsetting, at least partially, a weight of the plurality of wall sections.

A terminal element (100) of a traffic barrier device (1), having a longitudinal axis and comprising a guide element (10) and an impact element (20). The impact element (20) is pivotally mounted on the guide element (10) about an axis (A) which extends parallel to the longitudinal axis (L).

A traffic barrier system of series connectable barriers, each barrier having a body with a skirt section, an intermediate section comprising a lower portion, a central portion, and an upper portion, and a head section extending above the intermediate section. The skirt section and lower portion have positive slopes. The upper portion and head section have negative slopes. A vertical end channel is formed on each of the opposite first and second ends. A lower tension bar is cast in the skirt section and an upper tension bar is cast in the head section. Within the body of the barrier, the tension bars are articulated in relation to each other. The tension bars have tabs extending out of the body for overlapping pivotal connection to an adjacent barrier.
