A safety trailer 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 each wall section has first and second end members, each of the first and second end members comprising an outwardly projecting alignment member and an alignment-receiving member, the first and second end members having the alignment and alignment-receiving members positioned in opposing configurations.

The invention relates to a lane delimitation arrangement (1) comprising at least a first stationary lane delimitation element (2) and a movable lane delimitation element (4) which is movable relative to the first stationary lane delimitation element (2). The movable lane delimiting element (4) comprises a first end (12) and a second end (13), the second end (13) preferably comprising a hinge device (15) and the first end (12) comprising a locking element (5). The first stationary lane delimitation element (2) comprises a locking arrangement (14) complementary to the locking element (5), wherein the movable lane delimitation element (4) has a first position in which the first stationary (2) and the movable lane delimitation element (4) are not coupled together and a second position in which the first stationary (2) and the movable lane delimitation element (4) are coupled together. In the second position, the locking element (5) of the movable lane delimitation element (4) engages the locking arrangement (14) of the first stationary lane delimitation element (2), wherein the movement of the movable lane delimitation element (4) from the first to the second position is a pivoting movement. The locking element (5) has a lateral recess (6) for the locking arrangement (14) of the first stationary lane delimitation element (2) or the locking arrangement (14) of the first stationary lane delimitation element (2) has a lateral recess (6) for the locking element (5).

A traffic barrier lifter mountable on a boom and having a gearbox with a first and a second rotating axis; a pair of opposing arms directly mounted to the first and second rotating axis and a rotator capable of rotating the lifter relative to the boom, wherein the gearbox is capable of moving the pair of opposing arms from an open position to a closed position such that the arms can clamp onto a traffic barrier. The rotator being capable of rotating the arms and traffic barrier relative to the boom.

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.

A barrier system includes a plurality of barriers that can be used to form a barrier wall. Each barrier includes a first panel at least partially bounding a cavity and a first leg assembly supporting the first panel in an elevated position. A plurality of spikes are removably disposed on the first panel. A flexible snare is disposed within the cavity of the first panel, the snare being secured to the plurality of spikes so that when the spikes are removed from the first panel, the snare is drawn away from the first panel by the spikes.

A traffic barrier lifter mountable on a boom and having a gearbox with a first and a second rotating axis; a pair of opposing arms directly mounted to the first and second rotating axis and a rotator capable of rotating the lifter relative to the boom, wherein the gearbox is capable of moving the pair of opposing arms from an open position to a closed position such that the arms can clamp onto a traffic barrier. The rotator being capable of rotating the arms and traffic barrier relative to the boom.

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.

A telematics device for a barrier transfer machine with machine sensors that capture operational data of the barrier transfer machine associated with a barrier segment includes a processing element, a communication element, and a memory element. The processing element is configured to receive the captured operational data. The communication element is in communication with the processing element and is configured to wirelessly transmit a signal representative of at least a portion of the captured operational data. The memory element is in communication with the processing element and is configured to store at least a portion of the captured operational data.
