ABSTRACT:
A trailer crash attenuation assembly includes a longitudinal hollow member adapted to act as a hydraulic cylinder at one end, hydraulic fluid disposed in the hydraulic cylinder and a tank connected to the hydraulic cylinder to receive and store said hydraulic fluid expressed from the hydraulic cylinder. A first longitudinal telescopic member is adapted to slide into and out of the longitudinal hollow member and is adapted to act a piston. Two other longitudinal hollow members are positioned substantially parallel to and on either side of the first longitudinal hollow member and are connected to the first longitudinal hollow member. Two telescopic members are adapted to slide into and out of the two other longitudinal hollow members respectively. A casing is connected at its proximal end to all three longitudinal hollow members, is adapted at its distal end to receive a crash cushion; and has a pair of wheels.
