(54) Vehicle barricade
(57) A vehicle barricade including a barrier plate which can be raised or lowered and a counterweighted sector mounted near the side of the barrier plate. The counterweight is mounted on the sector so that the barrier plate will remain in the raised or lowered position without independent mechanical aid. The barricade is so constructed and secured that it is able to withstand impact from either heavy or light vehicles. The barricade may also be reenforced by placing auxiliary pillars adjacent to the barrier plate and which pillars cooperate with the barrier plate to further secure it when raised.
