Abstract
A barrier system comprises a housing, substantially vertical members, and vertical guide tubes. The housing extends into the ground. The guide tubes are positioned in the housing and also extend into the ground below the housing. The substantially vertical members are translatable vertically within the guide tubes. At least one barrier member is secured to the substantially vertical members. The at least one barrier member may comprise at least one guardrail, a plurality of chains or cables, and/or a plurality of gate beams. A series of cables and pulleys form an actuation system that raises and lowers the substantially vertical members relative to the guide tubes to selectively extend and retract the at least one barrier member relative to the ground. A cover plate may selectively cover the top opening of the housing when the barrier member and substantially vertical members are retracted within the housing.
