摘要： A ladder tie off system incorporates a safety strap into a ladder for securing the ladder to prevent undesired tipping. The system includes a ladder having a pair of lateral side members and a plurality of rungs extending between the lateral side members. A extendable tether includes a tensioning mechanism, a fixed section, and an extendable section. A mount is coupled to the tensioning mechanism of the extendable tether. The mount is coupled to the ladder proximate a top end of the ladder wherein the extendable tether is configured for is secured to a static object near the top of the ladder whereby the ladder is inhibited from tipping during use.

摘要： A support tower is equipped with a plurality of step-bolts, each of which comprises (1) a threaded portion that is attached to a pre-existing hole in the tower and (2) a shaft portion that extends outward from the tower. The shaft portion of each of the step-bolts includes an undercut section that is sized to match (with minimal clearance) the throat of a corresponding carabiner, which is attached to a safety harness worn by the user. The remainder of the shaft portion of the step-bolt is larger in diameter than the throat of the carabiner so that the carabiner cannot slide out toward the free end of the step-bolt.

摘要： An anti-ram system and method of construction having a shallow mounted base pad from which extend a plurality of bollards. Very little or only a shallow excavation is required for the base of the bollard system, which can be partially or fully assembled prior to bringing it to the installation site. The shallow mounting pad or base of the bollard system of this invention may be formed or constructed in various ways and of various materials, and in various configurations. The shallow mounting pad or base is constructed so as to have considerable mass.
