    摘要: A beam anchor. The beam anchor is generally used for attaching to a flanged beam that has been made a part of a structure, to provide fall protection for a worker working on the structure. The beam anchor includes a main cross-member with a beam capturing member at each end. One or both of the capturing members have associated therewith respective yaw restoring mechanisms providing a combined restoring torque for urging the cross-member in counteraction to twisting thereof by a yaw angle in a yaw plane that is substantially parallel to the surface portions. Preferably, a lanyard attachment member is slidably disposed on the cross-member and spring-biased into a relatively centered position between the capturing members.

    摘要: An expansion bolt. A first chock has first and second outer ramping surfaces. A second chock has an inner ramping surface complementarily corresponding to the first outer ramping surface. A spring member biases the second chock radially inwardly against the first outer ramping surface of the first chock.
