Horizontal lifeline traversing device

In a load attachment system including an elongated substantially horizontal line secured at its ends to a structure and supported at least one intermediate point by a support member secured to said structure and a load attachment traversing device engaging said line for movement therealong, said device traversing said support member without detachment from said line, the improvement comprising:

• said support member including a bar extending from said structure to provide vertical support for the line, said bar including a retaining member at a forward portion of the bar for preventing radial movement of said line;
• said load attachment traversing device including a grooved roller engaging the upper surface of said line for rolling movement along the length thereof;
• said load attachment traversing device further including an open center and an upper arm supporting said roller, said device further having a substantially vertical portion extending downwardly below the level of said line and including a lower arm extending forwardly beneath said line;
• means carried by said lower arm for securing a load to said device, and
• means carried by said lower arm for preventing said device from vertical movement so that the same cannot be removed from said line.
