Cartesian Bridge Systems

Cartesian Bridge Fall Protection Systems

Multiple positioning requirements and lower working heights typically require a rigid rail overhead trolley, or cartesian bridge fall protection system.  Manually and motor driven cartesian, or two way coordinate systems offer the flexibility to provide fall protection for 100% of the planned coverage area.  Cartesian Fall Arrest Systems may be attached to overhead structure for indoor applications such as aircraft hangars or designed and fabricated as freestanding units for outdoor tanker truck applications.  Versatile and easy to use, this form of rigid beam fall protection minimizes fall distance, reduces deflection rates, and is ideally suited for multiple user applications.

Each our systems is the product of an on-site engineering visit where our safety experts watch the interaction of your equipment and personnel to create a custom solution. Our turnkey approach means you can rely on one company to engineer, fabricate, install, and re-certify a custom fall protection solution that provides years of safe and reliable service.  As a sole source provider, we also assume all liability for the system.

Remember, falls are the leading cause of occupational injuries and fatalities each year, and the increased insurance and workman’s compensation premiums combined with the legal fees associated with a fall can have dire consequences.  Ensure OSHA compliance and worker safety with a Cartesian style fall protection system  from the safety experts at Diversified.

We are a complete turnkey provider of OSHA compliant rigid rail fall protection systems and have years of experience designing and installing cartesian  bridge systems.  Contact us for expert assistance with your fall arrest, fall restraint and fall protection requirements.

Design Considerations

Cartesian Fall Protection Design Considerations
As is the case with most fall protection systems, one of the fundamental design considerations for Cartesian Fall Protection systems is size of the planned coverage area.  The system design most not only cover the entire work area, but it must also accommodate the total number of planned users.  it is also important to determine if the system must allow for user pass-by capability.  Once coverage area and user capacity/requirements have been established, multiple bridges may be recommended to provide maximum fall protection for the work area.

Finally, because these systems are suspended overhead, a thorough inspection and assessment of the roof support structure must be undertaken to ensure the building has the structural integrity to support a cartesian fall protection system.  DFP application engineers will perform a site assessment to determine if your roof support system is strong enough to support a cartesian fall protection system.

 

OSHA Regulations

  • Personal Fall Arrest Systems
    • 1926.502(d)
      'Personal fall arrest systems.' Personal fall arrest systems and their use shall comply with the provisions set forth below. Effective January 1, 1998, body belts are not acceptable as part of a personal fall arrest system. Note: The use of a body belt in a positioning device system is acceptable and is regulated under paragraph (e) of this section.
    • 1926.502(d)(16)
      Personal fall arrest systems, when stopping a fall, shall:
    • 1926.502(d)(16)(i)
      limit maximum arresting force on an employee to 900 pounds (4 kN) when used with a body belt;
    • 1926.502(d)(16)(ii)
      limit maximum arresting force on an employee to 1,800 pounds (8 kN) when used with a body harness;
    • 1926.502(d)(16)(iii)
      be rigged such that an employee can neither free fall more than 6 feet (1.8 m), nor contact any lower level;
    • 1926.502(d)(16)(iv)
      bring an employee to a complete stop and limit maximum deceleration distance an employee travels to 3.5 feet (1.07 m); and,
    • 1926.502(d)(16)(v)
      have sufficient strength to withstand twice the potential impact energy of an employee free falling a distance of 6 feet (1.8 m), or the free fall distance permitted by the system, whichever is less.
