This specification should be modified to suit a specific project. This specification does not include the design and installation of davits, outrigger beams, and horizontal cable or monorail systems.

Summit Anchor Company specializes in fall protection and suspended maintenance equipment:

* Installation of roof anchors and horizontal cable systems
* Fabrication and supply
* Testing and certification of suspended access equipment
* Consultation
* Design and engineering

We provide a single source contact from meticulous planning of a roof anchor layout to expert installation of the system. Summit Anchor takes great care to ensure that the highest level of safety is met every step of the way. All summit Anchor Co. products and installations are OSHA compliant and cost effective. Since each building is unique, we develop customized solutions by carefully examining that building's maintenance needs. This initial consultation and preliminary design service is offered free of charge.

Summit Anchor Company Roof and Wall Anchors:
Our anchor eyes are drop forged, resulting in a stronger anchor than the common U-bar type anchors. According to the Forging Industry Association, forgings have grain oriented to shape for greater strength. Machining bar and plate may be susceptible to fatigue and stress corrosion because machining cuts material grain pattern. In most cases, forging yields a grain structure oriented to the part, resulting in optimum strength, ductility and resistance to impact and fatigue.

Summit Anchor Company Specialty Access Equipment:
Horizontal Cable Systems are permanently installed and are used for fall arrest and fall restraint. They safely allow up to two workers continuous horizontal movement across spans of 150 feet or more. Horizontal cable lifelines are ideal for working and walking surfaces where a 42-inch guardrail or parapet is not present. All exposed components are hot-dipped galvanized or stainless steel.

Summit Anchor Company Rigging Sleeves:
Rigging sleeves solve many access problems encountered by building designers, who want to provide safe access for the maintenance contractor. Rigging sleeves are engineered to gain access through building features such as overhangs, skylights, and rotunda ceilings. Rigging sleeves accomplish this by providing a passageway for rigging suspension lines and may be installed through terraces, roofs, floors, walls and overhangs. The advantage of rigging sleeves is they allow the maintenance contractor access to areas that would otherwise be inaccessible.

Summit Anchor Company Monorail:
Monorail Systems incorporate a track that typically runs along the facade of the building. Monorail can be used for the following:
* Large overhangs
* Atriums
* Interior curtain wall surfaces
* Suspension of gantries

Summit Anchor Company Roofcars:
Roofcars are permanently designated to the interior or exterior of a building. Electrically driven roof cars have controls located inside the platform which allow the operator to perform tasks as follows:
* 1. Ascend
* 2. Descend
* 3. Drive
* 4. Swivel
* 5. Tilt
A two-person aluminum platform is tethered with cables to the roof car boom. Typically, a roof car assembly is self contained and does not require maintenance contractors to bring additional suspension equipment to the roof. A roofcar may run on two double-laid tracks on the roof or parapet that follow the contour of the building. A roofcar may also run on four wheels with a guiding track. Roofcars may be equipped with long boom spans. These booms can be designed to clear terraces or lower roofs eliminating the need for additional suspension equipment.

Summit Anchor Company Davits:
Davits are typically used in pairs to support swing stage operations. Davits may also be used singly when supporting one-man rope descents or one-man cages. Davits are often used to clear components of a building (such as parapets, cornices, overhangs or sloped glazing) that are not designed to bear sufficient loads for suspended maintenance.

Summit Anchor Company Testing and Certification:
Our policy here at Summit Anchor Company is to randomly test our anchors in the shop to ensure proper load bearing. These test reports are available upon request. Summit also tests and certifies roof and wall anchors and other equipment we service and install. We can also test and certify equipment not installed by us. Generally, we do not certify equipment if it has not been tested.

We can arrange your initial certification along with a program for annual inspections. If your building's roof does not have sufficient anchorages we will recommend an evaluation of your suspended maintenance equipment. One factor we consider is anchor spacing. Another is independent anchorages for fall arrest and fall protection when accessing these anchors. Our roof evaluation will be supported by a written report with recommendations for any modifications. Contact us for details.

SYSTEM DESCRIPTION

Anchorage Design Requirements:

Safety anchor system design shall comply with current OSHA, ANSI, and local regulations pertaining to window cleaning and fall protection.

Anchor system shall provide independent fall arrest anchorages in addition to suspension line anchorages for each descent location as required by OSHA and ANSI requirements.

System shall be designed to be compatible with current window cleaning industry standard equipment (examples: rope descent systems, boatswain chairs, swing stages, transportable suspension devises).

Structural Requirements of Anchorages Used for Rope Descent:

Anchorage shall be capable of sustaining a minimum load of 5,000 lb (2268 kg) in any direction without fracture or pullout (yield tensile strength). Anchor yield tensile strength shall be verified by test report.

Anchorage shall be capable of sustaining a minimum load of 2,500 lb (1134 kg) in any direction without permanent deformation (tensile load). Anchor tensile strength shall be verified by test report.

Parapet or guardrails subject to direct loading by workers' ropes, possibly cables, shall be designed to withstand such loading (typically 1,800 lb (816 kg)) without damage to either the structure of the rigging component in contact with it.

** NOTE TO SPECIFIER ** See illustrations on page 12: "Anchor Spacing Diagram" and "Outside Corner Layout Reference Diagram".

Locate primary support and fall arrest anchors in conjunction with areas on facade of building needing to be serviced. Consideration shall be given to the type of suspension equipment that will be used at the building and conditions such as workers' reach, rigging methods, and roof edge conditions. Anchorages shall be unobstructed and located behind and in line with equipment or portion of building they are intended to service,

** NOTE TO SPECIFIER ** This specification does not address powered platform design or roof mounted powered equipment; however, The ANSI/IWCA I-14.1-2001 Window Cleaning Safety Standard states: "Rope descents shall not exceed 300 feet (91m) above grade unless the windows cannot be safely and practicably accessed by other means" (Section 5.7.12). Additionally, The ASME A120 Safety Requirements for Powered Platforms for Building Maintenance Standard should be consulted when designing such equipment.

Rigging Sleeve and Davit Design Requirements:

** NOTE TO SPECIFIER ** See illustrations on page 11: "Suggested Rigging Sleeve Layout" and "Suggested Davit Layout".

Locate rigging sleeves and davits to accommodate suspended maintenance during swing stage operations. Typically, spacing of davits is on column lines or every 20 feet (6 m), on center. Typical spacing of rigging sleeves is 6 foot 8 inches (2032 mm), on center. Placement of supports should allow cables suspending powered equipment to hang either parallel and in plane or slightly angulated with the building facade as required by users. Consideration should be given to operating other equipment that may be required for access.

** NOTE TO SPECIFIER ** See illustrations on page 11: "Suggested Rigging Sleeve Layout" and "Suggested Davit Layout").

Locate independent anchorages for personal fall protection when using rigging sleeves or davits in accordance with provisions of Anchorage Design Requirements.

Davits shall be capable of supporting an ultimate load of not less than 4 times the rated load. The rated load of the davit shall be based on the swing stage hoist and powered platform load capacity, which is frequently 1,000 lb (454 kg) or more.
