SECTION 1. FOREWORD

1-1. Special User Attention Skytron’s objective is to provide a program and guideline to assist individuals (hospital owners, architects, structural engineers) responsible for the design of mounting structures.

The mounting structure of a Skytron fixture should always be considered the most important detail of any project prior to installation. Skytron’s ceiling mounted systems depend upon properly designed and installed mounting structures to deliver years of dependable, service-free performance.

We realize that individual mounting structures vary in design due to unique structural requirements, physical obstructions, structural member availability and room layout limitations, to name a few.

The mounting structure design in this Mounting Structure Guideline Booklet is a successful, proven design. The design consists of a welded, “flanged tube” assembly combined with (4) angled sway braces (“kickers”). A structural steel tube combined with welded steel plates on each end facilitate its attachment to the structural ceiling and provide an attachment point for the Skytron fixture. This is a simple effective design that is forgiving to restricting structural conditions that are usually encountered during fabrication.

This design also eliminates “guess work” by the steel fabricator when compared to structures that are fabricated on site with angle iron. In many cases the “flanged tube” assembly can be pre-fabricated reducing the on-site construction time and eliminating the need to correct structural problems associated with angle iron structures.

The process of building a proper mounting structure can be complemented with Skytron’s continued support on the project. Once the structures are fabricated, Skytron will perform a visual inspection and on-site consultation followed by an actual performance test. The performance test of the structure essentially involves hanging a “test jig” from the structure, and then measuring the amount of rotation that occurs at the mounting plate using an inclinometer (digital level). The test jig is similar in size, shape, and weight to a Freedom boom. Once the test jig is installed and the proper weights have been added to simulate the product’s moment load, a reading is taken on the digital level to verify that there is no more deflection than is stated in section "8-3.

Load Simulator Weight Matrix" on page 13 on the mounting plate when the specified load is applied.

Rotation of the mounting plate causes the radial arm(s) to become out of level and to drift. For a structure to meet Skytron specifications, we require that the mounting plate does not have any more deflection than is stated in section "8-3. Load Simulator Weight Matrix" on page 13 .

The testing process should occur in the early stages of construction to provide optimal time if additional reinforcement is needed on the structure. This should be performed prior to the completion of the finished ceiling.

Skytron’s program is available to help you and provide you with the necessary counseling. However, the final responsibility to insure that the structure is adequate and meets specification lies with the structural engineer and the contractor for the project.

Our support services are geared to minimize the effort on all parties involved and to insure a successful product installation.

This Mounting Structure is applicable for all SKYTRON® Freedom boom models.

We recognize that not all situations will permit the use of this “Tube Structure”. Please contact Skytron with your special needs so that we may be able to guide you to other alternatives.

SECTION 2. INTRODUCTION

Simulation testing on all Freedom booms must be performed by an authorized Skytron representative ONLY.

Testing weight and moment load on Freedom booms is hazardous work. It is important to use proper Personal Protection Equipment (PPE) and adhere to OSHA (Occupational Safety and Health Administration) for materials handling and storage for the safe equipment used in hoists and with slings.

CAUTION

CAUTION with safety alert symbol indicates a hazardous situation that, if not avoided, could result in minor or moderate injury.

CAUTION

CAUTION without the safety alert symbol, is used to address practices not related to personal injury but with a possibility of damage to equipment.

Check valves must be removed during brazing to prevent damage to O-rings. Check valves come in two different lengths. Keep Instrument Air and Oxygen separate from the others (Figure 2).

NOTICE

Indicates important information not related to personal injury.

2-2. Skytron Supplied Components Skytron supplies some components to assist in the design and construction of the mounting structure:

2-2-1. Installation Kit Skytron provides an installation kit which can be shipped in advance and contains all of the Skytron supplied components required for pre-installation and the fabrication of the Freedom boom mounting structure. The Installation Kit includes the following:

■ Customer approved room layout and Freedom boom configuration drawings

■ Freedom boom mounting plate

■ Medical gas riser plate with appropriate medical gas connectors

■ Check valve removal tool

■ Electrical junction box

This publication is meant to provide the information needed to design and build a mounting structure that will provide the proper support for a SKYTRON®

Freedom boom fixture as well as the guidance for supplying the necessary services.

The responsibilities and items supplied by both Skytron and the Customer for pre-installation of the fixture will vary depending on the equipment and services that will be provided on the Freedom boom fixture. The mounting structure requirements however, are the same for all models. The structure design is based on the heaviest Freedom boom model with the greatest moment load. By using this criteria, one structure design can be utilized to minimize design costs and provide adequate support for future modifications. If applicable, specific Seismic Calculations can be provided from Skytron.

The Mounting Structure design should always be approved by a Structural Engineer. An inadequate Mounting Structure may allow drifting and other performance problems for the fixture. Equipment warranty or service charges due to an inadequate Mounting Structure are at the customer’s expense.

Skytron does not warrant or certify superstructure designs.

If the optional Interstitial Shroud is applicable, please refer to document TEC-H-0129 for additional pre-installation requirements.

This publication is intended to address various areas and responsibilities of multiple individuals. It is important that this information is shared with:

■ Architects and Structural Engineer

■ Electrical Engineer

■ Medical Gas/Piping Engineer

■ Communication/Video/Data Engineer

■ Project Manager(s)

SECTION 4. STRUCTURAL REQUIREMENTS

4-1. Mounting Structure Components The fabrication of each mounting structure may be slightly different but they each require the same basic components to ensure stability. Refer to Figure 1 on page 7 for the relationship of these components.

Sway Bracing (by others) Sway bracing is designed to rigidly affix the Mounting Plate to the structural ceiling. The primary purpose of Sway Bracing is to eliminate sway, or lateral twisting and flexing of the mounting structure as it “reacts” to dynamic load changes caused by moving the fixture radial arms. The sway bracing should be welded to the Mounting Plate and extend away from the center of the mount. A minimum of four sway braces placed 90° apart at a 45° to 60° angle is recommended.

Minimum recommended material for sway bracing is 3” x 3” x 1/4” angle iron. It is recommended that in all applications that the sway bracing be fastened to the structural ceiling.

Structural Ceiling Plate (by others) The Structural Ceiling Plate rigidly attaches the mount to the Structural Ceiling using structural anchors appropriate for the ceiling construction. The structural ceiling plate should be a minimum of 1” thick ASTM A36 steel plate with the appropriate mounting holes size and spacing.

Expansion Anchors Test 50% of the anchors at 2000 pounds (907 kg) tension, or 50 ft. lbs. (68 N•m) torque per CBC 1925A.3.5. Installed anchors must meet the following criteria:

1. Hydraulic Ram Method: The anchor should have no observable movement at the applicable test load. For wedge and sleeve type anchors, a practical way to determine observable movement is that the washer under the nut becomes loose.

2. Torque Wrench Method (Wedge or Sleeve Type): The applicable test torque must be reached within one-half (1/2) turn of the nut.

Testing should occur no sooner than 24 hours after installation of anchors. If any anchor fails testing, test all anchors until 20 consecutive anchors pass, then resume the initial testing frequency. Test equipment is to be calibrated by an approved testing laboratory in accordance with standard recognized procedures.

Support Tube (by others) The Support Tube required to attach the Mounting Plate to the Structural Ceiling Plate is ASTM 500 Grade B, 6” outer diameter tube. Support Tube is to be welded to Structural Ceiling Plate and Mounting Plate. A minimum of 6 gussets placed 60° apart should be welded to the support tube at the structural ceiling plate and the Mounting Plate.

Mounting Plate (Skytron supplied) The 17.5” x 17.5” x 1” ASTM A36 steel Mounting Plate is a Skytron supplied item. The Support Tube and Sway Bracing are welded to the Mounting Plate.

The mounting plate contains the corresponding bolt pattern for attaching the fixture and provides the mounting areas for the junction box and gas riser plates.

4-2. Mounting Structure Design Seismic structural applications differ. Please contact your local Skytron distributor for specific calculations.

NOTICE

The mounting structure must be designed and fabricated to position the bottom of the SKYTRON® Mounting Plate as shown on the site specific elevation page.

The bottom of the mounting plate location is a critical dimension to accommodate the proper clearance required for ceiling cover function. The mounting plate must be perfectly level (±0.1°) and allow no more deflection than is stated in section 8-3 on page 13 at the mounting plate when the specified load is applied.

NOTICE

The mounting structure must be tested for strength and stiffness prior to installation of the fixture.

A Test Jig is available from Skytron that includes all components and documentation required for performing an approved Mounting Structure test.

Refer to SECTION 8 on page 12 for testing procedures.

NOTICE

Please consult your Skytron representative during early stages of construction to facilitate this process. The testing process is a required documented function prior to closing of the finished ceiling.

Ceiling Requirements A 24” x 24” access door must be mounted adjacent to the mounting structure for entry by service personnel for service access.

Skytron provides a ceiling cover designed to fit the ceiling cutout see "3-1. Standard Mounting" on page 5.

SECTION 5. ELECTRICAL REQUIREMENTS

Each Freedom boom fixture is fabricated in accordance to the specifications required by the customer.

The configuration drawings supplied by Skytron will indicate the type and quantity of circuits required.

Skytron provides all fixture wiring and electrical materials for connection from the fixture to the facility provided supply.

Skytron supplies an electrical junction box to facilitate field wiring, with an optional partition for critical and normal power (if applicable), for up to six circuits to be mounted on the mounting plate in the correct position (Figure 1).

If the boom is equipped with the Active Assist system, it will require either a separate circuit (120V, 0.5A draw) OR if tied into another circuit, a DPST disconnect switch to isolate it, should service be required.

If a motorized height adjustable arm is utilized, a Skytron provided enclosure/junction box (8"L x 6"W x 4"H) must be remotely mounted within 24" of the mounting structure (by the contractor). Either this remote enclosure will require a separate circuit (120V 2.5A draw) OR if tied into another circuit, it will require a DPST disconnect switch to isolate it, should service be required.

Typical wire type is 12AWG, 600V, XHHW-2. Each circuit requires a separate, properly circuit protected, 120VAC, 60Hz power supply line enclosed in rigid metal conduit.

Any electrical material and labor required for connection to the Skytron fixture and or electrical enclosure is to be provided by the contractor or customer. All wiring and materials are to be in accordance with federal, state and local codes. It is the customer's responsibility to meet conformity to NFPA and NEC standards with respect to the number of receptacles provided in a patient care area based on the customer specific drawing.

NOTICE

If the optional Interstitial Shroud is applicable, refer to document TEC-H-0129 for additional pre-installation requirements.

SECTION 6. COMMUNICATIONS REQUIREMENTS

Each Freedom boom fixture is fabricated in accordance to the specifications required by the customer.

Each Freedom boom fixture is fabricated in accordance with the specifications required by the customer.

The configuration drawings supplied by Skytron will indicate the type and quantity of gas supply lines required. D.I.S.S. connection medical grade hoses connect the fixture to the riser plate connectors. The customer is responsible for delivering the appropriate medical gas from the facility supply to the riser plate connectors and for the design of a medical gas system with adequate flow capacity capable of compensating for the accumulative flow restrictions associated with conventional construction methods i.e. flex gas hoses.

Skytron provides medical gas riser plate(s) and the appropriate connectors for attachment to the mounting plate. The riser plate(s) must be top mounted to the mounting plate and will accommodate up to six gas connections on each plate. The connectors are D.I.S.S. type medical gas connectors with removable single check valves and provide a 1/2” copper tube for attachment to facility supply lines. Caps are provided with Vacuum & WAGD gas connectors to facilitate testing procedures. If more than 12 gas connections are required, the contractor will need to remotely mount additional riser plates.

All connection and testing of medical gas piping to be performed in accordance with NFPA 99-2012 OR CAN-CSA Z 73961-12 requirements.

7-1. Recommended Gas Riser Placement

NOTICE

If the optional Interstitial Shroud is applicable, refer to document TEC-H-0129 for additional pre-installation requirements.

A six inch clearance must be maintained between the finished ceiling and the gas inlet tubes. If this clearance cannot be accomplished at the mounting plate, then horizontal or remote mounting of the riser plate will be required (by the contractor). When mount is in center of room, riser plate should face head end of room, when mount is near walls, riser plate should be adjacent to wall. If more than one riser plate is required they should be placed next to each other.

SECTION 8. MOUNTING STRUCTURE TESTING

Each mounting structure must be tested by a Skytron representative to verify there is no more deflection than is stated in section "8-3. Load Simulator Weight Matrix" on page 13 of rotational movement at the mounting plate prior to installing a fixture. A mounting structure test Jig is available from Skytron to facilitate this process. The mounting structure test Jig is a fixture that simulates the weights and moment loads created by the SKYTRON® fixture. It consists of a hub assembly, an upper and lower radial arm, a chain fall, weight support tube and six 100 pound weights (Figure 3).

The drawing package and the test jig instructions are required to perform an accurate test.

The test jig instructions include the load simulator weight chart, the test jig report form and complete instructions for performing the test.

WARNING

Simulation testing on all Freedom booms must be performed by an authorized Skytron representative ONLY.

WARNING

Testing weight and moment load on Freedom booms is hazardous work. It is important to use proper Personal Protection Equipment (PPE) and adhere to OSHA (Occupational Safety and Health Administration) for materials handling and storage for the safe equipment used in hoists and with slings.

The Skytron weight and moment load simulator is a device which simulates the moment load on an actual ceiling mounted articulating fixture in order to test the weight bearing capacity and performance of the Freedom mounting structure.

Skytron recommends using a 600lb [272kg] maximum load simulator to test all mounting structure systems for maximum load and weight capacity.

Load simulation is an essential part of readiness assessment and provides reassurance the mounting structure can accept larger more complex articulating systems if the need arises for equipment changes or future expansion.

In the event that the mounting structure system cannot deliver performance for the maximum load, the weight matrix provided below provides lesser fixture weight and moment load as a means to ensure that the minimum criteria is met.
