INTRODUCTIONThe Excel Modular Scaffold Custom Component and Specialty Technical Manual contains components not found in the Excel Modular Scaffold Standard Component Technical Manual, and is a supplemental manual that is to be used in conjunction with the standard manual. All components found in this manual fall under the same standards and conditions found in the standard component manual.

Some items found in the custom/specialty manual are for sale only, or take additional lead time to manufacture. Please ensure the availability of components prior to ordering.

This manual does not replace OSHA 1926/1910 and/or CAL-OSHA documents.1. Compatibility of Excel Modular Scaffold:

Excel scaffold is designed and engineered to be compatible with standard tube and clamp components (i.e.: clamps, poles, ladders and ladder brackets) that are currently available within the scaffold industry. These tube and clamp components are generally used for:

• Tie-offs when needed for seismic considerations.

• When needed to transition horizontally to get around obstacles.

• When needed to transition vertically to get around interference.

• Ladders and ladder brackets for access to work platforms.

• As needed for structural bracing and reinforcement.

2. General erection criteria:

Excel was designed and engineered to be constructed using the same requirements specified by OSHA and CAL-OSHA, that have been historically used with tube and clamp and other types of system scaffold.

Excel expects all users to be familiar with all Federal, State and local regulations governing scaffold construction and use.

Excel expects all users to erect, modify or dismantle scaffolding using only qualified and competent personnel with adequate supervision.

Excel expects all users to provide supervision that is competent and qualified, and who can inspect and sign off on each scaffold before authorization is given for general use.

Excel expects all users to follow common safety guidelines, including: pre-job briefings, procedure compliance, tagging, flagging, wearing of proper PPE, weight-loading restrictions, vertical leg placement, use of diagonal bracing, horizontal wraps, proper use of handrails, mid-rails, toe boards, safety netting, screw jacks, ladders, metal or wood decking, etc.

Excel expects all users to utilize a registered professional engineer (licensed PE) to design and approve drawings, as required by OSHA, CAL-OSHA or any other regulatory agency.

3. Special considerations:

Be extra careful when working with components that telescope.

Telescoping components can move/slide while being transported, handled and passed to other workers.

Many Excel scaffold components swivel, slide or hinge. Use caution when passing to other workers, transporting and installing these items.

Ensure all items containing locks or pins are secured before handling, transporting or passing these items to another worker.

INTENDED USE OF EXCEL MODULAR SCAFFOLD

1. Unless otherwise stated, all load data presented in this manual includes the OSHA (4:1) Safety Factor.

2. Unless otherwise stated, all load data presented in this manual is for downward or compressive loading only.

3. Excel’s scaffold material, when constructed for normal use, is not designed to be up- or side-loaded in excess of OSHA and ANSI requirements. When conditions require special loading, extra design features must be added to ensure proper stability.

4. Once installed and completed, scaffold should be considered part of the customer’s plant equipment. Abuse or mistreatment of the scaffold material should not be tolerated.

5. The scaffold material should be inspected for damage and repaired after any incident which could affect the integrity of the scaffold material, such as:

• The scaffold comes into contact with any moving equipment, forklifts, trucks or trailers, and other types of mobile equipment.

• The scaffold is affected by an unintended load, flanges or piping attached to a crane or come-along, objects dropped from above or swung in from the side, etc.

• Excessive force is applied to the scaffold from abuse or accidental contact.

• The material is modified in any way with a torch, saw or other equipment.

• The material is affected from corrosive chemicals that remove the coating and/or damage the base metal.

• The material is bent or otherwise damaged.

6. The end-user should ensure their competent, qualified individuals and scaffold erection personnel are trained and fully understand the above requirements.

7. When testing of material is required, it should be conducted by qualified personnel in a testing environment. Field testing of scaffold components should not be conducted without a formal test plan approved by the manufacturer.

8. All end-users must be trained in the proper use of Excel Modular Scaffold. The tech manual is provided as a reference for training. New users should examine the Key Rules at the end of the manual.

9. OSHA requires that inspections must be made by the scaffold builder and end-user.

When building scaffold using Specialty Beam Tube Clamps:1) The clamps should only be used for bracing. They should never be load bearing.2) Backup clamps should be used where required to prevent slipping.3) Multiple clamps should be used to reduce the loading when building a scaffold. Standard clamps should be

used as backup clamps (to prevent slip) when a scaffold is installed in high vibration areas or for extended periods of time.

Note: 1) All bolts should be inspected regularly before use.2) Clamp bolts tension greatly affects slip loading.3) Clamp bolts should be tightened between 40 and 65 ft-lbs. Overtightening could damage the threads, or item the clamp is attached to. Undertightening could result in clamps slipping at lower than rated loads.

<<< CAUTION: There is a pinch point located where the beam sides are located on the clamp.>>>

Specialty beam tube clamps are designed to allow the user to brace scaffold and/or create tie points to beams that have very wide flanges.

The clamps attach to the flange of the I-beam and provide a clamp connection.


UNIVERSAL BEAM TUBE CLAMPUniversal beam tube clamps are designed to allow the user to design and build scaffolding in any location where there are accessible, approved i-beams.

The clamps attach to the flange of the i-beam and provide either a clamp connection or a two- (2) cup Excel vertical.

The clamp and vertical can be rotated in any direction. This allows for a variety of scaffold designs to be built.

Used in conjunction with adjustable plank bearers and standard Excel components, can save on time and material needed to build certain scaffolds.

Where a scaffold was once needed to be built from the ground, it can now be built from elevated beams or columns.

Clamp bolt tension greatly affects the slip loading.Clamps should be tightened between 40 and 65 ft-lbs. Overtightening could damage the threads, bolt, or item the clamp is attached to. Undertightening could result in clamps slipping at a lower than rated load.



EXCEL MODULAR SRL ADAPTER

The cable supporting the SRL adapter or other ladder safety device must be secured to a vertical as defined on pages 21 and 22.

The cable must be secured to the vertical three (3) cups (between 16 and 18 inches) above the center of the SRL adapter.

The swivel bolt on the SRL adapter must not be overtightened.

The SRL adapter must be set at the alignment marks, so that cable supporting the end of the adapter is one (1) inch below the center of the adapter.

The SRL adapter is never intended to carry a load. It is designed to align the SRL or other safety device with the ladder access.

As a load is applied to the SRL adapter, it will retract bringing the SRL or other ladder safety device and load toward the scaffold and ladder, allowing the vertical post to absorb the downward load.

The SRL must be fastened high enough above the ladder, so that it is not possible for the person climbing the ladder to come in contact with it.

The SRL adapter is designed to provide support and ladder clearance when using a retractable SRL device to protect workers on the scaffold ladder access.

The SRL or other ladder safety device will drop approximately four (4) inches as the SRL adapter retracts.

EXCEL MODULAR RAPID ACCESS SYSTEM

The Excel rapid access system is designed to provide “stair-like” scaffold access in areas where there is not enough room for a scaffold stair tower. The rapid access system was designed specifically to facilitate getting a worker onto work platforms safely and quickly.

Notes:1) Workers climb the inside of the scaffold tower. The maximum fall is limited to the deck height.2) The opening is a full 36-inches square, which accommodates the majority of workers and their tools.3) The opening is fully handrailed around the opening to prevent accidental falls back into access.4) The rapid access system uses a standard swing gate attached to the horizontal bar for stepping off of the

ladder onto the work deck.5) Allows for the insertion of a standard eight- (8) cup vertical leg gate post to the middle of the board deck.6) Telescoping plank bearer goes under the long deck boards, while allowing the attachment of the shorter deck

boards required for the opening.7) The rapid access system will easily accommodate construction of tower sizes ranging from

five (5) feet x six (6) feet and up to seven (7) feet x ten (10) feet without major design changes.8) Workers are no longer required to climb straight up long vertical ladders, or go over or under mid-rail or top

handrails to get onto the work platform.9) Adjustable hooks allow the ladder to remain at a thirty-degree angle, which requires less effort to climb and

reduces slip hazards.10) The rapid access system will accept telescoping metal toe boards to secure deck boards to the bearers.11) The rapid access system was specifically designed so that it could be used with other modular scaffold

systems with minor modifications.12) The rapid access system does not require any special tools for installation and only a minimal amount of in

service training.13) The rapid access system is only meant to be used in light-duty applications and is limited to a maximum

loading of no more then 25 psf.14) For scaffolds greater than one (1) work deck high, the rapid access system entrances must be installed

in opposite corners of the work platform. The rapid access system is not designed to allow the ladders accesses to be placed on top of each other in the same corner.


Revised: 10/14/09


Rapid access system ladder hooks are easily installed and are attached over the top of a horizontal to provide support for the ladder.

The rapid access system telescoping plank bearer is adjustable for scaffold widths from five (5) foot to nine (9) foot. It is used to provide support for the board deck and supplies a vertical pin connection that allows an eight- (8) cup vertical to be installed for the gate, mid-rail and handrail.

The rapid access system handrail adapter has an Excel end connector on one end and a clamp on the other. It is designed to connect a standard vertical to the middle of any horizontal. For the rapid access system, it is used as the handrail and mid-rail on the back side of the floor opening.

Notes:1) The rapid access system safety gate adapter is designed to connect between two (2) horizontals to provide a

vertical post that can be used to attach the safety gate. 2) The swing gate must always open into the work space, so that it closes against the vertical when it is

completely closed.3) Tube and clamp may be used instead of the rapid access system safety gate adapter.

Clamps should be tightened between 40 and 65 ft-lbs. Overtightening could damage the threads, bolt, or item the clamp is attached to. Undertightening could result in clamps slipping at a lower than rated load.

DESIGN OF SEISMIC SCAFFOLDING

Design and construction of scaffolding in safety-related areas (near rotating equipment, instrument tubing, trip-sensitive equipment, control panels, regulated areas, etc.) does require additional precautions. These guidelines are not intended to be all-inclusive and are for those companies, plants, and clients that do not already have policies, procedures and conditions in place for regulated safety areas and those requiring seismic designed scaffolding. The client’s engineering department should be consulted for exact guidelines, procedures, policies, and any site-specific requirements the plant may already have in place to work in these areas.

For clients that do not have design procedures, policies, and conditions in place, the primary concern associated with scaffold installation in safety-related areas involves damage that could be caused to delicate equipment if the scaffold should slide, change shape, collapse or overturn. In order to prevent any scaffold material from coming into contact with safety-related system equipment, the following guidelines should be observed.

The following guidelines are for those clients or plants that do not have existing guidelines, policies, and procedures in place for tube and clamp or other system scaffold in regards to seismic scaffolds being built.

1) The scaffold shall be designed to meet all Federal, State, local and plant safety regulations.2) The height of the scaffold should not exceed three (3) times the smallest dimension.3) The scaffold should be fastened at the verticals or horizontals with tube and clamp or equivalent to plant

approved structural steel components (i.e. I-beams, handrails, grating, etc.) at the top, middle and base of the scaffold. Diagonal bracing, cantilevered brackets, and side brackets must not be used to secure the scaffold.

4) To prevent movement, the scaffold should be secured at two (2) separate locations, on opposite corners (see sample bracing diagrams). Scaffolds with more than one (1) bay should be secured at as many outside verticals as possible, (see sample multi-bay scaffold diagram).

5) All scaffolds installed near or around safety-related equipment must be secured at as many outside verticals as possible.

6) The scaffold must have an installed board deck or should be braced to prevent the scaffold from changing shape (see sample bracing diagrams on page 39).

7) All pins connecting verticals and horizontals must be securely fastened.8) No unnecessary items or scaffold material should be left unsecured on the scaffold at any time.9) The scaffold should not be left unattended at any time, until it is braced and/or tied adequately with any loose

tools secured prior to leaving.10) The scaffold should be provided with screens, mesh or other suitable means to prevent materials from being

dropped on safety-related equipment. Tying off equipment and tools is acceptable.11) Material or equipment should not be left unattended on any scaffold when the scaffold is not in use.12) Diagonal braces must be installed on all possible sides. Diagonal braces with Excel trigger end connectors

must be tie-wired with one (1) strand of #9 wire or equivalent at the ends. When possible all braces should be wire-tied with one (1) strand of #9 wire or equivalent in the center. Diagonal braces that use 1/2 clamps, and tube and clamp diagonal bracing do not require #9 wire at the attachment points.

13) Horizontal wraps should be placed at 3.5 feet intervals.14) A scaffold with wooden parts, including decking, should be free from holes, saw cuts, splits, and gaps. 15) Decking should be placed with no holes or missing boards to help maintain a square and ridged scaffold.16) All platform decking must be secured (i.e. #9 tie wire or equivalent means) to the horizontal ledgers that are

used for support17) The scaffold must be designed to allow access to safety-related equipment at all times.18) The scaffold should be removed immediately upon job completion.


Revised: 10/22/10


19) All Excel scaffold components, including ladders, gates, cantilever bracket, side brackets, toe boards, telescoping braces, etc., can be used when constructing an Excel scaffold structure, as long as those components were installed properly in accordance with the Excel Technical Manual specifications, and also in accordance with the plants existing seismic procedure guideline criteria that are enforced at each facility for erecting staging in safety-related areas.

Notes:a) The guidelines listed above are for clients and plants that do not already have procedures and policies in

place.b) In the above guidelines, the words shall and must require that the conditions be followed without variance as

it is written.


Revised: 10/22/10


Notes:1) All methods of securing may not be available. Allow a minimum of two (2) methods of bracing, on opposite

sides at the top, center, and the base.2) For scaffolds above fifteen (15) feet in height, bracing should be repeated at seven (7) foot intervals. Individual

plant procedures may vary.3) Use Excel scaffold system connections whenever possible since they do not loosen during a seismic event.4) All clamp connections must be checked for tightness after any seismic event.
