Boiler Access



WINSAFE’s Throat Maintenance Work Platforms provide personnel access across the boiler throat, through a series of portable aluminum planks that straddle the throat area.

  • Lightweight aluminum construction, with recessed carrying handles and a non-skid checker plate deck surface.
  • Tool-free assembly.
  • Modular design accommodates multiple length configurations.
  • 20” wide panels fit easily through openings.
  • Designed for harsh environment use.
  • Meets applicable OSHA requirements.

INTERLOCKING DECK SYSTEM

  • Interlocking panels provide a continuous work surface.
  • Vertical stabilizer braces adjust to contact the throat face.
  • Feet adjust to keep the deck level on the sloped surface, conforming to the contour of the boiler and accommodating throat tube deflections.
  • 32 lbs weight typical.

For applications that have encountered significant slope damage (thermal distortion, “clinker” impact), or where multiple size boiler use is desired, WINSAFE has developed a new throat scaffolding system that provides an even greater range of adjustment.

INDIVIDUALLY ADJUSTABLE DECK SYSTEM:

  • Adjusts to provide 36” to 60” coverage.
  • Decks are set in place individually, following the changes in level resulting from the tube damage.
  • Support feet and throat engagement legs telescope to the required extension; spring-loaded locking pins engage automatically to maintain position.
  • Hinged panels at the ends of each deck cover the end gaps through the full adjustment range.
  • 50 lbs weight typical.
  • Where full adjustment range is not required (36” to 46”), decks without hinged side panels can be accommodated by special order (40 lbs weight typical).



The WINSAFE Knee Brace provides ideal temporary scaffold bracing to support access planks for working in upper furnace boiler tube panel areas. Workers simply tighten the exclusive ¾ clamp around the tube at the top and bottom locations on a pair of braces and then place scaffold planks across them to form a work deck.

  • Ease of installation: Quickly installs without tools or loose parts. Repairs in this area no longer need extensive, time consuming scaffolding setups.
  • Brace lengths can be customized to accommodate specific platform sizes or the Telescoping Knee
  • Brace can be used universally for platform widths ranging from 18” to 24”.
  • Clamps are adjustable from 1 ¾” to 2 ½”. Tube sizes can be accommodated by special order.
  • Can be designed for use with positively locking plank sections.
  • Lightweight aluminum construction (as little as 12 lbs. each) provides 800 lbs. load rating per pair (4:1 safety factor).
  • Meets applicable OSHA & ANSI requirements for temporary fixed scaffolding.
  • Folds flat for convenient storage.


The WINSAFE sectional Access Ladder provides worker access to upper boiler panels in the furnace. Using the exclusive ¾ clamp, workers attach one section at a time to a boiler tube and then climb up to continue adding sections. Heights of up to 70’ can be obtained, offering access to the installation point of other boiler access & work deck solutions.

  • Ease of installation: quickly installs without tools or loose parts.
  • Modular sections interconnect and pin lock together to a provide a continuous ladder.
  • Side rail extrusion design ensures subsequent sections can only be added in the correct orientation.
  • Clamps are adjustable from 1 ¾” to 2 ½”. Other tube sizes can be accommodated by special order.
  • Clamp stand-off brackets can be made to accommodate various depth requirements.
  • Ladder sections are available in 4’ lengths; a minimum of two sections assembled together are required for use. The clamp must be secured prior to climbing and installation of subsequent sections.
  • Lightweight aluminum construction (4’ section weighs 15 lbs.).
  • 300 lbs. (1 person) capacity rating (4:1 safety factor). A minimum of two sections assembled together are required for use.
  • 6’ sections with dual clamps can be accommodated by special order where specific height and spacing requirements dictate.
  • Meets OSHA & ANSI requirements.



The WINSAFE Horizontal Plank Brace provides ideal temporary scaffold bracing to support access planks for working in upper furnace boiler tube panel areas. Using the clamp jaws, workers simply tighten one end to a reheat tube and the other to a superheat tube, placing scaffold planks across a pair to form a work deck.

  • Ease of installation: Quickly installs without tools or loose parts.
  • Repairs in this area no longer require extensive, time consuming scaffolding setups.
  • Adjustability provided by the telescoping feature allows for use on boiler tubes that are distorted or out of line.
  • Clamps are adjustable from 1 ¾” to 2 ½”.
  • Other tube sizes can be accommodated by special order.
  • Can be designed for use with positively locking plank sections.
  • Lightweight aluminum construction provides
  • 500 lbs. load rating per pair (4:1 safety factor).
  • Meets applicable OSHA and ANSI requirements for temporary fixed scaffolding.



The WINSAFE Nose Maintenance Work Platform provides ideal personnel access just above the upper nose arch of the boiler in order to service reheat and super heat platens.

  • Ease of installation: quickly installs without tools or loose parts.
  • Braces are clamped to screen tubes or to the back of platen assemblies using the exclusive clamp.
  • Clamping mechanisms and foot & leg configurations can be customized to suit the application.
  • Workers can build scaffold on the floor decks or use other WINSAFE access products to gain full access to the upper reheat and superheat areas.
  • Lightweight aluminum construction, knocks down to fit through 20” opening.
  • Designed for harsh environment use.
  • Meets applicable OSHA requirements.



The WINSAFE Safety Tie-Off Clamp is an exclusive fall protection anchorage connector, designed to be clamped to vertical tubes in boilers.

  • Made from durable aluminum and steel components.
  • Designed to meet OSHA required maximum fall arrest force. (*See Reverse)
  • Clamp range 1 ¾” to 2 ½”.
  • Other tube sizes can be accommodated by special order.
  • Quickly installs without tools or loose parts.
  • Position at shoulder height and tighten firmly to the tube.
  • To be used with a shock absorbing lanyard (maximum
  • 4 ft. in length), in combination with a full body harness.
  • (Refer to WINSAFE’s Fall Protection product offering.)
  • Meets applicable OSHA and ANSI requirements.

The Safety Tie-Off Clamp is designed to serve as a safety anchorage point for workers performing boiler maintenance work. The device can be secured to structurally sound boiler tubes from 1-3/4” to 2-1/2” in diameter. A wire rope loop extends beneath the device to provide a point of anchorage for one worker’s safety lanyard.

The product has been designed to meet the applicable requirements of OSHA Standard 1926.502 (Safety and Health Regulations for Construction; Fall Protection Systems Criteria and Practices) and OSHA Standard 1910.66

(Occupational Safety and Health Standards; Powered Platforms for Building Maintenance), Appendix C (Personal Fall Arrest System).

These standards require that fall arrest anchorages be capable of supporting at least 5,000 lbs per employee attached or two times the maximum fall arrest load when used as part of a complete personal fall arrest system under the supervision of a qualified person.

A shock absorbing lanyard, mandated for use with the Safety Tie-Off Clamp along with a full body harness to constitute a complete fall arrest system, has a maximum fall arrest force of 900 lbs.

Safety Tie-Off Clamp samples have been load tested to verify that the clamp remains in place on a tube with 2,500 lbs suspended on the wire rope loop, exceeding the requirement and providing a safety factor of greater than 2.7.
