Mobile Access Tower

 

A galvanized steel Mobile Access Tower (MAT) provides access to the vehicle while on the launch mount via five platform levels. The platforms are retracted during stacking operations and movement of the gantry.

Capability

  1. BulletThe MAT is a 75 foot structure with growth capability built in to the basic structure for a 90 foot structure

  2. BulletA minimum of 12 foot structural clearance (less flip platforms) is provided inside the processing compartment.

  3. BulletThe main doors open 180 degrees to open one whole side of the processing compartment.

  4. BulletProvides five variable platform levels with tolerance of plus or minus approximately 12”.

  5. BulletPlatform rated workload = 70 lb/ft2.

  6. BulletAn easily removable work platform access is provided below the base of the launch vehicle to support umbilical connections and pre-launch processing operations.

  7. BulletThe MAT design supports an umbilical pole that is free-standing and self-supporting while the MAT Environmental Enclosure is in the fully closed position. Provision is made for tensioning the umbilical guy wires prior to gantry roll back.

  8. BulletA 24” x 24” cable trench is provided under the rails for vehicle cables and HVAC duct. This trench allows direct, straight access from the LEV to the center point of the launch stand.

  9. BulletAccess is provided for rocket thermal cover HVAC duct and vehicle umbilicals to the base of vehicle with MAT in place and doors closed. The MAT doors are capable opening and the MAT is capable of retracting without disconnecting these items.

  10. BulletProvides lightning protection and certified grounding points

  11. BulletConduits for 120VAC electrical power are provided to each work platform level. Minimum electrical distribution is provided to support 120VAC service at each level.

  12. BulletLighting is provided in stairways and in the processing area for OSHA access (plug in halogen units are available for high intensity spot lights at specific work areas.)

  13. BulletThe gantry provides protection for launch vehicle against open exposure to wind and rain on all four sides and the top of the processing and stairwell compartments.

  14. BulletThe gantry was designed to meet International Building Code (IBC) with Seismic Zone 4 requirements and 90 mph 3 sec wind gusts without contacting the emplaced vehicle.

  15. BulletThree rated fall protection tie off points (one on each wall) and guardrails are provided on all work platforms.

  16. BulletGuardrails are provided on all staircases.

  17. BulletFire extinguishers are available at each work level.

  18. BulletConduits for communications stations are provided to each work platform level.

  19. BulletCommunications are provided to the gantry by portable communication panels with the capability of reaching each platform level.
