Launching Girder

General Overview

The Launching Girder (LG) is a purpose-built steel frame designed for moving the pipe rack or preassembled rack (PAR) modules along the trestle from their initial position to the required installation location.

  • The main structure consists of five modules which are bolted together by splice connections.
  • The LG is equipped with a longitudinal positioning frame known as Hook-On-Jack (HOJ), which stops the LG at the destined location and acts as a high precision tool in the final longitudinal positioning of the LG.
  • The skidding of the launching girder is done using a traction and tension winch. The traction winch is located at the rear of the LG and is used for transporting the LG via a tensioned wire rope Ø38.1mm.
  • The LG is supported by a minimum of 6 Hillman roller boxes at all times. There are 36x150-XNTW and 36x200-XNTW roller boxes available. The 200MT roller boxes have transverse restraints to keep the LG aligned while in motion.
  • The LG comes with hydraulics to support the installation of PAR Modules. The equalizing jacks are used for compensating the deflection in the PAR Modules experienced by LG during its motion.
