Dig to Deck - Rail Operations & Installation Procedure The Dig to Deck Ramp is Network Rail Approved (PA05/03902) and suitable for use on Rail Track systems.
Operational Safety Precautions [WARNING] FAILURE TO COMPLY WITH THESE REQUIREMENTS MAY RESULT IN DAMAGE TO THE RAMP, MACHINE AND/OR THE RAIL INFRASTRUCTURE.
The Ramp is not designed to be manually lifted and carried. All work on or near the railway infrastructure must be carried out strictly in accordance with railway regulations. Work must be carried out in strict accordance to rulebook GE/RT 8000 and all safety precautions must be followed at all times. When working on electrically operated routes, be sure to observe official regulations. Always observe minimum clearance from overhead wires. Not to be used in 3rd and 4th rail areas. Ensure ground works are completed in accordance to the instructions within this document before attempting to install the ramp. Do not attempt to use the Ramp in areas with any cable connections to the rail.
Operating RRV’s on Dig to Deck Accessing to the Dig via the UTAS The Dig Access Ramp is lifted using 2 lifting points and placed in the dig attaching to the rails. See below:
Ensure the top of the Dig Access Ramp is seated properly onto the ends of the rails ensuring at least 300mm of interface overlap between the dig ramp sockets and the cut rail ends. Before attempting to install the Dig Exit Ramp section the access area needs to be properly prepared. It is necessary that 2 sleepers are removed and that the ballast is levelled in the bottom of the dig. This may involve grading away high spots to achieve finished dig depth level. The ballast needs to be at this level to a distance of approximately 2m (6ft) from the end of the rail/last sleeper. Compact the material as much as possible maintaining the required level. This is to provide a solid base for the Dig Access Ramp. Ensure that the dig access ramp is aligned parallel to the track. It is recommended to also then install the UTAS onto the track directly behind the dig access ramps to assist the machine in on/off tracking when climbed out of/in to the dig. For access to the dig prior to excavation the UTAS can be utilised ensuring that the end of the UTAS centre deck section is aligned the ends of the cut rails, having prepared the sleeper end cess ballast where necessary

Exiting the Dig using the Dig Exit Ramps For exiting to the dig subsequent to excavation having taken place the Dig Exit Ramp is required. it is recommended that the UTAS is also installed ensuring that the end of the UTAS centre deck section is set ½ meter back from the ends of the cut rails having prepared the sleeper end cess ballast where necessary.
Un-Installing the Dig using the Dig Exit Ramps The disassembling process is the reverse of the installing process. Put the ramps sections away first followed by the centre deck section. Always ensure there is adequate possession time planned to safely disassemble the TAS and store all sections clear of the line (at least 3m away).
