SPECIAL FEATURES
Harsco Rail’s New Track Construction (NTC) machine installs new track on a previously prepared roadbed in a continuous operation. The NTC lays 1.5 km of track per day, improving productivity, safety, efficiency, and quality. The NTC works with concrete, pre-plated wood, or steel ties and provides efficient and effective means to laying new track.
FEATURES & BENEFITS
- Works with concrete, pre-plated wood, or steel ties
- Rails capable of being laid: Up to 136 lbs
- Approximately 3 times faster than stick building track
- Working Speed: 10 ties per minute
- Controls the flow of material without overhead cranes
- Move ties to the point of attack
- More precise tie spacing and tie squares
Clipping is carried out by a Nipper-Clipper mechanism on the New Track Construction Machine.
Rail Guide rollers suspended from the Laying Beam. Rails are guided into place on ties by an operator positioned below the beam.
Truss Frame
The NTC unit is supported at one end by a specially modified flatcar running on the newly laid track and at the other end, by a non-powered crawler running on the roadbed. The truss frame contains a conveyor system for carrying the crossties down to the tie laying mechanism which places the crossties on the roadbed at a precise and predetermined spacing.
Tie Pads
Prior to being positioned on the roadbed, cushioning pads are placed on the ties to cushion the effect of steel rails on concrete ties. The entire consist is pulled by a crawler-type auxiliary power unit.
Gantries
A self-propelled gantry, requiring one operator, keeps the ties supplied to the conveyor systems. The tie handling cars are equipped with auxiliary rails which form a continuous running rail for the gantry. Pivoting extensions between the cars allow the gantry to operate on curves. After being deposited by the gantry, the ties move via the conveyor system to the tie drop area.
Fire Suppression
Rail Laying/Threading
After the rail has previously been distributed along the roadbed, it is threaded through guides located at the rear of the tow unit. It is then guided inward to a gauging station. Final placing of the rail on the new ties is controlled by an operator who guides the rail onto the tie seat. The operator is also responsible for the proper alignment of the track.
Contract Services
Harsco Rail’s New Track Construction Contract Services have installed over 4,000,000 ties (equal to 1,515 miles or 2,400 km). NTC Contract Services provide customers with a high quality service by crews that know the machine’s maintenance and operation best.
