Plasser & Theurer RM 80 UHR
Ballast cleaning machine for switches, crossings and plain track.
* Excellent view during transfer with a driver's control desk in both front and rear cabin
* Additional regulation of ballast flow in the screening unit thanks to hydraulic adjustable baffles
* Optimised three-tier screening unit with separation of oversized stones, remaining spoil less than 3% in the cleaned ballast
* Plough grader after ballast return
* Uniform distribution of the cleaned ballast across the required ballast width thanks to automatic slewing ballast distributing conveyor belts
* Horizontal positioning of screening unit in superelevation
* Reduction of noise and dust emission by covering the lateral chain guides
* Filling ballast underneath the sleepers by trajectory parabola set for ballast return
* Guided excavating chain produces an exactly sloping, straight subgrade
* Efficient 5-finger scraper chain
* Soundproofed cabins for high working comfort
* Spoil loading or lateral discharge at the front in the area of ballast not yet cleaned
* Control of excavating depth using laser guarantees exact longitudinal level
* Foldaway spoil conveyor belt means that no match wagon is required
* Switch over to total excavation in seconds by hydraulic actuation of a flap
* Hydraulic cutter bar locking
* Regulation of ballast thickness by dividing the return flow of ballast as required via distributing conveyorbelts and/or direct from the screening unit
* No hindrance of the subsequent track work, as spoil handling systems are at the front
* Safe flow of material thanks to through-shaped conveyor belts
* Lifting and slewing device close to the excavating chain
* Trackbound ballast cleaning in switches and crossings, extension of the excavating width up to 7.7 m
* Operating reliability thanks to fully hydraulic drive
* Compact single-frame machine
* Tested and proven design, having operated in 17 countries
* Wheelset material as per UIC
* Powerful drive on 4 axles, high traction forces during work and transfer travel
* Two high capacity diesel engines
* Measuring devices for excavating depth and angle of cutter bar (= subgrade crossfall)
* Automatic control for excavating and subgrade crossfall
* Automatic control of height for grading unit
* Quality control by electronic recorder for 6 parameters:
a) excavating depth
b) subgrade crossfall
c) superelevation of the track before cleaning
d) superelevation of the cleaned track
e) track lowering
f) twist of the cleaned track
