  The REM 44ZII - Ballast Distributing and Profiling Machine {II generation} is a second generation high output fully automated REM Ballast Distributing and Profiling Machine, special development and design by R&D Center “REM" with possibility for manufacture at stage zero in a REM plant by request of the client. This is a second generation of REM machine, automated with built – in autonomous systems: laser, for full remote control, for on-line diagnostics during operation, radars, georadars, GPS, 3D control and other REM systems. Our clients obtain a new class of Ballast Distributing and Profiling Machine with 18 month REM warranty, with high trustiness, high reliability and with high range of efficiency of up to 19 km/h.

The REMTECH ballast distributing and profiling machines the REM44ZII, the shoulder ploughs are positioned in front of the ballast crown plough. The shoulder ploughs profile the ballast shoulders and draw ballast up into the ballast crown to distribute it there according to the positioning of the baffle plates. Surplus material lands in the area around the sleeper-ends. Afterwards, the sweeper unit removes the ballast stones left on the sleeper surfaces and, depending on the equipment of the machine, conveys them to the sleeper ends or on a steep conveyor belt into a ballast hopper. 

   The machine has been designed and tested to operate in extremely severe working conditions like continuous loading, high ambient temperature (climate), dust, severe pollution of the ballast prism, night vision windows for operation/screening upon full guarantee of the safety of the servicing personnel through an innovation system of REM Radar. No matter of the modes of operation and load, the automated system for control guarantees the client in real conditions of exploitation on the rail road reaching of the assigned factory – design productivity of screening up to levels of 19km/h {Running speed while working 0-19 km/h}.

  Successful integration in the machine of patents, REM know – how and innovative REM systems for automation, control, diagnostics and securing of the work of the main key units and components (as per individual requirements and needs of each client), give the opportunity to any client to have a unique modern Ballast Distributing and Profiling Machine with customized requirements: with no analogue worldwide as to volume of further upgrading systems and automation. Each additional system gives unique opportunities for expanding of the capabilities of the machine, which generally result in minimum direct participation and engagement of a machine operator of upgrade, control and supervision during work:

 Variable plough equipment
   During work, the centre plough and the two shoulder ploughs are operated fully hydraulically from the workplace in the cabin. Due to the multiple variations of positioning as well as the fact that all ploughs can operate in both directions, it is possible to perform any desired displacement of the ballast..
  Powerful sweeper unit
  The sweeping device removes surplus ballast from the sleeper surfaces and fills the sleeper cribs. It is suspended on the main frame under the cabin between the two axles. Basically, the output of this unit determines the overall output of the machine during track maintenance, because normally the entire ballast bed profiling is carried out in one pass behind the tamping machine. To achieve this, the sweeper unit is equipped with a brush of large diameter and stepless adjustment of the rotating speed to adapt to the prevailing conditions. It is also capable of performing deep sweeping and sweeping work on switches and crossings.   
  Flexible treatment of ballast
  The ballast collected by the sweeper brush can be treated in two ways. Firstly, the sweeper unit is fitted with a transverse conveyor belt onto which the brush throws the ballast. The conveyor belt throws the ballast, as required, to the left or the right of the ballast shoulder. The machine is equipped with a ballast hopper and is able, by simple switch over, to throw the ballast onto an elevator conveyor belt which takes it directly to the hopper. The stored ballast can be used to fill the tamping zones at any time via four discharging outlets with hydraulic flaps. The positioning of these chutes immediately in front of the centre plough guarantees the technologically correct sequence of operation.

 REM 44ZII is used to realize track bed bi-directional ballast distributing and profiling operation through center plough and shoulder plough;
The sleepers sweeping unit can clean the ballast from sleepers, and then send to ballast hopper through conveyor belt. The ballast is supplemented to both sides of rails where necessary;
Vertical sweeping unit can collect the ballast from track shoulder and at fastenings into sleepers box;
Computer control system and laser radar sensor are provided to automatically distinguish obstacles, make calculations on track sections ballast surplus or shortage, control center plough ballast distribution plate and profiling shoulder angle, real time display working status of center plough and shoulder plough;

 Deutz engine is installed, driven full hydraulically. Maximum running speed under its own power is 100km/h, and the maximum speed in train formation is 120km/h;
Various safety protection devices like high and low gears interlocking, brake protection, reverse protection, working unit locking and emergency reset, etc. are provided to ensure working and running safety.
