РОСТОК Production for the railways Machine for local track alignment МЛП

Machine for local track alignment МЛП

Price: upon request

Machine for local track alignment МЛП is destined for elimination of unexpectedly appearing and requiring urgent correction deviations in condition of a railway track.

МЛП is applied on the local track sections of the main and station railway tracks having 1520 mm track and the rails up to P75 inclusively with wooden or ferro-concrete sleepers, all kinds of rail bindings ballast.

МЛП  is universal track machine of cyclic operation performing simultaneous or independent aligning, straightening and tamping a railway track with dosated road metal adding into the cribs and at the sleeper flanks, leveling the added ballast and also stabilizing and raising transverse stability of aligned track.
Here, in the beginning of МЛП  working process board computer of the machine makes calculation of alignment and dosated ballast adding program on the back track section proceeding from data of a local section condition received during measuring travel of the machine or received from a measuring car (КВЛП type). The machine, from the initial point of the local section, according to  a selected program, makes road metal adding and levels a ballast section, on the way back it executes alignment, tamping and straightening of the track. The machine during final pass after track alignment makes stabilization of the section.

A microprocessor system allows to perform control of all the executive devices of the machine.

Two-sleepers tamping blocks of an original design equipped with automated lubrication system of “Lincoln” Co. (Germany) are installed on  МЛП. Aligning-straightening device is equipped with the roller clamps.

A transmission is made on the base of hydrostatic transmission.

МЛП in addition at libitum of a customer can be equipped with a load manipulator having 3,5 ton-force  lifting capacity, a set of replaceable equipment: timber clamp, hook and clamshell having volume 3,5 m³.

МЛП is able to move on its own on the main tracks to a working place owing to high transport speed, available radio, system of traffic safety, automated system of fire detection and extinguishing in a power plant.

Climatic version type У, allocation category 1 under ГОСТ 15150, but for work at an environment temperature from -10°C up to +40°C when a ballast is not regelated.
