Hydraulic rail stretcher R-25
JSC «Kubanzheldormash» has been producing rail stretchers for 25 years and during this time it has gained huge experience in the production of hydraulic track tools for trackmen.
Design features of the rail stretcher R-25
Two hydraulic cylinders serve as connectors of parallel bodies of the rail stretcher R-25. Battening wedges are located in the middle of the bodies which are moved with special directing. Aluminum oil tank. Which contains of two-plunger hydro pumps and a safety valve, is attached to the body of the rail stretcher. Removable handle is attached right to the shaft of the hydro pump and through the hole which is protected by the breather; the tank is filled with working fluid. The work of the hydraulic system of the rail stretcher is protected; working fluid is continuously refined with a mesh filter and special magnet. Under the pressure of the oil, piston rods of the rail stretcher diverge and wedges clamp rail heads, moving them apart from each other at the required distance.

Technical maintenance is required for any hydraulic device. Specialists point out several types of technical maintenance for rails stretcher R – 25: monthly, seasonal and annual services. The first type of technical maintenance is performed in the beginning and at the end of every working shift and consists of basic operations, the stretcher is cleaned from dust, dirt, fuels and lubricant oils, then the stretcher undergoes an external examination for detecting visual damages of the details, weld cracks and other malfunctions. Seasonal service is performed twice a year and the final one is annual. However, the annual technical maintenance is advised to perform in specialized service centers equipped with necessary testing equipment.
