Various tools are used for the manipulation of rails. These are primarily for the unloading or loading of rails and the longitudinal distortion.
Rail loading and unloading device
Various designs of loaders are available, including self-propelled equipment, but also loading cranes, which can be mounted on rail cars. A rail lifting clamp is necessary for the safe lifting and manipulation of rails. It is important to note that when rails are unloaded there should not be too much deflection or elongation and care should be taken not to damage the rail surface.
Rail manipulation devices
After rails have been unloaded they can be moved with different devices to wherever they may be fitted. These devices are also available in different designs as relaying stands, relaying wagons without power equipment, and relaying wagons with their own power equipment.
Rail relaying equipment
An appropriate number of devices are used for the lifting and longitudinal and transverse movement of rails of any length. A roller carrying clamp with hardened roller serves for the longitudinal movement.
Mobile rail relaying devices are also used.
This device is used for the longitudinal pulling out of rails to prevent them being damaged by any possible scratching by excavators.
Rail pulling device
In order to get rails into a precise position, pulling devices are required which can work with millimetre precision. Manual versions of these are available and versions with hydraulic drive which can be operated by a small power unit.
In order to facilitate the pulling out of rails, rollers are put under the rails to reduce the frictional resistance.
Hydraulic rail lifting device
Recently, hydraulic rail lifting devices have also been used. Thus, previously released rails have been lifted, for example, in order to change rail pads. The propulsion of the device is carried out mechanically.
After unloading the rails from the carrying train it is necessary to lay the rails down in a stable position. This tool is perfect to do so and is also very safe.
