Abstract: A machine for track maintenance is manually displaceable on a track. The machine has a work module with a handle, a working tool powered by a drive and a machine frame configured to be guided on a rail of the track. The work module is detachably connected to an energy module and the energy module has an electrical energy store and output contacts. The output contacts are detachably connected to input contacts of the work module. The work module has as the drive an electric motor supplied with electrical energy from the energy store. This solution results in a high degree of overall efficiency because the energy available in the energy store serves for the largest part for covering performance peaks.

Abstract: A maintenance vehicle has side walls for creating a work space, delimited by the same, for working personnel situated on a track. The side walls are arranged on a vehicle frame and configured to be distanced from one another in a transverse direction of the vehicle. For treatment of a track section situated within the work space, an industrial robot is arranged on the vehicle, having at least three motion axes, media couplings for energy supply as well as a tool coupling for selective connection to a track treatment tool.

Abstract: A screwing machine tightens or releases rail fixing screws. The screwing machine contains a machine frame which can be rolled on a track, handles for moving the screwing machine, a motor for applying a torque to a screw head, and a device for transmitting a torque. A measuring device is provided opposite the machine frame in order to detect a reaction torque of the motor. The motor is actuated in order to limit the torque depending on the reaction torque. The reaction torque is used as a reference variable. The reaction torque is applied to the machine frame by the motor and is ascertainable with a high degree of precision by a simple measuring device. In this manner, a simple and robust design and a precise rotational speed limiting function are implemented.

Abstract: A maintenance vehicle has a vehicle frame, supported on on-track undercarriages, on which are arranged two side walls extending in a longitudinal direction of the vehicle and adjustable with respect to one another and relative to the vehicle frame in a transverse direction of the vehicle by way of drives. The vehicle is equipped with at least one load crane which is displaceable on a crane guide that extends in the transverse direction of the vehicle. The crane guide, designed to be elongatable in the transverse direction of the vehicle, is connected at each end to a side wall.

Abstract: A safeguarding system for an emergency fish-plate connector is fastened to a rail base of the rail and has a distance measuring device for supplying a measuring value registering a distance a between the emergency fish-plate connector and the safeguarding system. For transmission of the detected measuring values and of an identifying signal—enabling a locally unambiguous correlation of the emergency fish-plate connector with regard to the track—to a control station, the safeguarding system is equipped with a radio device.

Abstract: A hand tamper for tamping ballast of a track includes a drive motor for rotation of an imbalance or unbalanced weight and a barrel tip which is approximately V-shaped in longitudinal section and is fastened to a lower end of a barrel connected to the drive motor. A plurality of barrel fins extending in a longitudinal direction of the barrel are disposed on a lower barrel section adjoining the barrel tip. The barrel fins are spaced from one another relative to a barrel cross-section, extend radially from a barrel surface and are elongated into the barrel tip.

Abstract: A hand-held tamper for underfilling ballast of a track. The tamper has a drive motor for the rotation of an unbalance and a tamping shovel fastened to a lower end of a shaft which is joined to the drive motor and has a longitudinal axis. The shovel consists of two shovel halves each joined to the shaft. Each shovel half has an upper shovel part nearer to the drive motor and a lower shovel part positioned at a first angle <180° in relation thereto. Both shovel halves are disposed at a second angle <180° relative to one another when viewed in the direction of the longitudinal axis of the shaft.

Abstract: Arranged on a rail loading train for transporting long-welded rails is a fixing device for anchoring the rails. The fixing device is composed of a number of clamping devices, each provided for anchoring a single rail. The clamping devices are configured to be adjustable relative to the rail loading train in a longitudinal direction of the wagon by a displacement drive.

Abstract: A motor unit (21) of a machine (1) mobile manually on a track is equipped with hand grips (27) and connected by means of a detachable coupling (20) to a work unit (12). The motor unit (21) is composed of a motor (22), a hydraulic pump (23), a hydraulic tank (24), a cooler (25), and an electric generator (26).
