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 cutting grinder for cutting through a rail of a track includes a detection device for detecting a proposed cutting position. The cutting grinder guarantees simple, user-friendly and efficient through-cutting of the rail.

Abstract: A monitoring device for monitoring a temporary rail connection of two rail portions includes a first fixing element which can be fixed to the first rail portion, and a second fixing element which can be fixed to the second rail portion. The monitoring device furthermore includes a first distance sensor for measuring a first distance between the fixing elements, and a second distance sensor for measuring a second distance between the first fixing element and a first clamping device of the temporary rail connection. The monitoring device allows reliable monitoring of the temporary rail connection. A rail connection system for creating and monitoring a temporary rail connection of two rail portions of a rail is also provided.

Abstract: An impact wrench for tightening and loosening nuts and screws on a track has a vibration decoupling device which serves for vibration decoupling of at least one handle from an electrically operated impact screwing mechanism.

Abstract: A rail grinding machine for grinding rails of a track has a machine frame, on which guide rollers for manual movement of the rail grinding machine in a longitudinal direction are mounted. By use of a cross slide, which is mounted on the machine frame, a grinding unit can be moved in a transverse direction. The cross slide contains a closed cross slide frame, which extends in the longitudinal direction and the transverse direction. The closed cross slide frame enables a simple and stable construction of the rail grinding machine and flexible adjustability of the grinding unit.

Abstract: A vibratory tamping machine for compacting a ballast bed of a track has a vibration mechanism which is driven by means of an electric drive motor. The vibratory tamping machine has a vibration decoupling device, which defines a decoupling plane and separates a working side from an operating side, for the vibration-decoupling of at least one handle. The handles are arranged on the operating side, whereas the electric drive motor and the vibration mechanism are arranged on the working side.

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 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.
