Hydraulic weld trimmers are used for removing the excess weld metal after performing the Original Thermit® weld. Goldschmidt offers you the technically best, fastest and most accident-proof type of hot working. The energy expended for the subsequent grinding operations is minimized.
The hydraulic trimming unit comprises a weld trimmer with shearing blades and a drive unit. You can combine your required configuration according to the module system principle. Our trimming units are ideal for removing excess weld metal on flat bottom, grooved and crane rails. The lightweight and long-lasting weld trimmers ensure safe and rapid working based on the rail profile. This reduces the workload required for any subsequent grinding work.
The weld trimmer is equipped with two exchangeable shear blades shaped to the rail section. Two parallel hydraulic cylinders drive the blades towards each other, cutting off the excess weld metal from both sides. The cutting height is limited by the guide shoes, which are located under the rail head. The unit is operated by a 4/3 control valve. Hydraulic pumps with electric motor or internal combustion engine or hand pump can be used as the drive unit.
