K924Stationary Flash-Butt Rail Welding Machine
The K924 is a specialised stationary rail welding machine developed for production of welded railway crossing, switch and turnout components. Unlike conventional straight-rail production machines, K924 is engineered for demanding component geometries and high-manganese materials.
The current K924 offer describes intermediate welding using a stainless-steel rail insert and welding of high-manganese crossings and switches with cross-sectional areas up to 15,000 mm².
Applications
Railway crossings and switches
Turnout component production
High-manganese rail components
Specialised stationary rail-component manufacture
Key Advantages
Technology & System Architecture
The delivery set includes the K924 welding machine with clamping device and flash remover for the customer-specified rail profile and crossing, pumping station, portable control panel, control cabinet, computer cabinet, computer, laser printer, mounting parts and warranty spare parts / tools.
Control & Quality
K924 uses a SIEMENS programmable microprocessor controller with Bosch Rexroth hydraulic systems. The control architecture supports precise execution of welding programs, real-time parameter recording, full process monitoring and automatic reporting for each weld. An optional GSM module is stated for remote monitoring.
