Mobile Rail Welding Machines
Mobile flash-butt rail welding machines for welding directly on track. The range covers different upsetting and clamping forces, upsetting strokes and application requirements, allowing the equipment to be matched to specific field-welding conditions.
● K900A-1● K900T● K920● K922-1● K930/K945/K950/K955● K1067

Stationary Rail Welding Machines
Stationary flash-butt rail welding machines for rail-welding plants and specialised production applications. K1000 and K1100 are designed for stationary rail welding, while K924 is intended for specialised welding of railway crossing components and associated rail parts.
● K1000● K1100 ● K924

Containerised Rail Welding Solutions
Integrated containerised rail welding systems. A single transportable module combines the welding equipment with the required auxiliary systems — hydraulics, cooling, controls, autonomous power and handling equipment — according to the selected configuration. Containerised execution is available for applicable KZESO machines except K924.
● K924

Mobile Rail Welding Complexes
Complete mobile rail welding complexes integrating rail welding equipment, a transport platform, rail-running system, power generation, hydraulics, cooling, controls and welding-machine handling equipment. The principal solution in this category is KCM007.
● KCM007

Road-Rail Vehicles
Specialised road-rail vehicles designed for operation on public roads and railway track and for integration of specialised equipment. This category includes VHD-2.
● VHD-2

Other Specialised Equipment
Additional KZESO specialised equipment for rail-welding production and railway infrastructure. The range includes the KPM Press for Testing Welded Rail Joints and KZF 11 / KZF 13 contactors.
