Oleo has developed a range of deformation tubes as summarised below:
Start Force: 50kN to 250kN
Stroke: 50mm to 400mm
These can be fully customised to meet customer requirements and meet demanding specifications such as high bending forces that may be required for train rescue scenarios.
Bending strength is important to ensure integrity during impact and also to permit lifting of vehicles at coupler positions in order to return trains to the track following derailments.
Simple replacement can be made by releasing the capsules between muff clamps.
