A device to pull out railbolts

This manually operated device has been designed to pull railbolts out of concrete or wooden sleepers. The measurement can determine the resistance between the bolt and the sleeper
he equipment consists of a pulling device and a measuring - data storing unit. While pulling the bolt out, it stores the displacement - force diagram. Before starting the measurement special lengthened shaft measuring bolts have to be driven in. During measurement the device bears up the sleeper on the two sides of the rail. The design of the equipment enables bolts to be pulled out of any type sleepers by the help of the specific measuring bolts.
The rigid structure ensures that up to 200 kN the measurement by pulling can be performed without any deformation.
