Abstract
The device comprises a body (1) for placing on a rail (R) for the purpose of receiving a wheel of a machine to be slowed down and stopped and forming an abutment for the wheel, and an arrangement for connecting the device to the rail. The connecting arrangement comprises a plate (7) carrying elastically yieldable claws (10 and 11) which are maintained spread apart in their position of rest. The plate (7) is adapted to be applied against the rail (R) and is pivotally connected to an arrangement (21) for moving the claws (10 and 11) towards each other for the purpose of closing them around the head of the rail. The arrangement (21) is connected to the body (1) of the device.
