High speed backstop
Nonreturn devices for high speeds
VULKAN nonreturn devices are some of the best and most cost-effective products of their kind and can carry out several functions fully automatically, without working with mechanical or hydraulic auxiliaries. The blocking system reacts immediately and precisely.
VULKAN nonreturn devices are safety mechanisms, which prevent machine movement in certain directions of rotation (Counter Recoil) and the machine runs freely in the opposite direction (freewheeling). Typical applications include conveyor belts, elevators, cranes, speed reducers and pumps and are available with or without radial bearings and torque arm.
