The use of the heavy duty safety tongs makes it impossible to use the hollow rail for the heavy side rails. Therefore, the overspeed protection of the car in this way is of high cost. But this configuration advantage is easy to match parts do not need to develop new products, components, especially for the kind of "on someone can reach under heavy space" and not "will be installed on the counterweight buffer has been extended to solid ground solid pile pier on the elevator, must be installed on the heavy safety clamp, this can put the ascending car overspeed protection device and the safety clamp to be made one reduce the extra cost.
