Bemo Rail has its own concrete sleeper for crane-rail constructions with heavy wheel loads. The rail is mounted onto a sleeper with a strong spring clip and an elastic sole plate. The sleeper can be installed very precisely in a gravel bed, on sand-cement stabilization, or in repak. The entire rail construction can, if required, be applied in combination with hardening (asphalt, concrete slabs or paving). It is important that the foundation is solidly compact.
