Emergency Manual Opening Device

The rail clamps are supplied with suitable tierods complete with nuts. Acting on two tierods by a common too l-key it is possible to open the rail clamps in case of emergency (lack of electric energy or hydraulic unit broken)

Applications

These rail clamps are static storm brakes suitable for small to medium forces: from 25 to 800 kN. These rail clamps are to be considered as parking devices (safety against the movement caused by wind) that work pressing on rail sides. They are spring actuated (the spring generate the closing force) while an hydraulic cylinder fed by a suitable hydraulic unit provides the opening. Each rail clamp is composed substantially of one steel frame, two rail guides and two jaws operated by springs trough suitable levers. The rail guides are placed into the frame in such a way to follow side displacement between crane and rail. The guides are constituted by plates properly shaped acting on side of the rail. In particular cases, rollers acting on the top of the rail can be used.

Operating Restrictions

Braking shoes of our rail clamp have been designed to work on common market rails whose hardness is between 200 and 270 HB ( (= 70 to 90 daN/mmВ). The certification of TUV is referred to above given values of rail hardness.
