introduction：Crane safety device to prevent outdoor crane from sliding along the track under strong winds。A clamp attached to the bottom structure of the crane is usually used，Clamp the two sides of the track head to prevent coasting。The rail clamp is divided into two types: dynamic and electric（See picture[Structure of crane rail clamp]）。The manual rail clamp is generally screw type，Simple structure，But the clamping force is small、Move slowly，It is mainly used on small and medium-sized or temporary cranes with small windproof area。Large cranes or port cranes mainly use electric rail clamps。It is made by a heavy hammer through a lever or by a spring force to make the clamp clamp the track，With the oil in the hydraulic system

introduction：1．Selection of positioning datum (1)The selection principle of fine benchmark ① Datum coincidence principle。To avoid reference coincidence error，Easy to program，The design basis should be selected as the positioning basis，And make the design benchmark、Positioning reference、Programming origin three unified，This is the best consideration。Because when the machining surface positioning datum and design datum do not coincide，And the processing surface and the design basis are not processed at the same time in one installation，Reference coincidence error will occur。 ②Datum unification principle。In multiple processes or multiple installations，Use the same positioning reference，In this way, the mutual position between the machined surfaces can be ensured
