Crane arm for precise positioning of the welding device to the welding point. Precise positioning is significantly reduced in the preparatory phase before the welding process.
1. Load-carrying capacity 4 tonn.
2. A corner of turn of the lift in a horizontal plane, hailstones - ± 45;
3. Changes of a start of sliding section of the hydraulic lift, mm - 0-1000;
4. The lift has a rotary platform;
4.1 In the combined condition the lift puts welding head «on itself», that is on this platform;
5. The lift provides removal welding machine from the platform and lowering weding devices so, that a bottom edge of this device on 150-200 mm below level of a sole of a rail (provided that at present the chassis is on a Ry course).
