Jining three stone 5 t crane, small crane, small crane product advantages: arm: Our selection of 70 manganese plate big arm, 70 manganese, high strength toughness, low alloy, increased arm strength, reduce its own weight. Its strength is three times more than Q235. High price per ton of 3,000 yuan. 1000T CNC bending machine using the company large submerged, increase the span to increase the use of mechanics from the weight and the fulcrum of the angle.
