55 Ton Construction Equipment Quy55 Crawler Crane From Top Brand

Main Parameter
It is a 4-cylinder in-line, water cooled, supercharging intercooled SC8D170.2G2B1 engine from Shangchai diesel, with rated output power of 125kw, rated revolution speed of 1800rpm and maximum output torque of 730n. M. Its emission comlies with the Euro. III standard.

You can also choose a 4 cylinder in-line, turbocharging intercooled and eletric jet SC8DK215Q3 engine from Shanghai Diesel, with rated output power of 158kw, rated speed of 2200rpm and maximum output torque of 823n. M. Its engine complies with the Euro III standard.


It consists of display, controller, sensor, etc.
It adopts full automatic LMI(Load Moment Indicator) from working parameter can stop actions in dangerous direction and give audio warning. The controller and the displayer communicate with each other through CAN bus techniqued, which makes a high reliability. Its combination with the conventional electrics realizes the crane's automatic control and greatly improves safety, reliability and efficiency of crane operation. The parameters such as engine speed of revolution, fuel consumption, engine oil pressure and engine working time, etc. Can be shown on the display.
