QY12 Truck Crane
◆The whole vehicle conforms to 48 standards of China National Compulsory Inspection. Width indicator lamps are installed at the front, middle and rear. Side protection fenders are fitted for the vehicle.
◆Equipped with Euro Ⅲ compliant SC8DK230Q3 engine.
◆A load weighing device equipped in operator's cab can display load lifting capacity and give a warning when overload occurs, ensuring the safety in lifting operation.
◆QY12 is a truck crane with hydraulic drive, full swing and telescopic boom, step-less speed variation for various operation mechanisms.
◆Well-equipped safety devices such as relief valve, hydraulic lock, hoist limit switch, working radius indicator and stabilizer.
◆Double H-shaped outriggers operated from both sides of the chassis are used for support and leveling of the vehicle.
◆Simple structure, light weight and good mobility.
◆3-section main telescopic boom and single cylinder for front support elevating.
◆Two-pump flow can be combined for the winch to improve working efficiency.
Jib is available for option. Main Technical Specifications

Note:
◆(1)The data in the table are the max.lifting capacity when the crane is set up on level and firm ground.
◆(2)The total rated lifting load in the table includes the weight of hook block and slings(Main hook block 145kg)
◆(3)The working radius in the table is the actual value including boom deflection under load. So lifting operation should be performed according to the working radius, in reference of lifting height. |
