Product Introduction The hydraulic synchronous lifting transfer trolley is powered by battery. Two sets transfer trolleys can work simultaneously or independently, and can lift 30T material at the same time. The synchronous lifting error of two track trolleys in the range of 350mm hydraulic device is less than or equal to 10mm, and the synchronous walking error of two sets transfer trolleys in the range of running distance is less than or equal to 100mm. This kind transfer trolley can move freely without the need of external power supply. It is easy to operate and lift freely. The two sets trolleys can lift the workpiece at the same time or lift the workpiece separately. The lifting height of the trolleys can be designed according to the size provided by customers.
