900 ton girder lifter TT900 wheel precast girder gantry cranes lifting machine.
XCMG TT900 precast girder gantry cranes is designed and manufactured in response to the construction characteristics and requirements of high-tonnage prestressed concrete box girders for China’s dedicated passenger railways.
It’s applicable for the in-site handling and installation of 32m, 24m, and 10m full-span box girders for 250~350km/h dedicated passenger railways.
It works with the girder transporter to complete the installation of full-span concrete box girders.
Performance Characteristics:
1.With double-girder double-gantry tower outrigger structure, the girder transporter can directly drive into the machine belly for transportation of girders.
2.The wheeled full-hydraulic drive can realize the longitudinal, lateral, and inclined traveling and small-angle steering, featuring high flexibility and mobility.
3.With lifting height up to 12.5m, it can realize simultaneously lifting of one girder and transportation of two girders, featuring small occupation area.
4.The lifting system can realize four-point lifting and three-point balancing to prevent the distortion of girder body.
5.This machine real-time monitors the running parameters and incorporates the over-limit warning and emergency locking functions, including the load over-limit, steering error over-limit, and machine off-tracking.
6.The electric system adopts CAN-BUS control to realize the remote malfunction checking and diagnosis functions and improve the malfunction troubleshooting efficiency.
