500t Multi-Alex-Trolley(FSM)

This hydraulic powered Multi-Axle-Trolley is used for transportation of Precast Full Span Girder. Trolley capacity is ranging from 300 ton up to 2000 Metric ton. MATs are custom made to suite the geometrical and capacity requirements of precast girder.

The trolley is self-motorized, by means of hydraulic motor reducer installed directly on the wheels therefore there will be no chain transmission involved.

Standard MATs are designed for longitudinal gradient of ±3% & Transverse gradient of ±3%. Larger gradient can be supplied upon request.

All wheel groups are steerable. The steering type is controlled by the PLC. The wheel groups are mounted on hydraulically driven slewing rings. Two endless screws connected to hydraulic motors activate the rotation of the slewing ring. One encoder registers the rotation of it and sends the data to the PLC. PLC controls the correct alignment of each wheel and there-fore the perfect steering with each wheel group on its own steering angle during the turning of the Trolley.
