Underfloor Lifting Systems Lift and Lower Locomotives and Railcars

Singapore customers use our underfloor lifting systems lift and lower locomotives and railcars. The underfloor lifting systems(in-ground lifting systems) are custom designed for lifting and lowering complete trains or single rail cars and locomotives for maintenance and repair work as well as for replacement of components. 

Our underfloor lifting systems H-configurations utilize acme thread screws, helical bevel gears and a common electrical 3-phase brake motor to enable the synchronous lifting and lowering movement between the individual hoist. The acme lead screws are protected with protection boots in the upper position. Limit switches are used for detecting stop and safety positions.
