Working Principle
The Low Voltage rail transfer Car operates fully automatically by drawing power from low-voltage electrified rails, featuring a straightforward working mechanism and outstanding durability.
380V industrial power supplied to the workshop is first stepped down to safe 36V low voltage via an on-ground isolation transformer and transmitted to insulated rails. The cart obtains power through conductive wheels mounted on its base that make contact with the rails. An on-board electrical system then boosts the voltage to drive the travel motors.
Operators control start/stop, forward/reverse movement and speed adjustment via a pendant controller or wireless remote control. Power is supplied entirely through low-voltage rails without trailing cables. The cart enables stable cyclic transportation along fixed workshop routes, delivering superior safety and continuous operation performance.

Limitations of Low Voltage rail transfer Car
To assist customers with accurate model selection and avoid operational issues, the key application limitations of Low Voltage rail transfer Car are specified below:
Travel Distance Limitation
Voltage drop will occur during long-distance transportation. Supplementary copper busbars for voltage compensation or additional supporting transformers must be installed to guarantee stable equipment operation.
Power Supply Mode Limitation
Power supply solutions are clearly classified by load capacity. Heavy-duty models over 50 tons use three-phase low-voltage power supply, light-duty variants suit single-phase low-voltage power supply.

No fixed standard recess is adopted. Recess depth and curvature are engineered on-site based on customers’ cylindrical workpiece diameter and dead weight. This achieves tight fitting, eliminating shaking and loosening in transit for superior positioning performance.
Optional Anti-slip Structures
To address minor sliding risks of vertical cylindrical workpieces, anti-slip plates and positioning stoppers can be installed upon request. These fixtures firmly secure loads to prevent shifting and collisions, maximizing workpiece integrity and operational safety.
Flexible Optional Auxiliary Tooling
Hydraulic lifts and rotating platforms can be fitted to match production workflows. The cart supports processes including cylinder fitting, joint assembly and non-destructive testing. One unit meets transport demands across multiple procedures for greater versatility.
