Dual-rail Transport Robot

Dual-rail transport robot is a heavy-duty high-precision rail-guided automatic transfer equipment designed for automated production lines, CNC clusters, intelligent warehousing and multi-station assembly lines. It adopts a dual-rail parallel walking structure. Compared with single-rail RGV, it provides larger load capacity, higher stability and stronger docking precision.

This equipment is mainly used for cross-station automatic conveying of heavy workpieces, material frame tooling, whole-stack materials and machine tool groups. It can cooperate with truss manipulators, six-axis robotic arms, automated material silos and assembly lines to realize full-process unmanned transfer. It is widely used in mass-production, heavy-load and high-precision docking automated production scenarios.

Zhejiang Luban Automation Technology has mature technical accumulation in the field of heavy-duty RGV. The company holds multiple independent patents, and the technical team has full-process service capabilities from scheme design to on-site commissioning. Our dual-rail RGV products have been successfully applied in multiple heavy-duty automation projects.

In heavy-load automated production lines, transporting hundreds of kilograms of workpieces or material frames is one of the most difficult challenges. Manual carts cannot move them, forklifts are not flexible enough, and single-rail RGV may worry about insufficient load capacity and unstable operation.

Dual-rail RGV completely solves these problems through its dual-rail symmetric supporting structure. The vehicle body is evenly stressed with high rigidity, ensuring heavy-load operation without shaking, lateral swing or deviation. The dual-rail balanced load design significantly improves the overall load limit of the equipment, capable of carrying heavy metal workpieces, large tooling plates and whole-stack material frames.

A heavy-industry customer, after adopting dual-rail RGV, automated the heavy-workpiece handling work that originally required forklifts back and forth. Not only did they save two forklift operators, but transfer efficiency improved by more than 50 percent.

The cart walks back and forth along dual-rail tracks, adopting a dual-rail synchronous walking design. It uses servo drive and encoder closed-loop positioning system, with extremely small docking error. It automatically takes heavy-load materials from the pickup position, walks along the track to the target station for precise docking, and automatically returns after completing material handover.

The equipment is equipped with industrial PLC control system, supporting multi-station fixed-point docking, automatic call, automatic return, cyclic transfer, shortage standby and station avoidance intelligent logic. It supports dual-mode switching between high-speed empty travel and low-speed docking-empty travel quickly back and forth to improve efficiency, docking at low speed precisely to ensure accuracy.

The vehicle body uses thickened steel structure, with strong track rigidity, wear-resistant and deformation-resistant. The electrical system is dust-proof, iron-chip-proof and anti-interference.

The dual-rail parallel structure ensures even stress on the vehicle body, eliminating unilateral tilting and walking deviation. The track has strong rigidity, is wear-resistant and deformation-resistant, with no looseness during long-term high-load operation. Working temperature range is -10 to 45 degrees Celsius.

Safety features include front and rear infrared anti-collision, mechanical hard limit, electrical limit, overload protection, emergency stop, sound and light alarm and anti-falling anti-slip multi-protection.
