The Light Source Mega-Truss Dolly for two 11.4375-inch Global Truss sections is a specialized transportation cart engineered for efficient and accessible handling of this industry-standard truss profile, with the key feature of Mega-Couplers attached to the outside of the dolly frame. Its silver powder-coated steel construction provides durable protection against the wear and tear of touring and warehouse use. This outward-facing coupler placement is a deliberate design choice that prioritizes ease of access and rapid workflow. It allows crew members to easily see, reach, and operate the couplers for linking truss sections directly on the dolly or for connecting multiple dollies together, which significantly streamlines the assembly process during ground-rigging. The dolly's frame is precisely contoured with cradles to securely hold two truss segments parallel to each other, preventing rolling and shifting during transit, while the external couplers remain fully accessible and are protected from ground impact by the dolly's overall structure.

The dolly's robust construction is based on welded steel tubing, designed to handle the weight and dynamic loads of moving loaded truss. It is equipped with four heavy-duty swivel casters, typically with locking brakes, to provide smooth maneuverability over uneven floors and sufficient load capacity. The external coupler configuration means the truss is loaded with its connection points facing outward. This can greatly expedite the process of building long truss lines, as crews can couple ends together without unloading the truss from the dollies. While this design offers slightly less lateral protection for the couplers during tight maneuvers compared to inward-facing designs, the trade-off is significantly improved accessibility and workflow speed, which is highly valued in fast-paced production environments. The low-profile design ensures a stable center of gravity for safe movement.

This dolly with external couplers offers distinct logistical advantages for production companies and rental houses that prioritize speed and simplicity. It is ideal for situations where truss needs to be frequently connected and disconnected on the show floor, such as during the assembly of large overhead grids or when using a "build-on-the-dolly" approach. It enables efficient ground-rigging, as technicians can attach fixtures and cabling to the truss while it is secured on the dolly and then quickly couple multiple dolly loads together to form longer sections before flying. For warehouse operations, the external couplers make visual inspection for damage quick and easy. This design exemplifies a practical solution that balances coupler protection with operational efficiency, making it a valuable tool for handling Global Truss in dynamic event production settings.
