The Light Source Mega-Truss Dolly is a versatile and robust transportation cart engineered to securely handle two distinct truss configurations, maximizing utility within a production or rental inventory. Its silver powder-coated steel construction provides durable protection against the wear and tear of frequent loading and transport. This dolly is uniquely designed to accommodate either two sections of 12-inch diameter truss or a single, larger 20.5-inch diameter truss segment, with the critical design feature of Mega-Couplers being attached to the inside of the dolly frame. This inward-facing coupler placement is a deliberate engineering choice that protects the valuable couplers from lateral impacts during movement and when navigating through doorways or tight backstage areas. The dolly's frame is contoured with specific cradles to securely hold the chosen truss configuration, preventing rolling and shifting, and ensuring the truss and its couplers remain undamaged.

The adaptability of this dolly lies in its intelligent frame geometry. For the two 12-inch truss setup, the cradles are positioned to hold the truss sections parallel and stable. When configured for a single 20.5-inch truss, the frame utilizes a different set of supports to center and secure the larger, heavier load. The inward mounting of the Mega-Couplers means the truss is loaded with its connection points facing the interior of the cart, shielding them from direct contact with walls, other equipment, or the ground. This design philosophy prioritizes equipment longevity. The dolly is equipped with four heavy-duty, swivel casters—often with locking brakes—that provide smooth mobility over uneven floors and the strength to support the substantial weight of the truss and any pre-rigged equipment.

This dual-purpose dolly offers significant logistical and economic advantages for staging companies, rental houses, and touring crews. It simplifies inventory management by serving multiple truss types, reducing the number of specialized carts needed. The inward coupler protection directly translates to lower maintenance costs and fewer repairs for the expensive coupler hardware. In practice, it enables efficient ground-rigging; crews can pre-assemble lighting or speaker arrays onto the truss on the dolly and then wheel the entire unit into position for flying. This workflow enhances safety by minimizing overhead work and drastically accelerates load-in and load-out times. By safeguarding critical connection points and offering flexible configuration, this dolly is an essential tool for maintaining an efficient, professional, and damage-free workflow in the fast-paced environment of event production.
