TLL-300D
The Triple Line Lifter 300D is a multi-phase conductor support for distribution work up to 34.5kV. When your job demands wider phase spacing or vertical/horizontal orientation flexibility, the TLL-300D provides the muscle. Built to pin into a custom digger derrick or crane adapter, it keeps power lines securely supported during pole changeouts and structural maintenance without disrupting power to consumers.

- Digger Derrick & Crane Compatibility: Built with heavy-duty adapters to mount securely to digger derricks or auxiliary cranes, maximizing the utility of your heavy fleet assets.
- Dual Orientation (Horizontal & Vertical): Unlike standard jib-mounted lifters, the TLL-300D is engineered to be configured for both horizontally and vertically oriented phase layouts, offering maximum tactical flexibility on complex right-of-ways.
- Expanded Spacing Profile: Built for broader footprints, offering a wide maximum outside-to-outside phase spacing of 9′ 7″ (2921 mm), and a minimum of 1′ 7″ (483 mm), allowing crews to handle larger phase spans safely.
- Rotational Versatility: Crossarm pins directly to the fiberglass mast and can manually rotate 15° in either direction (both inline with the boom and 90° perpendicular to it) to align perfectly with uneven poles. This rotation is designed for the balanced, horizontal configuration only.
- No Tools, 10-Minute Setup: Engineered for high efficiency in the field. Two linemen can have the assembly fully deployed from the truck to the air in under 10 minutes.
- Crossarm & mast are composed of fiberglass for di-electric properties
- Fiberglass is sealed using LineWise desiccant canister system
- No cross bracing required
- 2 wire holder options:
- Roller Wire Holder
- Swing Gate Wire Holder
- 300 lb (136 kg) downward load
- 100 lb (45 kg) side & gate load
