TLL-1300 lifter boasts remote-control features

The new LineWise TLL-1300 Triple Line Lifter features remote-controlled hydraulic articulation and hydraulic extension and retraction of the outside phases.
Designed to simplify and shorten the process of supporting three phases of energized conductors, the new LineWise TLL-1300 Triple Line Lifter features remote-controlled hydraulic articulation and hydraulic extension and retraction of the outside phases. Using the remote control, the unit can switch from a horizontal to vertical configuration, and the spacing between insulators can be adjusted from 6.5 feet to 14.5 feet to capture the outer conductors. Compared with current methods, reports from the field are showing the TLL-1300 can do the same job in up to 50 percent less time.
The TLL-1300 is powered by a separate ground-level hydraulic power unit featuring a 10-horsepower diesel engine. Insulated hoses run from the power unit to the crane boom up to the line lifter. If preferred, one can power the lifter utilizing the crane or boom truck’s hydraulics instead of the hydraulic power unit. With either option, the end-user achieves more reliable, responsive control.
Constructed of high-strength steel, the maximum capacity for the TLL-1300 is 1,300 pounds per conductor, or 3,900 pounds overall. The unit features holding valves on all cylinders and a manual override control valve.
Because safety is always a concern when dealing with energized lines, insulators on the unit are constructed of fiberglass and sealed. A desiccant canister is installed inside each insulator to monitor moisture. Insulators may be tested like a hot stick.
