May 21, 2019 — LineWise introduced its new TLL-500A triple line lifter for subtransmission applications.
The new product is designed to be a low-cost, lightweight solution for supporting three phases of energized conductors between 34.5 kV to 72.5 kV. The four main components of the TLL-500A are easy to assemble on the jobsite. The steel mast, which contains a turntable that allows it to swivel up to 15° left or right, quickly pins to digger derrick adapters. The heavy-duty steel cross arm includes wear pads for maximum durability.
Aluminum extension arms allow adjustment of the polymer insulators in 3-in. increments from a minimum overall span of 7 ft., 4 in. to a maximum span of 16 ft. Insulators can be spaced a minimum of 3 ft., 8 in. apart or a maximum of 8 ft. apart.
The TLL-500A can be used in a horizontal or vertical configuration. It supports a maximum load of 500 lbs per position with a maximum side load of 200 lbs per position. An optional Delta configuration allows operators to hang insulators in a downward position from the insulator sliders. Insulator extender attachments can extend insulators to accommodate pole structures with one conductor that is higher than the rest. A static arm attachment is also available to pick the static line at the same time as the conductors.
The TLL-500A comes in a convenient skid container that allows forklift loading from any side and will fit into standard full-size pickup beds.
