Telescopic Crawler Cranes in Transmission Line Construction

Chain Electric Company and Scott Powerline deployed a Tadano's 60-ton telescopic crawler crane to streamline heavy lifting during high-voltage utility infrastructure construction.  www.tadano.com Chain Electric Company partnered with equipment supplier Scott Powerline and Utility Equipment to integrate a 60-ton telescopic crawler crane into the installation of eight miles of 230 kV electric transmission towers outside Meridian, Mississippi. The infrastructure project supplies high-voltage power to a regional data center, requiring machinery capable of handling dual-hook lifting operations across irregular terrain without supplementary support machinery. Operational Challenge and Partner Roles Constructing 230 kV transmission lines requires lifting heavy poles, mounting cross-arms, and executing wire picks on unpaved ground. Traditional crane configurations require multiple transport trucks, disassembly, and flat assembly surfaces, leading to logistical delays and increased site congestion. To address these site constraints, Scott Powerline supplied the Tadano GTC-600-2 teleboom crawler to Chain Electric Company. The equipment deployment consolidated several heavy-lifting phases into a single continuous workflow, eliminating the need for secondary support machines to erect structural components. Technical Specifications and Machine Architecture The machine features a 113.8-foot full-power boom, an 85% gradeability rating, high ground clearance, and extendable tracks for navigating steep inclines and unpaved terrain. The system operates using a closed-loop hydrostatic drive to maintain fine control during structural placement. Dual winches with 16 mm wire rope enable dual-hook operation using an auxiliary nose sheave or jib, allowing single-machine handling of both pole erection and cross-arm installation. Operational monitoring relies on the AML-C rated capacity indicator, which dynamically adjusts load charts to slopes of 0.5, 1.5, 2.5, and 4 degrees based on real-time machine orientation. Operators can pre-program spatial constraints for swing angle, height, and radius, which trigger automatic soft stops to prevent interference with surrounding infrastructure. Site Implementation and Logistical Impact During field operations in Mississippi, the teleboom crawler completed structural framing, component setting, and conductor rigging within muddy corridor conditions. The unit allows full pick-and-carry lifting capabilities up to 4 degrees out of level, avoiding ground re-leveling procedures before positioning each transmission tower. From a logistics standpoint, the crane requires only a single transport trailer for transit without counterweight breakdown or boom disassembly. This mechanical footprint reduced mobilization time and haulage costs between utility corridors. Technical field support and parts availability were coordinated directly between Scott Powerline and the manufacturer to maintain uptime throughout the transmission build.
