What Load King does
Load King LLC, founded in 1956 and headquartered in Elk Point, South Dakota, is a manufacturer of vocational trailers and heavy equipment serving infrastructure-related industries across North America. Since 2015 the company has operated as a wholly-owned subsidiary of Custom Truck One Source (NYSE: CTOS), a specialty equipment provider whose network spans nearly 40 locations, a rental fleet of more than 10,400 units, and more than 2,500 employees as of 2024. Load King's end markets include electric utility, telecommunications, railroad, construction, forestry, and refuse/environmental services customers that use its equipment for transmission and distribution maintenance, network installation, rail maintenance-of-way, material hauling, and field service operations.
The company's product portfolio covers Stinger boom trucks with 10–80 ton lifting capacity and boom lengths up to 160 feet, Voyager service bodies (I, II, P, AMX, and AMX+ variants), Outback tracked bucket trucks and digger derricks, Lightning PTO electronic power take-off systems (U.S. Patent 11,691,508), dump trucks from 10 to 20 feet, water trucks from 2,000 to 4,000 gallons, chip trucks, rail bodies, roofing conveyors co-developed with Richmond Conveyors, and a complete trailer line including the 1966-patented E-Z Fold Mechanical Folding Gooseneck. Load King's proprietary Lightning PTO allows truck engines to remain off during stationary hydraulic operation, delivering up to 2,000 gallons of annual diesel fuel savings, up to 44.6 tons of CO2 emissions reduction, 85% noise reduction versus conventional PTOs, and reduced maintenance costs. The 2019 acquisition of Terex Corporation's boom truck, crossover, and truck crane product lines substantially expanded the company's crane and lifting offering, and integrations with Terex, Versalift, Altec, Peterbilt, and Battle Motors position Lightning PTO as the electrification layer for utility and vocational fleets.
Load King generates revenue across five streams: new equipment sales, equipment rentals, parts and aftermarket, service and warranty, and financing through Custom Truck Capital. The company employs 101–250 people and reaches customers through a multi-channel distribution model that combines a world-class dealer network across the US and Canada, the CTOS direct sales and rental footprint, authorized service centers (ALL Crane, Terex Service Centers, ACERES, ML Utilities, Stevenson Crane), and the CTOS online Marketplace for new and pre-owned equipment. Pricing is quote-based for new equipment sales, monthly for rentals, and pay-as-you-go for pre-owned units, with all transactions oriented toward enterprise fleet operators in capital-intensive infrastructure verticals.
