History and service record of 1644 HIGH CAPACITY MODEL and 1 related model

  • Ownership. JLG was founded in 1969 in McConnellsburg, Pennsylvania, sold its first aerial work platform in 1970, operated independently until Oshkosh Corporation acquired it in late 2006, and is now an Oshkosh subsidiary that makes access equipment and telehandlers. JLG Industries, Wikipedia.
  • Production. LECTURA Specs lists the JLG 1644 as built from 2019, other sources from 2018 at McConnellsburg, Pennsylvania; it lifts 15,650 lb to 43 ft 7 in with a 31 ft 1 in reach, on a Deutz TCD 3.6 L diesel. JLG 1644 telehandler (2019-2026), LECTURA Specs; JLG 1644 high-capacity telehandler, JLG.
  • Spec sheet. A rental spec sheet for the 1644 gives 6,750 lb at maximum lift height. JLG 1644 spec sheet, For Construction Pros.
  • SmartLoad Technology. JLG's 1644 announcement describes SmartLoad as three technologies: attachment recognition that shows the right load chart, a load management information system that shows where the load sits on the chart, and a load stability indicator that limits operation near maximum capacity. JLG Showcases 1644 High-capacity Telehandler, For Construction Pros.
  • 1644 working figures. JLG lists a 15,650 lb rated capacity, 43 ft 7 in maximum lift height, 31 ft 1 in maximum reach, 6,750 lb at maximum height and 2,000 lb at maximum reach. JLG 1644 High-Capacity Telehandler, JLG.
  • Attachments. Listed 1644 attachments include a side-shift carriage with four inches of shift each way, a dual fork positioning carriage, a fork-mounted work platform, lifting hooks and a rotating coupler-mounted winch. JLG 1644 High-Capacity Telehandler, JLG.
  • Industries JLG names. JLG's high-capacity telehandler brochure names wind, oil and gas, steel erection, industrial construction and mining as industries with unique challenges these machines are built for, and adds that their ability to handle heavy bulky loads makes them suited to maintenance on other machines in the rental yard. High Capacity Telehandlers brochure, JLG.
  • Attachments for heavy work. JLG says its high-capacity attachments, from standard carriages to specialised tools for industrial construction, logging, mining and wind, are manufactured to the same quality as the machines they work with. High Capacity Telehandlers brochure, JLG.
