Terex's Newest Crawler Crane, the LC 330US, Meets Heavy Civil Work Needs
October 27, 2016 – Terex Cranes has introduced the LC 330US lattice-boom crawler crane, the largest crawler in this product range. With a 330-ton lifting capacity and 2,000-ton maximum load moment, the crawler offers contractors high lift capacities in a design that is efficiently transported to the project site and quickly ready for work. The crane is ideal for contractors operating in the heavy civil infrastructure, such as bridge construction, and working in energy sectors.

“The new LC 330US crawler crane design grew out of our global product design and manufacturing strategy," says Guntram Jakobs, manager of product marketing for Terex Cranes. "Product engineering, manufacturing, and supply chain team members from our Jinan, China, and Zweibrücken, Germany, locations worked together throughout the product development process.” The new model will be manufactured in Terex's Jinan facility.
The LC 330US crawler crane has the Terex-exclusive counterweight tray design, which comprises two stacks on each side instead of a single stack. This reduces counterweight stack height, lowers the crane’s center of gravity with no need for central ballast, and improves counterweight assembly efficiency (the required lifting capacity of a 10-ton assist crane). Crew members can quickly adjust front/rear stack height to address counterweight needs based on boom configuration and according to the load charts.
The LC 330US crane’s crawler tracks will self-assemble to help achieve short setup time. It can be configured with up to 275 ft . of main boom or up to 196 ft. of main boom with a 236-ft. luffing jib for a total maximum system length of 432 ft. Standard assembly remote control increases rigging ease, and is equipped with the Terex fall protection system for safe boom assembly and disassembly. For further reduction of setup time and expense, the main boom can be rigged “free in the air” with up to a 177-ft. main boom without an assist crane.
Terex Cranes’ slide-in system for the main boom sections more efficiently utilizes truck payload to reduce transportation costs and time. Transported without restrictions on a standard lowboy or drop-deck trailer, the smaller boom sections are designed to easily be placed inside larger ones for moving to the project site. Lifting lugs located on the lower main cords of the boom section improve boom loading efficiency and reduce work at height. For making more efficient use of available ground space in congested sites, available stacking blocks provide safe, quick, and easy stacking of boom sections.
The LC 330US crane’s counterweight slabs are interchangeable with Terex and Demag lattice-boom cranes in operation since 1998 and Demag all-terrain crane models starting with the AC 500 and higher. Efficient maintenance intervals limit service time to increase crane utilization rates. The wide Terex cabin offers enough room to comfortably fit a second operator. Two operating screens – one displaying engine, winches and crane settings; and a second showing the IC-1 Load Moment Indicator – offer intuitive crane operation to improve operator’s productivity.
