Link-Belt upgrades the HC-278H II 300-ton Lattice Boom Truck Crane

LEXINGTON, Ky. (September 22, 2001) — Pat Collins, Senior Product Manager – Lattice Cranes, unveiled the upgraded HC-278H II 300-ton (277 mt) lattice boom truck crane during the SC&RA Workshop in Lexington. The machine upgrades include two-stage boom, additional counterweight and a luffing attachment.

The two-stage boom, using the new “JE” boom through the first 190-ft. (57.91 m) of the maximum 330-ft. (100.58 m), yields increased stability and strength. Areas of the lift chart improve up to 25%. The “JE” boom is common to the Link-Belt LS-278H lattice boom crawler crane.

The increased capacities are attributed, in part, to the addition of a 10,000 lbs. (4 536 kg.) upper counterweight. This addition brings the total machine counterweight to 134,700 lbs. (61 099 kg.) Not only does the additional counterweight increase the main boom lift charts, it is part of the standard counterweight configuration for the luffing attachment.

The HC-278H II is available with a new luffing attachment which adds more job application flexibility to the machine. The luffing boom is comprised of the conventional “JE” boom and features a maximum 200-ft. (60.96 m) luffing boom, 200-ft. (60.96 m) luffing jib and 30-ft. (9.14 m) fixed jib.

This combination produces a maximum working height of 477-ft. (145.39 m) and maximum working radius of 263-ft. (80.16 m). The luffing attachment is also common to the LS-278H, which also now offers a “Mid-fall” feature.
