Link-Belt launches all-new 300-ton lattice crawler crane
The 348 Series 2 comes with Cummins QSL 9 350 hp Tier 4 Final and Tier III engine options
Link-Belt Cranes has introduced an all-new 300-ton (273-mt) lattice crawler crane. The 348 Series 2 comes with Cummins QSL 9 350 hp Tier 4 Final and Tier III engine options, and and deliver power to a Kawasaki pump and motor package. New ultra-wide hoist drum laggings, an integral part of the drum itself, provide the standard 28 mm hoist rope an extra-large circumference, extending rope life and offering maximum line pull of 24,179 kg.
A new attachment on the 348 Series 2 allows the heavy duty boom top section to remain in place to transition from conventional mode to luffing configuration. The maximum heavy duty boom length is 91.4 m, and the maximum heavy duty jib combination is 73.1 m plus 42.7m. The maximum long range boom length is 108.2 m, and the maximum long range jib combination is 89.9 m plus 42.7 m. A maximum combination of 54.8 m of luffing boom and 73.1 m of luffing jib provides 128 m of attachment and a tip height of 127.7 m.
The crane operator is assisted by on-board high-resolution winch-view, rear-view, and non-cab side swing-view cameras to enhance jobsite visibility from within the cab. An audio-visual travel and swing alarm system alerts crew members on the ground when the crane swings or travels.
A new luffing jib transport package with lifting lugs simplifies and expedites luffer assembly. The rear post will scissor into place by means of alignment links. The transport package also comes assembled with nylon rope reeving to assist with initial luffing jib wire rope hoist reeving. Once the rear post is in working position, all luffing jib pendant connections are made and the luffer is ready to be raised for work. All assembly is done from the ground with no work at height exposure. The 348 Series 2 has a live mast cylinder for self-assembly and lattice extensions can be mixed and matched with existing conventional boom of 348 H5 models so you can use heavy duty, transition, and long range boom on the 348 Series 2.
First shipments of the new 348 Series 2 will begin fourth quarter 2018 following final testing in Lexington, Kentucky.
