Link-Belt says it plans to introduce its 300 AT, an entirely new all-terrain crane platform, at the ConExpo-Con/Agg show coming up in Las Vegas from March 14th to 18th. The five-axle 300 AT will have a lift capacity of 300 tons (250 metric tons) and a maximum tip height of 369 feet (112 meters).

“We spoke extensively with our customer base and feel like we have delivered,” says Andrew Soper, Link-Belt product manager for Telescopic Truck and All-Terrain Cranes. “They want a crane that travels down the road efficiently, goes together on a jobsite quickly, has a strong chart, and is reliable. This crane represents Link-Belt’s long-term AT investment, which goes back to 2009 with construction of our own formed boom bay and subsequent ATC-3275 introduction.”

The Link-Belt 300 AT

The new Link-Belt 300 AT has a seven-section boom that can extend from 46 to 238 ft (13 to 72.5 m). The boom has a pin-and-latch telescoping system, greaseless sheaves, and Teflon wear pads. Other standard features include a wireless wind speed indicator, a rope guard with one-hand operation, and work lights at the base of the boom.

Options include a two-piece, 42- to 71-ft (12.8- to 21.6-m), onboard fly that can be hydraulically offset, as well as two 25-ft (7.6-m) lattice extensions. For placing precast wall panels and other two-load line jobs, Link-Belt offers an 8-ft (2.4-m) heavy lift fly with line separation. The manufacturer’s SmartFly system allows one person to easily erect or stow the fly in sequence with a minimal amount of work at height.

The 300 AT can be transported by itself with its 8,000-pound (3,628-kilogram) upper counterweight tray at 23,000 lbs (10,432 kg) per axle. Its maximum complement of 162,000 lbs (73,481 kg) of counterweight requires four overflow truckloads for transportation.

Single-Engine Design

The 300 AT uses a single, 554-horsepower (407-kilowatt) Cummins X15 engine. It can run on HVO fuel and is EPA On-Highway and CARB On-Road-compliant. The carrier’s transmission is a ZF Traxon automated manual with built-in intarder braking. Link-Belt says its improved shifting performance and paddle shifters make stop-and-go traffic much easier to navigate with the crane.

The carrier of the 300 AT borrows the 175 AT’s two-person cab with automatic climate control and an air ride seat with lumbar support. The carrier cab also offers Bluetooth radio, phone charging, and LED lights.

Upper Section

In the superstructure cab, visibility is enhanced by large sweeping wipers on the front and top windows, quick defrost vents, and a multi-camera Site Vision package. Link-Belt’s Pulse 2.0 control system is presented to the operator on a 10-inch touchscreen. The display also provide access to Link-Belt’s V-CALC (Variable Confined Area Lifting Capabilities) variable outrigger extension feature, which now offers more flexibility in maximizing lift capacity in tight quarters where full deployment of each outrigger is not an option.

Link-Belt also provides the 300 AT with a wireless remote to control the carrier and upper structure, as well as to erect the fly jib. The crane has a 24-volt electrical system with CAN bus device communications and a deluxe lighting package. The flat carrier deck has four access points, and each dedicated anchor point offers tie-offs to support various working positions. Other standard features include Link-Belt’s SmartStack counterweight detection system and tire pressure and temperature monitoring.
