Following last month's announcement that it has ended its supply agreement with Tadano, Link-Belt has revealed its North American-built 275-ton ATC-3275 all-terrain crane at ConExpo. The unit is manufactured by Link-Belt at its Lexington, Ky., plant, and according to the company, it is the first AT crane engineered with a focus on the North American market. Designed with customer input, the ATC-3275 will meet the transport laws in North America and Tier 4 interim and EPA 2010 on-highway requirements.
For transport, the ATC-3275 breaks new ground with its modular counterweight system. Weighing no more than 22,00 pounds each, the counterweights can be grouped together or with other components on transport trucks to maximize the loads. Maximum counterweight, rigging, matting, and fly extensions can move in four truckloads.
A Cummins EPA 2010 compliant engine provides power, and the anti-lock (ABS) disc brakes, intarder, and true engine compression brake allow the AT to meets SAE braking codes. Emergency steering, cruise control, traction control, and extra steering cylinders for maneuvering in difficult terrain are standard. The traction control has a mud and snow setting to allow more slip when needed. Also available is inter-axle and cross-axle differential locking. The military-grade, two-piece aluminum wheels require no special tools to service in the field. For operator comfort, the unit is equipped with Link-Belt's Hydrogas suspension system.
The ATC-3275's seven-section boom is fabricated from ultra-high-strength steel in Link-Belt's own facility. The two-plate design of each section has multiple longitudinal bends for superior strength. Teflon inserts keep the boom lubed and are universal for all boom sections. Eight boom modes maximize capacities by varying the extension of the sections.
Unlike other ATs, the 3275's upper engine mounts transversely to allow maximum space for the stowable fly. A 12-foot heavy-lift fly has lift procedures for two load lines. An optional three-piece bi-fold fly hydraulically offsets from 2 to 45°. A manual, four-position offset is available as well. Managing lifting functions (rated capacity limiter, boom telescope, etc.) will be a newly developed Link-Belt control system that will be unveiled at ConExpo.
All controls and buttons in both the upper and lower cabs are logically positioned, clearly marked with ISO symbols and within easy reach. The lower cab is single occupancy and features integral heating and air conditioning, multiple grab handles, heated and remote control mirrors and a six-way adjustable, air suspended seat. The upper cab tilts up to 20° to keep the operator comfortable at high boom angles. A swing-up roof window with windshield wiper and washer, engine-dependent warm water cab heating, a sun screen, cup holder, and a five-way-adjustable seat with headrest ensure a comfortable work environment.
All connections and service points are centralized and easily accessible, and the pressure for the hydraulic system in the upper can be checked at a single location. Large doors provide room to service both upper and lower engines, and every filter location is planned and designed for access. Available auto-lube systems (with manual overrides) in the upper and lower frames automatically lube at timed intervals.
