Link-Belt announces new ATC-3130 II

Las Vegas, NV (March, 2005) — Link-Belt has upgraded its entry into the all terrain market with the introduction of the new ATC-3130 II, a 130 ton (117.9 mt) all terrain crane that will be on display at the CONEXPO-CON/AGG exposition in Las Vegas, March 14-19, 2005.

Long Reach Attachment

The ATC-3130 II is equipped with a new 42.7 - 170.6 ft (13.0 - 52.0 m) full power, five-section latching boom which extends each telescoping section independently by means of one double acting, single stage hydraulic cylinder.

A 31.2 - 53.1 ft (9.5 - 16.2 m) two-piece, telescoping lattice fly and two lattice fly extensions are available as options for additional reach. The first extension is 24.6 ft (7.5 m) and extends the fly length to 79.1 ft (24.1 m). The second extension is 19.7 ft (6.0 m) and extends the fly length to 98.8 ft (30.1 m). All of these attachment combinations have offset positions of 0, 20, and 35 degrees. The 53.1 ft (16.2 m) attachment with both extensions used in combination with the main boom achieves a maximum tip height of 278 ft (84.7 m).

Seat Capsule Tilts ... Not the Cab

The ATC-3130 II features an exclusive tilting operator’s seat capsule that operates separate from the cab structure. The seat capsule includes the seat, left and right control stands, floor and floor pedals, and the main console. All these components tilt together for better operator comfort when working the crane at high boom angles. This innovative system achieves the same goal as a conventional tilting cab, without all the hassles of securing personal effects every time the operator needs the tilting feature.

The cab has a sliding composite door, large tinted glass windows, and a hydraulically adjustable cushioned seat with a headrest. The controls and instrumentation are ergonomically designed and conveniently positioned, and display information in North American units of measure. Provisions to drive and steer the carrier for job-site travel and outrigger operations are also located in the operator’s cab.

The crane’s main operational controls are two electric-over-hydraulic, dual axis levers with fine metering capability for the winches, boom hoist, and swing. The main controllers, in conjunction with the rated capacity limiter (RCL), can also assemble and disassemble the modular counterweights.

Additional features are heating and air conditioning, a cabin pre-heater with a pre-settable timer, AM/FM stereo with CD player, power front window, floodlights, and an integrated cab walk.

Winches That Perform

The main and auxiliary winches are driven by axial piston, constant displacement motors with final layer and third wrap wire rope indicators. Both of the hoist drums are grooved and contain 820 ft (250m) of 21mm (0.83 in) wire rope. Maximum line pull for each winch is powerful at 21,010 lbs (9 530 kg) and the maximum line speed is 526 fpm (160.2 m/min).

Free Swing or Automatic Braking Mode

The variable swing brake system on the ATC-3130 II gives the operator the flexibility to bring the upper to a stop in different ways. In free swing mode, the operator can simply return the control lever to neutral and let the upper coast to a smooth stop or the operator can bring the upper to a stop by gradually reversing the direction of the swing control lever. In automatic brake mode the upper will automatically stop when the controller is returned to the neutral position. The swing speed is 1.7 rpm.

Mobility

The carrier performance is enhanced by a 517 horsepower (380 kW) Mercedes Benz engine and ZF AS-Tronic automated 16 speed manual transmission that delivers a top speed of 52.8 mph (85.0 km/hr). With five axles and a 25 ft 4 in (7.7 m) wheel base, the ATC-3130 II features a 10x8x8 drive/steer configuration with 20.5R25 tires. A third axle lift system is incorporated that provides more inter-bridge spacing to comply with certain transportation requirements found throughout North America.

The primary steering, controlled simply by turning the steering wheel, varies with the speed of the crane. Below 15.5mph (25 km/h) axles 1, 2, 4, and 5 steer in combination. As the speed of the crane increases, axle 5 and then axle 4 sequentially return to center until axle 1 and 2 become the only two axles steered. There are also five additional steering modes including independent front, combination, crab, independent rear, and a temporary crab steering mode. The temporary crab steering mode allows the crane to be driven away from an obstruction like a curb or a wall. The turning radius at the centerline of tire is a tight 29 ft 1 in (8.9m) and the overall turning radius for the entire crane is only 39 ft 11 in (12.2 m).

The carrier has other mobility conveniences like cruise control, engine compression brake, and a driveline intarder. The intarder is produced by ZF and is a hydrodynamic driveline brake that is integral to the transmission.

The suspension is a hydro-pneumatic system with automatic ride height leveling and level adjustment capabilities. With leveling adjustment, the crane can be tilted laterally and longitudinally by pushing a series of buttons in the carrier cab. This enables the operator to level the crane before deploying the outriggers to ensure the outriggers can be fully extended prior to raising the crane on its jacks.

The ATC-3130 II suspension is also designed to handle all 77,160 lbs (35 000 kg) of counterweight and the entire 98.8 ft (30.1 m) fly attachment when job-site travel is necessary.

Convenient Outrigger and Suspension Controls

New and innovative on the ATC-3130 II are the outrigger/suspension controls mounted on both sides of the carrier. These stations not only enable the operator to have full control of the outriggers and suspension, they also provide starting, stopping, and throttle control of the engine. Other features include deploying two outrigger beams at the same time, automatic leveling when the crane is up on its outrigger jacks, and one touch lowering of the outrigger jacks.

Loads of standard features

The ATC-3130 II all-terrain crane has a long list of additional features like central lubrication for carrier and upper structure, air and electrical connections for a boom dolly or trailer, integral boom dolly connections, free swing and boom hoist float for transporting the boom over the rear of the crane with a boom dolly, and, like all Link-Belt cranes, it’s been tested to meet SAE structural and stability requirements.
