Link-Belt All Terrain Cranes

HOLT Crane & Equipment is pleased to announce that Link-Belt has expanded its all terrain crane offerings with the new 250-ton (220 mt) ATC-3250. Piling on serious lift to an already potent product line, this new crane combines all the job-proven attributes of the ATC-3200 with even more muscle.

Long Reach. The ATC-3250 is equipped with a 43.3–223.1-ft (13.2–68.0 m), full power, seven-section, latching boom. The sections extend independently by means of one double acting, single stage hydraulic cylinder. Four pinned positions of 0%, 46%, 92%, and 100% on each section provide thirty-eight extend combinations for superior capacities when varying the extensions of the telescoping sections.

A 17.7–43.3-ft (5.4–13.2 m) two-piece, lattice fly and four lattice fly extensions are available as options for additional reach. Each of the extensions is 19.7 ft (6.0 m) and extends the fly length to 63 ft (19.2 m), 82.7 ft (25.2 m), 102.4 ft (31.2 m), and 122.1 ft (37.2 m). All of these attachment combinations have offset positions of 0, 20, and 40 degrees. The 43.3-ft (13.2 m) attachment with all four lattice extensions used in combination with the main boom reaches a maximum tip height of 358 ft (109.1 m).

Strength with Finesse. The ATC-3250 features the job-proven LoadCom load radius compensating system. Given the inevitable boom deflection under load, operators have to precisely adjust the boom elevation and winch to keep a load from drifting out. On the 3250, the LoadCom feature eliminates the guesswork. As a load lifts, the LoadCom system automatically compensates for this boom deflection by activating the boom hoist.

Worthwhile Winches. Axial piston, constant displacement motors with final layer and third wrap indicators drive the main (front) and auxiliary (rear) winches. The main and auxiliary grooved hoist drums contain 1,148 ft (350 m) of 0.83 in (21 mm) wire rope. Maximum line pull for each winch is a powerful 24,504 lbs (11 114.8 kg) and the maximum line speed is 508 ft/min (154.7 m/min).

Free Swing or Automatic Braking Mode. The variable swing brake system on the ATC-3250 gives the operator great flexibility. In free swing mode, the operator can simply return the control lever to neutral or gradually reverse the direction of the swing control lever to bring the upper to a smooth stop. In automatic brake mode, the upper will automatically stop when the controller returns to the neutral position. Swing speed is 1.8 rpm.

Agility Comes Standard. All terrain cranes must be highly mobile. The ATC-3250 sets the market pace for power and mobility. A 530 horsepower (390 kW) Mercedes-Benz engine and ZF AS-Tronic automated, 16-speed manual transmission deliver a top speed of 52.8 mph (85.0 km/hr). With five axles, the ATC-3250 features a 10x8x8 drive/steer configuration. This combination of power and traction allows the 3250 to tackle 61% grades. Also, a third axle lift system is incorporated that provides more inter-bridge spacing to comply with certain transportation requirements found throughout North America.

Many Standard Features. The ATC-3250 has a long list of standard features like:

An automatic outrigger leveling system
One touch outrigger deployment
Central lubrication for carrier and upper structure
Air and electrical connections for a boom dolly or trailer
A free swing and boom hoist float for transporting the boom over the rear with a boom dolly
Meets SAE structural and stability requirements.
The new 250-ton (220 mt) ATC-3250 piles on performance to Link-Belt's ATC line.
