All-terrain cranes have significantly made their presence felt in several areas-infrastructure, energy sector, and high-rise construction including maintenance due to their impeccable performance. Its versatility has always inspired manufacturers to develop more efficient All-terrain cranes to fulfill increasing demands of a wide range of markets while keeping in mind various road regulations around the world.
Recently, some of the industry leaders have introduced high-end technology driven designs of All-terrain cranes promising enhanced performance. Read on to find out about these designs and their capabilities.
The latest All-terrain crane from the house of Tadano—the biggest Japan-based manufacturer of cranes and aerial work platforms—is the ATF 600G-8. Loaded with an advanced Triple-Boom System, ATF 600G-8 has three telescopic tubes for increased torsional stiffness and transport efficiency, making the overall system much stable. This eight-axle model has a 600-tonne capacity, a 15.3 to 56 m boom, 24 to 90 m boom extension and maximum working radius of 104 m. This unit is also equipped with an asymmetric outrigger base control and the Hello-Net fleet management system.
More details:
• Two Mercedes Benz Euromot 4/Tier IV Final engines
• A 460 kW (626 HP) unit is in the carrier
• A 260 kW (354 HP) engine in the superstructure
Manitowoc—an American company offering products for the food service and construction sectors—has launched Grove GMK5250L having 250-tonne capacity. This five-axle model features a 70 m main boom, VIAB turbo clutch and Grove’s Megaform shaping for improved stability and strength.
Liebherr—a Swiss equipment manufacturer—has introduced its 250-tonne capacity all-terrain crane, LTM 1250-5.1. This is a powerful axle mobile crane loaded with VarioBase variable outrigger system and an Eco mode that makes it fuel efficient.
More details:
• Lattice extensions can increase hook height to 110 m.
• A 50 m fixed jib is available and the 12.2 to 22 m folding jib can be extended in 7 m sections to 36 m.
• Hydraulic adjustment can be done up to 45 degrees under full load.
• It is equipped with VarioBallast—a new feature which allows operation with two ballast radii, of 5.58 m or 4.78 m. The ballast radius can be minimized by 800 mm using mechanically swiveling ballasting cylinders to get operations in confined spaces done. Maximum ballast is 88 tonnes with a maximum width of 6.3 m. The 1 tonne base plate and the next 10 tonne ballast plate are the same width as the vehicle. Width is 4.1 m with up to 68 tonnes of ballast.
• A 400 kW six-cylinder Liebherr diesel engine is in the carrier to Stage IV/Tier 4f emissions regulations, which is driven by a 12-speed ZF AS-Tronic automated manual gearbox.
• A two-stage low range gear is there for low speed maneuvering.
• An intarder is integrated in the gearbox for braking. (Telma eddy current brake is optional)
• The hydraulic pumps in the superstructure are powered by a mechanical shaft from the engine in the carrier below, ensuring efficient crane operations.
