Whether onshore or offshore, wind power plants confront haulage companies with a number of challenges in view of the need to transport each component as economically as possible. Goldhofer Aktiengesellschaft of Memmingen, Germany, offers customers not only the perfect vehicle configuration for every job but also a complete package of vehicle technology, decades of know-how and professional project engineering.
The following Goldhofer vehicles are mainly used for transporting wind turbine components.
For transporting long rotor blades, Goldhofer has developed a fourfold extendable flatbed semitrailer by the name of Super Lift. With a maximum deck extension of 57,800 mm, Super Lift is capable of handling rotor blades of the latest generation up to a length of over 65 m. The Goldhofer Super Lift semitrailer can be used with 5-axle or 4-axle tractors and in the latter case with or without a single-axle dolly. That ensures that maximum permissible fifth-wheel load is not exceeded when transporting heavy rotor blades. The Goldhofer Super Lift offers haulage companies the ultimate in flexibility, optimum handling and maximum efficiency.
FTV 300 rotor blade transport device
With its new FTV 300 rotor blade transport device, Goldhofer has introduced a ground-breaking innovation for the transportation of rotor blades, which can now be trucked on twisting mountain roads with tight bends and over otherwise inaccessible terrain. The secret: Goldhofer’s FTV 300 holds the turbine blade at the hub connection and can tilt it up to an angle of 60° so that it is transported in a semi-upright rather than horizontal position. The FTV 300 is mounted either on a modular trailer or on a Goldhofer self-propelled modular transporter. Adapters are available to handle the various types of blades on the market and ballast elements to cope with differences in blade weight. So as to minimize the area exposed to wind in all phases of the journey, the pitch angle can be adjusted by rotating the blade around its axis to any position. The FTV 300 can be installed and removed without the use of a crane.
Transporting wind turbine hubs
For transporting turbine hubs, Goldhofer Aktiengesellschaft has a whole range of vehicles that are designed to take the weight. The normal solution will be to employ one of Goldhofer’s tried-and-tested drop-deck vehicles to ensure compliance with regulations for maximum load height, which is 4.2 m in most countries. Suitable vehicles include the STZ-VL with steering knuckle axles with pneumatic suspension, the MPA-V with McPherson independent suspension and the STZ-VP with pendular axles,
as well as heavy-duty modular trailers and self-propelled vehicles in the THP and PST series, which can be configured with various low-profile drop decks for the optimum solution for every hub and nacelle.
Goldhofer also offers a wide range of low loaders with various axle systems for transporting nacelles safely and efficiently. For nacelles with a weight of over 100 tons, the low loader semitrailers in Goldhofer’s STZ-P series as well as its heavy-duty modular trailers and self-propelled vehicles really come into their own.
Transporting tower sections
For transporting heavy tower sections, Goldhofer offers an ideal solution in the form of its new RA4 tower adapter, which can handle payloads of up to 180 tons. With the free-turning feature and the resulting high degree of flexibility, even the tightest bends and obstacles up to 3 m
high can be negotiated. That means all leading brands of tower segments can be transported without any problems.
Goldhofer is the world market leader for transport equipment in the field of general and heavy-duty road haulage and oversized cargo transportation. With a full and proven range of products, Goldhofer meets an extremely wide variety of needs in almost every transport situation. In a facility occupying about 100,000 square meters of grounds, the Goldhofer company has more than 600 employees producing perfectly engineered vehicles with payloads varying between 25 and 10,000 tons for demanding customers around the world. The history of Goldhofer Aktiengesellschaft goes back to 1705. In 2013 Goldhofer acquired Schopf Maschinenbau GmbH, thus further expanding its product portfolio in the fields of civil and military aviation and the mining industry.
