History In 1970, Goldhofer developed the first modular heavy-duty systems. In 1988, the first self-propelled modular transporter with hydrostatic drive was built. In 1989, Goldhofer introduced the electronically synchronised steering. In 1993, further development of the electronic multi-way steering for self-propelled modules.

Heavy-Duty Modules

Heavy-duty modules of Goldhofer are an extremely flexible and economical transport system to solve any transportation task for payloads ranging from approx. 70 tons to over 10,000 tons. Additional equipment such as goose-necks, pulling devices, loading bridges, long load equipment, etc. ensure an optimum adaptation to load and transport route requirements.

The advantages of the heavy duty modules - Pendular axles with hydraulic axle suspension system (levelling) - Hydro-mechanical all-wheel force-steering in 2-circuit execution - Center beam in box-section design with extremely high bending strength - Air reservoirs, hydraulic oil reservoirs and steering system integrated in the bogie frame and thus protected against damage - Optimised bolt-plate couplings for easy coupling of the modules - Combination possibility in longitudinal and lateral direction - Various expansion possibilities by means of additional equipment (see page 9) - Suitable for combination with commercial heavy-duty tractors - Directly combinable with hydraulically driven combination modules of series PST and PST-E

Frame The center beam in box-section design with strong cross beams guarantees a high frame strength and thus optimum load characteristics. Air reservoirs, hydraulic oil reservoirs as well as the steering system are integrated in the bogie frame and protected against damage and corrosion. Modules with tyres in single arrangement and fitted with pivot bearings are also available with a recess for vessels in addition to the platform version.

Axle suspension and levelling The hydraulic axle suspension of the pendular axles of a vehicle is interconnected to hydraulic circuits (3- or 4-point ). Within these circuits an equal axle load is achieved. The hydraulic stroke of up to +/- 300 mm enables optimum compensation in longitudinal and lateral direction and therefore permits operations on uneven terrain as well as the adjustment of extreme side tilt (levelling).

Steering The heavy-duty modules are equipped with hydro-mechanical all-wheel force steering in 2-circuit execution. This feature is advantageous inasmuch as the full steerability is maintained, should one of the steering circuits possibly fail. The steering angle on modules with pivot bearings is 60°, whereas modules with ball bearing race rings feature a steering angle of 55°. Adjustment of the steering combinations is made by changing the steering points of the track rods. The track rods are easily accessible from above. The electronic steering synchronisation enables a central turning point independently of the position of the modules.

Combination Possibilities / Variants

For large loads with a high centre of gravity, several platform trailers can be combined in longitudinal and lateral direction. Longitudinal combinations Combination of modules in any configuration in longitudinal direction Parallel combinations Combination of modules coupled side by side to reach a vehicle with 11/2 - or 2-module widths. In the “split” version (for 11/2 module width), the modules are split lengthwise, thus resulting in a platform combination with three pendular axles per axle line.

Goose-necks - Universal goose-neck to combine bogies or loading decks with claw coupling without an adapter - Combination goose-neck to combine bogies and intermediate platforms. The coupling of loading decks with claw coupling requires an additional adapter.

Loading decks Intermediate platforms Crawler decks - Single extendible - Foldable side extensions Drop decks - Single extendible - Foldable / telescopic side extensions

Off-Shore For off-shore operation, the efficiency of the heavy duty modules becomes apparent. All operations such as loading, transporting, positioning and unloading are carried out by the heavy-duty combinations. Also parallel combinations with 3 or 4 bogies coupled side by side are used.

Especially suitable for off-shore operation are the self-propelled heavy-duty modules of the Goldhofer PST/E range. (See page 12). Long load equipment The long load equipment connects the bogies with the self-ing load or with the vessel bridges, resp. high girder bridges. The long load equipment is ed on ball and socket ts and sliding shoes on the bogies.

Heavy-Duty Transporters with Hydrostatic Drive

PST

Self-propelled transporters of the PST-range can also be combined with the conventional THP-modules in both longitudinal and lateral direction.

For the transport of super heavy loads, Goldhofer offers self-propelled heavy-duty transporters with hydrostatic drive. The hydrostatic drive ensures a smooth and jerk-free driving, even under arduous conditions. The tractive force and the driving speed mainly depend on the number of driven axle lines as well as on the output of the power pack. Major utilization of the self-propelled heavy-duty modules of Goldhofer is in the off-shore field as well as in power stations and plant industry. They are not only used for transportation including loading and unloading but also for exact positioning of large and heavy loads.

PST-E PST-E The self-propelled transporters of the PST-E-range have an electronic multi-way steering with a steering angle of /+/- 110°. This steering is used in individual modules as well as in any large longitudinal or lateral combination. The selection of the following steering modes as ∙ Normal driving ∙ 90° crab steering ∙ Diagonal crab steering ∙ Carrousel steering is push-button controlled through remote steering. The track rods do not have to be rearranged in this case as control of every axle is by means of sensor and hydraulic cylinder. The self-propelled modules can be combined with conventional THP-modules by adjusting the steering angle of the modular transporter to the steering of the conventional THP-unit using sensors.
