Goldhofer FAKTOR 5 bridge beam structure Module component design
The complete bridge beam truck trailer is very large in size, Goldhofer designed it into an easy-to-remove assembly form, and all components are sized to follow the principle of using container transport. After the entire bridge beam truck is disassembled It only requires the use of two 20' and three 40' frame containers and three 40' containers to fully pack the components. It is very suitable for long-distance transshipment. This is economical and convenient for transportation companies that often migrate to overseas operations. It is self-evident.
Transport module
Based on the principle of best use of materials, the transport module directly uses Goldhofer's existing products, so that even if it is not used as a bridge beam transport vehicle, the transport module can still be used independently. The standard Huai is equipped with two groups of multi-axle transport modules to carry two ends of the bridge beam. Each group is made up of several THP modules connected in series, and is available in 12 to 20 axis specifications to meet different transportation needs.
The THP module, which is the core unit of the Goldhofer modular heavy-duty truck, is very powerful. It has different axis versions and can be combined in arbitrary strings and parallels. Each axis is composed of two sets of pendulum axles, and the compensating ability of the pendulum axles in the transverse and longitudinal directions enables them to freely handle rough roads. The hydraulic suspension system of the THP module can be manually adjusted freely. This feature is when loading and unloading. Particularly useful, it can be seen that the THP module is very similar to Scheuerle's IrterCombi module. Because the THP module itself does not have power, it needs to be provided by the outside world. Therefore, a pull rod/push device is installed at the front and rear of the two groups of modules at the front and rear to connect the two tractors to achieve the front pull top.
Bridge beam body
The components of the bridge beam body are very rich. When the FAKTOR 5 bridge beam transporter is of the elevated type, the main components are as follows.
One is a cantilever. A cantilever with a base is the most important component. It is responsible for the connection with the transport module and the control of the beam. At the bottom of the cantilever is a large rectangular base that can be easily attached to the carrying surface of the transport module. The connection between the cantilever and the base is not rigid. Instead, a stable and balanced system is adopted, that is, the two are supported by a cross-shaped four-point support. Each support point has a retractable hydraulic cylinder and is transported to avoid drastic changes in the road surface. The object brings about excessive acceleration impact. An accumulator (inner gas-filled body) is connected to each cylinder. The use of gas pressure balancing allows the hydraulic fluid to flow between the cylinder and the accumulator, thereby automatically adjusting the four cylinders. The position reaches a stable balance to reduce external impact.
The second is the main beam. The main beam is also the load beam, which is located in the middle area of ​​the bridge beam. It is projected outside the transport module. The length of the load area can be adjusted by combining different numbers of main beam components. The range can be up to 11 to 17 m, or even More. long.
Three on the beam. The auxiliary beam refers to the beam section directly above the transport module for connecting the cantilever and the main beam, and its length can also be adjusted by combining different numbers of sub beam components. In general, the length of the sub-beam depends on the length of the transport module, it is to ensure that the projection of the main beam does not fall on the transport module. 0 All the elder sisters of the beam are bolted (such as the cabinets 12, 14) for easy removal Equipment.
The fourth is the intelligent cross fastening system. It is composed of a plurality of retractable fastening rods. The fastening rods are cross-connected between the two side girders by bolts. When adjusting the width of the bridge girder, only the bolts that fix the telescopic length in the fastening rod are removed. The length of the rod can be automatically adjusted with the width change, and then the bolt for fixing can be inserted after completion. Because there are multiple angles between the fastening bar and the subframe, the stability of the beam can be ensured.
The fifth is the beam bracket. There are two brackets, which are respectively installed on the front and rear transport modules near the main beam. When the beams have not been installed or the height is reduced to a minimum, this bracket can serve as a support beam.
Sixth is the support guide wheel. It is only an auxiliary tool. It is only used for cargo loading and unloading. When the beam is not yet fully connected, it is installed under the main beam to support and guide the direction. Once the beam is closed, it will be removed.
Seven is a lanyard. There are a total of 4 groups of lanyards, 2 in each group, which are placed on the main beam. The lower end of each group of lanyards can be bolted together with the end of the inner tube of the bottom support. This way, it can be safely and safely completed. .
Eight is the bottom support. There are 2 groups, each consisting of two steel tubes with a rectangular cross-section inside and outside, which can be used internally and externally. When the two outer tubes start to support the transport under the support, when the bridge beam loads the cargo, as long as the inner tube is inserted into the outer tube, and the inner tube and the lanyard are fixed together, the loading is completed. .
Features
The FAKTOR 5 bridge beam transporter has a load-to-weight ratio of up to 5:1, thanks to the Goldhofer's superb mechanical design capabilities. Compared to the 1991 version, the beam frame looks more compact and lightweight, of course, with the material and welding. Advances in hydraulics and other technologies are inextricably linked. With the same load capacity and lighter weight, the cost of transportation will be lower. The different loads of the FAKTOR 5 bridge beam carriers can reach a maximum load of 350 to 650 t. This carrying capacity is sufficient for most transportation tasks.
Several groups of vertical hydraulic cylinders on the bridge beam can control the height of the beam, and the stroke range can reach 0~1.8m. This feature is very useful. It is not only used to load and unload cargo, but also can adjust the height at any time during transportation. Adapt to the external environment. When the proportion passes under the high-restricted highway bridge, the height can be adjusted so that the bottom of the cargo is almost close to the ground; or when the corners have to pass over certain obstacles with a certain height, the maximum 1.8m can be raised during cornering. Height becomes useful.
Several groups of hydraulic cylinders on the cantilever can adjust the width of the beam frame, ranging from 3 to 6.75m. In addition, the length of the load area can be changed by adjusting the number of main beam components. The FAKTOR5 bridge beam transporter has a large cargo size. Adaptability is super.
Loading process
The self-loading and handling characteristics of the bridge-type beam transporter is a major highlight. Here, an overhead type FAKTOR5 bridge-type beam transport vehicle is taken as an example to analyze the entire process of loading cargo in detail.
Before loading the goods, the bridge beam transporter must first arrive at the loading site. Such a huge size of the transport vehicle obviously will not be directly delivered to the site in a complete form when it is empty. If the distance is far or even across the sea, the best option is to disassemble the vehicle into components and use containerized transportation to the site. If the distance is short, you can first assemble the bridge girder into an empty vehicle. That is, the front and rear parts of the vehicle body are assembled to the state in which the auxiliary beam is in place. The auxiliary beam is supported by beam brackets. The main beam is temporarily not installed, and then the two tractors each pull the half of the body onto the road to the site. At this time, it is equivalent to the semi-mounted bridge beam being transported by a trailer trailer.
After arriving at the scene, it is assumed that the bridge beam transporter has been installed in a half-and-half installation state, and then the main beam is installed on the auxiliary beam of the front half body, and a support guide wheel is installed below the main beam. Then adjust the width of the front and rear beams to accommodate the width of the transport.
Next, one of the tractors is facing the side of the cargo on the rear half of the vehicle, and the opening is facing the cargo. The other puller 7 pulls the front half of the vehicle and adjusts the direction with the help of the supporting guide wheel. Slowly stepping forward and aiming the opening at the other side of the cargo, so that the main girder on the front half of the car gradually sets the cargo in the middle and moves closer to the rear half body. After fine adjustment, the front and rear body frames are finally closed together. , And bolted, the beam at this time has formed a whole, surrounded by the cargo, the support guide wheel mission has been completed and was removed.
The cargo before loading has been preliminarily supported by the outer tube of the bottom support member of the bridge beam transporter. It is the time to insert the two inner tubes into the outer tube. The inner tube is slightly longer than the outer tube and hangs on the main beam. The four groups of lanyards are bolted together with one end of the inner tube, and the cargo is loaded. As long as the hydraulic cylinders on the cantilever beams at both ends of the bridge beam raise the beam height, the cargo is “pulledâ€. Under the front and rear top of the two tractors, the Hercules "Porter" was on the road.
The entire loading process of the bridge-type beam transporter is quick and easy. No crane is required to lift the goods. The goods can be loaded and fixed simply by stopping at the place, which greatly improves the safety. The uninstallation process is just the opposite and will not be repeated here.
Different versions and versions of the FAKTOR 5 Bridge Beam Transporter
(1) Flexible forms
The strongman of FAKTOR 5 does not stop at these characteristics. Due to the modular design of its components, it can easily be extended to different forms.
German Man Truck with FAKTOR 5 Bridge Beam
By replacing the unsuitable main beam and sub beam components, the FAKTOR 5 can combine the four types of bridge beam carriers previously described. The standard form of FAKTOR 5 corresponds to an elevated bridge-type beam transporter, and replacing it with a Z-shaped beam frame assembly will become a concave bridge-type beam transport vehicle that bears directly on the upper part of the main beam; if it is in the previous form The lower part of the main girder is pre-mounted with a support frame, and it becomes a concave bridge type girder with a support frame at the bottom; and if the main girder is not installed at all, only the side of the auxiliary girder is equipped with a component that can fit the side load hole of the cargo. , it can be transformed into a clamp-type bridge beam transporter.
The multi-axle transport module that carries both ends of the bridge beam can also be varied, and the standard choice is the THP module described in the preceding description with the tractor, or the Goldhofer self-propelled transport vehicle PST. PST with power module, eliminating the front and rear tractors, so the vehicle can be shorter in length, and PST can be remotely operated, the flexibility of the steering control is also higher, for short-distance transport than the use of THP The module has more advantages.
(2) New version
The FAKTOR 5 Bridge Beam Transporter is still evolving, with customized versions depending on the customer's needs.
Goldhofer Delivers Next-Generation FAKTOR 5 Bridge Beam Transporter to KAHL
For example, the new-generation FAKTOR 5 bridge-type beam transport truck delivered to KAHL by Goldhofer is very different from the standard version in cantilever design. The height of the beam frame is increased to 0-2.145 m, and the height of the cargo is increased. Advantages; In addition, the cantilever base used to fix the transport module also adopts a modular design. The load-bearing area between the transport module and the cantilever can be increased by adding a side support frame to better share the load to the transport. Each axis of the module.
