The wide range of low-loader trailers produced by Langendorf allows the fast and economic transport of construction vehicles on wheels and chains, finishers and milling machines, road rollers and operating platforms as well as containers. At the BAUMA Langendorf will present a vehicle of the SATH series in the open-space area FN 827/1.
The hydraulic platform in the low-bed is the specialty of the SATH low-loader trailer series. Thanks to very low ramp angles, vehicles with little ground clearance such as for example road finishers can be easily transported with these trailers. The whole loading bed has a length of 6,300 mm, 2,500 mm of which are lifted hydraulically by around 400 mm directly at the axle assembly. Due to this, there is the very low angle of less than 8° at the passage of the axle assembly into the loading bed.
The vehicle shown is extensively equipped. Despite the many options, a low empty weight of less than 15,000 kg could be achieved. All three axles are hydraulically steered and can additionally also be steered by means of a radio remote control as maneuvering steering. An ECAS Smart-Board with lift and lower function and the automatic driving height control from 30 km/h on complete the chassis.
A further highlight is the neck to be adjusted hydraulically, which can take a one-axle dolly additionally by this. Therefore, a fifth wheel load on the dolly of up to 25 tons is possible without exceeding the permissible axle load of the tractor.
The structure has rubber metal layers on all ramp slopes. The rest of the floor is covered by Keruing hardwood. Thanks to this flexible combination, the highly stressed ramp slopes are perfectly protected against wear whereas on the storage spaces the lighter hardwood is used.
For loading and unloading, the structure is supported by hydraulic supports in the area of the loading ramps. The hydraulic loading ramps – both designed as spreader ramps, are also covered by rubber metal and can be shifted hydraulically to the side.
Between the axles, there is a recess for the excavator arm. The front platform is surrounded by collapsible/plug-in side walls. Here you will also find the electro-hydraulic pump assembly with which all hydraulic functions of the trailer are supplied with oil independently from the tractor. A time-controlled lubrification system provides around 60 greasing points regularly with grease.
The low-loader trailer has a very wide equipment regarding the possibilities of load securing. There are 17 pairs of rigid lashing rings with each 10,000 daN on the vehicle. These ones are complemented by the award-winning Vario-Lash system only available at Langendorf. These ten additional lashing devices can also take up to 10,000 daN load.
At the joint booth of Wielton and Langendorf in the open-space-area, FN 827/1 the Waltrop-based company with long tradition presents a steel half-pipe tipper.
The exhibited vehicle of type SKS-HS 24-7.5 without chute has a volume of 24.3 m³ and comes equipped with BPW disk brake axles. The steel half-pipe in the exhibited design weighs approx. 6,100 kg.
The first axle is equipped with the Langendorf axle lift, an electro-pneumatic paver brake with automatic raising, automatic lowering during the tipping operation for higher stability during the tipping operation and RSS (roll stability support) supplement the chassis equipment. The vehicle's tires have Alcoa Dura Bright wheel rims.
Lighting is executed in full LED and complies with the state of the art. This also applies to the flashing side marker lights acc. to ECE 48 R-06. Two LED backup lights ensure perfect illumination.
The wall thickness of the front wall, made of high-strength fine-grain steel, is 4 mm inside and outside. Steps mounted on both sides allow comfortable access into the body.
The interior area of the side walls and back wall consists of 4 mm original Hardox HB 450, the bottom is laid out with 5 mm.
The tailgate with a 15° tilt is pendulum-mounted on top and automatically locked via two drawbars. The circumferential rubber seal is easily replaceable thanks to the special border profile.
A low pressure front wall press - 150 bar, 6,233 mm stroke - ensures the high tipping angle of over 52°. Among other things, a pressurized air manometer for weight control, a ladder as well as a broom and shovel holder complete the vehicle's equipment.
In vehicles with steel body, Langendorf uses only Original Hardox HB 450. The sheet thicknesses used in it vary depending on the customer's specifications.
In the open-space-area FN 827/1 the Waltrop-based manufacturer with long tradition presents a vehicle from the SB series to the specialized trade professionals. The completely revised Flatliner impressively shows the range of possible missions.
The inloader of type SB-19 H 95/81 is used on all continents under the name Flatliner. An important advantage is the loading and unloading that needs no aids like a crane or lift truck, as the Flatliner must only take in a pallet (flat) that already carries the load on it.
The shown inloader was subjected to an extensive revision. In the process, many details have changed, resulting in more customer benefits altogether, without changing the globally unique low weight.
The most important innovations include:
The door retainers are now significantly more robust - an important safety aspect when loading and unloading on uneven terrain in strong winds.
All side storage compartments have been redesigned and are now even better protected against the ingress of spray water.
The operating elements have been redesigned from an ergonomic point of view and - as the inloader is in use worldwide - provided with universally understandable lasered operating pictograms.
Maintenance openings in the shaft inside now allow a more comfortable access to the slack adjusters. Thus, the care and maintenance of these important components is much easier.
The worktop on the two long girders - also called girder grate - now consists of GRP. Long-term tests have shown that GRP is less sensitive to soiling and thus significantly increases the safety of the driver.
Other visible changes include the rear portal. The hinged underrun protection is now made of aluminum and – with the same strength - does not burden the driver during the folding process as strongly as the previous steel design. In addition, the 270 ° rear door can now be retrofitted with minimal effort into a combi-door. This was not possible before.
The sum of the changes has many effects on the daily operation with minimal design changes of the vehicle.
The handling of the vehicle for the driver is more comfortable, the entrepreneur can always retrofit many options without much effort. That was previously only possible to a limited extent.
Intended for use behind two- or three-axle tractors, the empty weight could be reduced to approx. 9,500 kg. Thanks to the technically advanced single-wheel suspension, the loading shaft has a length of 9,500 mm and a width of 1,550 mm. This makes it possible to transport loads that are more than 9 m long and up to 3.7 m high in the loading shaft.
Loads of these dimensions are generally transported with low-loaders, although due to the load height or width a special permit is often required. Most of the time, these transports are also linked to conditions. With the inloader, these requirements are frequently dropped, thereby providing maximum flexibility to the carrier.
Owing to the hydraulic lifting arm, no special technical requirements are needed on the tractor – any commercially available articulated truck can be used.
The hydraulics are self-sufficiently operated with the electric engine built in the trailer. The same engine also operates the fixing devices hydraulically. They can be adjusted horizontally and vertically so they can be flexibly adapted to the most varied loads and can be displaced in longitudinal direction on angled rails.
In addition, a telescoping of the fixing arms is now possible. Therefore, the operation is fully possible from the ground and thus ensures the safety of the operating staff.
Up to five flat pallets can be taken in empty runs. To minimize tire wear and tear, the first and third axle can be lifted.
There is also the load restraint tested by TÜV Nord in May 2008 acc. to VDI 2700.
The driver must only take in the pallet, secure it with the bracing device and can leave immediately. This means that the full loading process, including load securing, is completed in less than 10 minutes – TÜV-tested and -certified. In addition, the vehicle is equipped with seven pairs of lashing rings on the longitudinal beams and every lashing point can be loaded here with 7.000 daN.
The flat pallets necessary for this (also named flats) can be manufactured in the most varied ways for every type of load to ensure optimal travel within the supply chain. Just three flats make a continuous transportation chain possible.
In the front platform above the fifth-wheel coupling, on a length of about 3,000 mm, there is plenty of room for accessories, toolboxes and other auxiliary materials. The back wall and the two sidewalls of the platform are made of one piece and detachable, two pairs of lashing rings with 5,000 daN allow the load to be properly secured here as well. A left and right access ladder ensures safe platform access.
The single-wheel suspension in swinging execution is hydraulically operated for lowering it. The axle compensation of the axles among one another also takes place hydraulically and is cushioned by integrated hydro-pneumatic accumulators, thereby allowing a complete stroke distance of 430 mm.
Since the entire vehicle is hydraulically lowered for loading and unloading, all three axles have a built-in safety device to protect against an uncontrolled lowering when driving on the road.
An on-board electro-hydraulic pump assembly supplies the hydraulic restraining devices, two or three of them on each side, and the locking mechanism of the hydraulically locked tailgate. Built-in batteries allow operation independently from the tractor.
Spare wheels, accessories, a central lubricating system and other equipment items are stored under lock and key behind the full continuous aluminum enclosure. Working lights in all important points, pluggable rotating beacons and outlets for additional lighting complete the equipment of the concrete inloader.
