The panther T3E-0S3FZ25 features 3 axles, independent wheel suspension or panther double transverse axle, gooseneck with central mount and 25-ton fifth-wheel load. With a payload of up to 46,550 kg, the payload-optimised vehicle is suitable for transporting a wide variety of construction machinery. The vehicle has a width of 2750 mm across low-bed and the chassis ensures that the centre of roll of standard crawler chassis does not stray from the frame. The detachable gooseneck with ramps that retract into the low-bed is a useful addition. A wide excavator trough that is open at the rear provides further flexibility. The minor height difference of just 490 mm between low-bed and rear running gear offers additional benefits when transporting screening plants with low conveyor belts.
Added convenience is provided by the DOLLtronic control concept which is supplied as standard equipment with panther vehicles. The concept enables all the trailer functions to be controlled via separate keypads at the rear and on the gooseneck or using wireless operation. Feedback on the wireless remote-control display enables drivers to monitor many aspects of the vehicle and its operation from up front. Loading and unloading can be completed more quickly and drivers do not have to get in and out of the vehicle as often. The computer-assisted control concept, which is based on CAN bus, also supports permanent monitoring of all positions. Ride heights can even be adjusted during travel. The raising and lowering equipment has a total stroke of 315 mm (–110/+205 mm). There is also an integrated “spirit level function” for consistent ride height on terrain that slopes away steeply to the side (ride heights can be set separately on either side).
The other highlight at DOLL booth was a telescopic semi low-loader with positive hydraulic steering from the VARIO S4H-GR3S18 series, equipped with DOLLtronic and DOLL connect trailer management system. The VARIO semi low-loader benefits from corrosion protection in the form of the very high-quality zinc-rich primer with enamel finish, which is a standard feature. Alternatively, DOLL can offer zinc spraying or, as in the case of the panther mentioned above, a KTL primer followed by powder coating.
A VARIO N4S-0195 4-axle trailer was also exhibited at the show. DOLL is currently offering self-steering trailers with three, four or five axles. When these are combined with 2-axle or 3-axle dollies, load lengths of up to 80 metres and payloads of up to 85 tons are possible. Other defining features include three heights with three different sets of tyres.
The 4-axle vehicle on show featured special load-securing equipment for concrete blocks, spindle-adjustable stakes and inclined braces. The trailer can also be used to transport other types of long material and rotor blades.
