The DH 90 from Translok GmbH is a shunting locomotive with hydrostatic power transmission and single-wheel drive in the lower performance segment. The locomotive was developed in the 1980s by Allrad-Rangiertechnik GmbH in Heiligenhaus in North Rhine-Westphalia. It was initially marketed by the company Zwiehoff, Rosenheim under the name minilok and is now being developed, offered and maintained by Translok GmbH.
The spacious driver's cab is arranged in the middle and is noticeable for its particularly large panes that almost reach down to the floor level at the front. The vehicle can be delivered with a wagon brake system, radio remote control, automatic shunting couplings, in various track widths, with air conditioning, particle filter (TIER IIIb) or double traction control (in connection with a radio remote control). If the locomotive is operated via a radio remote control, this is also used when the driver is in the driver's cab. The vehicle can leave the rails on the solid rubber wheels by folding in the tracking device.
In total, a good dozen locomotives have been delivered to date, the first of the earlier deliveries are out of service.
technology
The DH 90 has a hydrostatic drive, as it is mainly used in the construction machinery sector. The diesel engine drives a hydraulic pump and each wheel is individually driven by a hydraulic motor, i.e. H. there are no axles or wheelsets in the actual sense. This technology makes it possible to apply the full tractive power from the state and to drive at a very low continuous speed of only 1.5 km / h under full engine load. The pressure in the hydraulic system is up to 420 bar.
The drives can also be used for braking in order to protect the mechanical brakes.
To reduce costs, components from the automotive and construction machinery sectors were used as much as possible in the development of the locomotive.
