The 711.0 series consists of nine vehicles built by Windhoff in Rheine in 1995 and 1996 for fault clearance and maintenance of overhead contact line systems . The name "HIOB" for the vehicles means aerial work platforms, maintenance vehicles, and catenary systems .
Vehicle number 711 001-8 was assigned to the Kar 6209 tunnel investigation vehicle until 1982 .
Structure and equipment
The motor coaches of the series have a 711.0 over the entire frame length ranging superstructure in lightweight steel construction. The car body contains a 8,060 mm long workshop space, driver's cab 1 with 2,400 mm long and the combined lounge with driver's cab 2. This is where the video workstation and the vacuum toilet are located .
On the roof of the cabin, starting above the driver's cab 1, there is a measuring current collector of the type WBL 85, the contact pressure of which can be regulated manually. This is followed by the contact wire and suspension cable lifting device from the manufacturer Atlas. Then there is a working platform with the dimensions 3,500 mm × 1,600 mm, which can be hydraulically raised by 1,400 mm.
The freely swiveling aerial work platform with the dimensions 1,500 mm × 1,600 mm can be combined with the aerial work platform. Both platforms reach a maximum height above SE of 5,200 mm in synchronism, the FHB alone up to 18 m. There is also a video camera that sends an image of the pantograph to the video workstation, from where the recordings can be recorded in real time.
Drive and brakes
All "HIOB" have a running and a motor bogie. Both are almost identical in construction and have two axles with monoblock wheels guided by mega springs . The vehicles are braked by a motor brake and a compressed air brake. The automatic indirect and the non-automatic direct air brakes act on cast iron brake blocks on all axles, both brakes are multi-release. An electropneumatically controlled spring-loaded brake is available to hold the stationary vehicle .
Drive and electrics
For a distance drive is MAN - Diesel engine of type D 2876 LOH 01 installed. This generates an output of 338 kW (460 hp) at 1,800 rpm from 6 cylinders using exhaust gas turbocharging with charge air cooling .
Power is transmitted to both axles of the drive bogie via a hydrodynamic gearbox . A 4-cylinder MAN D 0824 LFL 02 engine with 118 kW (160 hp) at 2,400 rpm was installed for the work trip. It drives a hydrostatic pump in order to use the generated oil pressure to drive a hydrostatic motor built into the drive train.
This design makes it possible to operate both motors in parallel for long-distance travel at higher speeds in order to obtain high performance.
Two power systems are installed for operation. A three-phase network 230/400 V with 10 kVA is available for the use of commercially available tools .
The entire vehicle is powered by a 24 V network, which draws its energy from batteries and alternators driven by the motors. The batteries can also be charged via a 230 V external voltage connection.
The car is controlled via an integrated vehicle control from Krauss-Maffei. This takes over the control, monitoring and diagnosis of all relevant functions. Drive and brake commands are issued via a combined drive / brake lever integrated on the driver's desk.
The manufacturer has an Indusi I 60R, a time / time Sifa and train radio . In addition, the installation of an LZB 80 was prepared. This is said to have been installed in vehicles 711 007 to 009. The two cars 003 and 005 still in use now have a PZB 90 and the train radio has been converted to a GSM-R device.
sale
The vehicles 711 002, 007 and 009 were sold to Railsystems RP GmbH in 2009 .
