Long outreach and high stability when used on wind turbines with the RUTHMANN T 900 HF
With the cable winch in the workman basket, material can also be retrieved into the workman basket at a working height of 90 metres without having to interrupt the work platform operation.
The RUTHMANNSTEIGER® T 900
HF RUTHMANN STEIGER® T 900 HF was launched in 2018 and has since demonstrated its impressive performance data in thousands of applications.
Whether recovering scaffolding parts from the burnt-out NotreDame church or in the rough terrain of Spanish wind farms, the RUTHMANN T 900 HF is unique on the market with its 36 metre outreach, which it can achieve at a height of 62 metres.
RUTHMANN is planning the world premiere of the RUTHMANNSTEIGER® T 1000 HF with a working height of 100 metres for 2024. It will top these figures once again.
The Spanish company GRUPO ROXU received a RUTHMANNSTEIGER® T 900 HF from AMCO Machinery & Consulting, the official RUTHMANN sales and service partner in the Spanish market, at the beginning of 2023. Grupo Roxu’s customers also include the operators of large wind farms in Spain. They are increasingly focussing on the use of modern access platform technology,
as this can greatly reduce the maintenance and downtime of wind turbines compared to conventional scaffolding solutions.
The RUTHMANNSTEIGER® T 900 HF offers many advantages over the competition.
Flexible use in wind farms
Built on a 5-axle Scania chassis, the STEIGER® T 900 HF is ideally equipped for use on the difficult terrain of Spanish wind farms. Even without four-wheel drive, it reliably reaches the work sites thanks to its optimised weight distribution. The Scania chassis offers stable driving and cornering behaviour in the many hairpin bends on the access roads through the mountainous landscape.
At the wind turbine, the wind turbine operator benefits from the fully variable support of the machine, which, in conjunction with the Dynamic Reach System (DRS), offers the maximum possible performance data with limited support options in the terrain. These can be further increased by limiting the basket load, for example, and offer service
GRUPO ROXU has also had the T 900 HF equipped with a lift-up system for convenient material lifting.
High stability thanks to two operating modes
The upper boom of the T 900 HF, which is around 33 metres long, gives the working platform an unusually high degree of flexibility and a long reach, especially above the articulated joint at a height of around 60 metres. The two working modes, HeightPerformance and SkyPerformance mode, ensure maximum stability by locking the lower telescope. This ensures extremely high stability at all points of the huge working diagram. In practical use at the wind farm, this means that the rotor blades can be approached very closely without the risk of them being touched or
technicians a very large working area that can be utilised without having to move the machine.
The “wind speed” DRS function is particularly popular for use in wind farms. While competitor machines have to stop working in high winds, DRS users can continue working in a relaxed manner. The DRS automatically adjusts the maximum working height to the current wind force.
Thanks to the long outreach of 43 metres and the Highflex technology, it is possible to work on a very large area without having to move the work platform, which is timeconsuming.
The HighFlex technology in the name of the RUTHMANNSTEIGER® T 900 HF makes it possible to inspect the rear of the rotor blades and check for possible damage by rotating the working cage by up to 440 degrees. If damage to the rotor blade is detected, it can be repaired immediately without losing any time. 230 V and 400 V sockets for power tools are provided in the basket, e.g. for using grinding machines to grind out damage.
