And a Service Lift – or Work Cages – is the safest way to bring technicians up and down in the turbine tower. More than 16.000 Service Lifts are produced by Avanti Wind System and installed in wind turbines all over the world – the turbine owners have realized that an Avanti Service Lift is a good investment offering the highest safety to the technicians working in the turbines. With a Service Lift the technicians do not have to climb up and down the tower using a ladder. The Service Lift takes them and their tools quickly and safely to the turbine nacelle. And the lifts are designed to be taken into operation even before the wind turbine is ready to produce power. Consequently, the equipment can be transported within the tower and to the nacelle using the lift. The Avanti Service Lifts can be mounted in any type of wind turbine tower. Avanti engineers are constantly developing updates and new Service Lifts systems to meet all industry needs. AVANTI DOLPHIN SERVICE LIFT AVANTI SHARK SERVICE LIFT AVANTI DOLPHIN SERVICE LIFT Avanti Dolphin Service Lift is guided on wires. It can carry two passengers and their equipment. It can be used in all brands and types of turbine towers. The Service Lift is guided through openings in the platforms operating completely independently from the ladder system in the tower. The lift is constructed in a self supporting aluminum plate structure without carrying frame. The lift is seawater resistant and it can of course be used in offshore turbines, too. The Avanti Dolphin Service Lift has a newly developed fully integrated interlock system for doors and fences. It has a sliding door that can be horizontally divided in two. The lower part works like a door, the upper part like a window. The Service Lift can only be operated with the doors closed. But the lift can be put to a stop anywhere in the tower, and the upper part of the door can be opened and the technicians are able to perform service from the lift – or they can use their safety equipment and climb the ladder system. The lower part of the sliding door can only be opened when the lift is put to a stop at the platforms or at the bottom of the tower offering safe and easy entrance and exit for the technicians and their tools to and from a platform. When the door is closed, the lift is operated with a hold-and-go system called a dead-man's switch. The Service Lift stops immediately when the switch is released or the door is opened. If there is a power loss in the turbine, the lift can be operated manually. It can be lowered slowly and safely to the bottom of the tower, or the upper door can be opened anywhere and the technicians are able to climb down using PPE anchor points with their safety lines attached to the ladder system. Avanti Dolphin Service Lift has different new features; among them side windows and an inspection window, service of traction wires and safety wire. The motor and the power supply of the lift are located on top of the lift cabin. A solid beam with the motor wire, two thick guide wires and a safety wire are installed on top of the turbine tower. The three wires are mounted and tightened in the basement of the turbine tower. Avanti has developed a Tension Spring System to tighten the wires. Avanti Wind System has developed a flexible wire guide ensuring that the lift is steered smoothly through the wind turbine platforms with a few centimetres between the lift and the platform. The electric cable to the lift is housed in a cable collect bin under the basement in the tower. The cable coils up in the bin when the lift is running down meaning that there is no risk of wear or damage to the electrical cable due to oscillation and vibrations when the turbine produces power. The noise level is 72dB at start and drops to 70 dB when running, which is not disturbing – it is the same level as a normal TV-audio level or as a vacuum cleaner e.g. One-stop-shopping Avanti Wind Systems has office locations and factories all around the world. Avanti also produces complete internals sets for wind turbine towers.

The standard model can carry two passengers and their equipment. It can be used in all brands and types of wind turbines. The Service Lift is guided through openings in the platforms. It operates completely independently of the ladder system in the tower. The lift is constructed in a self-supporting aluminum plate structure without carrying frame. It is seawater resistant and can of course be used in offshore turbines, too. Several models with different door-systems are available – two doors, four doors, sliding doors or roller doors. Avanti Service Lifts are always designed to meet customer-specific needs with regard to door systems, lift size and shape - but never at the expense of safety. Safe work in wind turbines always has top priority at Avanti. The Service Lift can only operate with closed doors. But the lift can be put to a stop anywhere in the turbine tower, and the technicians can climb out, or they can work from the lift without climbing out – the closed lower part eliminates the risk of falling out. One model of the Avanti Shark Service Lift is closed 110 cm from the bottom of the tower. The technicians open the upper door to enter and a 110 cm tall fence around the openings of the platforms is also used as a small ladder for the technicians when entering the Service Lift. Avanti produces another model which also allows two lower doors to open at the platforms - and only at the platforms - when normal power supply to the lift is available making it easier to transport heavy tools and materials in and out the lift. The models with another door system have as standard a 10 cm toe board installed to avoid tools and other items from falling from the floor of the Service Lift down into the tower. The different requirements to the dimensions and the shape of the fence around the openings of the platforms vary from country to country. Avanti can deliver and install the solutions required by law and according to what the customer wants – with safe work in wind turbines as top priority. When the doors are closed, the lift is operated with a hold-and-go system called a dead-man's switch. The Service Lift stops immediately when the switch is released or the door is opened.
