Just in time for the Sochi 2014 Winter Olympic Games, Russia opened its first large and modern leisure park. One of the most spectacular attractions of the Sochi Leisure Park was made possible by a Siebenhaar rope winch size 4100 WH. One hoist equipped with safety disc brakes for each of the two towers is used to pull up the car, then it is shot from the free fall and, following several looping repeats, it is pulled up on the other tower.
We welcome the newest member of our ultra-modern machinery! It is a Liebherr LC 380 hobbing machine with automatic workpiece feed. Workpieces can be machined up to a maximum diameter of 380mm and up to Module 7.
From August 2015 Siebenhaar Drive Technologies delivers its first free-fall winch Type 4099 WF featuring a maximum wire drive of 45t in normal operation and 22.5t in free-fall mode.
For the first winch the field of use will be a crawler crane operation.
This year we celebrate our 50th anniversary since the founding of Siebenhaar Antriebstechnik back in 1965.
To all our customers and suppliers we thank you for your successful cooperation. Together with our existing and future business partners we are looking forward to many more years to follow.
Commissioned by Van Haagen Kraanbouw Siebenhaar Antriebstechnik has developed and build the winch system for a very large gantry crane in Szczecin (Poland) with a lifting height of more than 100m, a span of 50m and a total lifting capacity of 1,400 tons. This makes it Europe's largest crane of its kind. The crane is used for building, loading and unloading windmill foundation inserts. The main specifications of this gantry crane are: Altitude 120m, lifting height more than 100m, 50m span, total lifting capacity of 1,400 tons (4 × 350 tonnes). The winches are placed at the bottom of the undercarriage. The winches are capable to work with very high speeds to be able to spool on / off a large amount of steel wire rope. The winches are driven by electric motors with a speed of 4500 / 5000 rpm, 200kW. The winches have a line pull of 42T with a rope storage capacity of 1050 m which is spooled on a special parallel grooved pattern in multiple layers.
