New city crane from Wolffkran

Tower crane manufacturer Wolffkran has launched a new city crane, the Wolff 5014, a flat top design.

The crane was designed by engineers from the Heilbronn factory in Germany. It has a tip load capacity of 1.4 tonnes at a 50 metre radius and a lifting capacity of 6 tonnes. The Wolff 5014 can be erected up to a hook height of 43.5 m using TFS 15 tower sections.

A hook path of up to 190 m is possible with the frequency-controlled 28 kW hoisting winch. Gerd Tiedkte, Wolffkran product manager, said, “With this winch, the 5014 city can achieve a considerable handling capacity with partial load speeds of up to 108 m/min when lifting loads of up to 1.1 tonnes.”

For easy assembly, the entire jib, including the reeving of all ropes, can be assembled on the ground. On more confined construction sites, the jib can also be assembled in the air, the manufacturer said. The city crane can also be operated with or without a cabin. It has a radio remote control transmitter with a digital display and is fitted with a crane control system, which can be used to adjust drive performance and assist the operator, the manufacturer added.

It also has the Wolff Boost function to give 10 % more lifting capacity when necessary, a spokesperson added.

The new model was launched at the construction equipment exhibition in Bern, Switzerland, 18 to 23 March.
