EKDR-Bas low-headroom travelling hoist:allows optimum utilisation of space

Universal travel wheels made of steel for travel motions that are gentle on the rails. The integrated drop-stop provides for additional safety.

Travelling hoistsThe travelling hoists are equipped with four flangeless universal wheels and guide rollers for low-noise and low-wear travel motions. They can be fitted with a thrust rocker or counter-weights. The travel units provide:

■■ stepless adjustment to the required flange width across a wide range

■■ precise and reliable travel even under arduous conditions, for example, if the runway is dusty or irregular.

At a glance

■■ Excellent approach dimensions thanks to compact design

■■ Optimum utilisation of the space available

■■ Various hook paths for different building heights

■■ Drop-stop arrangement■■ Integrated guide rollers■■ Load capacities up to 12.5 t■■ Optionally equipped with counter-weights or as a weight-saving model with a thrust rocker arrangement.
