Gravel extraction: KROGER grabs dredgers and rope extravators allow you to extract gravel and sand from rivers or lakes and have been used for this purpose in the toughest conditions across Europe for over 50 years. Thanks to our maintenance-free underwater motor and ropemechanical grab systems, you can extract gravel and sand in new locations whilst complying with environmental regulations and increasing your profitability. Our grabs are particularly suitable for use on difficult terrain and at extreme depths. Our latest record also bears witness to this: our experience paid off when KROGER grab became the European champion with a dredging depth of 177 meters during excavation in Lake Lucerne. Reliability matters – even when extracting gravel and sand at new depths.
