Maximum Tightness and Reliability in Hazardous Waste Handling

Baseline Situation

  • A leading hazardous waste company needed to safely handle solid and liquid waste in a sealed bunker.

  • Grabs had to operate continuously in liquids, conveying and pre-mixing materials under extreme conditions.

  • The aggressive environment and sealing requirements placed high demands on mechanical and electrical components.

  • The solution had to prevent liquid ingress, ensure maximum safety, and enable stable, efficient operation.

Solution

To meet the demanding requirements of hazardous waste handling, the team developed specially adapted motor-hydraulic grabs with a capacity of 800 litres. They were designed to operate reliably in liquid depths of up to 1.5 metres. All hydraulic and electrical components were engineered for maximum tightness. A pioneering innovation was the direct integration of the power cable into the motor, eliminating the need for conventional junction boxes. In addition, a robust plug connection was installed above the grab to ensure safe power supply even if the grab tilts.

Result

The specially developed grabs meet the complex requirements of hazardous waste handling while ensuring maximum reliability and operational safety. Through innovative cable integration and high-quality sealing technology, all challenges of the extreme working environment were overcome. The result is a system that optimally combines efficiency, safety, and durability, making a significant contribution to modern hazardous waste processing.
