METZEN INDUSTRIES GMBH - When it really matters.

Hydraulic grab systems: efficiency is important for successful cargo handling. Our KROGER grabs with hydraulic technology improve your handling systems’ efficiency in multiple ways. Speed and long service life are recognised worldwide as the key factors for this efficiency. Our hydraulic grabs’ lightweight design, which optimises the machines’ load capacity and therefore maximises their handling scope, is also crucial, and part of KROGER’s measurable added value. Our variety of specific grab types and sizes – from the smallest standard hydraulic grabs to large, custom grabs – increases your efficiency and profitability with every lift.
