Updated: 7 days ago
The SAFELOG M4 is a mid-size mobile transport robot offered in three versions, from the German maker SAFELOG. The manufacturer does not publish a price. This review covers its versions, specifications and uses.
Quick Verdict
The M4 is long and flat: 1.46 m by 45 cm and 22 cm high. That shape slides under long trolleys and frames. The three versions cover most transport jobs in an assembly plant. The core carries 300 kg, the tow pulls 1,500 kg, and the lift, 15 cm wider, raises 1,000 kg. All use the same navigation options and inductive charging as the smaller S3.
