The specially developed brushless DC motor is crucial for the improved performance of the Safelog AGVs of the '21 generation. The low-wear and powerful drive ensures a significantly higher starting torque, so that transported goods can be moved easily up to the maximum load of the respective device. At the same time, the increased dead weight of the Safelog AGV M4 supports optimum power transmission. "With the drive, we can cover a wide range of speeds from 0.02 to a maximum of 1.6 meters per second. The reduced minimum speed opens up additional application possibilities in the field of mobile assembly systems," explains Managing Director Mathias Behounek. The maximum tensile load is still 1,500 kilograms, while the top load capacity has been increased fivefold to 1,000 kilograms. To transport and handle these higher loads, Safelog has equipped its AGV M4 with a sturdy steel chassis and an optional electric scissor lift. The lifting system, which is mounted on both sides, has a maximum lifting height of 40 millimetres to automatically pick up pallets and pallet cages as a top load.

Inductive charging system

With the '21 generation of appliances, Wiferion's inductive charging systems will become standard on all new Safelog AGVs. The previous charging system using copper sliding contacts will continue to be offered as an option. The energy supply to the AGVs via the Wiferion etaLINK 3000 charging system is fully automated during operation without interrupting the material flow. The charging process is wear-free, meaning that the working environment is not contaminated by abrasion, as is the case with sliding contacts. The base plate of the charging station can be approached from any direction. As soon as the receiver in the AGV is fully positioned above the stationary plate, the inductive coil is automatically switched on and charging of the LiFePo4 batteries starts. If no charging stop is planned, the charging plate can be driven over without reducing the process speed.

The new generation of devices can be used within a process with AGVs of older model types without any problems, as Safelog provides software updates across all generations. This means that swarms consisting of AGVs from different device generations can be operated together without any restrictions.
