Explosion Proof Belt Driven Modular Actuators
The carriage is driven by an external linear belt that can be adjusted to reduce lash and is driven along the external roller bearings. The pulleys have maintenance-free ball bearings. Belt tension can be readjusted by a simple screw adjustment device in the carriage.
The ELFZex is a carriage driven actuator with single fixed belt. Because the single belt wraps around with both ends and is fixed to the carriage, a larger capacity can be realized.
The ELFZ and the ELFZex belt driven modular actuators are suitable for use according to the intended purpose in potentially explosive areas (see ATEX 95 marking). An operating manual is included in the scope of delivery. The system is certified for the following areas:
ATEX 95 II 2G EEx c IIB T4:
All application areas except for underground mining. Gas atmosphere category 2, explosion protection category: protection due to secure construction (design security). Equipment group IIB. Temperature class T4=135°C
ATEX 95 II 3D T125°C:
All application areas except for underground mining. Dust atmosphere category 3. Maximum permissible surface temperature: 125°C.
