LZB54-LB series air motor with integral fail-safe brake for heavy loads.
Air Motor with Brake LZB54-LB delivers robust safety and holding power for heavy-duty industrial applications. This series combines a powerful pneumatic motor with an integrated brake module, ensuring secure load retention and precise stopping capability without relying on external power sources.
The braking system in the LZB54-LB operates on a “Fail-Safe” principle: a heavy-duty spring engages the brake instantly when air pressure drops or is cut off, mechanically locking the drive shaft. The brake releases only when air pressure is applied to the motor. This functionality makes it the ultimate choice for lifting equipment, hoists, inclined conveyors, and indexing machinery where load slippage poses a safety risk. Atlas Copco designed these motors for Lubrication Free operation, maintaining a clean environment and ensuring consistent performance over time. With braking torques reaching up to 280 Nm, this motor provides reliable control for demanding tasks. Furthermore, every unit in this series is fully ATEX Certified, ensuring safe operation in hazardous environments.
