Answer:
The AZBB115 movement features a die-cast aluminum alloy chassis housing a three-stage reduction gear train made from carburized, precision-ground SCM421 alloy steel. During a power failure, the boom arm can be manually lifted directly by hand without declutching.
The Autozon AZBB115 core drive incorporates several structural and mechanical engineering features designed for heavy-cycle vehicular access:
- Die-Cast Aluminum Movement: The movement body is cast from aluminum alloy via a high-pressure die-casting process, providing dimensional accuracy, structural rigidity, and heat dissipation under continuous duty.
- SCM421 Gear Reduction: The drive system utilizes a three-stage gear reducer constructed from SCM421 alloy steel subjected to carburizing heat treatment and precision grinding. This delivers higher wear resistance, shock loading tolerance, and service life compared to traditional worm-gear gearboxes.
- Brushless DC Motor: A compact 24V BLDC motor provides high output torque with electronically governed deceleration buffering at fully open and fully closed limit positions to suppress mechanical rebound.
- Direct Manual Override: In the event of a power outage, operators can lift the boom arm directly by hand without requiring clutch disengagement keys or mechanical release tools.
- Mounting Architecture: The movement employs a side-stick cabinet installation layout for compact footprint and service access.
