Description

The CAME GARD LT4 Automatic Barrier Kit (often referenced by package codes 8K01RB-0720 for the rectangular boom kit or 8K01RB-0722 for the tubular boom kit) is a heavy-duty, rapid vehicle access control system.

Positioned as CAME’s value-driven champion for medium-to-high traffic sectors, the LT4 offers exceptional commercial longevity, boasting a tested 1.5 Million MCBF (Mean Cycles Between Failures). Powered by a 24V DC encoder motor managed by a ZL392-C digital control board, this system is engineered to secure residential parking lots, commercial entrances, and private access roads with an absolute net clearance width of up to 4.0 meters.

Core Engineering Innovations

• Advanced Speed Control (ASC): The LT4 features an active force-profiling system. Its onboard firmware constantly analyzes the wind load, drag, and weight distribution acting on the boom. It automatically calibrates acceleration and deceleration speeds to provide highly smooth end-of-travel slowdown curves, which radically preserves the internal structural gear teeth.

• Single-Spring Multi-Point Balancing: Installers no longer need to carry or specify different spring rates for different driveway spans. CAME engineered a variable balancing lever directly inside the cabinet; the same heavy-duty spring can be adjusted manually to balance booms anywhere between 2.5m and 4m by simply altering the mechanical hook-up point.

• Upright-Safe Maintenance Layout: The digital control board is housed in an isolated ABS enclosure positioned directly beneath the cabinet’s upper cover. This allows technicians to comfortably program, troubleshoot, and perform system health checks standing upright without needing to remove the entire front panel.

• Native Modbus & Cloud Architecture: The motherboard features serial ports natively designed to communicate via MODBUS protocol for clean building-management or third-party parking system integrations. It also supports seamless connection to the CAME CONNECT cloud network for full remote configuration and smartphone toggling.
