Aluminum Drop Arm with Counterbalanced Operation
Lightweight, High-Strength Aluminum Arm
Mantis drop arms are constructed from structural-grade aluminum, providing an ideal balance of strength, durability, and corrosion resistance. Aluminum construction keeps the arm lightweight while maintaining rigidity, reducing operator fatigue and long-term wear.
Integrated Counterweight System
A precisely engineered counterweight mechanism for Drop Arm Barriers is built into each system. This system offsets the weight of the aluminum arm, allowing the barrier to be raised and lowered smoothly and effortlessly by a single operator.
-
Minimal lifting force required
-
Controlled, steady motion
-
No sudden drops or rebounds
-
Safe and predictable operation
The counterweights are enclosed and protected from the elements, ensuring consistent performance over time.
No Power. No Controls. No Electronics.
This barrier requires no electricity, no wiring, and no control systems. Mantis has no motors to fail, no PLCs to troubleshoot, and no access control devices required to operate the arm.
This makes it an ideal solution for:
-
Remote or undeveloped sites
-
Temporary or semi-permanent access points
-
Facilities looking to reduce infrastructure costs
-
Locations with unreliable power
-
Projects requiring rapid deployment
Operation is fully manual and intuitive, requiring no special training.
Concrete Base Mounted for Stability and Longevity
The barrier is mounted to a site-poured concrete foundation, providing a stable, tamper-resistant installation. The concrete base distributes loads evenly and ensures the upright remains rigid under repeated use and environmental stress.
-
Engineered foundation dimensions provided
-
Suitable for asphalt or concrete roadways
-
Long-term structural stability
-
Resistant to shifting or settlement
Virtually Maintenance-Free Operation
With no motors, hydraulics, or electronic components, maintenance requirements are minimal.
