Manually Deployable Drop Arm Barriers – Concrete Base Mounted
Simple. Reliable. Effortless Manual Control.
Our manually deployable drop arm vehicle barrier with a concrete base is a cost-effective, mechanically balanced access control solution designed for sites that need dependable vehicle control without power, controls, or electronics. Engineered for long service life and ease of use, this barrier is ideal for permanent or semi-permanent installations where simplicity and reliability matter most.
Purpose-Built Manual Design : Drop Arm Barriers.
Unlike powered barriers that rely on motors, wiring, control panels, and ongoing maintenance, this system operates entirely through mechanical balance and gravity. The result is a barrier that is:
Always operational
Immune to power outages
Simple to deploy
Extremely reliable
Low total cost of ownership
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.
Typical upkeep includes:
Occasional visual inspection
Lubrication of pivot points as needed
Periodic fastener checks
There are no service contracts, no calibration requirements, and no consumable components, making this barrier one of the most maintenance-friendly vehicle control solutions available.
Affordable Access Control Solution
By eliminating power infrastructure, control systems, and complex components, this manual drop arm barrier delivers significant cost savings:
Lower initial purchase price
Reduced installation cost
No electrical work required
