MANTIS Mobile Drop Arm Barrier
Heavy-Duty Portable Road Closure Barrier & Manual Vehicle Access Control Gate
Portable. Powerful. Simple. No Electricity Required.
The MANTIS Mobile Drop Arm Barrier is a heavy-duty, portable vehicle access control gate designed to secure roadways, restrict unauthorized vehicle entry, and provide a highly visible traffic control solution without permanent installation. Engineered for commercial, industrial, military, and government applications, the MANTIS combines rugged construction, exceptional portability, and effortless manual operation in one versatile roadway security barrier.
Unlike conventional automatic barrier gates that require electrical power, underground wiring, concrete foundations, and expensive installation, the MANTIS is a completely self-contained portable drop arm barrier that can be deployed quickly using a forklift. Its substantial concrete base, hot-dip galvanized steel framework, and precision-balanced counterweight mechanism provide dependable operation in demanding outdoor environments.
Whether securing a military installation, controlling deliveries at a data center, restricting traffic at a construction site, or temporarily closing a city street, the MANTIS provides a practical, economical, and highly visible solution for vehicle access management.
Heavy-Duty Concrete Base – Built for Stability and Portability
The foundation of the MANTIS Mobile Drop Arm Barrier is its substantial 2,000–3,000 lb concrete base, designed to provide stability while allowing the entire barrier assembly to be relocated as needed.
Unlike permanently installed security gates, the MANTIS requires no excavation, concrete footings, anchor bolts, or underground utility connections. Its freestanding construction makes it ideal for temporary road closures, changing construction environments, seasonal security operations, and facilities requiring flexible vehicle access control.
Integrated forklift pockets allow the barrier to be lifted, transported, loaded onto a trailer, and repositioned using standard forklift equipment.
Key advantages include:
Heavy-duty concrete base weighing approximately 2,000–3,000 pounds, depending on configuration.
Integrated forklift slots for convenient loading, unloading, and relocation.
Freestanding design requiring no permanent foundations.
Suitable for asphalt, concrete, and appropriately prepared level surfaces.
Easily repositioned as security requirements or traffic patterns change.
Ideal for temporary, seasonal, or long-term roadway access restrictions.
The MANTIS combines the stability of a substantial concrete foundation with the flexibility of a portable vehicle barrier.
Precision-Balanced Manual Drop Arm – Effortless One-Person Operation
One of the most distinctive features of the MANTIS is its innovative counterweighted manual drop arm mechanism.
The barrier incorporates a heavy-duty steel pivot assembly and precision-balanced counterweights that offset the weight of the extended aluminum barrier arm. This balanced design allows a single operator to raise or lower the arm with remarkably little effort.
The MANTIS can be operated with just one finger.
There are no electric motors, hydraulic pumps, batteries, control panels, or complicated mechanical systems to maintain.
The manually operated barrier arm can be secured in both the raised and lowered positions, allowing authorized personnel to control vehicle movement through restricted entrances.
This simple, reliable design is particularly beneficial at remote locations, temporary security checkpoints, construction sites, military installations, and facilities where electrical power is unavailable or impractical.
