There are various technologies for barrier. One of them is manual delta barrier, which is widely used due to its reliability. The other technologies are often manufacturer specific. These delta barrier can run continuously without generating heat, so boom barriers can be operated continuously and in an intensive duty cycle.
Manual delta barriers are rising arm barriers that are manually operated to control vehicle access. Manual barriers are ideal for parking control, road access and traffic management requirements.
Manual barriers is designed to close off one or two lanes of a roadway and provide counter terrorist level protection against vehicle attack. The barricade stops a 15,000-pound (66.7 kN) vehicle traveling 50 mph (80 kph) with zero penetration. It meets the K12 crash certification standard set by the United States Department of State.

With a 24-inch (61 cm) shallow foundation and fully enclosed, flush mount design, the HD200 obviates the concerns of interference with buried pipes, power lines and fibre optic communication lines in urban applications. The shallow foundation also reduces installation complexity, time, materials and corresponding costs. The HD200 is perfect for high water table locations and areas with corrosive soils. It provides low maintenance as its totally enclosed face is easily removed for access.
Leveraging the latest technologies, the HD200’s breakthrough EFO can be remotely controlled via fiber optics, touch screen control panels, NEMA rated control button panels and simple key switches. The HD200 barrier also features a full range of diagnostic indicators for early detection of any difficulties.
As with most other Delta barricades and barriers that are properly maintained, projected life expectancy of the HD200 is 20+ years.

|Gear Tech DSC7000 beam barrier is used where wide roadways need to be secured from attacking vehicles. The 725-pound beam of the vertical lift barricade stops a 15,000-pound (66.7 kN) vehicle traveling 50 mph (80 kph) dead in its tracks, equivalent to 1.2-million foot-pounds of kinetic energy. The DSC7000(H) version operates remotely by means of an integral Hydraulic Pumping Unit (HPU) that is wholly enclosed in the hinge end enclosure. The HPU can be powered from a local single or three-phase power source. The Manual version of the Model DSC7000 Drop Arm Beam Barrier System can be converted to fully automatic operation by the addition of a Delta hydraulic power unit and appropriate control options.
